摘要:
An agricultural implement system is provided that includes a valve in fluid communication with first and second actuating cylinders and with first and second fluid conduits. The valve is configured to control fluid flow from the first and second fluid conduits to the first and second actuating cylinders. Furthermore, a controller is communicatively coupled to first and second pressure sensors and to the valve. The first pressure sensor is coupled to the first fluid conduit, and the second pressure sensor is coupled to the second fluid conduit. The controller is configured to determine whether the first fluid conduit or the second fluid conduit is supplying fluid to the valve based on signals from the first and second pressure sensors, and to automatically control fluid flow to the first and second actuating cylinders such that wheel assemblies are rotated to a desired angle relative to an implement frame.
