ABSTRACT:
A multi-purpose log-handling tool for attachment to the three-point hitch of a tractor or other vehicle includes a boom and an inverted U-shaped frame containing a number of apertures to which accessory tools may be attached. The boom and the frame are connected to the tractor and at one of the apertures to permit the outer end of the boom to be lowered and raised by an operator controlling one or more hydraulic pistons. The apertures are preferably longitudinally arranged along a flange affixed to the bottom of the boom. Multiple apertures permit the simultaneous use of more than one tool, which might include logging tongs, chains, or winches. A flexible assembly for coupling the boom to the hydraulic piston accommodates for skewing action as a log is dragged and thereby reduces potential for damage to the log-handling tool.
