Be careful with hanging unsecured loads. Fig. 5. Fig. 4. 7 2.2. General safety instructions Observe the designated safety distances while operating the machine. The responsibility for injuries caused to others lies with the operator. Make sure that there are no people inside the operating zone before setting off. Avoid driwing on side slopes. Avoid abrupt movements. Always observe carefully the functions of the machine during operation so that you are able to stop the machine immediately in case of malfunction or danger. To avoid any consequential damage or accidents, stop the tractor and the drill immediately in an emergency situation. Make sure that the covers and safety equipment are always in place during operation. Always stop and switch off the tractor engine before carrying out any maintenance. Performance of maintenance, adjustment and any other work are prohibited while the machine or a part of it is elevated, unless the machine is supported in a due manner. To prevent the machine from moving or falling over, carry out all maintenance work on an even and firm surface. It is forbidden to go under an unsupported drill! Make sure that the lighting and other conditions are sufficient when using the machine. 2.3. Safety instruction for Multiseed IIt is expressly forbidden to stand a top the Multiseed at any time, except when filling tanks. The minimum safe distance from equipment in operation is three (3) meters. Observance of this is particularly important with row marker equipped Multiseeds, in which the markers are automatically switched to lift. Whenever performing maintenance tasks, the tractor engine must be turned off and the equipment supported with sturdy braces to prevent any movement. If it is necessary to go underneath a raised Multiseed for performing maintenance, 8 cleaning, and/or other tasks on the coulter section, then the equipment must be mechanically supported in its raised position, thus preventing any movement of the Multiseed or its coulters. also coulter section ball valve (3) (Fig. 39, page 27) must be closed. On top of the rear harrow, there is a rod (1) locked into place with a cotter pin (2), which can also lock the coulters into the upper position. Release the rod (1) and feed it through the coulter section loops (3). Fig. 6. Fig. 7 The rear wheel arms can be locked up over the outermost wheel pair cylinders with a maintenance brace (4). Maintenance braces are stored on the frame beside the rear carriage hydraulic lines. There are rubber loops on the frame for securing the braces. Remember to remove the rod (1) from the coulter section and the maintenance braces from the cylinder heads after maintenance/cleaning ! Reattach the rod to the top of the rear harrow. This is important, as the rod also serves as a weight for the rear harrow. Fig. 8 Never go under an unsupported drill ! 2.3.1. Warnings and prohibitions It is strictly forbidden to stand or sit on the drill when it is moving. It is forbidden to go under an unsupported drill. Do not let the drill move backwards when the coulters are pushed in the soil. Only use as standing platforms structures expressly intended for this purpose, other structures can be slippery. 9 When filling the hopper from large bags, make sure that the bag does not swing against the hopper. Hopper must be empty during repair or maintenance. Do not use the drill for purposes other than fertilizing, sowing and sowing with fertilizer. 2.4. Operating instructions for rims The manufacturer of the rims used in Kongskilde Juko machines has given the following instructions concerning its products: 2.4.1. Rim Rims are important components that affect the safety and driveability of the vehicle. Rims must be free from defect and approved for use both with this particular tyre and vehicle. NOTE! Never make modifications or repairs to the rims. There are several things that affect safety. Responsibility for any alterations and repairs that conflict with the instructions issued by the manufacturer falls on the person who carries out such alterations or repairs. 2.4.2. Fitting and removing the tyres The fitting of the tyres may only be carried out by a skilled professional with appropriate training and experience as well as the appropriate tools. Improper fitting can cause damage and constitutes a safety risk. 2.4.3. Retightening In normal cases the attachment bolts and nuts of the rims shall be retightened after the vehicle has been used for a while after fitting of the rims. Follow the instructions issued by the manufacturer of the vehicle. 2.4.4. Repair of the tyres A tyre must not be repaired while fitted on the rim, as the inspection of the inside is impossible.

General presentation Using modern agricultural technologies, today’s farmer strives to obtain the largest and highest-grade crop with the lowest production costs possible. Seeding/fertilization increases the crop’s utilisation of nutrients as the fertilizer is laid in moist earth near the seed. This ensures the fastest germination time and maximizes on short vegetation periods. The Demeter Multiseed was developed for all grains, oleiferous plants, and grasses and their simultaneous fertilization under Nordic farming conditions (combi version). Demeter Multiseed is also available as seed only version (seeder). Due to the unique coulter section, it is possible to seed both in tilled soil and in untilled beds under optimal conditions. The Demeter Multiseed is also designed to handle particularly large seeding areas under demanding and heavy use. Due to its strong base structure and high-grade materials, the Demeter Multiseed offers a durable solution for effective farming for years to come. The Demeter Multiseed meets all the latest standards for modern farming. The stepless feed regulator ensures the most accurate and consistent seed amount, as well as guaranteeing excellent conditions for a large, high-grade crop. The feed precision and stability of the feed equipment has been deemed outstanding in several official tests. Standard equipment: Stepless feed adjustment Fertilizer and seed screens Adjustable middle wall between fertilizer and seed hopper Seed and fertilizer agitator axle Calibration test system for both fertilizer and seed units Seed and fertilizer disc coulters, diam. 40 cm Electric area meter Automatic electrohydraulic row markers with tine Electric system with connections for optional equipment Semi-lift equipped rear harrow with diam. 12 mm tines Adjustable drawbar Taillights Footstep Optional equipment: Tramling device Hydraulic leveling board with single or double tool bars Inter wheel packer Grass seed/start fertilizer seed hopper Seed or fertilizer feed electric remote control Slave cylinder Independent row marker controls Seed dressing device Rear wheel stone protector Draw bar adjusting cylinder Max-Flow rearharrow with diam. 10 mm tines Pre-emerge marker Tractor pattern front wheels Disc row marker 12 3.2. Hitch introduction 3.2.1. Swivel hitch connection The Multiseed comes with a swivel hitch which is mounted to the tractor lifting arms. (Fig. 10) Hitching using the swivel hitch. Fig. 10 Hitching using the drawing hook. Fig. 11 3.2.2. Hitching directly to the drawing hook (optional ) A hitch connection will require a towing bar in place of the swivel hitch (fig. 11). 