ABSTRACT:
Disclosed is a self-aligning auger drive assembly. The assembly includes a hopper with an auger supported therein. A shaft is connected to and extends from the auger externally from the hopper. A coupling is associated with the shaft and is operatively associated with a biasing device which creates an engaging force to promote engagement of the coupling with a motor assembly driver. A portion of the coupling defines a recess which receives at least a portion of the driver as the driver is rotated.
