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. The hydraulic circuit arrangement directs a first volume of hydraulic fluid to the hydraulic cylinder per degree of rotational movement of the steering wheel when the steering wheel is rotated at a first rotational speed, and directs a second volume of hydraulic fluid to the hydraulic cylinder per degree of rotational movement of the steering wheel when the steering wheel is rotated at a second rotational speed. The second rotational speed is larger than the first rotational speed and the second volume of hydraulic fluid being larger than the first volume of hydraulic fluid, wherein the steering control system is more sensitive when the steering wheel is rotated at the second rotational speed than the first rotational speed. The system also includes a sensor for sensing the steered position of the steered wheel, a display positioned at the operator station, the display providing an indication of the steered position of the steered wheel, and a controller that interfaces with the hydraulic circuit arrangement, the sensor and the display.
