Kuhn has launched two mower-conditioners for use in delicate crops like lucerne or alfalfa, where leaf loss can be a major problem if conditioning is done by traditional flail type designs.
The range is extensive: GMD 2811, 3111, 3511, 4011 and 4411 models, with respective working widths of 2.67, 3.10, 3.50, 3.95 and 4.35m.
The Lift Control suspension combines floatation, a pendulum-type articulation and an active non-stop safety without the need for an adjustment tool.
These features combine to reduce lost time with the break-back system and the machine’s inherent ability to rise upward and move rearwards should it encounter an obstacle.
Also, the machine’s service life is extended, and skid wear and fuel consumption are reduced.
The machines have higher clearance in headland turns.
A larger machine offset range allows fitment to larger tractors to match up with front mounted mowers.
A simplified tractor coupling means lower links no longer need adjustment to compensate for the weight of the mower, and automated setting of a 45-50mm cutting height when the machine is moved into the working position.
The GMD 4011 and 4411 mowing units are fitted with suspension for transport and headland turning, and for greater safety and comfort while driving on rough terrain.
The new GMDs are, as with former models, equipped with the maintenance-free Optidisc cutter bar in which the discs are spaced to ensure quality mowing and reliable forage ejection.
The cutter bar is coupled to the main frame with rubber mounts that absorb vibrations, and the maker’s Protectadrive prevents damage in the event of hitting an obstacle.
