Abstract
An implement is disclosed for smoothing grounds that include at least a compact base having a top surface and a lesser compact footing on top of the base. The implement includes a frame having a front portion, a central portion, a rear portion, and a width. Wheels are mounted for rotation directly to the frame, and tools are carried by the frame for engagement with the ground. The tools include a specially shaped cleaving blade connected to the rear portion of the frame by a tool support, which securely connects the cleaving blade at predetermined heights. The blade has a front shaving edge and a rear compressing edge. The blade extends straight across the width of the frame so as to maximize the drag displaced on the frame during use of the blade. Arrangement of the wheels directly on the frame provides optimal stabilization of the frame during operation of the blade.
