Abstract: A method and system releases a spring parking brake of an anchored machine. A hydraulic fluid source is provided. A towing force is applied to the anchored machine, and the applied towing force is sensed by a sensor. The sensor sends a signal to a hydraulic fluid source control device. The hydraulic fluid source control device causes hydraulic fluid from the hydraulic fluid source to be supplied to the spring parking brake to release the spring parking brake.
