发明名称 Jack stand for plow hitch
摘要 A jack assembly integrated with a plow hitch assembly includes a horizontally supported, rotatable jack tube and a jack leg extending from the tube, rotatable with the tube between a vertical, deployed position and a retracted position. An actuator has one end attached to the jack assembly and another end forming a handle projecting above the hitch frame, for rotating the jack assembly. The jack leg can be selectively extended and retracted relative to the tube when the jack assembly is deployed. A method embodiment includes lowering the plow to the ground while the hitch frame is mounted to the vehicle; rotating the jack assembly so the jack leg projects toward the ground; extending the jack leg to contact the ground; rigidly supporting the extended jack leg relative to the hitch frame; demounting the hitch frame from the vehicle; and driving the vehicle out of the hitch frame.
