That's why it makes sense to have a reliable partner who can supply you with much more than just rugged machinery – you also need outstanding product quality and excellent customer service for example, and the means to tackle every stage of harvesting from mowing, tedding and swathing to field clearance with maximum efficiency and no bottlenecks. Our expertise and experience have made us one of the world's leading providers of equipment for systematic forage harvesting. But we've always kept our feet on the ground, so whether you're farming 10, 100 or 1,000 hectares, you'll be sure to find the right package in our product range, guaranteeing you highestquality forage. CORTO drum mowers: powerful, reliable and rugged. Quality mowing design, universal applications. CORTO drum mowers offer fast, dependable mowing with high work rates. They achieve superb results over smooth fields as well as soft and damp surfaces. You can rely on CORTO drum mowers whether you prefer mounted, front or trailed machines – you have the widest choice. The frame – rugged and durable. • Box section steel transmission housing. • Top torsional resistance for long service life. Tough mowing drums. • Straightforward design with high rigidity. • Large sized gears transmit power dependably year in, year out. • The rigid centre shaft provides support for the entire mowing drum. • The drum can be dismantled quickly since all the bearings are mounted on the centre shaft. Extra spacer rings can be added to further increase the cutting height by 12 mm. The heavy belt drive delivers reliable power transfer and high output. All the components in the drive line are designed for heavy duty applications. The transmission housing has immense torsional resistance, maintaining output at its peak year in and year out. 4 Crop flow is fast and smooth. • The mowing drums feature a wide opening to encourage the rapid flow of the crop with no upsets or lumps. Smooth and consistent crop flow helps produce clean swaths. Quick knife changing. • • • • Quick and easy. No additional tools required for changing the blades. Reduced downtime. If for difficult conditions you need to increase the cutting height, added disc height is available by fitting spacer discs underneath. Mowing drums 5 Only the best. Efficient operation. Regardless of which mower you opt for, the conditioning system, which has proven itself time and again in largescale operations, is featured on all CLAAS mowers. No compromise in either conditioning consistency or long-term durability. • The layer of wax that prevents evaporation is opened up by the conditioner, speeding up the drying and wilting process appreciably. • Time is saved with fewer working steps. Whatever the weather. A good mowing job alone is no guarantee of a high quality crop – accordingly nearly all CORTO mowers can be fitted with the exceptionally efficient CLAAS conditioner. Dry matter with conditioner without conditioner 6 Steel tines are the benchmark. • Durability with high quality, V-shaped and hardened spring steel tines. They're arranged in an offset position for years of trouble-free operation. • The tines are composed of two individual parts that individually separate if an obstruction is hit. • Protection against damage enhanced due to the rubber mountings on the tines. CORTO drum mowers with tine conditioner – faster drying and wilting. Rapid drying. Securely mounted. • You can match the conditioning intensity to the harvest conditions by adjusting the baffle plate, without the need for tools. • The conditioning effect can be modified still further by turning around the asymmetric tines 180°. • Adjustable swathing plates for the optimum swath width. • The conditioner rotor is mounted in heavy-duty block bearings, which cope best with the high forces during mowing and minimise wear and tear. • The bearings are fitted outside the crop flow so they are well protected from dirt and corrosive crop sap. • Easy removal and replacement of the rotor for maintenance purposes. Precision adjustment. The degree of conditioning is easily set by adjusting the baffle plate angle with an externally mounted lever. Conditioner 7 At home on every field. The compact and sturdy design enables easy handling and control. With working widths of 1.85 and 2.10 metres, CORTO rear-mounted drum mowers are your reliable partner when it comes to forage harvesting. Whole width mowing. The three-point-mounted CORTO can be matched to every track width and tyre type. • The mounting pins for the lower linkage are easily adjustable to match the mower to the tractor width. • The full mowing width can be utilised regardless of what sort of tractor is pulling it. • Front and rear combinations can be accurately set up in combination. Switching over from the transport position to the mowing is carried out by remote-controlled unlocking in the breakback device and automatic locking in the desired position. 