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 conveyor or auger has a folding outer section which projects upwardly and forwardly and laterally outwardly from the container. The auger has a pivotal discharge spout and 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 length of the semi-trailer.
