The Machines That Built American Farms
Before GPS guidance, climate-controlled cabs, and computerized controls, American farmers depended on tractors that were simple, rugged, and built to work. Some became so reliable that families kept them running for generations, repairing them instead of replacing them. From early Fordsons to powerful John Deeres, these 26 classic tractors helped transform American agriculture, and many are still working today.
Fordson Model F (1917)
Henry Ford's Fordson Model F helped bring affordable mechanization to American farms. Introduced in 1917, its compact design and relatively low price made it an attractive alternative to horses and expensive steam-powered equipment. The Fordson could plow, cultivate, and operate belt-driven machinery, reducing the labor required for everyday farm work. More than 700,000 were built worldwide, and surviving examples remain popular with collectors who appreciate their importance in agricultural history.
