Electronically controlled hydraulic valves can be directly mounted to rear steering cylinders of a four wheel steering machine to improve steering, reduce space consumption, reduce leak points and allow ease of routing. The valves can receive hydraulic fluid from a pump and release hydraulic fluid to tank, while controlling an amount of hydraulic fluid to the steering cylinder via inlets and outlets in direct contact. The valves can be controlled by a controller that is also in communication with position sensors configured to sense positions of the front and rear steering cylinders, so that the directly mounted valves in the rear can be correspondingly controlled to follow steering in the front.
