ABSTRACT:
A rider-controlled working machine having a four-wheel steering system including a steering link mechanism operatively interconnecting a steering wheel and front and rear wheels for steering the front and rear wheels simultaneously. The steering link mechanism includes a device for steering the rear wheels such that when the steering wheel is turned through a relatively large angle, the center of turning movement of the working machine is positioned between extensions of the axles of the front and rear wheels at the time the front and rear wheels are in a neutral steering position, and when the steering wheel is turned through a relatively small angle, the center of turning movement of the working machine is positioned between an extension of the transverse axis of an earth working unit coupled to the rear end of the working machine and the extensions of the axles of the rear wheels.
