Abstract: A plow hitch assembly comprising a hitch frame, a lift frame pivotally connected to the back end of the hitch frame, and a back end effector for mounting to a vehicle. The back end effector has an associated latching device and a distinctly actuated device for locking the latch. A stop surface is situated on the latch, and a selectively displaceable lock block supported by the lift frame, abuts the stop surface to prevent rotation of the latch. Each of two uniformly rectangular mounting arms extends from the back of the lift frame, preferably with a leading end having a pair of vertically oriented rollers at the corners. Each guide has a rectangular main channel conforming in cross section with the arm when the arm is fully inserted into the channel and an entry that is larger in cross sectional area than the front of the arm.
