Introduction
McCormick-Deering W-40 Standard-Tread Tractor
The McCormick-Deering W-40 is a standard-tread agricultural tractor manufactured by International Harvester in Milwaukee, Wisconsin, between 1935 and 1940. It was developed to serve as a high-capacity machine for heavy-duty farming operations during the pre-war era.
Engine and Performance
The W-40 is powered by an International Harvester 6-cylinder gasoline engine. Initial production models utilized a 242 cubic-inch (4.0 L) displacement, which was later increased to 298 cubic inches. The engine is liquid-cooled and features an oil bath air cleaner to maintain performance in dusty field conditions. It operates at a rated speed of 1750 RPM, delivering approximately 50 horsepower.
Transmission and Drivetrain
The tractor is equipped with an unsynchronized gear transmission, utilizing a dry disc clutch. Operators could choose between a 3-speed or 4-speed configuration, with one reverse gear available. The 4-speed variant included a high-speed fourth gear specifically intended for tractors equipped with rubber tires. Power is transferred to the rear wheels via a bull gear final drive system.
Dimensions and Mechanical Specifications
With a wheelbase of 85 inches and a total weight of 6100 lbs, the W-40 provides a stable platform for field work. The machine features manual steering and an open operator station. It was originally supplied with steel wheels, specifically 34x6 at the front and 50x12 at the rear. The rear tread width is set at 53 inches, while the front tread measures 52.25 inches.
Conclusion
The McCormick-Deering W-40 represents a significant period in American tractor manufacturing. Its robust design, characterized by a 6-cylinder engine and durable gear-driven transmission, made it a staple for large-scale agricultural tasks of the mid-1930s. A notable detail for collectors is the transition of the factory paint scheme from grey to red, which occurred on November 1, 1936.
