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. A steering mechanism located on the caster wheel assembly of the trailing implement and operable from the tractor cab guides the second implement as the swing hitch pivots during conversions.
