CLAAS MAX CUT mower bed now available from 2.2m working width

CLAAS is introducing new rear side-mounted mowers to replace its DISCO Inline and DISCO 50 series from the summer of 2020. The nine brand-new models not only include numerous useful features but also the proven MAX CUT mower bed and cover working widths from 2.2 to 3.4 m.

The mower bed, developed and manufactured at the CLAAS site in Bad Saulgau and launched on the market in 2015, is synonymous with the best cutting quality combined with extremely smooth operation, reliability and low drive requirements. Special attention was also paid to wear protection and durability, among other things. The shape of the bed means that the large pinion gears of the cutting discs are mounted particularly far forward, which allows the largest possible overlap between discs, and in addition they engage with several teeth at two points in each case. Uniform disc spacing also ensures an even cutting pattern. Shaped from one piece of steel, the wave-like shape of the mower bed, which is permanently lubricated, together with the specially shaped skids creates a dirt-repelling tunnel effect. The specially hardened inserts between the skids are shaped differently on the inward and outward moving mowing discs, which provide effective protection and optimum crop flow, but also act as a shear bar for a perfect cut. The MAX CUT mower bed is equipped with the SAFETY LINK safety module as standard, which features a predetermined breaking point on each cutter disc that disconnects the disc from the drive train, but is prevented from flying away thanks to an axial bolt.

New centre-of-gravity hitching for side-mounted DISCO mowers

A new feature for all side-mounted DISCO disc mowers is a centre-of-gravity hitching, which ensures that the mower bed, much like mowers with centre pivoting, has a uniform contact pressure over the entire working width. The large suspension spring engages in the middle of the machine frame in this case. Furthermore, the line of force of the spring runs exactly through the centre of gravity of the mower unit. The force is evenly distributed to the mower bed by the inner and outer support. The result: clean forage and an even cut to an absolute professional level.

DISCO 10: Maximum cutting quality with low weight

CLAAS is now introducing the MAX CUT mower bed, familiar from the DISCO family and proven thousands of times over, to the entry-level segment of disc mowers with the three new DISCO 24, DISCO 28 and DISCO 32 side mowers with working widths from 2.2 to 3.0 m and simple configuration. The DISCO 10 series mowers have the usual sturdy design despite their low operating weight, whereby the designers have succeeded in further reinforcing areas subject to high loads and optimising less stressed areas such as the outer covers. 

The DISCO 10 series can work on upward slopes of up to 45°. The mechanical breakback mechanism for the mower bed immediately responds to collisions and releases the mower bed to the rear. It automatically re-engages when reset.

A drive with a double gearbox comes as standard, allowing an extremely narrow transport position and a new folding angle of 95°. The powerful belt drive attenuates load peaks and can be tensioned without tools using a rotary knob. As is the case with previous models, the power flow is directly fed into the inner mowing disc from above, which means that no inner shoe is required and efficiency is increased. The PTO shaft speed can be reduced from 540 rpm to 480 rpm in light crops or when topping, which significantly reduces diesel consumption.

The ease of maintenance is also well thought out. The mower bed is freely accessible over the entire working width thanks to the wide opening of the protective covers. The blades are either bolted or available with a quick change mechanism depending on the place of use. Various mounting options, the Quickhitch mounting frame and the lower attachment of the left-hand lower link pin make mounting on the tractor easier.

DISCO 100: optionally with or without conditioner

The DISCO models 360 and 320 with working widths of 3.0 and 3.4m are now available within the DISCO CONTOUR series. These again have the new mechanical centre of gravity and suspension springs – that are adjustable without tools. The MAX CUT mower bed is just as high quality as in the large DISCO models and ensures maximum and lasting operational efficiency with permanent lubrication and speed reduction. The DISCO 100 series also features a double gearbox, integrated breakback device and quick blade change. The sturdy design guarantees a maximum service life.

The new transport folding to 105°, i.e. over the centre of gravity, always ensures safe transport even with lighter tractors. In keeping with the principle of “see and be seen”, the field of vision of the tractor’s rear-view mirrors is not restricted by the mowing unit and the rear lights are not obscured. The new double-acting hydraulic ram ensures a reliable and safe folding process even on hilly ground. It also provides end position dampening.

In addition, four different models with tine or roller conditioners, working widths from 2.2 to 3.0m and 95° transport folding are available for special requirements:
DISCO 240 RC, DISCO 280 C, DISCO 280 RC and DISCO 320 C. While the DISCO 240 RC comes with a roller conditioner as standard, the DISCO 280 is optionally equipped with a tine or roller conditioner. The DISCO 320 C has an integrated tine conditioner.

A headland stop is fitted as standard on all models with conditioner and is optionally available for models without conditioner. The optional trestle allows space-saving and at the same time safe storage in the transport position.
