A working appliance controlled by a driver comprises a chassis 2, a plurality of wheels 501, 503 rotatably mounted on the said chassis, an engine 4 mounted on the said chassis in order to drive the said wheels, power transmission devices 6, 15 supported by the said chassis and functionally connected to the said engine, and power take-off shafts 36, 152 extending outside the said power transmission devices. The power take off shafts 36, 152 extend essentially horizontally in the transverse direction of the said chassis and coupling systems 111, 121 capable of moving at an angle about axes concentric with the said power take-off shafts are pivotally mounted on the chassis 2 for the coupling of working tools. Lifting devices 11, 12 driven hydraulically and mounted on the chassis 2 have oscillating arms 114, 124, the ends of which are connected to the said coupling systems, supporting them in such a way that they can move angularly. <IMAGE>
