ABSTRACT:
For use in landmine clearing, a hitch system providing backup with anti-jack knife and anti-dive, the system includes a hitch assembly and a roller assembly. The hitch assembly has a hinge axis housing containing a hinge shaft and a connector shaft housing containing a stop block having a first side that engages a flat region on the hinge shaft and a second side that engages a biasing spring that is held in the connector shaft housing using an end cap. The roller assembly includes a roller frame that is rigidly mechanically coupled to the hinge shaft. The biasing spring is selected to provide a compressive bias to the stop block such that the roller assembly selective rotates about the hinge axis housing when the roller assembly is subjected to a landmine detonation, and such that rotation of the hinge shaft is prevented during normal forward, reverse, and turning maneuvers.
