ABSTRACT OF THE DISCLOSURE To automatically hitch a trailer to a motor vehicle, a first hitch section is mounted on the motor vehicle and a second hitch section is mounted on the forwardly extending tongue of the trailer. The second hitch section comprises a hitch pin vertically mounted on the free end of the trailer's tongue and a guidable member formed of a ground-engaging lower portion and a pyramidal upper portion defining a vertex welded to the lower end of the hitch pin. The pyramidal upper portion is formed with a V-shaped recess that slides on a ramp of the first hitch section to guide the hitch pin toward a mechanism capable of detachably connecting the hitch pin to the first hitch section. The pyramidal configuration enables easy adjustment of the second hitch section to most of the trailer tongues. The ground-engaging portion may include two legs normally placed into a ground-engaging position but mounted on the guidable member for pivoting when they hit the ground while the vehicle is moving. An helicoidal spring is installed between a point of the legs distant from their pivotal connection and a point of the tongue distant from the tongue's free end to return the legs to their ground- engaging position following pivoting thereof.
