GEARCASE
LONG LIFETIME
ROBUST GEARCASE AND TRANSMISSION
For optimum performance in difficult soil conditions, the robust, self-supporting gearcase design provides a large clearance between the tine holder and gearcase bottom. Large amounts of residues and stones can pass freely without blocking and provides excellent results in mulch conditions.
Robust but less weight.
The gearcase, which is the backbone of the whole machine is extremely rigid against bending and torsional stress. On the H and S series the gearcase is made as a sandwich double bending beam to give additional stability. With this new gearcase and headstock design the weight of the S series is reduced by 15% compared to the former model. There are differences in dimensions between the models, but the headstock is the same on all models and absorbed together width the gearcase all mechanical forces. Special emphasis has been given to reliability. This has been achieved by having a large distance between the conical bearings, hardened gears inside a stable gearcase, precise distance between the gears and the heavy-duty rigid gearcase design. The robust headstock for easy connection to all tractors and combination with heavy seed drills ensures safe working.