3.2.3. Hitching when an inter wheel packer is used (optional equipment). The packer is installed instead of the swivel hitch (Fig. 12). Inter wheel packer is used when it is desired that the entire seeding area be compacted, for example, to ensure an even germination. Hitching as the inter wheel packer is used. Fig. 12 Important ! The wheel packer must always be raised when reversing. If the roller is touching the ground when reversing, the wheels will turn in on themselves and the roller can break. 13 3.3. Hopper introduction Demeter Multiseed 3000 and 4000 combi drills are equipped with large capacity hoppers with an adjustable intermediate wall (A) between the fertilizer and seed units. Thanks to the adjustable intermediate wall, the volume of the hopper can be fully utilized regardless of the required quantity of fertilizer and seed. An optional hay/start fertilizer hopper (B) can be installed inside the hopper. There are feed-rate converters under the cover at the hopper end. Also, the feed-rate calibration test is carried out manually at the ends of the hoppers. The hopper is equipped with a roll-open tarpaulin cover (C) Hopper. Frame. Fig. 13 Fig. 14 3.4. Frame Introduction Demeter Multiseed combination placement drills are equipped with a separate frame of rectangular steel tube to which the coulter sections and the wheel assemblies as well the hitch bar have been attached. The frame which is separated from the hopper is strong but at the same time flexible enough to withstand all the load it is subjected to by the weight of the hopper and the coulters. At the same time the stress on the hopper transmitted by the coulters and the wheel assembly is less than if the hopper structure was self-supporting. The coulter section unit of the combination placement drill is grouped in half meter units of two fertilizer coulters, four seed coulters and two support wheels which are connected with each other by means of hydraulic cylinders. The rear wheel unit of the combination placement drill is grouped in units of two wheels which are connected with each other by means of hydraulic cylinders. This kind of system provides smooth compaction regardless of the variation in the soil contour. The system is divided into two hydraulic circuits to avoid inclination of the drill. The rear wheel hydraulics are not used for raising and lowering of the coulters and therefore it is not necessary to readjust them after the start-up. 14 3.5. Coulter section introduction The Demeter Multiseed is divided into 0.5 m coulter units (Fig. 15). Two fertilizer disc coulters (1) ( combi only) and four seed disc coulters (2) are mounted to each unit. The units can follow the ground contour by means of the traversing wheel pair (3) in front of each unit. The seed and fertilizer coulters are notched disc coulters. Diameter of the discs is 400mm. Each disc coulter pivots on the coulter frame with two ball bearings. The coulter (A) is mounted in to the frame (B) with three screws (Fig.16), which can also adjust the distance between the scraper and the disc. An elastic rubber plate (C) is located between the coulter and frame. The coulter has three mounting heights, which can be used according to conditions and coulter wear. Two discs and two coulters are mounted on each coulter frame (B). Each coulter frame (B) is attached to the coulter unit by an axle (5) (Fig. 15) and a rubber buffer (D) (Fig.16). The rubber buffer dampens intermittent shocks from the ground. The coulter units (Fig. 15) are mounted on the frame with two diagonal arms (4) (Fig. 15). Coulter unit Fig. 15 Coulter and the coulter frame. Fig. 16 15 3.6. Hydraulic system introduction Multiseed hydraulics has divided into two separate systems, rear wheel hydraulics andcoulter hydraulics. 3.6.1. Rear wheel hydraulics The rear carriage is divided into 0.5 m units. The arms of wheel units are mounted to the frame with flange bearings and hydraulic cylinders (3). The cylinders are interconnected with hydraulic lines in order that the rear carriage forms a closed hydraulic circuit. The hydraulic circuit is divided into a right and left sections using ball valves (1 and 2), which prevent the Multiseed from tilting. Specification fig. 17: 1. Rear wheel ball valve (right side section) 2. Rear wheel ball valve (left side section) 3. Wheel arm sylinder 4. Quick coupling to tractors single acting outlet. 5. Slave sylinder ( option ) 6. Slave sylinder ball valve Rear wheel hydraulics Fig. 17 3.6.2. Coulter hydraulics The coulter hydraulics is used by connecting hoses (1) and (2) to the double acting outlet of tractor. The coulter units are raised and lowered by hydraulic cylinders (4). At the same time the coulters are being raised, the rear harrow cylinders (5) will raise the rear harrow and the row marker cylinders (6) will raise the row markers depending selection of control box (Fig. 40, page 28 ). In addition to the coulter cylinders (4), the valve unit (3) is equipped with locking valves (7),pressure regulating valve (8), pressure accumulators (9), and a pressure gauge (10).Also, the row markers are equipped with magnetic valves (11) and flow control valves(12). When the coulters are lowered to the ground (Important! Multiseed must be in motion) and the cylinders (4) reach the adjusted pressure using the valve (8), the locking valves (7) will close and maintain the adjusted pressure in the hydraulic circuit. The pressure accumulators (9) function as shock absorbers in the circuit, for example, in cases where the coulters raise and lower due to stones. Lifting speed can be regulated whith valve (14). When the coulters are lowered, the rear harrow is also lowered. If required, the rear 16 harrow can also be locked up by closing the ball valve (13). The lift speed of the rear harrow can be adjusted with the flow control valve (15). The rear harrow can be left down by means of valve (16) even coulters have been raised. The row markers function by selecting either the right or left side row markers with magnetic valves (11) on the cabin control unit before lowering the coulters. Row markers can be selected to function also automatically. When the coulters are lowered, the selected row marker will also lower and after lifting the sections electric control swifts an other arm to lower. Coulter hydraulic. 1. Connecting hose 3.

Electric system introduction The Multiseed drills are equipped with tail lights and an electric area meter as well as with ready connection points for optional rowmarkers and alarm systems. The maximum permissible current feed to the fuse and connecting box of the combination placement drill is 12V / 25A. To ensure trouble-free operation, especially if any optional electric equipment is connected to the combination placement drill the output socket shall be connected according to the ISO standard directly to the battery using a cable of sufficient diameter via a fuse of 25A. The electric connection of the machine requires that the tractor is fitted with a socket for a 7-pin plug (C) (DIN ISO / 1724) (Fig. 19) for the tail lights and the electric connection of the area meter requires a socket for a 3-pin plug (B) (ISO/TR 12369: 1994(E) ) (Fig. 19).

