Suspension & Speed Reduction
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.
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.
Tine vs. Roller Conditioners
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 – 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 adjusted via a spring-preload mechanism, which also protects the rollers from foreign objects. Adjustable swathing plates allow for variable swath formation.

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 – so no inner shoe is required and optimal crop flow is ensured.
MAX CUT
1. Wave-shaped base plate allows mowing discs to be placed well to the front.
2. Optimum tunnel effect, further increased by skids with spoiler action.
3. Innovative bolting concept for maximum deflection and impact resistance.
4. Permanently lubricated maintenance-free mower bed for maximum service life.
5. SAFETY LINK safety modules protect the mower bed in the event of collisions.
6. Formed hardox inserts between skids for a clean cut.
7. Very small mower bed openings for maximum strength.
