ABSTRACT:
A foldable, hollow tubular frame, having a pair of elongated,spaced-apart legs, supports an elongated shaft rotatable on a horizontal axis at about shoulder level, with a conventional motor driven chain saw removably affixed to the shaft outside one end of the frame in cantilever position. An elongated trough extends horizontally of the frame at about waist level and the lower portion of the frame is anchored, or weighted, to avoid tipping. A control lever handle extends from the shaft alongside the saw, within the frame, so that the operator is on the chain side but out of the chain plane.