In order to correctly hitch the Multiseed, the tractor should be equipped with a standard three-point hitch, one double and one single acting hydraulic outlet. In addition an other double acting hydraulic outlet is needed for an optional single toolbar and Multi Flex levelling board. One single acting outlet for optional drawbar adjusting ram. One 12 V, 3-pin EURO-connector and 7-pin outlet (minimum) is required for electrical functions and headlights, see also chapter 3.7. Introduction to electric system in page 18. 6.2. Hitching Multiseed to the tractor The drill can be mounted to the tractor in three different ways which are introduced in chapter 3.2 Hitch introduction on page 13. Make sure that securing pins are not damaged. Loosening machine on the road will cause severe damages. 6.3. Connecting hydraulics to the tractor Make sure that quick couplings are absolutely clean. Even small dirt will cause malfunction in valve unit. Also control that machine hoses as well as levellingboard hoses are connected as pairs into tractor outlets. 6.4. Connecting electronics to the tractor Make sure that sockets are connected correctly and 3-pin EURO-socket is protected by 25A fuse. 26 6.5. Adjustment of the rear wheel unit and coulter section position The Multiseed ( it’s frame) is brought to level position in the sowing / longitudinal direction by adjusting the length of the drawbar’s turnbuckle screw and the length of the rear wheel arm cylinders. When the fertilize coulters are towards the ground, the seed coulters should have 20 mm ground clearance (Fig. 38). The length of the rear wheel arm cylinders is regulated as follows (Fig.39): 1. Connect hose (4) (fig.17, page16) to the single-acting valve of tractor. 2. Open both ball valves (2) (Fig. 39). 3. Adjust frame heigth 670mm (Fig. 38) with tractor’s hydraulic outlet. 4. Close both ball valves (2) (Fig.39). 5. Disconnect the hose (4) frtom the tractor. If machine is tilting, it can be swing to the other side by climbing onto the ladder of platform. Make sure that frame is paraller with the ground. The correct frame height can be verified by checking angle between coulter frame and diagonal arms during the operation. The angle should be 45°. Final check of the correct height is done after required seeding depth has achived on the field. Note! Machine must be on the firm levelled ground. Adjustment of drill position. Fig. 38 Rear wheel units locking valves and connecting hose. 27 Fig. 39 6.6. Area meter / control box The drill is equipped with an electronic area meter. Fit the display of the area meter in the tractor in a suitable place, where it is easy to monitor. If the drill is equipped with the rowmarkers, position the control box in a place in which it does not hamper the use of the switches. When LH-1600 is used, area metering is not connected. The area meter is operational if the power supply plug (A) (fig. 19, page 18) is connected to the tractor and the area meter connector (C) (fig. 19, page 18) is connected to the cable leading to the drill. When the green LED (F) in the area meter illuminates, the meter is ready for operation. The meter is reset by button A. Functions of the control box: A. Reset of the area meter B. Automatics and independent control of the rowmarkers C. Repeated operation of the rowmarkers and reset of the alarm D. Control of rear harrow E. Signal light of the alarm F. Power on light G. Area meter. The red light (E) is the warning light for the alarm system (optional equipment) and the switches (B and C) (2 pcs) are the control switches for the rowmarkers and rear harrow. Fig.40 The reading accuracy of the meter is 1/100 ha. For example, a reading of 100 is equal to one hectare. NOTE! Protect against moisture Switch B In position 1 the rowmarkers are not operational. In position 2 the automatic control is on. In position 3 independent control of the rowmarkers (optional equipment). Switch C In position 1 the functions of switch B are operational. In position 2 the marker on one side is lowered repeatedly, switch B must be in position 2. In position 3 reset of the alarm, the switch returns to position 1. Fig. 41 Switch D In position 1 the rear harrow operates simultaneously with the coulters. In position 2 the rear harrow is not operational and can be left either in the upper or the lower position. 28 6.7. Basic settings for hydraulic system All basic settings are made after connecting the Multiseed to the tractor. Multiseed hydraulic system is working optimally with oil flow from 40 – 50 l/min. Since modern tractors have usually much higher, adjustable oil flow it is recommended to limit oil flow in tractors outlet. In this case consult your tractor dealer. While adjusting hydraulics run engine accordingly to drilling speed. Settings are to be performed on a level surface. 6.7.1. Setting row marker speed The desired operating speed of the row markers can be set with the flow regulating valve (1) and (2) of valve unit. The valve (1) is for lifting speed and the valve (2) is for lowering speed. Speeds are decreasing when turning spools clockwise with 1/6¨ (4mm) hexagonal wrench. The valve can also be turned until completely closed, thus inhibiting any movement of the row markers. Keep spool still while locking it with nut (3). Lifting speed adjusting. Lowering speed adjusting. Fig. 42 Fig. 43 6.7.2 Setting the coulter pressure Coulter pressure is set using the pressure regulating valve (5) (Fig.44) of the valve unit. The pressure regulating valve has an adjustment range of 30-90 bar. When setting the pressure control, raise the coulters and close the coulter section ball valve (3) (fig. 39), preventing movement of the coulter section but allowing for the Fig.44 adjustment of pressure. The coulters are locked up in order to avoid blocking. The pressure will increase when turning spool handknob clockwise . Keep spool still while locking it with nut (3). 29 Important! The pressure regulating valve is factory pre-set for 4050 bar, which is sufficient for holding the coulters at the desired seeding depth under normal conditions even when the seed tanks are nearly empty. Due to the high operating pressures, it is advisable to keep the tanks as full as possible in order that the Multiseed’s weight is sufficient enough to hold the coulters in the ground. On loose soil, such as when seeding after being tilled, the compacting effect of the front wheels can be enhanced by increasing the pressure of the coulter section. If the soil requires a great deal of compacting, use of the optional intermediate press wheels and tractor tires equalling the width of the Multiseed are recommended. Important! When using high pressures, the Multiseed’s overall mass will not necessarily be sufficient, and the equipment will rise. 6.7.3 Setting the coulter lowering speed The desired lowering speed of the coulter sections can be set by using the flow regulating valve bold (6) of the valve unit. Speed is decreasing when turning spool clockwise with 1/4¨ (6 mm) hexagonal wrench. Lifting speed is not to be adjusted. Keep spool still while locking it with nut (3). 