A control system for a working machine includes a device for changing direction of the working machine, an operator controlled lever, and an electronic control unit adapted to receive an input signal indicative of desired direction from the position of the operator controlled element and to generate an output signal for producing a change of direction of the working machine, corresponding to the position of the operator controlled element, via said device. The control system includes an electronic safety device adapted to be controlled by the position of the operator controlled element and adapted to allow control of the device via the output signal and to block control of the device via the output signal, respectively, depending on the position of the operator controlled element.
