A work vehicle includes left and right track assemblies, each track assembly having a main frame, a pivot member, a pivot shaft coupled to the pivot member, and an electrical actuator coupled between the pivot shaft and the main frame. The work vehicle also includes a control system having a controller communicatively coupled to each electrical actuator of the track assemblies. The controller includes processors that control the electrical actuator to steer the work vehicle about a generally vertical steering axis. Each pivot member is mounted to the main frame of the track assemblies. Each track assembly is pivotal about a generally horizontal pitch axis of the pivot shaft to permit pitch movement of the track assembly. Each track assembly is pivotal about a generally horizontal camber axis through a portion of the pivot member to permit camber movement of the track assembly.
