ABSTRACT:
A power sweep for an agricultural grain bin includes a powered belt conveyor adapted to unload the grain when desired. The inboard end of the belt conveyor includes an idler roller which is frictionally coupled to the inner surface of the belt and, through a power transmission, may be actuated, by means of a clutch, to drive a power sweep for cleaning residual grain from the bottom of the storage bin after the belt conveyor has removed the bulk of the grain.
