A tree delimbing device having a self-aligning cutter head for delimbing a tree stem which is mounted on a frame by a rotational and pivotal support. A substantially inelastic flexible member connects the cutter head to the frame to limit movement of the cutter head. A medial portion of the flexible member is connected to a fluid cylinder so as to urge the cutter head toward a centered position. An accumulator may be provided for regulating the pressure of the fluid in the cylinder. The positioning of the fluid cylinder may be adjustable. A tree stem diameter measuring device having a sliding position indicator may also be provided. A tree stem detector may also be included to sense the presence of a tree stem placed within the cutter head for automatically closing and opening the blades around the stem. A removable mount for the cutter head is also included.
