A working machine has a ground engaging structure with front and rear pairs 22a, 22b of steerable wheels, a body 10 with a working arm 20, a front steering actuator for adjusting the steering angle of each of front wheel pair 22a to effect front wheel steering, a rear steering actuator for adjusting the steering angle of each of the rear wheel pair 22bs to effect rear wheel steering, an operator steering device for providing a steering demand, and an operator steering mode selector for selecting either a two wheel steer mode or a four wheel steer mode. The steering actuators are selectively operable in accordance with the steering demand and selected steer mode, and a steering ratio, namely the ratio of steering demand to turning angle of wheel pairs 22a, 22b, is different in the two wheel steer mode and four wheel steer mode. The steering ratio may depend on the travel speed of the machine.
