McCormick-Deering T-40

The McCormick-Deering T-40 tractor was a heavy-duty workhorse equipped with a 298.2 cubic inch (4.9 L) gasoline-powered 6-cylinder liquid-cooled engine by International Harvester. Operating at a rated speed of 1750 RPM, the engine's size and characteristics suggest it was suitable for demanding tasks. This tractor had a dry disc clutch, a gear transmission with 5 forward and 1 reverse gears, and a centrifugal governor. The engine featured an oil-washed wire filter air cleaner, pressure lubrication, and a Zenith Model 50-AY-12 carburetor (Size 1-1/2"). The length, width, and height of the T-40 are 141 inches, 65 inches, and 65 inches, respectively, and it has an operating weight of 12,770 pounds. The independent test results confirm the T-40 had a TraclTayer drive type, an enclosed gear chassis, and track measurements of 19.106 feet length, 16" face, with 38 integral cleats (2" high x 16" wide) per track. The coolant capacity of the engine is 48 quarts, helping to maintain optimal operating temperatures during extensive use. This model's specifications indicate it was built to endure and perform in a variety of conditions.
