  1. THE LESCHASIN MOTOR TOBOGGAN           ........ Peter Leschasin produced a number of interesting and unique machines in Rossburn, Manitoba. The Leschasin Motor Toboggan was available with a complete cab and was produced in one and two passenger models from 1958 to 1966.
  2. TRAIL-A-SLED, SCORPION            ................... Dick Harrison, Glen Gutsman, and Eugene F. Harrison began development of snowplanes in 1959. These machines were produced until 1961 when a change to single tracked snowmobiles was made. The company's name was changed to Scorpion in 1969 and the new company was sold to Arctic Enterprises in 1979.
  3. CHARLIE WINSLOW  ......................... Winslow's air sleds, produced in the late 50's, were of the three ski design, with a very wide rear ski tread. They were ideal for hunting and even featured sliding canopies which could be opened for 'shooting on the go.'
  4. ARCTIC CAT       ................................. Arctic Enterprises was started by Edgar Heteen in 1961 and became the largest producer of single tracked snowmobiles in the United States. In peak years they manufactured over 100,000 machines per year and were assembling 1000 machines per day. 
  5. THE WIESE SNO-PLANE              ...................... In 1961 Helmet L. Wiese of Swan Valley, Idaho began production of what were probably the fastest air sleds in existence.  The wide stance three ski machine, powered by an aircraft engine, provided many wins at the snowplane races.

Engineering Analysis ..............
The unique requirements of over snow travel are investigated. All sizes and types of snowmobiles and snowplanes are considered and such items as traction, steering, maneuverability, and stability are discussed.
