Performance Tips New Holland Sickle Mower Conditioners NEW HOLLAND PERFORMANCE TIPS Introduction Thank you for taking the time to participate in this New Holland Haybine® mower conditioner customer clinic. Our goal is to heighten your awareness of product features and function, as well as certain machine adjustments and maintenance procedures that will enhance the performance and prolong the life of your mower conditioner. We have included information in these Performance Tips that will be helpful in operating and maintaining your New Holland Haybine. Your Operator's Manual will include most of this information, and should always be your main resource for answers to your machine operation questions. If your mower conditioner is operated or maintained by more than one person, be sure to share helpful hints in this guide with all operators to keep your machine working at top efficiency. At New Holland, we want to see you achieve a level of performance and reliability that exceeds your expectations, and confirms the belief that you have purchased the best hay equipment available. 2 CONTENTS Safety ............................................................ 3 Service Inspections................................... 4-5 Operation................................................. 6-12 Troubleshooting .................................... 13-18 Maintenance ............................................... 19 SAFETY A careful operator is the best operator. Most accidents can be avoided by observing certain precautions. To help prevent accidents, read the following precautions and the full list of precautionary statements in the Operator's Manuals. General Safety Rules • Read the Operator's Manual thoroughly before starting, operating, servicing or carrying out any other operation on the machine. The time invested in reviewing the manual will pay off in terms of time saved later. • Read all the safety decals on the machine and follow the instructions. Immediately replace any decals that are missing or damaged. • The mower conditioner should be operated only by responsible individuals, who are familiar with the machine. • Before connecting the mower conditioner to the tractor, be sure the tractor meets minimum horsepower requirements and is ballasted to control the unit, especially when operating in hilly terrain. • DO NOT work around machinery wearing loose clothing that could get caught in the moving parts. • Always disengage the PTO, lock the tractor brakes, and shut “OFF” the tractor engine before leaving the tractor seat, lubricating the unit, cleaning or unplugging any part of the machine, or adjusting the machine. • Never stand behind the mower conditioner while it is running. Stones or other objects could be thrown from the unit unexpectedly. • Always lower the header to the ground or engage the transport stops before working around the machine. • Keep all shields in place. Never work on, or operate a machine with shields open or removed. DO NOT modify any shields and always reinstall or close all shields after working on the machine. • DO NOT start the machine until you know that everyone is clear of the machine. • Always operate the unit at rated PTO speed, (540 or 1000 RPM) for which the unit was designed. • Always use the header transport stops, pivot lock and spring loaded tongue safety lock when transporting the machine. • Always use SMV emblem, adequate lights and safety warning devices when transporting the machine on public roads. Check with your local law enforcement agencies for specific requirements for your area. • Limit towing speeds to 20 MPH maximum. Be constantly aware of the size of the machine when maneuvering in traffic. • Use the safety chain when transporting the unit on public roads. • DO NOT weld on wheels. Welding on wheels may cause high stress and a wheel failure. • DO NOT weld on wheels with a mounted tire. Welding on wheels with a mounted tire may cause the tire to burst, causing death or serious injury • If your Operator's Manual becomes lost or damaged ask your dealer to get you a new manual for your unit. BASIC CONFIGURATION SPECIFICATIONS Mower conditioners combine cutting and conditioning of the crop in one machine. Haybine® sickle mower Conditioners are equipped with a push bar, sickle cutter bar, conditioner system with rubber rolls, swath gate, and windrow shields. Economic Model 472 is a side-pull mower