ABSTRACT:
An improved drive arrrangement in grain stirrers of the type including a sweep arm suspended between a track along the bin sidewall and a pivot support toward the bin's center. The sweep arm includes a laterally extending support element extending from the support frame, being selectively rotatable or counterrotatable, and a sweep drive unit being selectively rotatable independently of the support element and including a drive wheel engaging the bin track. Stirring augers depend from the laterally extending sweep arm, and are adapted for radial movement along the sweep arm in either direction in accordance with rotation and counter-rotation of the support element. An automatically selective reversing drive system, comprising opposed one-way clutches, interconnects the support element and the drive wheel whereby the sweep arm is driven in one direction around the bin in response to both such rotation and such counterrotation of the support element.
