<p>A trailer hitch which has a head demountably securable to a rearwardly extending mounting bar of the vehicle. The head permits substantial vertical adjustments before its installation to obtain standard spacings between it and the ground and includes laterally protruding flanges that mount identical load equalizing spring bar connectors. The connectors are retained to the flanges while they pivot about upright axes over a predetermined sector and can be removed from the head when they pivot through other sectors. The pivot axes are slightly inclined from the vertical. The spring bars are longitudinally tapered, retained in rearwardly directed openings in the connectors and include tensioning chains at their free aft ends secured to a retention member mounted to a forwardly extending trailer bar of the trailer. A chain engaging lever enables the simultaneous tensioning of the chain and its connection to or release from the chain retention member.</p> |
