For Sale: 1946 McCormick Deering Orchard in Saint Louis, Missouri

Founded in 1902 through the merger of McCormick Harvesting Machine Company, Deering Harvester Company, and three other smaller manufacturers, International Harvester (IH) quickly became a dominant force in agricultural equipment. Known for its pioneering innovations, IH introduced a range of tractors and implements designed to meet the diverse needs of farmers worldwide. With a legacy of engineering excellence and a reputation for durability, IH produced iconic machines such as the McCormick-Deering W series, which combined practicality with the sleek styling of industrial designer Raymond Loewy.
Introduced as part of the McCormick-Deering W series, the O-4 retained the signature Raymond Loewy styling seen across the International Harvester lineup. Like its W-series siblings, it eschewed the adjustable axles and high clearances of IH's row-crop tractors in favor of fixed wheel widths and a lower profile, aligning with the needs of orchardists, plowing, and general-purpose work.
The McCormick-Deering O-4 is a specialized variant of the W-4 standard tractor, designed explicitly for orchard applications. Its narrower profile and unique design made it ideal for maneuvering between tight rows of trees. The tractor features a sleek, streamlined hood with a lowered air intake and exhaust to prevent damage to low-hanging branches, along with smooth shielding over the rear wheels and side panels enclosing the engine to avoid snagging on foliage.
Powered by the International Harvester C152 2.5L four-cylinder gasoline engine, the O-4 delivers 27.5 horsepower and utilizes a five-speed sliding-gear transmission, ensuring reliable performance in orchard work. The rear power takeoff (PTO) adds versatility for driving implements, while optional features such as an electric starter and headlights enhance functionality.
The O-4 presented here has been handsomely and professionally restored from the ground up. This example features streamlined bodywork, which, along with the special narrow track width, was designed to protect delicate fruit trees and grapevines while negotiating the confines of orchards and vineyards. Superbly detailed and correctly finished in McCormick-Deering's signature red paint with authentically reproduced factory decals and medallions, the restoration also includes correct new gauges and a new wiring harness.
With a wheelbase of 66.75 inches and a weight of 4,300 pounds, the O-4 was built with a low center of gravity for stability on uneven orchard terrain. The tractor rides on 6.00-16 Champion Guide Grip 3 Rib front tires and 13.6-26 Firestone Traction Field rear tires, providing excellent traction.
This 0-4 McCormick represents the pinnacle of post-war agricultural design, blending utility with classic International Harvester aesthetics. Its marvelous streamlined bodywork transcends its intended function, making this McCormick just as well-suited to a world-class collection as it would be to working the fields. Whether you're a collector of vintage tractors or seeking a working piece of agricultural history, the McCormick-Deering O-4 is a standout machine that embodies the innovation and craftsmanship of its era.
