DISCO mower technology.

MAX CUT.

Wave-shaped base plate allows mowing discs to be placed well to the front
Optimum tunnel effect, further increased by skids with spoiler action
Innovative bolting concept for maximum deflection and impact resistance
Permanently lubricated maintenance-free mower bed for maximum service life
SAFETY LINK safety modules protect the mower bed in the event of collisions
Formed Hardox inserts between skids for a clean cut
Very small mower bed openings for maximum strength

Suspension.

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 spool valve even while the machine is working. The current setting can easily be read from a pressure gauge, which is clearly visible from the cab.

Speed reduction.

All DISCO mowers can be operated at a reduced PTO speed of 850 rpm when conditions allow. This 'integrated economy PTO' significantly reduces fuel consumption."Reducing the PTO speed enables farms to cut fuel consumption by up to 22% on average. With a DISCO 9200 C AUTO SWATHER this equates to around 1.16 litres per hectare, or around 7 litres per hour." A student at Kiel University of Applied Sciences obtained these results in 32 field trials.

Tine conditioner.

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 deflect and pass around any objects that find their way into the conditioner – stones, for example. This avoids repair costs. The mown crop can also be spread over the entire working width with an optional wide crop spreader, or deposited in a single swath with adjustable swathing plates.

Roller conditioner with polyurethane rollers.

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 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 continuously adjusted via a spring-preload mechanism, which also protects the rollers from foreign objects.

A double roller drive run via a specially designed scissor gear is optionally available – for maximum throughput in very bulky crops. Adjustable swathing plates allow for variable swath formation.

Roller conditioner with steel rollers.

Optional steel roller conditioners effectively handle even thick-stemmed crops like sorghum.

The specially designed roller profile with tapered edges ensures intensive conditioning and uniform wilting, even with heavy or wet material.

Steel rollers are particularly hard-wearing and ensure a consistently high throughput thanks to the double roller drive.

DISCO CONTOUR.

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 bed with other DISCO advantages. Central suspension ensures perfect ground-contour following in all models. The 120° transport position also makes the machine compact and safe on the road.

Another advantage: the modern, dark design not only looks good – it's also less susceptible to dirt.

Optimum ground-contour following.

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.

Solid construction.

One of the many outstanding features of our mowers is their robust and straightforward design. For example, the particularly rugged conditioner hood – made from wear-resistance Hardox steel. Its robust, hard-wearing construction reliably protects it from stones thrown up by tine conditioners and ensures a long service life.

Where technically feasible, hydraulic components are integrated into the frame to protect them from external influences.

Optional counterweights.

Stability is critical on sloping ground or when using lighter tractors. Optional counterweights noticeably stabilise the tractor-mower combination – for a smoother ride, better slope stability and safer headland manoeuvres.

Well protected.

All DISCO rear mowers have mechanical collision protection. The attachment is inclined at an angle of 15°, so that in the event of a collision, the mower swings back and over the obstacle. Mowing can then continue after briefly reversing to reset the mower.

Safe on the road –

The 120° transport position and centre of gravity located close to the tractor provide outstanding stability for safety and ease of handling on the road. There is also a mechanical lock system to hold the mower securely when in the transport position.

Roller conditioner with steel rollers.

Optional steel roller conditioners effectively handle even thick-stemmed crops like sorghum.

The specially designed roller profile with tapered edges ensures intensive conditioning and uniform wilting, even with heavy or wet material.

Steel rollers are particularly hard-wearing and ensure a consistently high throughput thanks to the double roller drive.

Durable and easy to pull.

DISCO 100 series with side suspension.

Another advantage: the modern, dark design not only looks good – it's also less susceptible to dirt.

Centre of gravity suspension.

The large suspension spring acts on the middle of the machine frame. In addition, the line of force of the spring passes straight through the mower's centre of gravity. The inner and outer support ensures that the force is transferred evenly to the mower bed.

The small spring additionally protects the mower bed drive. Our unique centre of gravity suspension brings the advantages of central pivoting suspension to the side-suspended models.

Drive line.

The mower is driven via especially low-maintenance PTO drive shafts that do not require a safety chain. The robust belt drive absorbs peak loads and is tensioned by means of a rotary knob without needing tools. From there the force is transferred to a double gearbox which delivers the drive input from above straight to the first cutting disc for optimal crop flow.

Mechanical collision protection.

The overload protection responds immediately upon collision with an obstacle by swinging the mower unit up and back. Mowing can then continue after briefly reversing to reset the mower. An additional support frame also protects the outer edge of the mower from damage.

Space-saving.

A separate support stand is available for space-saving storage. The mower can be transferred directly onto it from the tractor – with no additional supports required.

105° transport position

In the transport position the machine's centre of gravity shifts even further to the middle so that the tractor's rear wheels are as uniformly loaded as possible. The double gearbox allows for a narrow transport width and a clear view to the rear. A double-acting floating piston ram enables the mower to be folded safely on slopes, with gentle braking before it reaches the end point.

Light, agile mowing.

DISCO 10 series with side suspension.

All DISCO mowers have the same high-quality core technology – the MAX CUT mower bed – even from a working width of 2.20 m. After all, every field deserves the perfect cut.

Centre of gravity suspension.

The small spring additionally protects the mower bed drive. Our unique centre of gravity suspension brings the advantages of central pivoting suspension to the side-suspended models.

Drive line.

The fuel miser.

The transmission ratio enables the PTO speed to be reduced from 540 rpm to 460 rpm in lighter crops. This reduces diesel consumption without loss of mowing performance.

At home in the hills.

The DISCO 10 range has been optimised for sloping terrain, with specially reinforced components and an extremely weight-conscious design. This range is also ideal for mowing road ditches and embankments with inclines of up to 45°.

Easy access.

Both halves of the protective cover conveniently fold upwards to allow easy access for maintenance and cleaning. The outer edge of the cover, which is more prone to wear, can be replaced separately.
