ABSTRACT:
Tree stump grinding teeth for use in tree stump grinding wheel assemblies and tree stump grinding wheel assemblies that include one or more such grinding teeth. In the preferred embodiment of the invention, the grinding tooth includes a mounting base having a substantially flat surface from which a plurality of cleats project.

The resilient impact pad protects the surface of the wheel from impact forces applied to the grinding tooth.
