ABSTRACT:
The invention relates to a dual steering system for a tandem-type surface compacting machine equipped with two independent steering modes, for example, a machine equipped with both frame steering (3) and with individual steering (6) of one of the rollers (4a). The invention provides a control of both systems, one enabled by a steering-wheel activated steering valve (11) and the other enabled by a joystick-activated control valve ( 12). The control valve ( 12) is operatively connected to the switching valves (14a to 14d) which are activated with an electric switch in such a way that the machine operator can instantly select the steering mode whose activation with the steering wheel or joystick he deems most appropriate at any given time.