6.7.4. Setting the rear harrow lift speed Setting the coulter lowering Fig. 45 speed. The desired lift speed of the rear harrow lifting can be set by using the flow regulating valve (4) of the valve unit.. Speed is decreasing when turning spool clockwise with 1/6¨(4 mm) hexagonal wrench. Lowering speed is not to be adjusted. Keep spool still while locking it with nut (3). Setting the rear harrow lift speed. 30 Fig. 46 6.8. Filling the hoppers There are different ways to fill the hoppers. The conditions and possibilities on the farm largely determine the method used. Before filling tanks, ensure that: 1. the bottom flaps are closed and the shutter is in the correct position (Fig. 49 and 50). Fig.47 Fig.48 2. the tank partition is in the desired position. 6.8.1. Intermediate wall adjustment The intermediate wall between the fertilizer and seed units has easy non-tool requiring adjustment. The locking pin can be turned open figure 47 and then wall is free to move into desired position. The volumes with different partitions are shown in section Enclosures. 6.8.2. Filling from large bags (e.g. 800 kg) If a suitable crane or lifting device is available, the big bags can be emptied directly into the hoppers of the drill. If this method is applied, it is absolutely prohibited to go under the hanging bag. A safer method is first to empty the big bags onto the trailer and then to apply filling methods adapted for bulk seed and fertilizer. 6.8.3. Filling with bulk seed and fertilizer E.g.a high tipping trailer with an auger is suitable for handling bulk seed and fertilizer. When filling the hoppers, make sure that no foreign bodies, such as pieces of paper or plastic bags, enter the hopper. Such items could block the feeder units. Always keep the fertilizer sieve in place, especially if the fertilizer is lumpy or of inferior quality. 6.9. Feeding systems and their adjustment Fig.49 and 50 The feed rates for seed and fertilizer are independently adjusted by changing the rotation speed of the feed roller, the whole working width of the drill is not used, or if only every second seed coulter is in use if extremely low seeding rate is desired. Both the fertilizer and the seed units have a steplessly adjustable rotation speed converter. In addition, the seed unit is equipped with a cassette. Depending on the seed size, three different basic setting ranges can be selected. The feeder cases of both the seed and fertilizer units have shutters and bottom flaps. The shutters regulate the flow of fertilizer and seed to the feed rollers. If needed, some 31 of the shutters can be completely closed, if, for instance, the whole working width of the drill is not used, or if only every second seed coulter is in use. The correct setting of the bottom flaps is important, as their distance to the feed roller influences the accuracy of the feeding. The bottom flaps are spring-loaded to prevent damage in case a foreign object goes in to the feeding unit. The settings for the feeder mechanisms are given by the calibration chart fixed on the inside of the cover on the right-hand side, and in this manual on page 36. 6.9.1. Feed rate setting for fertilizer (combi) The fertilizer feed rate is adjusted with the gearbox on the left-hand side of the drill. The indicative feed rates for normal granulated NPK fertilizer and urea are given in the calibration chart. As the feed rates may vary considerably between different fertilizer types and production lots, it is important to always perform a calibration before commencing sowing. Adjust the fertilizer unit shutters (E) and the bottom flaps (F) as follows: Shutters, position 3 3 Urea Granulated fertilizers Shutter and the bottom flap lever. A Bottom flaps, notch on arch segment 3 3 Location of the ferti- B lizer bottom flap lever. Fertilizer feeding gearbox. C Fig. 49 6.9.2. Feed rate settings for seed The seed feed rate is adjusted by cassette and the rotation speed converter at the right-hand side end of the drill. The calibration test chart includes the cassette positions and indicative settings for the following seed: wheat, rye, oats, barley, peas,rape, clover and timothy. Because the properties between the different seed lots may vary considerably, it is always important to perform a calibration test before commencing the sowing. 32 The seed unit shutters (E) and bottom flaps (F) should be set as follows: (see Fig 50) Shutters, notch 2 2 2 Cereals Small seed Peas Shutter and the bottom flap lever. A Bottom flaps, notch on arch segment 2 2 4 Location of the seed bottom flap lever. B Seed feeding gearbox. C Fig. 50 6.10. Calibration test It always pays to check the feed rates for both fertilizer and seed by performing a calibration test. Fill the hoppers with seed and fertilizer. Lower the coulter section to approximately 5 cm from ground. 6.10.1 Calibration test for seed A) Check the settings for the shutters, bottom flaps and cassette in the calibration test chart (Fig. 54, page 36). Turn the rotation speed converter lever to match the value given by the calibration chart. Carefully tighten the locking screw on the lever. B) Shift the calibration trays to the calibration test position by pulling the locking knob (G) and at the same time turning the shaft clockwise with the calibration test crank (H) until the system locks in the lower hole. On the Multiseed the locking is at the left-hand side end. Push the calibration trays (I) under the feeder cases, the longer one first. C) Remove the linchpins (2 pcs.) of the cassette and pull out the cassette (by about 20 mm) to a position where it can be locked in the outer hole on the up most shaft (J) using one of the linchpins. Fit the calibration cranck to the under most bushing (K) (Fig. 52) of the cassette and turn it in the direction of the arrow until the seed feeder units start to feed. After that, pull out and empty the calibration trays. D) Push the test run pans back under the feed hoppers. Turn the cassette’s lower turning hole in the direction of the arrow of the cassette in the direction of the arrow a number of turns which corresponds to sowing an area of one are. 33 Multiseed 3000 (3.0m) Multiseed 4000 (4.0m) 9 3/4 turns 7 1/4 turns E) Remove the calibration trays and weigh the gathered seed. Multiply the measured weight by 100 to get the quantity of seed for 1 hectare. If the result differs from the desired value, shift the adjustment lever along the scale as necessary. Repeat the calibration test after the readjustment. F) Upon completion of the calibration test, shift the calibration trays forward to the sowing position. It is essential not to forget to push the cassette inwards so much that it can be locked to the shaft by both its upmost and undermost bushings. 6.10.2. Calibration test for seed by driving 1. Check that the settings for the shutters, bottom flaps and cassette are correct for the seed used. Turn the rotation speed converter lever to match the value given by the calibration chart. 2. Fill the seed hopper. 3. Push the calibration trays under the feeder cases. Drive with the drill in the sowing position until the seed feeder units start to feed. Pull out the tray and empty it. 4. Put the calibration trays back to the calibration test position. Drive the machine in the sowing position over a distance of 33.3 m MS 3000 and 25.0 m MS 4000. 