ABSTRACT:
A framework mounted on a tractor has separate vertically adjustable feet to support it from the ground at a desired angle of tilt so that a circular saw, slidable on the frame and driven from the tractor, can be moved downwardly and forwardly to sever a tree along a slanting plane below ground level. The frame has a member engageable with a side of the tree to resist the tendency of the frame to move laterally due to reaction from the cutting load on the saw. A hydraulic motor advances the saw while the tractor remains stationary.
