Abstract: A hard surface preparation device for use in the removal of membranes, paving materials, flooring, tiles, roofing materials, and other materials from relatively hard surfaces such as concrete. The device includes two frames; a base frame and a second frame pivotally mounted to the base frame. The base frame is coupled to a small tractor by means of mounting brackets. The mounting brackets are bolted or otherwise secured to a moveable, powered mounting plate which is coupled to the hydraulically powered arms of the tractor, thereby permitting the device to be raised or lowered like any other front-end implement used with such a tractor. A motor or power take off from the tractor drives an eccentric shaft mounted on the base frame. A sleeve fits over the eccentric shaft and transforms the elliptical movement of the shaft into a back and forth motion. A blade mounted to the second frame is also coupled to the sleeve and, therefore oscillates when the motor is turned on.
