DRIVE SYSTEM FOR A CROP PROCESSING DEVICE AND FOR A CROP TRANSPORT DEVICE OF A HARVESTING MACHINE

摘要

Disclosed is a drive system for a crop processing device and for a croptransport device of a forage harvester, which drive system can be operated atleastin a first operational mode and in a second operational mode. In the firstoperationalmode, the crop processing device is driven by a first drive power supplyingdevice,and at least part of the drive power is made available to the crop transportdevice bya second drive power supplying device. The second drive power supplying deviceisa reversible, variable speed device and is solely coupled to the cropprocessingdevice when the drive system is in a second operational mode. In order toprevent amovement of the crop transport device in the second operational mode, inwhich,e.g., the crop processing device can be worked with a sharpening device, astopdevice is suggested that stops the crop transport device in the secondoperationalmode.
