Abstract
Abstract A device for picking up material lying on the ground includes a wheeled frame with brushes and/or mowing elements rotatably mounted below the frame to urge material rearwardly. A collecting trough is pivoted at its upper aspect to the device and movable from an operating collecting position to a discharge position. A channel communicates between a pick-up brush and the trough to extend the length of the brush, across the width of the frame to pass material back to the trough. An eccentric is connected to reciprocate a piston that forces the material into the trough through at least one movable flap. The eccentric is driven by a motor which also propels the device.
