A dump vehicle with a positively controlled opening gate is disclosed. The vehicle includes a frame, a dump bed mounted on the frame and having a floor, front and side walls and a rear opening through which material can be discharged from the bed, and a gate having a pair of lateral edges and a lower edge. The gate is pivotally mounted adjacent the rear opening and has a closed position in which the gate blocks the rear opening to prevent discharge from the bed through the rear opening. The vehicle further includes a gate control mechanism connected to the gate. The gate control mechanism is adapted to selectively raise the gate from the closed position to allow metered discharge of material or to release the gate from the closed position so that the gate may pivot away from the rear opening to allow unmetered discharge of material.
