Farmall A

Last Updated: September 2024

Overview

The Farmall A is a compact row crop tractor that was made from 1939 to 1947. It's a 2-wheel drive tractor with a manual steering system and a simple sliding gear transmission. This tractor has 4 forward gears and 1 reverse gear, making it easy to use in different field conditions.

Under the hood, the Farmall A has a small 4-cylinder engine made by International Harvester. The engine can run on gasoline or kerosene and is air-cooled, which means it doesn't need a radiator. It has a very low engine displacement compared to other tractors, but its rated RPM is also quite low. The tractor is lightweight, weighing only 2,400 pounds, which is much less than most tractors. It has a 540 RPM power take-off (PTO) that connects to the transmission, allowing it to run various farm tools. The Farmall A has an open operator station and can be started with an electric starter or by hand. Its small size, measuring about 106 inches long and 77 inches wide, makes it great for working in tight spaces between crop rows.
