Abstract
A wheel supported grain wagon includes a container with sloping side walls extending to an incline bottom wall, and a gravity discharge opening is formed within one of the side walls adjacent the bottom wall. A door panel is supported by tracks for movement between an upper open position and a lower close position covering the opening. A grain discharge chute extends from the opening and has opposite side walls connected by a bottom wall. The chute is adjustably supported by a pair of horizontally aligned pivot pins projecting into corresponding slots within a pair of side support brackets secured to the container. The slots extend generally perpendicular to the side wall and have longitudinally spaced bottom notches which selectively receive the pivot pins in response to manually lifting and shifting the discharge chute for selectively positioning the outer edge of the discharge chute at different elevations.
