Abstract
The improved power hitch of the present invention includes a first cylinder 10 has an extension 9 pivotably mounted at 54 on a transverse cylindrical pin 54 extending between vertical legs 50 and 51 to allow vertical movement, and on a vertical pin 56 to allow limited horizontal movement. Cylinder 10 receives a piston rod 13 extending outwardly therefrom which receives a universal hitch receiver 11. A second cylinder 60 is also mounted on transversely spaced vertical legs 50, 51 at 62.
