The new OPTIDISC ELITE cutter bar was developed with farmers. Variable spacing between the discs, large overlap zones and the reduced angle of the OPTIDISC cutter bar will provide you with the quality you need. FC 1030 TRIPLES are equipped with this cutter bar and its latest upgrades that guarantee a clean cut at all times. The OPTIDISC ELITE cutter bar includes exclusive features: The overlap zone is almost doubled resulting in better cutting quality in damp sticky ground (or with mole hills), in heavy and laying crops, and in plant cover harvested at the end of autumn.
A smaller pitch angle: this prevents the undulating cut which is typical with close mowing. It also stimulates homogeneous and faster regrowth and makes it easier to adjust the machines that follow.
New disc bearings with exclusive shape and attachment which hold the knives firmly in place in the event of impact while granting 360° rotational freedom.
Earth can build up in front of a cutter bar on hilly plots or in wet and sticky conditions, but not with the OPTIDISC ELITE cutter bar! It has specially designed skids to improve sliding and preserve the sward. Another advantage for forage quality, especially in difficult conditions.
The mower unit is suspended from its centre of gravity.
It has a central pivot point that ensures stability and smooth running, even on the most uneven terrain. Ground contouring is perfect, even at high speeds. Grass stubble is protected and impurities are kept to a minimum. GMD 1011 LIFT-CONTROL mowing units cut at a constant height and follow ground contours almost perfectly, as ensured by the following features:
Unit with pendulum-type articulation,
31° angular offset.
Impressive figures show that KUHN has done everything to improve the quality of your forage!
Road travel at high speeds is the norm today. The GMD 4011 and 4411 mowers are equipped with hydro-pneumatic suspension that makes driving even smoother and more comfortable. It dampens shocks caused by uneven roads for improved stability and driving control. This function is also very practical for headland turns.
No farmer can allow their mower to get damaged mid-season by hitting an obstacle or a wrong manoeuvre. These mowers are equipped with an active system that ensures constant ground pressure, up to an angle of 11°. Should the unit come into contact with an obstacle, ground pressure is reduced and the mower unit pivots up to 25 degrees to the rear and passes over the obstacle. The active Non-Stop breakaway system is also effective when the cutter bar is impacted on the left as the arm’s pivot point is far enough away from the first discs (A). The mower unit returns to its initial work position automatically with the NON-STOP system. The suspension and NON-STOP safety system combination of this machine is unique in the market.
In order to lengthen the machine’s service life, shock absorbers are integrated in between the cutter bar and chassis. The structure of the machine is less affected by impacts, especially when working at fast forward speeds.
You will waste no time on maintenance.
The OPTIDISC cutter bar is an excellent example of added value created through the close collaboration between manufacturer and farmer. It is a solution that is totally adapted to operations and will save you time:
Maintenance is kept down, and is occasionally necessary for the drive system and the pivot points.
Ground pressure is quick and easy to adjust. It is adjusted by modifying hydraulic pressure in the suspension circuit. It takes just a few seconds and no tools are required.
