Abstract

A drive system for a crop processing device and for a crop transport device of a forage harvester, can be operated at least in a first operational mode and in a second operational mode. In the first operational mode, the crop processing device is driven by a first drive power supplying device, and at least part of the drive power is made available to the crop transport device by a second drive power supplying device. The second drive power supplying device is a reversible, variable speed device and is solely coupled to the crop processing device when the drive system is in a second operational mode. In order to prevent a movement of the crop transport device in the second operational mode, in which, e.g., the crop processing device can be worked with a sharpening device, a stop device is suggested that stops the crop transport device in the second operational mode.
