Abstract
Embodiments of the disclosure provide a saw chain having cutter links having a cutting edge on a first end and an opposite second end adapted for riding on or along a rail of a guide bar. First drive links are coupled with the cutter links and are adapted to ride in a groove of a guide bar. The first drive links have a clean out tang sized and shaped to scoop debris from within the groove, and have two first drive link side surfaces on opposite sides thereof adapted to have at least occasional wearing contact with interior side walls of the groove. Second drive links are coupled with the first drive links and the cutter links, and are adapted to ride in the groove of the guide bar. Each second drive link has second drive link side surfaces adapted to have at least occasional wearing contact with the interior side walls of the groove. The second drive link side surfaces have a greater surface area than the first drive link side surfaces, and in some embodiments may be featured rudder links.
