Working Machine

A method of operating a working machine which includes a body and an axle which is mounted so as to be moveable relative to the body, the axle carrying at or towards each end, a ground engaging wheel by means of which the machine is moveable on the ground, the machine including a speed sensor sensitive to the machine ground speed, and there being a hydraulic control system including at least one control actuator connected between the body and the axle for controlling movement of the axle relative to the body, and the hydraulic system further including at least one control valve which is operable to restrict fluid flow occurring as a result of the control actuator extending or retracting in response to axle movements relative to the body, the method including restricting fluid flow proportionally depending upon a signal provided by the speed sensor.

A method of operating a working machine which includes a body and an axle which is mounted so as to be moveable relative to the body, the axle carrying at or towards each end, a ground engaging wheel by means of which the machine is moveable on the ground, and there being a hydraulic fluid control system including at least one control actuator connected between the body and the axle for controlling movement of the axle relative to the body, and at least one control valve which is operable to at least restrict hydraulic fluid flow in the system occurring as a result of the control actuator extending or retracting in response to axle movements relative to the body, and a controller which provides command signals to the control valve to vary the restriction to fluid flow, depending on a control regime, and the working machine including an auxiliary hydraulically operated service, and when the auxiliary hydraulically operated service is operated, the restriction to hydraulic fluid otherwise provided by the control valve in accordance with the control regime is at least partially relieved.
