ABSTRACT Portable, ground breaking tool for restoring ground and gravel surfaces on driving, parking and storage areas. A ground breaking device which mounts under a motor vehicle and moved in a forward or reverse direction by it. Hydraulically raised and lowered, its depth of penetration into the earth is adjustable and it is also transportable while remaining attached to the vehicle. The rotating "star" like designed wheel is the ground breaking portion of the unit. Its "fingers" are forced by the weight of the vehicle, to penetrate the ground surface and cause the ground to loosen due to the rotating motion of the wheel. The tool may be suspended and supported in part by a spring, leaf or coil, that absorbs shocks created by the motion of the star wheel on hard ground.
