ABSTRACT:
In a grain cart equipped with a lower horizontally-disposed input drag auger, a vertically disposed lift auger, and an upper horizontally disposed discharge auger, a unique drive train is used. The lift auger and the discharge auger can be activated independently of the input auger in order to empty their contents on start-up of the grain cart discharge system. By so doing the strain on the drive train is considerably lessened thus permitting very large grain carts to be emptied without damage to the drive train system. A hydraulic cylinder activates a belt-tightener between a drive sheave and a driven sheave. The driven sheave is attached to the axis of the drag auger. When the hydraulic cylinder is extended, pressure exerted on the belt causes the input auger to rotate and to feed the lift and discharge augers.