5. Remove the calibration trays and weigh the seed collected in them. Multiply the quantity by 100 to get the quantity for 1 hectare. If the result differs from the desired value, shift the adjustment lever along the scale as necessary. The calibration test should be repeated after the readjustment. Shifting the calibration Fig. 51 trays to the test position. Locking of the cassette in the outer hole Fig. 52 for the calibration test with seed. Insert the crank to under most bushing (K) 34 The calibration test carried out by driving is more accurate because it also takes into account variations in the feed rate caused by the vibration of the machine or slipping of the wheels. Never use the area meter for calibration purposes. Insufficient pressure in the support wheel tyre affects the feed rate, so the pressure must be checked regularly. The correct tyre pressure for MS 3000 and MS 4000 drills is 136 kPa (1.4 bar). 6.10.3. Calibration test for fertilizer (combi) A) Check that the settings for shutters and bottom flaps are the correct. Turn the rotation speed converter lever to match the set value in the calibration chart (Fig.54, page 36). B) Shift the calibration trays to the calibration test position by pulling back the locking knob (G) and at the same time turning the shaft (H) clockwise until the system locks in the lower hole. Push back the calibration trays under the fertilizer feeder cases (the longer one first). C) Remove the cassette and fit the calibration test crank to the under most shaft. D) Turn the crank in the direction of the arrow the number of turns which corresponds to sowing an area of one are, which is the same as that required for the seed unit ( MS 3000 9 3/4 and MS 4000 7 1/4 turns). E) Weigh the quantity of fertilizer gathered on the tray and multiply it by 100 to get the required quantity of fertilizer for 1 hectare. If it differs from the desired quantity, the adjustment lever should be shifted along the scale as necessary Calibration test for fertilizer. and the test should be repeated. Finally, in any case do not forget to attach the cassette in the sowing position. Fig. 53 6.10.4. Calibration test for fertilizer by driving The calibration test for the fertilizer unit by driving is carried out in the same way as the calibration test for the seed unit in Section 6.10.2. Check on the calibration test chart that the settings match with the set values for the fertilizer. 35 6.8. Calibration chart Fig. 47 36 6.12. Seeding depth adjustment Connecting plate (Fig. 59 page 39) could be mounted into a fixed or floating position. For drilling in heavy conditions ( e.g. direct drilling) the drive wheel arm should be floating in order to ensure continue drive of feeding system. 6.12.1. Coulter frame depth adjustment Setting the fertilizer and seed depths occurs simultaneously. The forecarriage height is adjusted by turning the appropriate screw (A). Each coulter unit has its own adjustment screw and adjustment scale. Each turn of the crank equals an approximately 10 mm adjustment in the coulters. The adjustment scale reading Fig. 55 not indicate the seed or fertilizer depht. Using the scales, it is easier to set the coulters at same height. Setting of the dirve unit differs sligthly, due to the larger diameter of the tractor pattern tyre. The Drive wheels should be set 1/4 - 1/2 scale unit deeper. The fertilizer coulters are factory-installed 20 mm lower than the seed coulters. The coulter have three different mounting heights, which, if necessary, can be changed according to conditions and hopper wear. Important! More on coulter setting in section 8.7 “Setting of coulters”. 6.12.2. Individual coulter depth adjustment Coulters have three height positions. Coulters are factory-installed in the middle position. When operating in very light soils coulters can be mounted in to highest position in order to ensure better disc rotation. The lowest position is used when coulters are worn or drilling in hard soils. Fig. 56 37 6.13. Field settings 6.13.1. Setting seeding depth If needed the seeding depth can be re-adjusted according section 6.12. Seeding depth Adjustment 6.13.2. Setting of the rear harrow The rear harrow cylinders are connected to the same hydraulic circuit as serves the coulter section lift. The rear harrow rises when the coulters are raised. When the coulters are lowered, the rear harrow will lower under its own weight. Its lift speed can be set using flow control valve (4) (fig.46). The rear harrow can be locked in its upright position by closing check valve (7) (fig.46). The rear harrow tine angle can be adjusted by changing the point of the mounting pin (A) (fig. 57). The rear harrow is also equipped with an electric valve, with which it can be locked in its operating position when the coulters are raised (a semi-lift, such as when making a turn without backing up). Fig. 57 The rear harrow can also be raised by cutting the power to the electric valve and raising the harrow with the hydraulics. When the electric valve is turned off, the harrow will rise and lower with the coulters. The semi-lift function is controlled using the control unit – see section 6.6 Area meter / control box. 38 6.13.3. Setting the row marker pin The row marker pin is set either to the rear of the tractor wheel or the center of the tractor. The row marker pin is considered centered when the distance (x) between the Multiseed frame and pin is 1.5 m (Multiseed 3000) or 2 m (Multiseed 4000). The pin can be moved laterally by loosening the mounting bolts. 6.13.4. Checking the correct coulter pressure Fig. 58 While seeding pay particular attention to coulter pressure corresponding to the soil condition. The coulter pressure must overcome penetration resistance of the soil. The correct pressure can be verify as follows: 1. Front wheels mounted floating in to the wheel arms ( see position A, fig. 59). The adjustment tube must have continuos contact towards wheelarm while seeding. 2. Front wheels mounted fixed in to the wheel arms (see position B, fig. 59) .The front wheel must stay firmly in the ground while seeding If these terms does not come true the coulter pressure must be increased according section 6.7.2. Setting the pressure control. Fig. 59 6.14. Inspection of Multiseed function When seeding, regularly inspect: - the seeding depth - that all coulters are open Any blocking of the fertilizer coulters is best inspected through the feed chamber window. Any blocking of the seed coulters can best be located by inspecting the top of the cone rail. 39 Placing tape on the fertilizer unit’s feed axle makes it easy to see when the feed is running or not. Tank discharge and feed rates can be tracked using an area meter. If, for example, 500 kg/ha is to be fertilized and the Multiseed is loaded with two big bags (1200 kg), over 2 ha can be seeded on one full tank. Blocking of the coulters can best be avoid ed by lowering and raising the Multiseed during forward motion. The Multiseed should not be reversed while the coulters are still in the ground. Do not go under an unsupported Multiseed ! 6.15. Hopper discharge Discharging the tanks can be performed using the following methods: 1. Small seed and/or fertilizer quantities can be emptied into the calibration trays. The trays are placed under the feed chambers and the bottom flaps are opened. 