conditioner, with a 7' 3" cutting width, while the 488 cuts a 9' 3" swath. The 9' 3" 1465 is equipped with a 5-bat reel and frame mounted conditioner rolls, resulting in a “lightweight” header that floats freely over obstacles and undulations in fields. The 1475 center pivot trail frame can be matched up with 3 different HS sickle headers for cutting widths of 14' 3", 16' 3" or 18' 3". The center pivot tongue, allows the operator to pivot the header and trail frame to cut on either side of the tractor. It also gives the operator more maneuverability for cutting around obstacles in the field. The pushbar leans tall crops forward so the crop can be cut by the sickle. The cut end of the crop is fed into the conditioner rolls by the reel. The momentum of the crop leaving the conditioner rolls is then deflected by the swath gate into a swath Like the 1465, the pivot-tongue 499 utilizes the “lightweight” or through the windrow shields into a windrow. The right and header design with 12' 3" cutting width. The exclusive left crop dividers may be installed in tall crops to help separate New Holland Rolareel smoothly moves crop from the the uncut crop and the crop to be cut and guide the material sickle into the conditioner rolls. under the pushbar. 3 SERVICE INSPECTIONS Take Full Advantage of its Capabilities ■ Getting the most from your New Holland mower conditioner is the purpose of this booklet. ■ New Holland wants to help owners achieve peak efficiency from all of their equipment. Have you, or someone you know, purchased a new mower conditioner in the last few years and continued to use it in much the same way as the mower conditioner it replaced? Many times we fail to take advantage of the advanced features available on today’s modern equipment. As a result the owner may not be getting all the value from the money spent. Many of the items suggested in this booklet can be completed by the owner when preparing for the season or by the operator when starting a new field. Other adjustments, service procedures, or repairs might be more effectively completed by your dealer’s trained service technicians. New Holland Maintenance Inspections — prepare your mower conditioner for peak performance Ask your New Holland dealer about New Holland Maintenance Inspections. It is a proactive way to be sure your mower conditioner will operate at its best possible performance in demanding conditions. New Holland Maintenance Inspections include a visual and functional inspection of your mower conditioner. They can be used as a pre-season or as a post-season tune-up. Benefits include: • Increased productivity • Less downtime during the season • Lower operating costs • Improved fuel economy • Documented maintenance • Serviced by New Holland-trained service professionals • Serviced with Genuine New Holland lubricants, kits, and parts The combined advantages of New Holland Maintenance Inspections should result in a lower cost of ownership and higher resale values.

Improper tractor hook-up may result in PTO drive shaft failure; damage to the hydraulic pump or hoses; improper header flotation; incorrect cutter bar angle and poor crop feeding. The model 1475 Pivot Tongue mower conditioners are 540 or 1000 RPM, depending on the hydraulic drive pump the unit is equipped with from the factory. These units require a minimum of 60 HP, with standard ASAE hitch and PTO locations. The tractor used to operate these models must be equipped with two, remote hydraulics with a minimum operating pressure of 1800 PSI. Adjust the tractor tread width so the wheels do not run over the windrow. Use a tractor with sufficient ground clearance to prevent crop from snagging and bunching on the underside of the tractor. Model 472, 488 and 1465 Side Pull mower conditioners are designed for 540 RPM PTO input only. The tractor must have a minimum of 30 (472) or 35 (488 & 1465) PTO HP with standard ASAE hitch and PTO. Hydraulic header lift is optional in the 472 and 488, and standard on the 1465. The tractor must also be equipped with at least one remote hydraulic outlet, with a minimum operating pressure of 1800 PSI for operating a single acting hydraulic cylinder. “D” “A” “C” “B” The 499 is equipped with a hydrostatic 540 or 1000 RPM PTO drive system. A minimum of 60 HP is required for optimal performance, and two remote hydraulic outlets are required for header lift and pivot functions.

