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.

These Schebler carburetors lasted only through the prototype phases. Once the tractor went into production as the F-20, Gas Power Engineering began using 1.25-inch Zenith K5 models.
