A tow bar assembly for converting a two-wheeled wheelbarrow into a garden or industrial type trailer includes a bar of metal box tubing with horizontal holes at the wheelbarrow end and vertical holes at the tractor end. The wheelbarrow end is slid onto the axle of the wheelbarrow, keeping the bar between the tub of the wheelbarrow and its toe plate. Grommets positioned on the axle on either side of the bar center the tow bar assembly on the axle. A threaded post is inserted into the holes in the tractor end of the bar and locked into place by nuts. In use, the handles of the wheelbarrow are raised and the post inserted into the aperture of the tractor's draw bar from the underside of the aperture. The cantilevered weight of the wheelbarrow will keep the wheelbarrow from becoming disengaged from the garden tractor or towing vehicle. The legs of the wheelbarrow are kept off the ground and the trailer-barrow is now ready for use. Especially where the wheelbarrow conversion to a trailer is intended for heavy loads, a piece of flat iron is attached to the top-side of the rails of the wheelbarrow close to its dumping end. In this way, when in use, the tow bar will rest on the flat iron instead of the wheelbarrow's toe bracket. In a preferred embodiment the bar is PVC piping and a piece of flat iron is riveted to the bar, parallel to same so that in use the flat iron rests on the toe plate.
