Abstract
A method of operating a working machine which includes a main structure and a working arm pivotally mounted at one end on the main structure. The working arm is raisable and lowerable relative to the main structure by a first actuator device, and is extendible relative to the main structure by a second actuator device. In use, the arm carries at another end a working implement which can carry a load. The machine further including a ground engaging drive structure by which the machine is drivable on the ground. The machine has a longitudinal load moment control system which automatically disables operation of the first and/or second actuator devices from increasing longitudinal instability in the event that a predetermined instability is sensed. When the machine senses a ground travelling speed above a threshold speed, the longitudinal load moment control system is disabled.
