A device (10) for collecting debris from a ground surface (18). A flexible generally planar member (17) has openings (16) therethrough. When the device is laid on and forwardly moved over the ground surface (18) debris on the ground surface passes upwardly through the openings onto collection surfaces (25) of the device. The device has transversely extending barriers (67) positioned whereby, debris passing upwardly through the openings (16) passes upwardly over the barriers (67) and then downwardly to the following collection surface (25). The barriers (67) at least partially obstruct movement of collected debris on the collection surfaces (25) back into the openings (16) under deceleration of the device as it is forwardly moved over the ground surface. |
