In one embodiment, a steering system for an agricultural implement system includes a first actuating cylinder configured to rotate a first track relative to an implement frame where the first actuating cylinder is connected to a first frame of the first track, and a second actuating cylinder configured to rotate a second track relative to the implement frame where the second actuating cylinder is connected to a second frame of the second track. The steering system also includes a first fluid control conduit extending to a cap end of the first actuating cylinder, a second fluid control conduit extending between a rod end of the first actuating cylinder and a rod end of the second actuating cylinder, a third fluid control conduit extending to a cap end of the second actuating cylinder, and a steering control valve in fluid communication with the first and third fluid control conduits.

Implement steering system

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.

Implement control system for electrical actuator of steerable track assembly pivotable about three axes

An actuator assembly for an implement includes a pivot shaft configured to be received in a tubular member rigidly coupled to an implement frame, configured to pivot relative to the tubular member about a generally horizontal pitch axis, and configured to support a track assembly of the implement and to enable the track assembly to pivot about the generally horizontal pitch axis. The actuator assembly also includes an actuator anchor disposed on the pivot shaft. Further, the actuator assembly includes an actuator having a first longitudinal end and a second longitudinal end. The actuator is coupled to the actuator anchor at the first longitudinal end, and the actuator is configured to be coupled to a track assembly frame of the track assembly at the second longitudinal end. Moreover, the actuator is configured to extend and retract to pivotally steer the track assembly about a generally vertical steering axis.

Implement steerable track assembly with pivoting steering actuator

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 track assembly is configured to permit pivotal steering movement, pivotal pitch movement, and pivotal camber movement. The actuator of each track assembly is coupled to the respective main frame at one end of the actuator, and at an opposite end of the actuator to an actuator anchor via a self-aligning bearing arrangement to permit transmission of steering forces while enabling pivotal movement of the respective track assembly.
