A power machine (10) includes one or more steerable wheels (14). The wheels (14) are steerable using a hydraulic actuator (202, 204) to drive steering movement of the wheels (14). The power machine (10) also includes steering angle sensors (302, 304) which sense the steering angle and provide a signal indicative of the angle at which the wheels (14) are disposed relative to a longitudinal axis of the power machine (10). A hydraulic control system controls pressure of hydraulic fluid provided to the steering actuators (202, 204) based upon the steer angle position and desired change in position over time sensed by the steer angle sensors (302, 304).
