Ski Whiz was the snowmobile brand of Massey-Ferguson, the farm machinery company created in 1953 from the merger of Massey-Harris of Canada and Harry Ferguson Limited of the United Kingdom. In 1969, as snowmobiling boomed across North America, Massey-Ferguson began producing a line of snowmobiles under the Ski Whiz name. The Ski Whiz line was part of a wave of snowmobile programs launched by established manufacturers during the late-1960s boom.

Massey-Ferguson brought a farm-equipment approach to the snowmobile business, and Ski Whiz sleds were sold and serviced through the company's established dealer network. The machines spanned the practical and the sporty ends of the 1970s market. Ski Whiz production ended in 1977 when declining snowmobile sales led the company to close the line, and the brand has been defunct since; surviving examples are now collector machines prized by vintage snowmobile enthusiasts. The lineup was updated through the early 1970s as styling, suspension, and engine technology advanced quickly across the industry.

Ski Whiz workshop manuals cover the two-stroke engines, drive clutches and chaincases, suspensions, steering, skis, and electrical systems used across the model range. Manuals provide step-by-step repair procedures, torque specifications, wiring diagrams, and troubleshooting guidance.

Restorers and do-it-yourself owners of these vintage sleds will find the documentation valuable, and independent shops that work on classic snowmobiles can also rely on it. Since production ended decades ago, surviving examples are uncommon and correct documentation is essential for faithful restoration.
