A lock is operative to lock the pivot arm in a fixed position with respect to the tow arm. An outer castor wheel is pivotally attached to the apparatus to support the outer end of the lateral, and an inner castor wheel is pivotally attached to support the inner end of the tow arm. An implement hitch is attached to an outer portion of the tow arm between the outer and inner castor wheels and is adapted for attachment of an implement to be towed behind the tow arm. The apparatus is adapted to prevent lateral movement of the implement with respect to the tow arm.

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.

Abstract: Hitch structure for connecting first and second implements for operation side-by-side in the field, and one directly behind the other for transport. A freely rockable swing hitch has a forward end connected to one side of the first implement frame for pivoting less than 180.degree. about an upright axis located inwardly from the side. A latch on the swing hitch mates with a frame-mounted rear bracket to secure the hitch in the transport position. The same latch secures the swing hitch to a bracket on the forward towing hitch when the swing hitch and towing hitch are in the field-working position. A sliding tubular member and two-position latch selectively secure the towing hitch in either a central transport position or an offset field-working position. Both latches have release levers for changing from one position to the other, and the latches automatically lock in the new position when the desired position is attained.

Abstract: Lift arms on a gang of implements support transport wheels which are movable from a raised field-working position to a lowered endwise towing position. Several of the wheels at the forward and aft ends of the towed gang of implements are fitted with castering pivots located adjacent the wheel hubs close to the wheel centerlines to lessen side loading and tire scuffing during turns. The castering wheels include a caster control assembly having at least four functions. First, a lock feature includes a spring-biased pin selectively engageable with the control assembly to secure the wheels in an in-line position to permit easy backing of the implements in the towing configuration. Second, a contact on the implement frame which engages the caster control assembly when the wheels are raised off the ground, cams the caster wheel to a preselected field-working position and prevents rocking of the wheel. Third, a bellevue washer on the caster control assembly limits shimmying of the wheel during transport.

Abstract: An implement hitch assembly serves to aggregate two machines. The machines are echeloned in the working position or in tandem in a transport position when moving from one field to another. The hitch includes a transverse draw bar, connected to a tractor. On the transverse draw bar, provision is made for a pull rod of a front farm machine, which is mounted thereon by a carriage. The hydraulic drive installed on the transverse draw bar is intended for moving the carriage along the transverse draw bar. A lever pivotably connected to the pull rod of the front farm machine carries an arcuate beam coupled therewith at the front end thereof by a pivot. The rear end of the arcuate beam rests on a support wheel with a suspension. On the vertical axis of the suspension there is mounted a clevis of a rear farm machine. The hydraulic drive connected with the pull rod of the front farm machine moves the latter along as it transfers both machines to one of the positions hereinabove identified.
