Introduction
McCormick-Deering W-9
The McCormick-Deering W-9 is a standard-tread agricultural tractor produced by International Harvester between 1940 and 1953. As part of the 9-series, this machine was engineered for heavy-duty field operations and was manufactured at facilities in Melrose Park, Illinois, and Milwaukee, Wisconsin.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled engine with a displacement of 334.5 cubic inches (5.5 L). It features a bore and stroke of 4.40x5.50 inches and operates at a rated speed of 1500 RPM. Originally designed as an all-fuel engine capable of running on distillate and low-octane gasoline, it served as the standard power unit until 1947, after which a dedicated gasoline engine became the standard configuration.
Transmission and Drivetrain
The W-9 utilizes a sliding gear transmission providing 5 forward speeds and 1 reverse gear. For units equipped with steel wheels, the fifth gear was factory-locked to limit operational speed. The tractor is configured with a two-wheel drive system, providing direct power to the rear wheels.
Mechanical Systems
Steering is managed via a manual worm-type gear system, which was standard for the period. Braking functionality is handled by differential external contracting band brakes, allowing for independent control of the rear wheels to assist in maneuvering during field work. The operator station is of an open design.
Dimensions and Specifications
The tractor measures 134.25 inches (340 cm) in length, 68.5 inches (173 cm) in width, and 167 cm in height. Available tire configurations included various agricultural sizes, such as 15-34 or 14-34 for the rear, as well as steel wheel options. The cooling system has a capacity of 40 to 44 quarts depending on the specific assembly.
Conclusion
With a total production of 67,418 units, the McCormick-Deering W-9 represents a significant model in the International Harvester 9-series lineup. Its robust construction and multi-fuel capability made it a versatile tool for mid-20th-century agriculture, suitable for operators requiring a reliable, standard-tread tractor for primary cultivation and heavy traction tasks.
