Abstract
A power operated, draw bar mounted hitch for connection to the tongue of a farm implement has a fixed draw pin and a bottom hammer strap that engages under the tongue and raises the tongue onto the draw bar, where it is captured in place between the bottom hammer strap and a top hammer strap mounted on the draw bar. The hitch has an automatic self locking feature that automatically locks the hitch when it reaches the engaged position.
