Introduction
International Harvester 10-20 Tractor
The International Harvester 10-20 is a standard-tread tractor produced between 1915 and 1920 in Milwaukee, Wisconsin, USA. It represents a significant era in early 20th-century agricultural mechanization, designed to provide reliable mechanical power for field operations.
Engine and Performance
The tractor is powered by an International Harvester two-cylinder, liquid-cooled engine with a displacement of 8.7 liters (530.9 ci). It utilizes a horizontal valve-in-head configuration and operates on kerosene fuel. The engine is rated at 575 RPM and is started manually via a hand-crank mechanism. The cooling system has a substantial capacity of 151.4 liters to maintain operating temperatures during heavy use.
Transmission and Drivetrain
The 10-20 features a manual gear-type transmission providing two forward gears and one reverse gear. This transmission requires 11.4 liters of oil for lubrication. The machine is configured as a two-wheel-drive unit, relying on manual steering systems, which was standard practice for tractors of this period.
Dimensions and Build
This tractor has a total weight of 2,506 kg (5,525 lbs) and a wheelbase of 231 cm (91 inches). Its total length is 373 cm (147 inches) with a width of 152 cm (60 inches). It is equipped with steel agricultural wheels, featuring 36x6 dimensions for the front and 54x10 for the rear, providing the necessary traction for its era.
Conclusion
With a drawbar power of 7.5 kW (10 hp) and a belt power of 14.9 kW (20 hp), the International Harvester 10-20 was designed for light to moderate agricultural traction and stationary belt-driven tasks. Its robust, simple construction remains a point of interest for collectors and historians of agricultural machinery.
