Fordson Engine Conversions

Converting Ford Tractors to V-8 Power Didn't Start with the 8N that Honor Falls to the Pioneering Fordson

| April/May 2003

Converting Ford 8Ns or 9Ns to Ford six-cylinder or V-8 engines was almost commonplace at one time, but those conversions didn't come along until after the introduction of the Ford-Ferguson tractor of 1939.

What many people don't realize, however, is that as early as the 1920s and 1930s backyard mechanics were busy fitting different engines into Fordson tractors. The most popular conversion involved shoehorning a flathead Ford V-8 in place of the Fordson's Hercules-designed four-cylinder engine, which originally come out in 1917-1918. But Fordson engine conversions were hardly confined to Ford V-8 engines and ran the gamut, including a diesel engine in a 1920 Fordson tractor and, later, a factory-quality Lister diesel conversion.

John Swanson, an enterprising gentleman from Almena, Wis., and founder of the Swanson Machine Co., built what he called the 'Linkon' tractor, so named when he 'linked on' a Buick or GMC truck engine to a Fordson chassis. This resulted in a stretched-out, more powerful Fordson giving low-cost belt power for threshing, filling silos and other farm chores. Seeing that Swanson was also the local Case tractor dealer you might wonder why he didn't convert a Case tractor instead of a Fordson, but perhaps it was because the low initial price of a Fordson meant he could sell his Linkon for only $495. Swanson was not the only one using GM engines, as other handy farmers installed Chevrolet six-cylinder engines in their Fordsons.

Different Engines, Different Fuels

Meanwhile, after the English Fordson 'IS' went in full production in 1932, the British Fordson Tractor Co. experimented with retrofitting the Fordson N with a Perkins diesel engine. This proved so successful they eventually bought the Perkins Company for future, factory-installed diesel engines, which became the standard of the industry in the Fordson Major of 1952-1953. Experiments with these 1932 diesel-powered Fordsons convinced British and

Fordson engine conversions went well beyond simply dropping in a Ford flathead V-8.

Enterprising owners experimented with a variety of power plants for the venerable Fordson, including diesel engines and six-cylinder engines.
