CLAAS has launched the two most powerful belt grouper mowers on the market for tractors up to hp – the DISCO C AUTO SWATHER and DISCO RC AUTO SWATHER. These mowers have been specifically developed for harvesting lucerne, whole-crop silage and winter forage alongside traditional grass crops, with the focus on maximum yields and forage volumes. The harvested crop is gently and effectively crushed without loss by two counter-rotating polyurethane rollers. Furthermore, the conditioner extends across the entire width of the mower bed to avoid any forage jams.

On all DISCO models, the new swinging arms can be hydraulically pivoted outwards by mm and inwards by mm (maximum travel mm) to adjust the overlap when turning corners and working across slopes. This helps to avoid unmown strips. The swing arm travel can be infinitely adjusted from the cab between . and . m.  When opening the field and mowing on slopes, the overlap can be variably increased giving up to cm on each side to ensure stripe-free mowing, even with these applications. When folded into transport position, the arms automatically retract to a height of less than . m.

The innovative hitch frame with angled arms ensures optimum centre of gravity at the headland and on the road – for added soil protection and road safety. The two models with AUTO SWATHER swath grouping feature a reinforced headstock. Hydraulic hoses (fitted with Kennfixx couplers as standard) and electric cables are safely stowed in a new parking bracket when the mower is unhitched. A central lubrication system which supplies all lubrication points except the drive shafts is optionally available in some countries for both AUTO SWATHER models.

The new large-scale mowers combine tried and tested features such as MAX CUT mower beds with quick knife change and ACTIVE FLOAT suspension with innovative new developments. This all adds up to clean forage, maximum sward protection and high capacity paired with high cutting frequency at a PTO speed of only rpm for optimum efficiency. The new, flow-optimised wear skids first introduced on the DISCO , DISCO and DISCO in that extend the cut height by mm are also available for all DISCO as well as all front mowers. They not only reduce crude ash contamination and speed up regrowth – they also reduce tractive power requirement and diesel consumption by providing enhanced grass sward protection.

The ability to automatically create multiple reference lines per field provides a further efficiency boost. Using recorded or imported field boundaries, A-B lines and contours for different areas and sections of the field can be calculated and saved before cultivating the field. This feature simplifies work in irregularly shaped fields, as several headland sequences and rounded field boundaries can be saved as references in addition to the main working direction.