2. Both seed and fertilizer can be discharged onto a tarpaulin placed under the coulters. Raise the Multiseed completely by increasing the oil level of the rear carriage. Place a tarpaulin under the coulters and lower them. Open the bottom flaps. It is necessary to raise the Multiseed so that the seed and fertilizer hoses are straight. 3. Using a high-power farm or industrial vacuum, the hoppers can be emptied quickly.When the tanks are empty, cycle the seeder a few times with the test run crank, in order to also empty the feeding system. Clean the seeder thoroughly at the end of each season. 40 7. Guidlines and methods of use 7.1 Guidlines for use Always lower and raise the Multiseed when moving forward. In places where this is not possible, such as in field corners, take extra care in order to avoid blocking the coulters. Seeding can be performed by driving around the section or by driving 3-4 times around the perimeter of the field and then making straight passes back and forth up the field. Both methods require driving over already seeded soil. If this is to be avoided, the perimeter can be seeded last. Begin seeding directly from the side of the field and measure/mark the width of the perimeter on the field. The perimeter can also be estimated as approximately 3-4 Multiseed widths, so that it will be easy to turn the Multiseed. Seeding the perimeters last allows for a clean and untracked field. The recommended seeding speed is 6-15 km/h, depending, to a great extent, on the seeding conditions. The operator is responsible for making sure that there are no personnel on the Multiseed or within its 3,0 m danger zone while in operation. Avoid making sharp turns while the coulters are in the ground. When reversing, always check that there is enough ground clearance. Remember to raise the rear harrow before reversing. 41 7.2. Seeding methods 7.2.1. Traditional The great advantage of the Multiseed over traditional seeder/combi machines is that tilling to the seeding depth is not necessary. The soil can be tilled extremely deep, as the disc coulters sink easily into moist soil. Tractor fuel savings are also achieved in comparison to performing a deep tillage. When using the Multiseed, it is recommended to till 1-2 cm lower than the seeding depth. If the harrow depth is the same as the seeding depth with the harrow going even deeper in certain places, then the Multiseed will seed loose soil. This is due to the fact that the forecarriage limits the seeding depth and the coulters will not follow the tillage base as traditional seeding machines generally do. The amount of tilling necessary can be reduced by seeding directly on a newly ploughed field. When seeding on newly ploughed soil, the Multi Flex levelling board (optional) is recommended. 7.2.2. Reduced tillage Reduced tillage is a practical method primarily for use on clay or silt. By using the reduced tillage method, it is possible to both save on tillage costs and improve the soil structure. It is especially important to run wide tires on the tractor and other machinery in order to avoid excessive soil compaction. For example, deep cultivated soil is extremely loose; this may cause problems when seeding. Increasing the coulter section pressure can improve the forecarriage’s compacting effect. For these kinds of conditions, use of the inter wheel packer (optional) is highly recommended (requiring wider tractor tires, equalling the width of the Multiseed). Thus, the entire seeded area is compacted and seeding performance is improved. On deep cultivated soil it may be necessary to shift the coulters to a higher mount in order for the discs to turn more easily, see section 6.12.2 Individual coulter depth. The need for this also depends on the seeding depth. When seeding after perfoming a reduced tillage, it is recommended to use the leveling board to break clods and level out the soil surface. If there is a great deal of straw on the soil, the leveling board may catch an excess of straw and earth, so constant checking of the leveling board and correct setting of the tine angle are important. If there is an excessive amount of straw present, the levelling board can be locked up. Seeding straigt on ploughed field can be done by using Multi Flex levelling board. 42 7.2.3. Direct seeding Direct seeding is possible with the Multiseed under good conditions. If there is excess straw on the field, it should be removed. Depending on the seeding depth, it may also be necessary to mount the coulters at a higher level. When direct seeding, the leveling board and rear harrow can be locked up. Increased coulter pressure may also be required. See section 6.7.2 Setting the suitable coulter pressure. On very hard soils and under difficult conditions, direct seeding will probably not work and the soil may have to be stubble cultivated. 7.3. Seeding low rates When drilling very low amount of seed (e.g. rape) it is recommend to use only every other seed outlets. This measure gives higher seed distance accuracy in the row. Diagram below is showing when every other outlet is recommended to close. For example when required seed has kernel weight ( the weight of 1000 pcs of seed in grams ) 6, recommended lowest seeding rate ( kg/ha) with all feeding outlets is 3,6 kg/ha. Minimum seeding rate 4 Min. seeding rate kg / ha 3,5 3 Min. seeding rate kg/ha with all outlets 2,5 2 Min. seeding rate kg/ha with every other outlets 1,5 1 0,5 0 1 2 3 4 5 6 Kernel weight gr/1000pcs Fig. 60 43 8. Maintenance Well-maintained equipment ensures problem-free operation during the busy sowing season. Maintenance and lubrication intervals are listed in table 8.2 (normal use); shorter intervals will be required for heavier use. Multiseed has large number of sealed, self-lubricating ball bearings, thus reducing the need for additional lubrication. 8.1. Maintenance guidlines 1. Check the tightness of all screws and nuts (according to table 1) before to beginning work. New equipment in particular requires the checking of screw and nut tightness after only a few operational hours. 2. Tire pressure must be checked according to technical specifications. 3. Rim screw tension must be regularly checked (see section 2.4 Operating instructions for rims). 4. All bearings must be checked and lubricated regularly. All chains must be checked, tensioned, and lubricated regularly. Lubrication points and requirements are listed in more detail in the maintenance chart (page 45). Only high-grade lubricants and oils are to be used for lubrication in strict observance of their recommendations and specifications. 5. A thorough cleaning of the Multiseed of all loose dirt and stuck soil after each use will increase its performance and operating life. Cleaning can be performed with a high-pressure spray, taking special attention to avoid the spray jet on electrical equipment and bearings. 6. In order to prevent rusting on susceptible parts, an application of oil immediately after cleaning is recommended. A dry run should also be made, in order to ensure the circulation of lubricants and removal of water. 7. Any worn paint on metal parts should be touched up. 8. While performing maintenance on the Multiseed, ensure that the lubricants and other chemicals being used are not released into the environment. Important ! The seed feed system cassette is maintenance-free. 44 8.2. Lubrication chart Greasing points: Number of nipples Greasing 3.0m 4.0m Pos. Interval/hrs Fertilizer tank: 1.

