Introduction
International Harvester Farmall Super A
The Farmall Super A is a utility tractor produced by International Harvester between 1947 and 1954. Serving as an evolution of the original Farmall A series, it was designed to provide increased operational versatility through the introduction of the Touch-Control hydraulic system.
Engine and Performance
The tractor is powered by a 1.9-liter (113.1 cubic inch), 4-cylinder, liquid-cooled engine. It operates at a rated speed of 1400 RPM and is designed to run on kerosene. The engine delivers approximately 17 horsepower, providing sufficient output for standard agricultural tasks of the era.
Transmission and Drivetrain
The powertrain features a sliding gear transmission with four forward gears and one reverse gear. Power is transferred to the wheels via a 9-inch dry disc clutch. The tractor is configured as a two-wheel-drive unit, utilizing differential mechanical contracting band brakes for stopping control.
Hydraulics and Hitch
A defining feature of the Super A is the IH Touch-Control hydraulic system. This system, which replaced the earlier 'Lift-All' design, provides a capacity of 2.1 gallons (7.9 liters) and includes a single valve. It is integrated with a mid-mount Touch Control rockshaft hitch to facilitate implement management.
Dimensions and Handling
The tractor has a wheelbase of 71.1 inches (180 cm) and a base operating weight of 2,400 lbs (1088 kg), which can be increased through ballasting. The adjustable rear tread width, ranging from 40 to 68 inches, allows for adaptation to various row-crop configurations. It is equipped with 5.00-15 front tires and 9-24 rear tires.
Conclusion
With 107,636 units produced, the Farmall Super A remains a significant model in tractor history, recognized for its transition to modern hydraulic implement control. It is well-suited for small to mid-sized field operations and is a common subject for restoration among vintage tractor enthusiasts.
