A wheeled hand truck adapted to carry lightweight three-point tractor hitch equipment. The hand truck has a frame made from two vertical rails, a handle, and some transverse ribs. An axle and a pair of wheels serve as the pivot point of the frame when the device is lifting objects. An extensible, upper support arm has a near end that is pivotally mounted to an upper rib. The support arm pivots up and down along a vertical plane, and has an apertured far end for attaching to the upper point of a three-point hitch connection. The hand truck also has a pair of lower lift arms that pivot from side to side along a substantially horizontal plane so as to be adjustably connectable to the lower two points of a three-point hitch connection.
