Abstract
A multiple implement to tractor hitch assembly. A horizontally disposed elongated first beam is horizontally curved and connected intermediate its ends by a tongue with a tractor drawbar for horizontal pivoting movement of the first beam about the vertical axis of its tongue connection for positioning implements when connected with respective parallel end portions of the beam in a tandem or laterally spaced soil working position by a power cylinder extending between the first beam and the tongue. A second substantially identical beam is hingedly connected in tandem by one of its ends to the trailing end of the first beam for vertical pivoting movement of the beams about the horizontal hinge connection. An agricultural implement is connected with the beams at their hinged connection and with the respective other end of the respective beam.