Option 1: used on tractors where the drawbar cannot be adjusted to 20-24" from the end of the tractor PTO shaft to the center of the hitch pin hole. Drawbar extension is required to provide the required 22-24" dimension. 5. Option 2: used on tractors where the drawbar CAN be adjusted to 20-24" from the end of the tractor PTO shaft to the center of the hitch pin hole. No extension is required. Re-arrange mower conditioner hitch plates or adjust the hitch position to achieve a level tongue and PTO driveline orientation. 6 OPERATION Side-Pull Mower Conditioners • Adjust the hitch on the mower conditioner so the telescoping PTO assembly is as level as possible 499/1475 The drawbar extension MUST BE USED for sharp turns to ensure proper pump installation on the tractor PTO and to prevent damage to the pump and hoses. • Attach the drawbar extension to the tractor drawbar and securely tighten all hardware • Pivoting the tongue will put heavy side loads on the tractor drawbar 499/1475 - Attaching 540 RPM pump/gearbox assembly or the 1000 RPM pump/coupler to the tractor • The 1000 RPM pump connects directly to the tractor On some tractors, it may be impossible for the torque arm to contact the drawbar when the pump is completely on the tractor PTO shaft. Modification of the torque arm by a dealer will be required. • The chain secures the torque arm to the drawbar to prevent rotation of the pump and gearbox assembly and prevents the pump from sliding rearward off the PTO shaft • Loop the pump chain around the drawbar and drawbar support as tightly as possible. Secure the chain in the keyhole slot in the bracket. • Make necessary electrical connections for transport warning and turn signal lights (see figure 7.2) • Newer tractors have a mating lighting connector, with wiring compatible with the mower conditioner circuits. Older tractors may require addition of wiring connections for proper lighting operation. PTO shaft and no gearbox is required (see figure 7.1) • The 540 RPM step-up gearbox input shaft and pump orientation can be changed to gain proper gearbox clearances. Contact your dealer for proper gearbox/pump setup for your tractor. • Gearbox may be installed with the input shaft in the top position and the pump in the bottom position • Pump in the top position and the input shaft in the bottom position • The weight of the pump can result in difficulty when Figure 7.1 removing the pump from the tractor PTO shaft. Grease the tractor PTO shaft with molybdenum de-sulfide grease prior to installing the pump to allow easier removal. IMPORTANT: If the 540 RPM pump/gearbox or 1000 RPM pump is not installed correctly, failure of the PTO shaft and pump assembly may occur. 1 2 6 7 • Slide the pump assembly completely onto the tractor 5 PTO shaft • The pump torque arm must contact the side of the 4 drawbar. Adjustment of the torque arm may be required for proper hook-up. 1. Ground 2. Not used 3. Directional, left 4. Brake lights 3 5. Directional, right 6. Tail Lights 7. Not Used Figure 7.2 7 OPERATION Transporting the Mower Conditioner When transporting the mower conditioner on public highways, configure the unit for the narrowest possible transport width. Figure 8.3 Basic Mower Conditioner Adjustments and Configuration Figure 8.1 • Pivot the side pull mower conditioner tongue to the transport position and engage the swing cylinder lock, to prevent cylinder movement • On center pivot units, position the tongue in the center of the header and engage the spring loaded tongue pivot latch pin at the rear of the tongue (see figure 8.1) To obtain top performance from the mower conditioner, the following steps should be followed. Header Flotation The header flotation should be set so a 70 lb. lifting force at each end will start to lift the header from the ground (see figure 8.4). • Increase the tension on the flotation springs in stony conditions to reduce header flotation force to 35-50 lbs. • If the header is too light (springs tight), the header will bounce creating uneven cut height, poor crop feeding and poor windrow or swath appearance. The header will take too long to return to cutting height after riding over an obstacle, leaving uncut material. • If the header is too heavy (springs loose), the header will Figure 8.2 Additional Steps for Safe Road Transport • Raise the header and engage the header lift locks then not float properly over obstacles causing cutter bar, guard and knife damage effecting guard/knife alignment and adjustment. This then will affect cutting and feeding of the crop. • Do Not Exceed 150 lb. flotation force. Cutter bar or header damage may occur. lower the header onto the locks (see figures 8.2 and 8.3) • Attach the safety chain from the mower conditioner to the tractor IMPORTANT: Changing the drawbar height will change the flotation setting. Re-check flotation if the mowerconditioner is used on a different tractor. • Be sure the SMV(Slow Moving Vehicle) emblem is visible from the rear when the mower conditioner is in the transport position • Use transport lights, amber flashing, and red tail/stop lights • The mower conditioner is also equipped with reflective tape. Keep the reflective tape clean and in good condition. If the tape becomes damaged contact your dealer for new decal tape strips. 