A dome-shaped enclosure slopes evenly away from the wheel rim supporting surface toward the ground to define an open interior. A hydraulic power unit and hydraulic motor are contained within the open interior of the base. The hydraulic motor has an output shaft which terminates in a coupling for a tool driving extension. The output shaft is arranged in the base interior generally perpendicular to the plane of the rim supporting surface. The length of the shaft is selected so that the coupling does not extend above the plane of the rim supporting surface. | |
