ABSTRACT:
A trailer hitch which will resist fishtailing and increase stability of the towing vehicle-trailer combination is mounted at the rear of the towing vehicle. The hitch includes a pivot connector, such as a ball, which receives the mating end of a tongue extending from the trailer to be towed. However, the rotation of the trailer about the pivot connector is resisted, but not prevented, and the trailer tongue is biased to a preset position with respect to the pivot connector. The trailer hitch can provide limited lateral movement of the pivot connector to move the pivot point forwardly of the rear of the towing vehicle. The resistance to pivoting of the trailer with respect to the pivot connector results first in lateral movement of the pivot connector before resisted pivoting about the pivot connector. Lateral movement of the connector can be promoted during certain conditions and resisted during other conditions.
