Abstract
A two-wheeled trailer hitch supporting two three-point hitch mounted implements side-by-side for field operation. The implements are mounted on outriggers which are foldable forwardly to narrow the unit for transport. A pair of rigid diagonal drag links movable fore-and-aft by a cylinder-activated slide block is connected to the outriggers for pivoting them approximately ninety degrees between the field and transport positions. Lift frame structures selectively engage the three-point hitch linkages to raise the implements on the respective outriggers. The lift frame structure is disengaged from the linkages when the implements are lowered for greater flexibility in the field-working position.
