摘要：
A portable tree stump remover, sufficiently light weight to be hand held by an operator, has an engine-driven cutting device with grinding teeth that rotate through a circular path. The cutting device is mounted to a base element that regulates the penetration depth of the grinding teeth into the tree stump and engages the tree stump when a predetermined penetration depth has been achieved.
