Abstract: A device allowing positioning of wheels of a snowmobile when skis leave a snowy path to continue on a road. The device comprises at least two parallel wheels positioned near each ski, a pair of cylinders placed in connection with each wheel, and controlled by a control box by a driver activating pistons to move the wheels from an upward position to a downward ground position. The upward position corresponds to wheels elevated over the ski when the piston is contracted; and the downward position corresponds to wheels in touch with the ground when the piston is extended. Means of clutch move horizontally the wheels to an external position. A spike located on an arm which supports a wheel is positioned to scratch ground ice for creating a mist when a wheel is in a scratching position.

Abstract: The present invention relates to a prior application U.S. Ser. No. 11/705,116 <<ANTI-ZIGZAG GUIDE RAIL FOR SNOWMOBILE SKI>> wherein a flat rectangular extension (122) is added to protect from wear the skittle of a snowmobile ski when crossing rocky paths. The flat extension is used as floating link between the guide and the tail (131) of a wear runner laid out longitudinally of the ski. The guide (120) located at the front of the ski is always engaged, along with the self-sharpening runner, in ice, while the extension (122) keeps the back of the ski flat. The extension may be of a reversed U-shape comprising an extra web (135) and two extra cutting wings (136) protruding from the web (135) to a certain depth in direction of the ground and longitudinally of the extension, thus defining five cutting trails.

Abstract: The present invention relates to snowplow (200) systems provided with a shovel (105) utilized generally for scraping snow (106). Articulated blades (20), resembling a hand (21) having a Y or a H shape, wherein wear knives (22) are inserted and locked in place between twin blades (23), by particular means of retention, permitting to increase the longevity of the blades during frequent passages over altered roads. The blades are provided also with a skate (129) system at an attack corner (139) preventing the breaking of the blade and allowing the blade to follow the irregularities of the road. The blades are installed lengthwise along the snowplow.

Abstract: A guide fixed at the front of a ski of a snow vehicle (22) and including two wings (40) of reversed U-Shape, whose web (60) is linked to the lower face of the ski, the guide including means of initialization (64) of a rectangular runner (48) which is laid out sideways, in continuation and in line with the guide. A ski of a snow vehicle used in combination with a wear runner which is laid out longitudinally of the ski, the bottom face of the ski having in its fore end a pair of downward wings (40) acting as knives and spaced to guide the snow on the two sides of the wear runner. The existing methods of stabilization of snow vehicle implying a sole carbide runner are improved by the presence of the guide, which guides the runner through the trails left by the passage of skis of other snow vehicles. The runner is further improved by a rectangular section thereof, which is laid out sideways and longitudinally of the ski and by its being self sharpening.

Abstract: A stabilizer comprising three parallel wear blades each of which is made to remain sharpened over a long period of time. The side blades may contain holes to divert the snow and to add roughness when engaging into a ski path, while a rectangular central part runner provides a blade support of a given hardness and holding a central carbide blade of a much higher hardness, thereby permitting passage over rugged hard terrain without wearing the blade support. In soft abrasive gravel, the blade support wears partially thereby leaving a protruding central part, the protruding difference being self adjusting. In the case of the concave ski each side comprises a rectangular edge wear part coupled with a side blade for a total of four wear blades. The rectangular central part may be used alone, along with its central carbide blade within it.

Abstract: Improvements in snowmobile stabilizers are now available. The stabilizer comprises three parallel wear blades each of which is made to remain sharpened over a long period of time. The side blades may contain holes to divert the snow and to add roughness when engaging into a ski path, while a rectangular central part provides a blade support of a given hardness and holding a central blade of a much higher hardness, thereby permitting passage over rugged hard terrain while protecting the blade support against rapid wear. In soft abrasive gravel, the blade support wears partially thereby leaving a protruding central part, the protruding difference being self adjusting. In the case of the concave ski each side comprises a rectangular edge wear part coupled with a side blade for a total of four wear blades.

Abstract: A stabilizer made of metal or plastic, fit on snow vehicle ski. It comprises a vertical fin forming a wing of a U-shaped section of a length sufficient to cover the bearing surface of the ski. A central channel is placed longitudinally in the centre of the U-shaped section to form with the wings a series of three parallel guides, digging a track on a surface to stabilize the direction of the ski in motion. When applied to a snowmobile ski the central channel is a bar such as used currently to protect the ski in asphalt crossings. Its wings are of steel and have a wall 19 mm high and 2 to 3 mm thick. The web is 56 to 58 mm wide and supports a corrector 6 mm thick and 56 mm wide and stretches on all the ski length. The bar is 6 mm higher than the wings.
