Abstract: A support frame equipped with shoulder straps is provided for support from the back of a hunter and a combined motor and winch assembly including a rotary winding member driven from the motor is supported from the frame. The motor and winch assembly projects outwardly of the side of the frame opposite from the side thereof which opposes the back of the person over whose shoulders the shoulder straps pass and the combined motor and winch assembly is supported from a base plate removably supported from the frame. The base plate includes fair lead structure for guiding the free end of an elongated flexible tension member wound on the rotary winding member and the side of the plate remote from the fair lead structure includes anchor structure spaced therealong on a line generally normal to a line extending between the winding member and the fair lead structure. The anchor means is of a construction enabling the opposite ends of a ground anchored bridle to be anchored relative thereto.
