2025 CLAAS Disco Rear Mowers 4000 Contour

DISCO rear mowers with MAX CUT mower bars are productive and reliable, whatever the conditions.

Features may include:

MAX CUT.

• Wave-shaped mower bed allows mowing discs to be placed well to the front

• Optimum tunnel effect, further increased by sliding skids with spoiler action

• Innovative screw concept for maximum bending and shape stability

• Permanently lubricated maintenance-free mower bar for maximum service life

• SAFETY LINK safety modules protect the mower bar in the event of collisions

• Formed hardox inserts between skids for a clean cut

• Very small mower bed openings for maximum strength

ACTIVE FLOAT enables you to respond quickly and easily to all sorts of different conditions, such as wet spots or dry hillocks, and non-uniform crop material. The mower ground pressure can be flexibly adjusted with a single-acting control unit even while the machine is working. The current setting can easily be read from a pressure gauge, which is clearly visible from the cab.

All DISCO disc mowers can be operated at a reduced PTO shaft speed of 850 rpm when conditions allow. This 'integrated economy PTO' significantly reduces fuel consumption."Reducing the PTO shaft speed enables farms to cut fuel consumption by up to 22% on average on average. With a DISCO 9200 C AUTO SWATHER, this equates to around 12 gpm (1.16 liters per hectare)." A student at Kiel University of Applied Sciences obtained these results in 32 field trials.

Tine conditioners with V-shaped tines in a spiral configuration are ideal for harvesting grass crops. Conditioning intensity is set via a baffle plate. Flexible mounting allows the tines to give way and pass around any objects that find their way into the conditioner – stones, for example. This avoids repair costs. As an option, the harvest crop can also be spread over the entire working width with a wide crop spreader, or deposited in a single swath with adjustable swathing plates.

Leafy crops such as alfalfa call for protective conditioning. The aim is to crush the stalks without destroying the leaves and thus wasting them. This is where the DISCO front mower unit with roller conditioner comes into its own. The durable, polyurethane V-shaped interlocking rollers crush the hard stalks while protecting the leaves. The conditioning intensity can be adjusted via a spring-preload mechanism, which also protects the rollers from foreign objects. Adjustable swathing plates allow for variable swath formation.

The CLAAS range of DISCO CONTOUR rear mowers provides suitable machines for all farms and agricultural businesses. This efficient all-rounder combines the outstanding performance of the MAX CUT mower bar with other DISCO advantages. The central suspension ensures perfect ground-contour following in all models. The 120° road transport position also makes the machine compact and safe on the road.

The mower units in the CONTOUR model series are suspended at the centre of gravity, so they can pivot freely and adapt to the ground contours. The correct adjustment height is indicated by arrow markings on the arm.

The construction of our machines is robust and clearly laid out, with mower components built for maximum strength and stamina. To protect the hydraulic components, they are integrated in the frame structure wherever possible.
