ABSTRACT:
A stump grinding disk includes a metallic wheel defining an axis of rotation and including a pair of side surfaces and a circumferential outer edge surface. The outer edge surface includes a plurality of circumferentially spaced recesses. Each recess extends axially completely through the disk. A plurality of side cutting elements are mounted on each side surface. A plurality of outer peripheral cutters are spaced circumferentially apart around the outer edge surface. Wear strips are mounted in respective recesses. Each wear strip includes a metal matrix in which hard particles are disposed. Each wear strip defines a radially inner surface affixed to the wheel, and a radially outer surface arranged substantially flush with adjacent portions of the outer edge surface.
