A grain bin stirring apparatus with a horizontal support member for radially reciprocating down augers, said support member rotating in an arcuate path around the bin wherein the center-most reciprocating auger travels twice as far radially as the other augers through a cable and pulley arrangement. The down augers are caused to move radially by a pivoting link which transmits a programmed extent and speed of motion and the power source is geared to drive both the auger carriage units radially and the support member in an arcuate path.