The grease gun nozzle and lubrication nipples must be clean. 1 to 2 squeezes is generally adequate. F M Fig. 61 Excess lubricant is to be wiped off. Clogged or otherwise defective lubrication ports must be replaced with new. The Multiseed roller chains are to be lubricated with pure mineral oil (viscosity SAE20) At the end of the operational season, the chains must be completely cleaned with gasoline or petroleum. If the chains are then dipped completely in melted graphite petroleum jelly, they will not require lubrication during the operational season. 45 8.3. Tightening torques Unless specified otherwise elsewhere, use the following tightening torque values for the screws and bolts. The tightening torque depends on the diameter and hardness of the screw (the hardness is indicated on the screw head). Tightening torque Nm ( = 0.1 kpm ) Diameter mm 5 mm 6 mm 8 mm 10 mm 12 mm 16 mm 20 mm 24 mm 30 mm Hardness 8.8 6 11 28 55 95 235 475 825 1630 Hardness 10.9 9 17 40 80 140 350 675 1170 2320 8.4. Tyre Pressure Forecarriage: 117 kPa (1.2 bar) Rear carriage: 136 kPa (1.4 bar) Interwheel packer: 136 kPa (1.4 bar) 8.5. Locking coulter section up during maintenance On the rear harrow there is a bar locked by a cotter pin, with which the coulters must be locked up. Unlock the bar and insert it through the loops on the coulter section.The ball valve (3) (Fig. 39, page 27) of coulter section hydraulics must be also closed. The rear carriage can be locked up by placing maintenance braces on the outermost wheel pair rams. The maintenance braces are stored on the frame with rubber cords, next to the rear carriage hydraulic lines. Remember to remove the bar from the coulter section and the maintenance braces from the rams after completing service/cleaning. Reattach the bar to the rear harrow. This is important, as the bar also serves as the rear harrow weight. Important! See also section 2.3 Safety instruction for Multiseed. 46 8.6. Fertilizer and seed coulters The fertilizer and seed coulters are disc coulters. Disc (1) runs on 2 self-lubricating ball bearings, thus eliminating the need for additional lubrication. The coulter (2) with scraper is mounted on the coulter frame (3) with 3 hex screws (4). There is a rubber plate (5) between the coulter (2) and frame (3). See also figure 16 in page 15. Fig. 62 8.7. Setting of coulters The distance of the scraper (2) from the disc (1) is set using screws (4). The distance is correct when the scraper lightly touches the disc, but does not impede its rotation. The distance must be reset if there is anything between the scraper and disc, which impedes the rotation of the disc. The distance between the coulter and disc should be equal from the top of the scraper, or slightly closer from the bottom than the top. The coulter mounting screws have 3 different mounting heights. The coulter position in relation to the disc can be set according to conditions or coulter wear. In most cases, the disc is approx. 10 mm deeper than the coulter. When direct seeding and on stubble cultivated soil, the coulter can be mounted at a lower level than for a normal seedbed preparation. The optional slave cylinder (522000133) eases the performance of maintenance tasks. See also chapter 9.6. in page 59. 47 8.8.

Rotation speed converter The rotation speed converters are maintenance-free. However, the oil should be changed before every season or every 500 hours of operation . The oil is drained through the opening (E). Fill the converter with new SAE 90 gear oil to the level of the filling opening (F). The filling capacity is approximately 0.5 litres. If the rotation speed converter requires repair, consult your dealer or the manufacturer. Fig. 63 50 9. Optional equipment 9.1. Independent control of the rowmarkers A separate control valve, which is available as an optional equipment, can be used for repeated raising and lowering of the rowmarker, which was actuated last without having to lift the coulters and thus interrupt the sowing, as may be necessary, for example, when passing by an obstruction. The order number for control is 522 00 140. See also chapter 6.6. Area meter / control box. 9.2. Alarm sets As optional equipment, it is possible to install in connection with the rowmarkers a rotation guard for the feeder shaft 521400136 (at maximum 2 pcs) and a hopper level guard 521400137. The number of level guard sets is not restricted. Fig. 64 9.2.1. Rotation guard set for the feeder shaft The rotation guard activates a light and sound alarm in the control box in the tractor cabin if the feeder shaft stops during driving. If the rotation guard has been installed on two shafts, the device does not indicate which one of the shafts has triggered the alarm, but this has to verified in the machine by checking. The alarm is reset with the switch (C) on the control box by turning it clockwise. See also chapter 6.6. Area meter / control box. 9.2.2. Hopper level guard set The hopper level guard activates a light and sound alarm in the control box in connection with running out of fertilzer or seed in the course of driving. The alarm is reset with the switch (C) on the control box by turning it clockwise. See also chapter 6.6. Area meter / control box. 51 9.3. Hydraulic levelling board The Multiseed can be equipped with a single toolbar or a double toolbar levelling board. The equipment levels field surface, tills soil, and breaks clods. 9.3.1. The single toolbar levelling board This optional equipment has only one hydraulically operated toolbar and only one type of tine. Toolbar lifting cylinder is connected into the Multiseed’s coulter lifting hydraulic system. So toolbar is lifting and lowering towards with coulter sections. The working angle of tines are adjusted by tractor’s double acting hydraulic outlet. The basic height of toolbar can be adjusted by chancing the upper fitting point (A) of lifting cylinder. The order number for levelling board is: MS 3000: 522000101 and MS 4000: 522100101. Fig. 65 9.3.2. Multi Flex levelling board The Multi Flex levelling board has two toolbars for more effective seedbed preparation. The optimum working angle of tines is 45° against ground level. Fig. 66 Fig. 67 Tines: Multi Flex levellingboard has two tine alternatives. The Flex-tine (up right) has 80 mm wide, straight plate for ploughed and light stubble cultivated soils. The harrow tine (down right) has narrow, bent cultivator tip for heavier soils. Different type of tines can be mounted on Multi Flex, e.g. harrow tine in the front for 52 soil preparation and Flex-tine in the rear for levelling. Both tines are to be ordered separately, Flex-tine nr.: 41652054501 and harrow tine: 41652162601. Normally 10 pcs / metre (working width) of tines are used with Multi Flex Adjustments: Factory assembled Multi Flex levellingboard has parallel angles of the tines (pins in position A-1, fig 68). However if needed, tine angles between front and rear toolbars can be changed. If more effective tillage is needed, the front tines can be adjusted to bigger angle by changing pins to position A-2. If the rear tines are desired to be more aggressive, then pins can be changed to position B-1. Fig. 68 Maintenance: Multi Flex has only two greasing point in the both end of cylinder. Greasing interval for these points is 40 hrs. The order nr. for complete carrier frames are: MS 3000: 522000135 and 522100135 53 MS 4000: 9.4. Grass seed / start fertilizer hopper 9.4.1. The feeding system and it’s setting The feed rates for start fertilizer or grass seed are adjusted by changing the rotation speed of the feed rollers. The additional hopper is equipped with a stepless gearbox (Fig. 70). The feeder cases of the additional hopper are equipped with shutters and bottom flaps. The shutters restrict the flow of the start fertilizer or the grass seed to the feed rollers. If necessary part of the shutters can be closed, if, for example, the working width of the drill is not utilized in full. The bottom flaps are spring-loaded to prevent damage should some foreign body stick between them and the feed roller. 