Introduction
International Harvester Type A 12HP Standard-tread Tractor
The International Harvester Type A 12HP is a historical standard-tread tractor produced between 1908 and 1911 in Upper Sandusky, Ohio, USA. Representing an early stage of agricultural mechanization, this machine was designed as a reliable power source for field operations during the early 20th century.
Engine and Performance
The tractor is powered by a 1-cylinder, liquid-cooled gasoline engine with a displacement of 530 cubic inches (8.7 liters). It operates at a rated speed of 300 to 350 RPM. Due to the era of its design, the engine is started via a manual hand-crank. The cooling system is notably large, with a capacity of 232 quarts (219.6 liters). The machine provides 12 belt horsepower (8.9 kW) and is rated for pulling two plows.
Transmission and Mechanical Specifications
The drivetrain consists of a gear-based transmission offering one forward gear and one reverse gear. It is a two-wheel-drive machine featuring manual steering. The tractor is equipped with steel rear wheels measuring 56x16 inches, which were standard for the period. The total weight of the tractor is 9,000 lbs (4,082 kg), contributing to its traction capabilities.
Operator Environment
The operator station is an open design, typical of early industrial-era tractors. To provide basic protection from the elements, the station is equipped with a steel canopy. The total width of the machine is 88 inches (223 cm).
Conclusion
The International Harvester Type A 12HP is a significant example of early agricultural engineering. With its substantial weight and specific design for primary tillage, it served as a robust, albeit simple, solution for farmers of the early 1900s, and it remains a notable subject for vintage tractor collectors.
