ABSTRACT:
A hitch attaches to a lawn tractor and draws two lawn mowers therebehind. The hitch includes a draw bar solidly mounted to the tractor, and a link for each towed mower, which mowers each include a bracket to the deck thereof. The links include plumbing tees perpendicularly arranged, so that universal joints are formed between the draw bar and the mowers. A third tee is provided at each bracket so that each mower may be individually tilted, as for enabling access to the underside while still ganged to the hitch. The draw bar, links, and third tee are made from readily available plumbing components. The resultant hitch is thus fabricated from readily available components, is durable, uncomplicated, and has wide flexibility in allowing for various attitudes of the mowers. This enables individual mowers to follow the contour of uneven terrain, turn in tight quarters while being towed, and to be temporarily tilted for access to the cutting blade and oil drain cock without requiring disassembly from the hitch.
