These devices, typically mounted beneath a snowmobile’s rails, make contact with the icy surface and shave off ice particles. This shaved ice is then thrown up into the track and tunnel area. A common design incorporates spring-loaded, carbide-tipped claws.
Cooling a snowmobile’s engine and other components is crucial for optimal performance and longevity. When operating on icy surfaces, the track’s friction against packed snow the primary cooling mechanism is significantly reduced. Employing such devices allows for sufficient cooling by providing a steady supply of ice chips, preventing overheating, potential damage, and diminished performance. This practice has become particularly important with the development of higher-performance engines and the increasing prevalence of groomed trails.
