Abstract
A high speed harvester cutting chain has increased cutter height to provide an increased space for removal of the cut material from the saw kerf. The increased height of the cutter links eliminates the compacting of the material cut away by the cutter links between the saw chain and the base of the saw kerf. The foot of the cutter links are flared outward to contact the guide bar rails at a different position than the tie straps to increase the wear life of the guide bar and saw chain.
