Abstract: An ice scratcher for attachment to a snowmobile has a first ice scratcher end, a second ice scratcher end opposite the first ice scratcher end, a first coil spring having a first spring axis disposed at or near the first ice scratcher end, a first elongated member having a first end connected to the first coil spring, a second coil spring connected to a second end of the first elongated member, the second coil spring having a second spring axis, and a second elongated member having a first end connected to the second coil spring and a second end at or near the second ice scratcher end. Alternative embodiments of the ice scratcher are disclosed. A snowmobile having the ice scratcher is also disclosed.

Abstract: An ice-particle spray generating device for use on snow vehicles is disclosed. The present invention provides an adapter having a locking device to prevent the connecting means of the ice-particle spray generating device to loosen when the snow vehicle is travelling.

Abstract: A snowmobile includes a frame having a steering hoop structure and a tunnel. The steering hoop structure is coupled to first and second side panels of the tunnel and extends above the tunnel. The first and second side panels of the tunnel each include a running board supported by the steering hoop structure. The steering hoop structure includes a toe clip positioned adjacent to each of the running boards.

Abstract: A bi-directional ice-particle spray generating device for use on snow vehicles is disclosed which is primarily constructed of multi-strand wire rope. The use of wire rope as a spring member allows for 360 degree flexibility to enable the design to be compatible with reverse-gear-equipped snow vehicles. A replaceable wear point or points is integral in the design for added durability.

Abstract: A snow lubrication device attaches to a vehicle body of a snowmobile and includes a pair of snow rake rods extending from the vehicle body to contact a snow surface. A snow rake member located at the end of the snow rake rod scatters snow. The scattered snow lubricates gaps between a track belt and the slide rail and/or between the track belt and the drive wheel. The lubrication of the track belt improves operation of the snowmobile if the lower part of the snow rake rod strikes a stone or the like, the snow rake rod temporarily deflects further rearward. The snow lubrication device has relatively few components, is low in cost, and is hard to dislodge from a snowmobile.

Abstract: A snowmobile includes a chassis having a generally reduced length and a snow flap pivotally attached to the rear portion of the chassis, above the track system. The track system extends rearwardly beyond the chassis, and the snow flap shields the track system above and behind from spraying snow. The snow flap is linked to the track system so that as the track system moves through a range of travel relative to the chassis, the snow flap pivots relative to the chassis with the track system. This configuration prevents damaging contact between the tread and the undersurface of the snow flap and/or the chassis. The reduced length of the chassis decreases the weight of the snowmobile and the polar moment of inertia, thereby improving turning performance. A bumper extends from the snow flap and can be used to lift the rear of the snowmobile more easily.

Abstract: A traction enhancement system (10) for a snowmobile (12) that includes a front plate member (14) and deflection plates (16) mounted ahead of the snowmobile body (18) for deflecting and compressing fresh, ungroomed snow to enhance traction, startability, and stability of the snowmobile in heavy and rough snow conditions. The front plate member (14) comprises an upper screen (40) offset ahead of a lower screen (42), with both screens being attached to the bumper (36) to angle downward toward the tail section (28) of the snowmobile (12). Each deflection plate (16) is bent along a longitudinal axis and mounted to the tip (32) of the skies (30) to deflect snow to either side of the skies (30). The front plate member (14) and the deflection plates (16) are slidably engaged within their respective receiving tubes (61) and (98), which are attached to the snowmobile (12) to facilitate quick and easy attachment and detachment.
