Abstract: A steering control system is for use on a vehicle having an operator station including a steering wheel that is turned by an operator of the vehicle to cause a steered wheel of the vehicle to pivot relative to a main body. The steering control system includes a hydraulic cylinder for changing a steered position of the steered wheel in response to movement of the steering wheel. The steering control system also includes a hydraulic circuit arrangement that varies a volume of hydraulic fluid flow provided to the hydraulic cylinder per degree of rotation of the steering wheel based on a rotational speed of the steering wheel.