8 CORTO 185 N and 210 N – quality and reliability. A pleasure to use. • The flexible drive via four belts is a reliable power transfer method, quiet in operation, and prevents overload between the tractor and the mower. • You can check the tension of the belt against a mark and tighten it without tools. • Access to the principle components is easy thanks to panels that open up fully for checking, cleaning and maintenance. • Changeover from work to transport position from the cab. • Automatic transport lock. • Optional hydraulic lifting for road travel. • Optional conditioner. Reliable overload protection. The overload protection prevents damage caused by obstacles. When the mower hits an object it swings back automatically. Just back up, the mower re-engages and you continue mowing. On CORTO mowers the belt can be checked in seconds and the tension adjusted without the need for tools. CORTO 185 N CORTO 210 N 9 CORTO 270 N and 310 N – thoroughbreds with three-point hitching. 10 Performance and mowing quality. Constant ground pressure. Four mowing drums characterise these models designed for fitting to the three-point linkage. Highly manoeuvrable and reliable CORTO quality for higher acreage in less time. Whatever the conditions, you can be sure of covering greater areas with first-rate results. • Three powerful springs transfer a considerable portion of the mower’s weight onto the tractor. • The ground pressure across the four drums remains constant. • These mowers smooth out uneven patches and glide gently over the full working width, taking even large bumps in their stride. • Uniform mowing pattern. • Stubble is treated gently. Adjustable mounting bolts. • Quick matching to the tractor width. • Full utilisation of the mowing width. • Full mowing width with front and rear combinations. Excellent weight distribution. • High rigidity is attained by precise matching of the threepoint hitching and mounting frame to the weight of these big mowers. Perfect ground contour following. The spring suspension works impeccably, even in very difficult mowing conditions. The mower glides lightly over the ground thanks to the excellent counterbalance of the springs. CORTO 270 N CORTO 310 N 11 Ingenious single-lever control. You control two important functions with a single-acting control unit and without using the three-point linkage: 1. Horizontal lift at the headland 2. Full lift into travel position. Ease of use. The mower is swung back without you having to get off the tractor. The machine is automatically locked into the transport or working position when you drive backwards or forwards. 12 CORTO 270 N and 310 N – easy to control. Safe on the road. • There are three ways you can travel on the road with the mower: –– Raise it hydraulically to the side. The fulcrum point is located well inboard, making the mower only slightly wider than the tractor on the road. –– Swing it back to pass through narrow or low openings, for example. –– Swing it back and then raise the mower hydraulically to place the weight in the middle of the tractor. • The mower is raised with a single-acting hydraulic cylinder. • Automatic locking for road travel. CORTO 270 N CORTO 310 N 13 CORTO 270 NC – easy crop conditioning. An ideal combination. The CORTO 270 NC from CLAAS is a rear-mounted fourdrum mower plus conditioner. It adds up to a powerful combination for large farms and contracting work when paired up with the CORTO 3100 FC, providing a combined mowing width of up to 5.50 metres. Convenient single-lever control. • Parallel horizontal lift on headlands using the tractor hydraulics. • When in the transport position, the three-point linkage is not used, so the basic setup remains unchanged. Narrow dimensions on the road. The mower-conditioner also features three separate ways of driving on the road. –– Swung back. –– Swung back and then raised hydraulically. –– Raised hydraulically to the side. The mower is swung back without you having to get off the tractor. The machine is automatically locked into transport or working position by driving backwards or forwards. 