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.

By 1935, all F-30s used 1.25-inch Zenith K5 carburetors. The engines developed 20.3 horsepower on the drawbar and 30.3 off the pulley or PTO.
