ABSTRACT:
An automatic leveling vehicle comprising a front frame section and a rear frame section interconnected by a swivel joint which permits pivotable movement of the front frame section relative to the rear frame section about a generally horizontal axis extending longitudinally of the vehicle, a gear train attached to the rear frame section, right and left rear wheel assemblies, right and left rear axle assemblies operatively interconnecting the gear train, a lever arm connected to the gear train for controlling the position of the rear axle assemblies, selective movement of the lever arm causing the right and left rear axle assemblies to move their associated wheel assemblies up or down in opposite directions, a level detector for producing and applying leveling signals for positioning a lever arm control such that the rear frame section is maintained in a relatively level orientation when the rear wheel assemblies encounter an uneven terrain.