8 1465 499 1475 Figure 8.4 OPERATION Cutting Height The cutting height is controlled by skid shoe height setting and cutter bar angle, adjusted with the header tilt cylinder or link (see figures 9.1-9.3). Cutter Bar Angle Normal cutting conditions • Adjust the guard angle to the 7˚ mid-tilt range Tough cutting conditions 499 • For down crop, increase the guard angle to maximum tilt Figure 9.1 of 10˚ • For dead, wet undergrowth, reduce the guard angle to minimum tilt of 4˚ Rough or stony conditions • Set the guard angle to minimum tilt of 4˚ Skid Shoe Settings Changing the skid shoe setting will change the header flotation. After adjusting the skid shoe setting, re-adjust the header flotation as required (see figure 9.4.) 1475 Figure 9.2 Normal cutting conditions • Set the skid shoes at the desired cutting height Tough cutting conditions • For down crop, raise the skid shoes to lower cutting height to get under the down crop • For dead, wet undergrowth, lower skid shoes to raise cutting height For rough or stony conditions • Lower skid shoes to raise cutting height 1465 Figure 9.3 Figure 9.4 9 OPERATION Sickle and Guard Inspection and Adjustment As the name implies, the sickle guards protect the sickle from damage due to contact with the ground. The guards also help lift the crop, and the guard ledger surface is the secondary element of the “scissor action” that cuts crop, the primary element being the sickle sections. The guards are the bearing surface that holds the sickle in the correct front-to-back position. Guards must be in good condition and properly adjusted for best cutting performance (see figure 10.1). • The edges of the ledger surface must be square to provide the best shearing surface with the sickle Figure 10.1 • Guards must be adjusted so the rear of the knife section bears on the rib, and the front of the section lies flat on the ledger surface • Adjustment is accomplished by applying vertical force to the guard, bending the guard tip to achieve the desired alignment Knife Hold-down Clip Adjustment Headers with standard guards have adjustable hold-down clips spaced across the cutter bar. The lip at the rear edge of the clip holds the rear of the section in place (see figure 10.2). Figure 10.2 • There should be a clearance of 0.005 - 0.025" between the knife section and the clip • Adjust the clearance by tightening the nut to obtain a clearance of less than 0.020" between the clip and knife section • If the clearance is less than 0.020", the knife may not move freely A . 010" shim may be required between the knife clip and cutterbar to obtain the proper clearance Figure 10.3 Optional stub guards are used in applications such as tangled or down crop where more aggressive cutting action is required (see figure 10.3). • Guards are shorter to expose more of the sickle section to the crop • Stub guards do not have an upper guard tip over the sections. Full width hold-down clips must be adjusted to hold the sickle sections flat on the ledger surface (see figure 10.4). Figure 10.4 10 OPERATION Knife Hold-down Clip Adjustment (cont.) Larger headers use two counter-stroking knives, which overlap by two sections in the center of the cutter bar. • Proper shimming of the guards and hold-down clips is required, to allow the knives to overlap properly in the center of the cutter bar. (When shimmed properly the left knife assembly should be 0.120" lower than the right knife assembly) (see figure 11.1). • When removing and installing guards and knife holddown clips, ensure that shims are re-installed properly Special end guard All guards to right of center guard (except end guard) are standard guards Special center guard All guards to left of center guard (except end guard are standard guards Additional sickle adjustments include knife timing and sickle drive adjustment. Special end guard • Dual, counter-stroking knives must be timed so both knives Figure 11.1 reach the inner end of the stroke at the some time, to minimize vibration and provide the best cutting performance • Knife drive adjustment is necessary to keep the knife back centered in the guard opening (see figure 11.2). ➁ Reel Settings Normal cutting conditions • Reel speed-set approximately 10%, or 1-2 MPH faster than forward ground speed (see figure 11.3) Excessive reel speed will tend to