STEERING A DIFFERENTIAL STEERING MACHINE WHILE COMMANDED TO BE IN NEUTRAL

Abstract:

A method for steering a machine while commanded to be in neutral, including: sensing that a transmission is in a neutral setting; applying one or more service brakes into a braking mode; ramping off a steering pump on a hydraulic steering system; sensing a steering command; releasing the one or more service brakes from the braking mode in response to sensing the steering command; and ramping on the steering pump on the hydraulic steering system.
