An agricultural machine, comprises a frame, two or more processing members, which are movably attached to the frame, and a drive device which is configured to drive the processing members. The drive device comprises a main drive shaft, two drive sections connected to the main drive shaft, which drive sections are each configured to drive one or more of the two or more processing members, wherein each drive section comprises a drive shaft. The drive device further comprises a protective device which enables a certain angular rotation between the two drive shafts in the case of an overload of one of the two drive shafts, and a coupling brake device which is configured to effect, at the angular rotation between the two drive shafts, a coupling between the other drive shaft and a part of the agricultural machine that is not co-rotatable with the two drive shafts.
Agricultural machine, comprising:
In an agricultural machine having a drive device, a coupling brake device configured to effect, in the case of a defined relative angular rotation between two drive shafts of the drive device as a result of an overload of one of the two drive shafts, a coupling between the other drive shaft and a component which is not co-rotatable with the two drive shafts, in order thus to limit the angular rotation between the two drive shafts.
Method of protecting a drive device for two or more overlapping groups of processing members of an agricultural machine, comprising:
