A stump cutter tooth held by a pocket member, which has first and second edge, and the pocket member being operatively attached to a driven wheel, which has opposite first and second side surfaces. The stump cutter tooth includes an elongate tooth body that has an axial forward end. A first hard region is at the axial forward end of the tooth body and defines at least one distinct cutting edge that has an orientation to engage the stump during operation. A second hard region is at the axial forward end of the tooth body and is distinct from the first hard region. The second hard region provides protection to at least a portion of the pocket member.