damage or strip leaves from legume crops such as alfalfa. ① Figure 11.2 • Reel timing–set to deliver the crop to the middle of the conditioner rolls or the bottom of the auger. If the release point is delayed, crop can be carried over and thrown forward by the reel. If the release point is too early, the crop may not be fed evenly to the conditioner rolls or auger. • Reel location–set in the mid-range of the front-to-rear adjustment and set at a height with approximately 1/2" clearance to the tops of the guards and floor area between the guards and the auger or conditioner rolls (see figure 11.4). Down, dead, wet undergrowth conditions. Figure 11.3 • Reel speed–increase reel speed. The release point may have to be changed to release the crop earlier to prevent carryover. • Reel timing–set to deliver the crop to the bottom of the auger (HS headers only) • Reel location–move the reel to the front position and down so the reel tines just clear the tops of the guards Short crop, under 18" tall • Reel timing–delay reel timing to deliver the crop higher to the auger • Reel location–adjust reel up and back Figure 11.4 11 OPERATION Reel Settings (cont.) Adjust the pushbar so crop is pushed down sufficiently so the reel can move material smoothly into the conditioner rolls after being cut (see figure 12.1). Pushbar extensions may be required if tall crops fall over the pushbar and into the reel. Roll Gap The roll clearance and pressure should be adjusted to obtain 90% of stems being cracked and 5% of the leaves being damaged, with dark marks on the leaves (see figures 12.212.4). Figure 12.2 Normal cutting conditions Roll Gap Shims • Roll gap, (1/64"-1/8") Thick stemmed crops • Increase roll gap to (1/4") or greater Minimum roll clearance should be checked in multiple positions to allow for variation or runout in the roll. Rolls must be timed and adjusted so the two rolls never contact. Extreme vibration and high stress on the drive system will result from roll contact. Figure 12.3 • Roll timing is adjusted with a slotted sprocket or universal joint drive hub on one roll (depends on model) HS Headers Contact your New Holland dealer for assistance when making critical adjustments to roll clearance and timing. Roll Pressure The roll pressure adjustment varies the amount of force required to allow the upper roll to move upward as the crop mat passes through the rolls (see figures 12.4 and 12.5) Roll Pressure Adjustment Roll Gap Adjustment • Adjust pressure as required to achieve the level of conditioning desired Figure 12.4 Figure 12.1 12 Figure 12.5 TROUBLESHOOTING PTO AREA SYMPTOM SUGGESTED ACTION Mower

partially NOTE #1: NOTE #2: NOTE #3: In cane crops, sometimes it is better to have the auger-to-stripper clearance as close as possible and sometimes it is better to have the auger fully raised. The type and volume of Table 17.1 crop will determine which is better. Paddles can be added or removed from the auger to aid in making windrows or swaths. The determining factors for adding or removing paddles are: header width, volume of crop, and windrow or swath width. For extra wide cut width, it is necessary to move the crop further into the center of the header for a uniform windrow or swath. Set your windrow or swath width and then add or remove paddles to obtain desired windrow or swath. The HS16 headers do not come with the two outside paddles. In some instances, lowering the push bar all the way down and slowing ground speed, in very tall timothy or cane crops may help feeding of crop.

(Not enough conditioning) Over conditioning Material being crushed with minimal amount of roll tension Optional Equipment Crop Dividers Left crop divider • The left crop divider may be installed on the left side of the cutter bar when cutting tall crops, to help guide the material under the push bar and to the inside of the left header side sheet. Right crop divider • The right crop divider may be installed on the right side of the cutter bar when cutting tall crops to help divide the material being cut from the uncut material. Push Bar Extensions • Push bar extensions may be installed in tall crops to push 18 the top of the material forward. The knife will cut the material and the reel will feed the cut material cut end first into the conditioner rolls. • If the top of the material is not pushed forward the reel will feed the top into the conditioner rolls before the material is cut off. This condition will cause, poor cutting, cutter bar plugging, reel carry over, and roll wrapping. Stub Guards • Stub guards may be installed to replace the standard guard when cutting crops with dead, wet, and new under-growth that plugs the standard guards. When cutting this type of crop the material will hang up on the standard guards causing plugging of the cutter bar.
