ABSTRACT:
Hitch for interconnecting a tractor to a towed implement such as a sprayer, operated by a power takeoff (PTO) of the tractor. The hitch has a turning axis located close to the front of the implement, and a universal joint in the PTO shall be in vertical alignment with the turning axis. The towed implement thus more nearly tracks the tractor in turn, and the universal joint undergoes less vibration and thrust loading during turns.
