ABSTRACT:
A wheel supported grain wagon includes a box or container with sloping side walls extending to a bottom wall, and a discharge opening is formed within one of the side walls adjacent the bottom wall. An inner metering door or panel and an adjacent outer closure door or panel are supported by parallel spaced dual tracks for movement between lower positions closing the discharge opening and retracted upper open positions. An actuator first raises the outer closure panel to permit grain to flow through a metering passage defined by the bottom edge of the metering panel and to release grain pressure on the metering panel. The metering door is then elevated in response to further elevation of the outer closure panel so that grain flows smoothly under both panels without obstructions.
