ABSTRACT:
A free-swinging cutter for use on a machine adapted to cut and clear brush and trees, including a generally stirrup-shaped member having two opposing sidewalls, a leading face with a cutting edge for cutting, and a rearward face opposite the leading face. The cutter is adapted to be swingably mounted at a point offset from its center of mass so that the cutting edge is disposed below the rearward face to form a relief heel. The invention also includes a method of creating a relief area on a cutter swingably mounted on the rotating drum to improve chip flow, which includes the steps of providing a cutter as described above and swingably mounting the cutter to a drum about an axis offset from the cutter's center of mass so that the cutting edge is disposed below the rearward face when the cutter extends radially from the drum following the rotation of the drum.
