Abstract: A snowmobile warning and control method for a snowmobile having an engine and a brake system, including: sensing a temperature of the brake system of the vehicle; determining that the temperature of the brake system is above a first predetermined temperature threshold; issuing a first brake-system temperature warning in response to the temperature of the brake system exceeding the first predetermined temperature threshold; determining that the temperature of the brake system is above a second predetermined temperature, the second predetermined temperature being greater than the first predetermined temperature; issuing a second brake-system temperature warning in response to the temperature of the brake system exceeding the second predetermined temperature threshold; and modifying an operation of the engine in response to the temperature of the brake system exceeding the second predetermined temperature threshold.

Abstract: A snowmobile ice scratcher has a wire form in the shape of a hook secured to a track frame of the snowmobile. The wire form has a coil portion at the track frame and a downwardly extending leg portion that in an undeflected position has an elongate snow/ice spray generating portion configured as a flattened wire segment portion oriented downwardly, forwardly, and inwardly for generating snow/ice spray on hard packed snow and/or ice surfaces. An upwardly facing flat surface of the elongate snow/ice spray generating portion faces upwardly, inwardly, and forwardly and creates an ice/snow spray as the snowmobile is moving forward that is primarily directed inwardly to provide improved lubrication of the track assembly and improved deposition of ice/snow spray under the tunnel on a heat exchanger, thereby providing improved cooling of the snowmobile engine. The hook shape of the leg portion allows rearward operation of the snowmobile without damage to the ice scratcher.
