Auxiliary drive for combine augers for cleanout

摘要

An auxiliary rotary drive for at least one auger that in normal operation is rotatable to transport grain from a grain tank of a harvesting apparatus. The auxiliary rotary drive is configured to rotate the at least one auger during cleanout to assist air nozzles or other means to remove residual grain or residue from the harvesting apparatus. The auxiliary rotary drive can be arranged to transfer power to the auger via a clutch arrangement arranged between the auxiliary rotary drive and the auger. The auxiliary rotary drive turns the auger at a speed slower than a normal operating speed of the auger.
