Abstract
A hitch guidance mechanism for an agricultural vehicle having a pair of movable draft links for coupling to an implement and having a pair of brackets attached to the rear end of a frame of the vehicle. The brackets are positioned above and on opposite sides of a PTO shaft which projects from the frame. Pivot arms are pivotally suspended from the brackets. Left and right sway block supports are pivotally coupled to the lower ends of the pivot arms. The sway block supports are rigidly interconnected to each other by a rectangular plate and an adjustable length rod. A pair of sway blocks slidably engage the draft links and are adjustably fixable to the sway block supports. An actuator is coupled between the frame and one of the sway block supports for controlling lateral movement of the sway block supports, the sway blocks and the draft links.
