ABSTRACT:
A rotary snow plough vehicle having an auxiliary auger pivotable along a vertical plane perpendicular to the advancing direction of the vehicle. The auxiliary auger is rotatably secured about its axis by a supporting arm through bearings. Said supporting arm is positioned above a main auger and is swingable about a central shaft extending in parallel with the advancing direction of the vehicle. A tiltable cylinder is pivotably disposed between a frame and the supporting arm. By the extension and retraction of a piston rod of the cylinder, the supporting arm together with the auxiliary auger are swingably movable about the central shaft. The central shaft is extended from a deceleration means adapted to transmit the rotation of the main auger to the auxiliary auger. The auxiliary auger can be further provided with an extension auger in alignment therewith.
