ABSTRACT:
A self-propelled forage harvester includes an overload clutch inserted into the driveline of a crop conveying element of crop pick-up arrangement of the harvesting machine. The overload clutch generates acoustic and/or mechanical vibrations when a defined torque is exceeded, and a knock sensor is provided for sensing when the overload clutch is operating in an overloaded condition. The knock sensor sends a signal to a control arrangement including a signal processor which recognizes a vibration pattern representative of an overload, and in response to such a pattern, sends a control signal for shutting off the drive to various driven components of the harvester.
