ABSTRACT:
A stump-grinding apparatus includes a primer mover secured to a frame having a pair of wheels and a handle. A cutting wheel is secured to the prime mover for rotation. At least one cam member is coupled between the wheels and the frame and is operable from the handle to selectively adjust the height between the cutting wheel and the object to be disintegrated. A throttle member is also secured to the handle for selective control of the prime mover. The cutting wheel has a generally disk-shaped element having an outer diameter. At least one cutting tooth having a leading cutting edge and a generally opposite trailing cutting edge is secured to the outer diameter of the disk to define a selected angle between the leading cutting edge and a line parallel to the axis rotation of the cutting wheel. This angular offset permits the cutting wheel to cut a wider kerf, and to impart a slicing action in addition to the chipping action of the teeth.
