Snowmobile Vehicle

• Individual snowmobiles
Numerous people had ideas for a smaller personal snowmobile. In 1914, O.M. Erickson and Art Olsen of the P.N. Bushnell company in Aberdeen, South Dakota built an open two-seater "motor-bob" out of an Indian motorcycle modified with a cowl-cover, side by side seating, and a set of sled-runners fore and aft. While it did not have the tracks of a true snowmobile, its appearance was otherwise similar to the modern version and is one of the earliest examples of a personal motorized snow-vehicle. Edgar and Allen Hetteen and David Johnson of Roseau, Minnesota were among the first to build a practical snowmobile in 1955–1956, but the early machines were heavy (1,000 lb/450 kg) and slow (20 mph/32 km/h). Their company, Hetteen Hoist & Derrick Co., became Polaris Industries, a small snowmobile manufacturer.
It was only in 1960, when engines became lighter and smaller than before, that Bombardier invented what we know as the modern snowmobile in its open-cockpit one- or two-person form, and started selling it as the "Ski-doo". Competitors sprang up and copied and improved his design. In the 1970s there were over a hundred snowmobile manufacturers. From 1970 to 1973 they sold close to two million machines, a sales summit never since equalled, with a peak of half a million in 1971. Many of the snowmobile companies were small outfits and the biggest manufacturers were often attempts by motorcycle makers and outboard motor makers to branch off in a new market.
Most of these companies went bankrupt during the gasoline crisis of 1973 and succeeding recessions, or were bought up by the larger ones. Sales rebounded to 260,000 in 1997 but went down gradually afterward, influenced by warmer winters and the use during all four seasons of small one- or two-person ATVs. The snowmobile market is now divided up between the four large North American makers (Bombardier Recreational Products (BRP), Arctic Cat, Yamaha, Ski-doo and Polaris) and some specialized makers like the Quebec-based AD Boivin (manufacturer of the Snow Hawk) and the European Alpina Snowmobiles.
