Technology for professionals.

MAX CUT for maximum quality.

The enhanced satellite drive plus the benefits from a range of other drive design solutions give the MAX CUT mower bar unmatched efficiency performance. The wave shape enables the large satellite wheels to be placed at the front of the cutterbar, engaging at two points. Uniform disc intervals ensure a perfect cut configuration under all operating conditions. Only the highest-quality materials have been used, for maximum service life. The MAX CUT bar is permanently lubricated, and is maintenance-free.

  • The secret is in the wave design.

    Only the wave design can provide the space required for two unique connecting pieces, specially hardened for the purpose. The connection piece with a raised section where the knives run towards each other (left) operates like a shear bar, preventing clumps of dirt forming. It also protects the bar from cutting damage. And thanks to the slimline connecting piece on the right, as the knives move apart they clear the bar earlier, and start cutting immediately. The special design also ensures optimum crop flow.

  • Maximum pressing force.

    The core structure of the mower bar is the wave-shaped bed, stamped from a single piece, with a pressing force of 3,000 tons. This is the secret of MAX CUT, giving it the required underlying strength and allowing the inclusion of a host of unique technical details. The wave design is the only way to meet all the requirements for a mower bar today, efficiently and without compromise.

  • Ultra-precise bolt fit.

    The base and cover are machined together, resulting in an ultra-precise fit between the two halves of the structure. The innovative bolt  design also provides a perfect positive connection, for maximum deflection and impact resistance without the weakening effect of welding processes. And last but not least, the use of high-strength, fine-grain steel ensures maximum service life for the MAX CUT mower bar, even under extreme loads.

  • Superb quality cut through maximum overlap.
    DISCO disc mowers

    Perfect cut, thanks to the specially shaped connecting pieces: at the point where the knife pairs are moving apart, there is maximum overlap between the circles of rotation of the knives, boosting the cut surface area.

    DISCO disc mowers

    The familiar SAFETY LINK safety module has been further improved, and is larger than before. The pressed bed structure provides more design space, also making it easier to replace when required. The sealed double groove ball bearing ensures maximum service life. Each individual mowing disc is protected by a predetermined breaking point in the safety module, and is isolated from the drive train in the event of a collision. An axial bolt holds the mowing disc firmly in position.

Optimum results with ACTIVE FLOAT.

DISCO disc mowers

No two fields are the same. With ACTIVE FLOAT, you are able to adapt quickly and easily to changing conditions, such as wet spots or dry hilltops. The ground pressure of the mower can be flexibly adjusted with a single-acting spool valve, even while you are working. The currently selected value is displayed on a pressure gauge visible from the cab position.

  • Optimum ground-contour following and protection of the grass cover
  • Clean forage
  • Reduced power and fuel requirements
  • Low wear and tear
  • High working speeds
  • Frictional resistance becomes rolling resistance.

    ACTIVE FLOAT hydropneumatic suspension is standard equipment on all CONTOUR rear mowers from CLAAS, and is also available as an option on front mowers. This suspension system transfers the weight of the mower from the grass cover to the tractor. It also reduces lateral forces during operation on slopes, for increased riding comfort and improved mowing quality.

    As an alternative to ACTIVE FLOAT hydropneumatic suspension, adjustable spring suspension is also available.

  • The right setting – always.

    A single-acting spool valve allows the suspension pressure to be adjusted according to the conditions from the comfort of the cab, even while you are mowing. The current set value is displayed on an easily visible pressure gauge. The general rule is to set the suspension as high as possible, and limit the load to the required minimum. Maximum suspension of the mower unit is particularly recommended when mowing at field edges, so that it literally "floats" over uneven ground.

DISCO disc mowers


Conditioner mowers can be used to significantly reduce wilting and drying time, for effective use of very short harvesting windows. You also save on the time required for crop turning operations.

DISCO disc mowers

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 mown 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.

DISCO disc mowers

Leafy crops such as alfalfa call for protective conditioning. The aim is to crush the stalks without destroying the leaves and 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-loading mechanism, which also protects the rollers from foreign objects. Adjustable swathing plates allow swath formation as desired.