14 • The mower is raised with a single-acting hydraulic cylinder. • Automatic locking for road travel. Variety of swaths. • Stepless adjustment of the swath former at the side of the conditioner housing. • Swath width variable from 1.00 to 1.60 metres according to the tractor track width. • By adjusting the baffle, the degree of conditioning is matched to the harvesting conditions and the crop type. Crop spreading cowl standard. • Full-width, fluffy swaths are the ideal solution for reduced drying times. • Baffle plates adjustable without tools. • No need for tedding. Efficient and trouble-free crop conditioning thanks to the direct power flow via an angle drive and drive shaft. CORTO 270 NC 15 Plenty of mowing width. These trailed CORTO mowers have over three metres mowing width and an independent chassis which makes them a perfect choice for big tasks. Despite this big mowing width, these mowers are highly nimble and can accomplish tight turns in a minimum of space. Powerful drive. • The swivelling drive head detects all changes of direction of the drive line between the tractor and the mower, and the tightest of turns are possible without the risk of bending the drive shaft and with minimum wear. • Flexible and dependable mower drum drive with four belts for reliable power transfer. The extra-heavy flange and large bolts of the four drums on the gear frame demonstrate that this mower is built for long service in arduous forage harvesting conditions. 16 CORTO 3100 N and CORTO 3100 NC – the premier league. Versatile in the extreme. • Match the mower to the tractor width with three hydraulic cylinder positions installed on the mower. • The mower can be swung back hydraulically from the transport position to the working position and vice versa with a double-acting hydraulic connection fitted in the cab. Hydraulic wheel lift. • You can run across the swath with a lift height of up to 400 mm. • Plenty of ground clearance on rough paths and tracks. • Large tyres with grooved tread pattern keep the mower on track, even on slopes. Optional conditioner. • CORTO 3100 N with mobile swath formers. • CORTO 3100 NC with tine conditioner. Intelligent spiral spring suspension enables you to match the ground pressure to the prevailing field conditions. CORTO 3100 N CORTO 3100 NC 17 CORTO front mowers – for finest working quality. Best view of the field ahead. Mounting the mower in front of the tractor ensures the best possible visibility over the mowing area, regardless of farm size or tractor size. The front mowers' contour-following characteristics are unrivalled, making for a clean and uniform cut. High work rates are a foregone conclusion with these mowers, particularly when they are teamed up with a rear mower or forage wagon. The CORTO front mower family comes in mowing widths from 2.65 to 3.05 metres. You'll be sure to find the right model for your business. When used together with a trailed or rear-mounted mower, you can achieve working widths of up to 6.00 metres. Go anywhere with these mowers. The different three-dimensional ground following systems built into all CORTO front mowers ensure an optimum cut every time. • Proven and patented CLAAS suspension on the CORTO 270 FN, 290 FN and 3100 FC. • PROFIL – the new contour-smoothing generation with added control underneath the mower frame on the CORTO 275 F and 3150 F. 18 Perfect balance. The weight of these CORTO mowers is transferred to the tractor by strong springs. This reduces the ground pressure, which in turn reduces the power required. The stubble and the drum glide discs are all treated gently, while the mower stays in line, even over hilly terrain. Nothing's been overlooked. Even travelling through narrow passages is made easy in the transport position on CORTO front-mounted mowers. CORTO front mowers 19 Plenty of mowing muscle. CORTO – FN productivity. The forte of these four-drum front mowers is trouble-free coverage of very big acreages. You can run them on their own or add to mowing speed by fitting a rear mower in unison. High output doesn't break the bank either – good value for money was the aim so you get a broad mowing width and a fixed mowing height. • Patented front mower suspension for perfect ground contour following. • Evens out the bumps fore, aft and sideways, regardless of the tractor angle. • A clean cut across the full working width. • Stubble is treated gently. • Best-quality clean forage. Compact and straightforward. • During transport, bounce is minimised thanks to the centre of gravity being near to the tractor. • Good visibility on the road. • Reduced transport width with folding covers on each side. When conditions are rough and a higher cut is needed, the drums are raised using added glide plates fitted underneath. 20 Smooth crop flow. • The mowing drums are designed for a fast crop flow, even without a conditioner or other feed-enhancing device. • Optional 750-rpm shaft speed. CORTO 270 FN and CORTO 290 FN – rugged and reliable. Two adjustable swathing discs are fitted as standard, leaving a well-shaped swath between the tractor’s wheels. A second pair of swathing discs is available optionally. CORTO 270 FN CORTO 290 FN 21 CORTO 3100 FC – a front mower with conditioner.
