Abstract
A work machine includes a frame, at least one drive wheel carried by the frame, at least one caster wheel assembly carried by the frame, and at least one turn assist arrangement. Each turn assist arrangement is coupled between the frame and a corresponding caster wheel assembly. Each turn assist arrangement is configured to bias the corresponding caster wheel assembly during an operator commanded turn, and to be overridden by forces applied by the ground to the caster wheel assembly.
