ABSTRACT:
A tree harvesting cable saw includes an elongated flexible cable that has a plurality of tubular cutting links located at spaced intervals thereon with reversible drive means for driving the cable saw in either direction of its length. Each cutting link has an axial opening for receiving the cable and a continuous cutting edge on each end extending circumferentially around the entire cable and being spaced therefrom so that the cable can be driven in either direction and sever a tree. The cable saw is supported on a frame through a drive pulley and a driven pulley and is driven by a reversible motor. Preferably, the frame is movable between positions so that the cable saw can be forced through a standing tree to sever the tree adjacent its base.
