Abstract
There is disclosed herein a machine for removing coatings from uneven surfaces such as concrete and the like. The machine includes a power system for driving a pair of cutter head assemblies. The cutter head assemblies are rotated in opposite directions to help stabilize the machine and to throw the cuttings out of the way. Each cutter head assembly has a cutter head with a plurality of peripheral sides or facets and cutter bars are spring loaded thereon to allow cutting tools held by the cutter bars to effectively float on the concrete surface and follow uneven sections of the surface. The cutter head assemblies are mounted on the machine so that they can tilt forward and backward and from side to side to facilitate the cutter head assemblies following uneven surfaces. In one embodiment a plurality of cutter bars are pivotally mounted to the peripheral faces of each cutter head, and in another embodiment cutter pads with diamond bits are spring loaded and extend from the bottom surface of the cutter head.
