ABSTRACT:
A vehicle has a frame (2), wheel assemblies (3) connected to the frame, and a lateral support assembly (4) connected between each of the front wheel assemblies and the rear wheel assemblies. Each wheel assembly is pivotally connected by an upper pivot member (92) to an upright post (24). A collar (85) is slidable up and down on each post. Bracing hydraulic cylinders (115) connect between the support assembly and the wheel assemblies. A control circuit for the cylinders (115) with a control valve (177) maintains the wheel assemblies upright. Elevator hydraulic cylinders (127) transmit the weight of the frame to the wheels. A control circuit with position control valves (153) automatically adjusts the elevator hydraulic cylinders (127) to hold the frame at a preset elevation and a control circuit with position control valves (171) automatically adjusts the wheel spacing hydraulic cylinders (166) to hold the wheels at a preset spacing. A control circuit regulates the speed and direction of hydrostatic motors (182) on the wheels and the turning of the wheels.
