Abstract: A trailer having a hitch assembly, intended to be used with a receiver on the towing vehicle, enables the vehicle/trailer pair to back up easily by locking the trailer's orientation relative to the towing vehicle. The vertical pivot axis (yaw) may be locked while the lateral (pitch) and longitudinal axes (roll) may remain free to rotate to allow for bumps and dips in the road. Furthermore a steerable suspension can be provided for many embodiments such as with an actuator receiving a signal from the back up wiring of the vehicle to change the mechanical constraints of the steering system upon receipt of the signal (such as to lock the position of a first tie rod connecting the wheels to the frame while freeing another, and possibly altering the angle of the wheels relative to the frame in the process). Meanwhile a toe-in effect of the wheels can be achieved by using multiple tie rods with a front tie rod bent rearwardly towards a rear tie rod.

Abstract: A trailer hitch facilitating proper alignment and connection to the hitch coupler of a trailer. The trailer hitch includes a tow bar assembly and a throat having spaced parallel top and floor panels generally equal in spacing to a vertical thickness of the tow bar and rearwardly diverging side panels. The front of the throat is connected or connectable to an elongated tubular extension or receiver and is sized to be slidably carried within the throat assembly. A slide bar is carried between the tow bar and the throat and includes a stop which limits the distance the tow bar may be extended rearwardly from the throat and, when in the fully or a partially extended position, is movable side-to-side to facilitate proper coupling alignment between the hitch ball and a hitch coupling of a trailer.

Abstract: A hitch extension apparatus for attaching an implement with a pto driven drive shaft having front and rear universal joints to a tractor drawbar. The apparatus comprises a first member adapted for attachment to the tractor drawbar by insertion of a drawbar pin through the drawbar such that the first member is fixed with respect to the drawbar. An extension member is pivotally attached to the first member about a horizontal pitch axis oriented perpendicular to the travel direction, and about a horizontal roll axis oriented parallel to the operating travel direction. The extension member defines a pivotal attachment location rearward of the draw pin hole adapted for pivotal attachment of the implement about a vertical yaw axis located equidistant from the front and rear universal joints when the drive shaft is connected to the tractor power take off. The pitch axis can be located forward of the yaw axis, and forward of the draw pin hole in order to reduce bending forces on the drawbar.