9.4.2. Setting of the feed rate Adjust the shutters (E) and the bottom flaps (F) of the additional hopper in the following way: Granular start fertilizer Small seed Shutters, position 2 2 Bottom flaps, notch on arch segment 2 2 Shutters and the bottom flaps of the additional hopper. The feed rate of the start fertilizer / grass seed is adjusted with the rotation speed converter at the right-hand end of the drill. Refer to the calibration chart for the indicative settings for granular start fertilizer, timothy, clover and grass seed. Fig. 69 Because the properties of the different fertilizer / grass seed lots may vary considerably, it is always important to perform a calibration test before commencing the sowing. 54 9.4.3. Calibration test by turning with crank It is always pays to check the feed rate both for fertilizer and seed by performing a calibration test. Fill the hoppers with fertilizer or seed. Lower the coulters 5 cm from the ground and check that Multiseed is standing level. A) Check the calibration test chart for the correct settings for the shutters and bottom flaps for the used seed. Turn the gearbox converter lever to match the value given by the calibration chart. Carefully tighten the locking screw on the lever. Lower the drill to the sowing position. Set the gearbox for the fertilizer feeder to position 0. B) The procedure of the calibration test for grass seed is similar to start fertilizer. Only difference is the placement of calibration trays (fig. 72). 1. Remove cone rails (1) down by opening nuts (2). 2.) Place calibration trays on the supports. The gearbox for grass seed / Fig. 70 C) The cassette is removed and the calibration start fertilizer hopper. crank is fitted to the undermost shaft (Fig. 53) and turned in the direction of the arrow until the seed feeder units start to feed. After that, pull out and empty the calibration trays. D) Push back the calibration trays under the feeder cases. Turn the lower shaft (Fig.53) in the direction of the arrow the number of turns which corresponds to sowing an area of Fig. 71 Fig. 72 one are (1/100 ha) 9 3/4 turns for MS 3000 (3.0m) and 7 1/3 turns for MS 4000. This value is multiplied by100 to get the required quantity for 1 hectare. E) Remove the calibration trays and weigh the collected seed. Multiply the quantity by 100 to get the quantity for 1 hectare. If the result differs from the desired value, shift the adjustment lever along the scale as necessary. Repeat the calibration test after the readjustment. After calibration test is finalised, fit the cone rails and casette back. 55 9.4.4. Calibration test by driving 1. Check that the settings for the shutters, bottom flaps and cassette are correct for the seed used. Turn the rotation speed converter lever to match the value given by the calibration chart. 2. Fill the seed hopper. 3. Push the calibration trays under the feeder cases. Drive with the drill in the sowing position until the seed feeder units start to feed. Pull out the tray and empty it. 4. Put the calibration trays back to the calibration test position. Drive with the machine in the sowing position over a distance of 33.3 m (3.0 m drill) and of 25 m (4.0 m). 5. Remove the calibration trays and weigh the seed collected in them. Multiply the quantity by 100 to get the quantity for 1 hectare. If the result differs from the desired value, shift the adjustment lever along the scale as necessary. The calibration test should be repeated after the readjustment. The calibration test carried out by driving is more accurate because it also takes into account variations in the feed rate caused by the vibration of the machine or slipping of the wheels. Never use the area meter for calibration purposes. The tyre pressure affects the feed rate, so it must be checked regularly. The correct tyre pressure for the Multiseed 136 kPa (1.4 bar) The order number for the additional hopper is: (MS 3000) 522 000 138 (MS 4000) 522 100 138 56 9.4.5. Calibration chart Calibration chart of the additional hopper. 57 Chart 2 9.5. Electric remote control of the feed rate 9.5.1. User instructions The feed rate can be adjusted steplessly from the cabin during driving by using the remote control. The current speed converter feed rate reading is shown by the display on the control box. It is possible to install the electric remote control of feed rate on the speed converter for either the fertilizer or the seed feed. The calibration test of the drill is carried out in a normal manner, the only difference is that the speed converter adjustment is carried out by pushing the buttons in the cotrol box of the remote control. Control box of the remote control. Fig. 73 Actuator. Fig.74 If you want to alter the feed rate during sowing, verify the settings for each desired rate by means of a calibration test. Write down on a piece of paper the display readings during the calibration test, so you can use this information for setting during the sowing. To retrieve the indicative values based on the calibration chart on the display, push either the ‘+’ or ‘-’ button. Pushing the ‘+’ button increases the feed rate. Pushing the ‘-’ button decreases the feed rate. Note! The reading on the control box display is the same as the one indicated by the transmission adjustment lever. So the reading on the display does not directly indicate the kilos or changes in the fertilizer feed rate in percent. The order number for the feed remote control is 522 000 122. 58 9.6. Slave cylinder The slave cylinder will increase easily ground clearance when servicing coulter sections. It increases ground clearance 155 mm (MS 3000) and 120 mm (MS 4000).

The stone protector kit can be assembled afterwards. The order numbers are: MS 3000: 522000137 and MS 4000: 522100137. 60 9.10. Seed dressing applicator With seed dressing applicator seed can be mixed together with a small quantity of dustlike materials. The device has a small hopper to be assembled inside seed hopper just above agitator shaft. 9.10.1. User instructions The filling of the seed dressing applicator is best carried out with the wings of the agitator shaft in an upright position. The seed dressing must be spread evenly in the hopper. The feed rate will remain accurately constant, if the surface of the seed dressing is kept above the agitator shaft. If the surface of the seed dressing is below the agitator shaft level, the quantity can fall short of the set value. The feed rate of the seed dressing is adjusted by changing the distance of the revoving bar from the hub of the freewheel clutch, refer to Fig. 80. Before the seedeng, keep rotating the machine until the seed falling on the ground is covered by dressing. The calibration test can be performed after this. The calibration test should be repeated after one hour of sowing. If you want to disable the seed dressing applicator, shift the revolving bar to position (0). For this purpose, loosen the screw (G) shown in Fig. 80 in position (A) and tighten it in position (0). The hopper volumes are: MS 3000: 8,5 ltr and MS 4000: 12 ltr Order nrs for applicators are: MS 3000: 522000123 and MS 4000: 522100123 Seed dressing feed adjustment. 61 Fig. 80 9.10.2. Setting of the seed dressing feed rate The feed rate is adjusted stepwise at the end of the rewolving bar (positions o,a,b and c) and steplessly at the freewheel clutch lever (scale from zero to eight). As the seed feed rate of Juko drills is adjusted by changing the speed of the feeder shaft, the feed rate of the seed dressing remains constant (g/100kg of grain) regardless of any changes in the rotation convertter setting with the same cultivar.
