Abstract: A belt tensioning apparatus for use in tensioning a belt driven drive system having a motor and belt driven member. The arrangement provides a mounting member with a belt tensioning member operatively connected thereto for applying adjustable tension to a belt when positioned about the motor and belt driven member. An actuator connected to the belt tensioning member allows for movement of the belt tensioning member. A tension operating zone member operable with the actuator is used to alert a user when belt tension is optimal, requires adjustment or is prohibitive.

Abstract: A terminal elevator drive wheel for a grain bin sweep auger has angled spaced peripheral inward extending blades, which break up compacted grain, drive the auger forward, and pass the grain through an attached elevator housing over a deflector plate to the sweep auger flighting. A reduction drivebox with three double reduction sprocket and chain drives, rotate a drive sprocket axially engaging and rotating the elevator wheel.
