Abstract: A stump grinding wheel tooth assembly having a mounting block positioned around the periphery of the wheel and a cutting bit attached to the mounting block by a pin passing through a hole in the cutting bit and a corresponding hole in the mounting block and capped by a nut. The mounting block may support multiple cutting bits arranged into a predetermined patterns based on the location of the holes, such as pairs of cutting bits or even a quad formation. The cutting bits may be provided in various geometric configurations, such as round, triangular, square, rectangular, pentagonal, hexagonal, octagonal or decagonal.

Abstract: A stump cutting assembly mounted to a stump cutting wheel. Stump cutting assembly is a stump cutting tooth interconnected to the wheel by a holder or block that is fixed to wheel by welding or other equivalent process, an optional debris deflector and a fastener that interconnects tooth and deflector to holder. As wheel rotates about its axis of rotation, the tooth cuts away at wood or other debris in which it comes into contact through the side to side and/or longitudinal movement of a stump grinder unit.
