ABSTRACT:
A tree stump cutter than enables the removal of tree stumps, after felling of trees, to at least below ground level, includes at least one pair of circular cutting blades rotatably mounted on a support frame. The frame can be coupled to a tractor in a configuration in which the blades, driven by hydraulic motors, can cut off tree stumps below ground level by being displaced across the tree stumps by the tractor. The blades are rotatable about parallel axes and the blades of at least one pair are spaced apart by approximately the sum of their radii, thus permitting rotation in substantially the same plane.
