The complete freedom of movement provided by the centre pivot mounting of the belt units ensures constant weight alleviation over the entire working width at the same time as providing the basis for three dimensional ground tracking. The ingenious design of the boom reacts in a split second to any bumps in the ground. At the same time, the hydraulic weight alleviation of the two booms ensures a low contact pressure of the two belt units. This means:
Lower tension on the frame of the merger
Maximum soil conservation
The hydraulic weight alleviation system is adjusted using a double-acting spool valve. A pressure gauge for reading the ground pressure is integrated into the mounting frame.
Best ground tracking
1 Hydraulic cylinder on boom
2 Pivot mounting for transverse freedom of movement
3 Guide arm for controlling inclination
4 Hydraulic weight alleviation
5 Stabiliser cylinder for transverse movement
6 Stabiliser cylinder for adjusting inclination
The hydraulic cylinder on the boom lowers the belt unit to operate in the floating position for vertical ground tracking. This provides a vertical freedom of movement ofn +475 mm / - 195 mm.
The pivot mounting ensures an enormous freedom of movement at right angles to the direction of travel. Together with the up and down movements of the boom, an enormous transverse freedom of movement of +30 ° / -13 ° is achieved.
At the headland, the belt unit is locked by a hydraulic cylinder to prevent it from swinging out.
The low-slung linkage between the upper pivot axis and the lower hydraulic arm ensures lightning-fast inclination adjustment in the direction of travel.
The cross conveyor belts can tilt upwards by 11,5 ° in the direction of travel when approaching bumps. This prevents the pick-up tines from scraping the ground.
At headlands, the high ground clearance guarantees that even large swaths can be driven over without damaging them.
530 mm in the side swath position
580 mm in the centre swath position
To achieve this clearance, the booms are raised vertically and the pick-up is also tilted back. The full clearance height is reached quickly to enable fast turning manoeuvres.
Raising the belt units vertically means that they are not split while in side swath mode - so there is no risk of forage falling to the ground.
We also provide you with an individual belt lifting system with electrical preselect as standard for raking in centre-swath mode headlands and field borders that only need one belt width.
