What the A is used for
The Farmall A excels at light tillage, cultivation, mowing, and general work on small acreages. Its offset engine and wide front end were central to the Cultivision design, giving the operator a clear view of rows.
It is not a modern loader or high-horsepower implement tractor. Use implements sized for its one-bottom, roughly 17 drawbar-hp capability and recognize that the transmission-driven PTO stops when the clutch stops the transmission.
Why the Farmall A stands out
The defining feature is Cultivision: the offset engine, steering, and seat arrangement improves visibility for row-crop cultivation. The simple 4-speed drivetrain, compact 2,400 lb size, and large production total also make it a popular restoration and parade tractor.
Buying a used Farmall A
Check that the engine serial and chassis identify an A rather than a visually similar B, and inspect the offset platform and steering components for repairs or damage. Test the Lift-All system, brakes, cooling system, and transmission in every gear; verify whether the tractor is gasoline or kerosene because fuel-system details differ.
