Implement and method for preparing and maintaining dirt arena footing

Tue, 03 Feb 2015 08:00:00 EST

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.



Soil aerator

Tue, 03 Feb 2015 08:00:00 EST

The aerator rollers project below the frame for rolling engagement with the ground and are located in tandem relation relative to the direction of travel. Each aerator roller has teeth that penetrate the ground surface. The formations on each aerator roller are spaced apart from one another circumferentially around and longitudinally along the roller. Formations on one aerator roller are offset from those on the other roller permitting overlap of same. The aerator rollers are interconnected in drive and driven relation to rotate in a predetermined ratio. A hopper mounted on the frame dispenses seeds, fertilizer or the like. A rear depth control roller assembly using one or more rollers or wheels is pivotally mounted on the frame and can be brought into rolling engagement with the ground to control the depth of penetration of the formations of the aerator rollers into the ground.
