A receiver hitch for a tow vehicle comprises a tubular receiver located centrally of the receiver hitch having a receiver opening facing outwardly of the tow vehicle. Hitch pin openings are located in opposing side-walls of the tubular receiver having a common axis and configured to receive a hitch pin. A detection device, for detection of the hitch pin, is located about an outer portion of the tubular receiver and includes hitch pin openings that are located in opposing side-walls and have the common axis of the hitch pin openings in the tubular receiver. Electrical contacts at the hitch pin openings in the detection device are in communication with an electrical circuit of the tow vehicle. The hitch pin operates to close the electrical circuit upon insertion into the openings in the detection device and the tubular receiver and contact with the electrical contacts.

A king pin adaptor is provided for allowing a king pin, intended to connect to a fifth wheel hitch, to be attachable to a ball hitch assembly. A hitch assembly is provided having a plurality of vertical and longitudinal positions for securing a ball member to allow for greater flexibility in attaching to various towed structures. The king pin adaptor and hitch assembly may be used alone or together as components of a towing system for towing a trailer with a king pin or ball mount.

A hitch pin assembly includes a hitch pin, housing and shoulder bushing. The housing removably connects to the bushing when the bushing is seated in the aperture of a receiver tube. When the housing is so connected a plunger of the housing extends through the bushing and projects into the receiver tube. When the shank is inserted into the receiver tube the plunger tip catches the aperture of the shank, holding the shank in a position in which the pin-receiving apertures on the receiver tube and shank are aligned. The hitch pin is then inserted from one side of the receiver tube and into the bushing. A plunger in the housing translates along a projection in a track of the plunger to reveal the projection to the hitch pin tip and place it into position for engagement with the inserted hitch pin. The engagement holds the shank and eliminates rattling.

A transport adapter connectable to a wheeled log arch so that the log arch may be easily mounted in a vertical, wheels-off-the-ground position on a vehicle hitch receiver for transport to a remote work site. The invention also includes the method for using the transport adapter to mount and transport the adapter-equipped log arch on the vehicle hitch receiver.
