Last Updated: June 2024

Overview

The Farmall F20 tractor was a game-changer in the agricultural industry when it was introduced. Farmall, a part of International Harvester, manufactured these tractors with practicality in mind from 1932 to 1939 in Rock Island, Illinois, USA. The F20 model featured a 220.9 cubic-inch, four-cylinder International Harvester engine with liquid cooling, and a 4-speed transmission with a 279.4mm mechanical dry disc clutch. Rated at 26.7 horsepower and 1200 rpm, this tractor was built to deliver robust performance for its time. It was a 2WD tractor with a 4x2 chassis and manual steering, making it suitable for the row-crop duties it was designed for. The straightforward open operator station was a standard of the era, focusing on function over comfort. At an operating weight of 4400 lbs, it was not a light machine, emphasizing its build quality and durability.
