A dumping device is disclosed comprising a container rotatably connected to a support structure, so that the axis of rotation of the container is rearward and/or below the center of gravity of the container. A releasable stop prevents the container from rotating forward. At least one actuator is provided which exerts a force forward and above the center of gravity of the container, whereby the speed of rotation of the container may be controlled and the container may be maneuvered between its upright and dumping positions.
