John Deere was the trade name of snowmobiles designed and built by John Deere from 1972–1984. The initial design and testing phase came in 1970–1971, when engineers tested other popular snowmobiles, and found ways to improve them. The machines were produced by the John Deere Horicon Works of Horicon, Wisconsin along with lawn and garden products. Lawn and garden equipment is still manufactured there.
John Deere also had its own range of snowmobile suits.
The slogan "Nothing Runs Like a Deere", still used today by Deere & Co., started with the John Deere snowmobile line in 1972. From 1978 to 1980, JD used the slogan "Big John - Little John." In 1980, another new slogan was introduced: "Ride the new breed of Deere".
In 1980, John Deere was the official supplier of snowmobiles for the Winter Olympic Games in Lake Placid, New York.
In 1982–1984, the snowmobile market was in a downward slide, and the driving force behind the snowmobile program, executive vice president Robert Carlson, had left the company. This made ending the snowmobile program an easy decision for Deere. The parts supply and all snowmobile-related resources were sold to Polaris. There was an understanding that Polaris would continue where Deere left off, selling snowmobiles and parts to the Deere dealers that were interested. This never worked out. Recently a prototype Liquifire was uncovered in a Polaris warehouse which would have been one of the first snowmobiles to feature independent front suspension.
The Snowfire was the last production snowmobile on the market to have a free-air engine, and the last snowmobile in production for John Deere.
In 1974, a factory sponsored cross-country race team was assembled to go along with the introduction of the 295/S, Deere's first purpose-built snowmobile for cross-country racing. The team would eventually be known as "Enduro Team Deere". The team had many wins, the most notable being the 1976 Minneapolis - St. Paul International 500. Brian Nelson brought home the trophy on his Liquidator. His sled is currently on display at the Snowmobile Hall of Fame and Museum in St. Germain, Wisconsin. 1977 was the last year for the factory program. Instead, Deere offered support and incentives for independent racers.
