Abstract
A stump-grinding apparatus includes a block having an inner surface and an outer surface. The inner surface is adjacent to a side -of the wheel between the center of wheel and the peripheral edge. The outer surface defines both a groove and a first aperture in the groove. A tooth is received into the groove. The tooth has a first end and a second end spaced from the first end. The second end defines a second aperture that can align with the first aperture. A fastener extends through the first and second aperture to fasten the tooth to the block.
