The GSV40 and GSV58 are equipped with a powerful bumper. When working in the field, the locking bolts can be removed so that the bumper can freely swing in / out, as alternatively, hydraulic bumper can be supplied which follows the tailgate. The unloading takes place with 2 Kohlswa bottom chains. The chains are driven hydraulically by a center gearbox. This location halves the axle load. The unloading time is dependent on the amount of oil supplied by the tractor and the structure of the cut material, but in general, the reading time varies from 40 to 50 seconds.
