ABSTRACT:
A combine (11) is provided with a feed reverser mechanism (81) to drive a pair of feeder conveyors (23, 24) and a header conveyor auger (46) in reverse when the operator detects a jammed condition in the feeder conveyors or auger. The reversing mechanism (81) includes a hydraulic drive motor (92), a wrap spring clutch (93) and a hydraulic actuator (142), which automatically increases the tension on a drive belt (68) when the conveyors (23, 24) and auger (46) are driven in a reverse direction by the hydraulic motor (92). A pump relief valve (191) prevents delivery of excessive torque to the conveyors (23, 24) and auger (46) during a feed reversing operation.
