Introduction
Farmall Super A-1 Row-Crop Tractor
The Farmall Super A-1 is a row-crop tractor produced in 1954 by International Harvester. As a refined iteration of the Super A series, the Super A-1 is distinguished by its integration of the C123 engine, providing increased displacement while maintaining the tractor's characteristic utility in row-crop operations. A total of 1,672 units were manufactured.
Engine and Performance
The tractor is powered by a 123 cubic inch (2.0 L) 4-cylinder liquid-cooled engine. It operates with a 6:1 compression ratio at a rated engine speed of 1450 RPM. The engine cooling system has a capacity of 15 quarts (14.2 L), while the oil system requires 5 quarts (4.7 L).
Transmission and Drivetrain
Power is transferred to the two-wheel drive system through a gear-type transmission featuring 4 forward gears and 1 reverse gear. The drivetrain utilizes a 228.6mm dry disc clutch. The tractor is equipped with a standard 540 RPM rear power take-off (PTO) to operate various agricultural implements.
Chassis and Dimensions
The Super A-1 features an open operator station with manual steering and mechanical band brakes. Its dimensions include a wheelbase of 71.1 inches (180 cm) and an overall length of 106.9 inches (271 cm). The tractor provides a front axle clearance of 22.25 inches (56 cm) and a rear axle clearance of 21.6 inches (54 cm). The front tread is adjustable from 44 to 64 inches, and the rear tread is adjustable from 40 to 68 inches to suit specific row-crop spacing requirements.
Electrical System
The electrical system is based on a 6-volt battery architecture. Charging is managed by an engine-driven generator, and the system utilizes a positive ground configuration.
Conclusion
The Farmall Super A-1 represents a classic example of mid-1950s row-crop engineering. Its combination of a 2.0 L engine, adjustable tread widths, and 540 RPM PTO makes it a specialized tool for light-to-medium field tasks. With only 1,672 units produced, it remains a notable machine for collectors and enthusiasts of International Harvester equipment.
