The conical body ensures fast unloading. GSV40 is equipped with a strong bumper. When the trailer is working in the field, the lock bolts can be removed so the bumper can turn freely in/out.The unloading is done by 2 Kohlswa chains.
The chains are driven hydraulically by a center placed gearbox.
The placement of the gearbox reduces the load on the axle.
The unloading time is depending on the quantity of oil supplied by the tractor and of the material structure, but generally the speed of loading varies from 40 – 50 seconds.
