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. Where the wheelbarrow conversion to a trailer is intended for heavy loads, a piece of flat iron is attached to the topside 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.

What is claimed is: 1. For attachment of a two-wheeled wheelbarrow to the rear of a towing vehicle with a vertically apertured draw bar, and thereby converting the two-wheeled wheelbarrow into a garden or industrial trailer, a combination comprising: a wheelbarrow having a body with workman's end, dumping end and side walls, a frame including a pair of lower rails with lifting/transporting handles forward of the workman's end, extending and converging from forward of the workmen's end, beneath the body to the dumping end, a toe plate joining the rails at their dumping end and a pair of wheels mounted on an axle supported on the frame; and, a tow bar assembly comprising a bar having a forward end and a rearward end, the forward end having means for attachment to the towing vehicle from below to and through the towing vehicle vertically apertured draw bar and the rearward end having means for attachment about the wheelbarrow axle, the tow bar resting upon the wheelbarrow toe plate during use. 2. The combination of claim 1 including a plate affixed to the rails at the dumping end of the wheelbarrow over the toe plate upon which the bar rests during use. 3. The combination of claim 1 including a pair of grommets for mounting on the wheelbarrow axle for centering the tow bar thereon. 4. For attachment of a two-wheeled wheel barrow to the rear of a towing vehicle with a vertically apertured draw bar, and thereby converting the two-wheeled wheelbarrow into a garden or industrial trailer, a combination comprising: a wheelbarrow having a body with workman's end, dumping end and side walls, a frame including a pair of lower rails with lifting/transporting handles forward of the workman's end, extending and converging from forward of the workmen's end, beneath the body to the dumping end, a toe plate joining the rails at their dumping end and a pair of wheels mounted on an axle supported on the frame; and, a tow bar assembly comprising a bar of channel shaped metal having a forward end and a rearward end, the forward end having a vertical post for attachment to the towing vehicle from below to and through the vertically apertured draw bar and the rearward end having an opening therethrough for attachment about the wheelbarrow axle, the tow bar resting upon the wheelbarrow toe plate during use. 5. The combination of claim 4 including a plate affixed to the rails at the dumping end of the wheelbarrow over the toe plate upon which the bar rests during use. 6. The combination of claim 4 including a pair of grommets for mounting on the wheelbarrow axle for centering the tow bar thereon. 7. For attachment of a two-wheeled wheel barrow to the rear of a towing vehicle with a vertically apertured draw bar, and thereby converting the two-wheeled wheelbarrow into a garden or industrial trailer, a combination comprising: a wheelbarrow having a body with workman's end, dumping end and side walls, a frame including a pair of lower rails with lifting/transporting handles forward of the workman's end, extending and converging from forward of the workmen's end, beneath the body to the dumping end, a toe plate joining the rails at their dumping end and a pair of wheels mounted on an axle supported on the frame; and, a tow bar assembly, comprising a bar of channel shaped metal having a forward end and a rearward end, the forward end having vertical openings and a vertical post secured therein for attachment to the towing vehicle from below to and through the towing vehicle vertically apertured draw bar and the rearward end having horizontal openings therethrough for attachment about the wheelbarrow axle, the tow bar resting upon the wheelbarrow toe plate during use. 8. The combination of claim 7 including a plate affixed to the rails at the dumping end of the wheelbarrow over the toe plate upon which the bar rests during use. 9. The combination of claim 7 including a pair of grommets for mounting on the wheelbarrow axle for centering the tow bar thereon.
