ABSTRACT:
An adjustable three-point hitch for allowing a user to hydraulically manipulate the rotational position of an implement with respect to a longitudinal axis of the tractor. The inventive device includes a support frame attachable to a front portion of a tractor frame, a pair of lift arms pivotally attached to the support frame, a pair of lifting cylinders fluidly connected in parallel and attached between the support frame and the pair of lift arms, a center arm pivotally attached to the support frame, a tilting arm having a slot pivotally attached to one of the lift arms, an engaging member extending from the opposing lift arm within the slot, and a tilting cylinder attached between the support frame and the tilting arm for manipulating the tilting arm. To adjust the position of the lift arms with respect to one another, the tilting cylinder is extended or retracted until the desired position is reached.
