The History of Farmall Tractors: 1930-1935

In order to keep up with the progress of competition, Ed Johnston proposed improvements to make the Farmall a better tractor. Discover the changes that occurred to create more modern, small-scale F-20s, F-30s and F-40s.

Tested at the University of Nebraska in May 1933, the F-12 developed 10.1 horsepower at the drawbar and 14.6 off the pulley or PTO. It weighed 2,700 pounds, compared with 3,950 pounds for the F-20 and 5,300 pounds for the F-30.
