Abstract
A stump grinding device includes a wheel having an outer peripheral edge in which a plurality of recesses are formed. Disposed in each recess is a plurality of cutting units each including a block affixed to a floor of the recess, and a bit mounted in the block. Each bit includes a hard tip disposed at a front end thereof. The bits of some of the peripheral cutting units are rotatable relative to their respective blocks, with the hard tips thereof being generally pointed. The bits of others of the peripheral cutting units are non-rotatable to their respective blocks, with the hard tips thereof forming elongated cutting edges. The peripheral cutting units are spaced from leading and trailing ends of the respective recesses to provide spaces for the passage of cuttings.
