Abstract
A work vehicle includes left and right track assemblies, each track assembly including a main frame, a pivot member, a pivot shaft coupled to the pivot member, and an actuator coupled between the pivot shaft and the main frame. Each pivot member is mounted to a respective main frame to permit pivotal steering movement about a generally vertical steering axis for steering the track assemblies under the influence of the actuator. Additionally, each track assembly is pivotal about a generally horizontal pitch axis of the respective pivot shaft to permit pitch movement of the respective track assembly. Each track assembly is also pivotal about a generally horizontal camber axis through a portion of the respective pivot member to permit camber movement of the respective track assembly.
