A snow blower is a mechanical device that collects snow and forcibly throws it away from a surface. Arthur Sicard invented it in Quebec in 1925. During the winter, these strong devices assist in keeping highways, sidewalks, and driveways clean.

They are used for transportation, recreation, hunting and trapping, especially in rural areas and the North. -
