The compact design of the GMD 1021 F range is ideally adapted to smaller sized tractors or alpine tractors. These machines can be coupled to standard tractors as well as specialist tractors for sloping terrain. AEBI or REFORM as their weight is limited to 575 kg and 635 kg respectivley. The machine’s floatation is ensured by 2 springs or the suspension integrated into the tractor linkage. The pendulum-type articulation reaches a travel range of +/- 8° for adequate ground following.
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:
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 cutter bar has been designed to cope well with obstacles. Being equipped with the PROTECTADRIVE safety system, in the event of a violent impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing thanks to a carefully dimensioned shear groove. Therefore the gear wheels are protected. In less than 15 minutes, the machine can back up and running with a low repair cost.
KUHN advantage: Disc-bearing stations are attached by long bolts that pass through the entire cutter bar. This eliminates any risk of the mounts being torn out of the cutter bar in the event of an impact. Top-of-the-range components strengthen the centre piece of the cutter bar:
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.
The mowers are fitted as standard with a FAST-FIT quick release knife attachment. A powerful leaf spring ensures a constant pressure on the knife’s attachement for increased safety. You only need a few minutes to change a knife. Note that the knife is free to rotate around 360°. A removable knife box makes knife replacement on the OPTIDISC cutter bar easier
To avoid damage during mowing, around the edge of the fields or along trees, the outer FLEXPROTECT guard bends and then returns to its initial shape. This design avoids additional repair costs. Unfolding of the guards is easily done manually or can optionally be done hydraulically
Machine uncoupling, coupling and cleaning are all easily carried out and are perfectly in line with the modern style of the machine.
Weather windows are often very short in hilly areas. For fast forage harvesting, you must maximise your chances. Couple the TC 320 conditioner at the rear in combination with a front mounted GMD 1021 F mower to achieve your goals as quickly as possible.
