Abstract
A grain wagon includes a wheel supported frame on which is mounted a hopper or container for receiving grain, and the wagon is pulled by a tow vehicle or tractor. An inclined discharge auger conveyor has an outer section which folds between a stored position and an operating position projecting upwardly and forwardly and laterally outwardly from the container. The outer auger section has a pivotal discharge spout with a pivotal internal baffle, and the spout is actuated by a double acting hydraulic cylinder controllable through hydraulic lines from the cab of the tractor so that the tractor operator may fully load and “top off” the grain within an adjacent semi-trailer as the tractor operator pulls the wagon along the side of the semi-trailer. In one embodiment, the outer section of the auger conveyor has an outer telescopic housing extension which carries the discharge spout and extends and retracts automatically with folding of the outer auger conveyor section.
