ABSTRACT:
A steering control apparatus is disclosed for a first and second pair of wheel assemblies that are mounted for rotation with respect to a first and second axle. Selective rotation of the respective wheel assemblies is controlled by a plurality of actuators defined by a control module. The actuators are engaged by a control lever that is mounted for movement with respect to the control module in a preselected plane. The control module is rotatable with respect to the preselected plane to allow selective contact between the actuators and the control lever to control the rotation of the wheel assemblies with respect to the axles in one of a plurality of steering modes.
