发明名称 Method and apparatus to fell a tree
摘要 A method and apparatus to fell a tree is disclosed. A vehicle mountable felling head includes a circular saw mounted to the felling head. A guard overlays the circular saw as a safety measure. The guard has a first portion which is fixed. The fixed portion of the guard has an opening exposing a first arcuate portion of the saw. The guard also has a second, movable portion which overlays a second arcuate portion of the circular saw. The second portion of the guard may be raised to expose a second arcuate portion of the circular saw to cut a slot in one side of a tree with the cut being completed by the first arcuate portion thereby allowing a tree greater in diameter than the radius of the circular saw to be severed.
