  • Patent number: 6672568
    Abstract: A winch assembly for use with a tractor having a power take off (“PTO”) includes a winch framework releasably coupled to a rear portion of the tractor. The winch framework does not inhibit connection of an implement to a three point or drawbar hitch of the tractor. A winch having a cable reel is mounted in the winch framework and coupled to the PTO such that the cable-reel may unwind or retract a cable upon PTO operation. The winch framework may be released from the rear portion of the tractor and coupled to a storage frame mounted elsewhere on the tractor when the winch is not in use. While the winch may be connected to the PTO and used without uncoupling an implement from the tractor, the winch must be removed in order to actively couple the implement to the PTO.
