i-20-233B6M/KK/80 ABSTRACT OF THE DISCLOSURE A snow plough vehicle including a novel snow chute apparatus, a power transmission system, a main auger and 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 singably 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 there- with. Said chute apparatus includes arcuate stationary duct and at least one arcuate movable duct, These ducts have axial cur- vatures equal with each other. The movable duct is vertically movable to extend from said stationary duct in operative state and to superimpose therewith during non-operative state in response to the operation of a means for moving said movable duct. Said power transmission system is provided with a variable clutch means between a vehicle running mechanism and a distribution means connected to an engine. The distribution means is adapted to transmit engine output to either or both the snow plough mechanism and the vehicle running mechanism.
