Introduction
McCormick-Deering W-12 Standard-Tread Tractor
The McCormick-Deering W-12 is a standard-tread agricultural tractor manufactured by International Harvester in Chicago, Illinois, between 1934 and 1938. It was designed as a versatile, mid-range utility machine for field operations, with a total production run of 3,633 units.
Engine and Performance
The tractor is powered by an International Harvester 4-cylinder, liquid-cooled, vertical I-head engine. With a displacement of 113.1 cubic inches (1.9 liters) and a bore/stroke of 3.00 by 4.00 inches, the engine achieves a rated speed of 1700 RPM. It utilizes a distillate fuel system and an oil bath air cleaner to maintain engine longevity during agricultural use. The firing order is set at 1-3-4-2, and the cooling system has a capacity of 14 quarts (13.2 liters).
Transmission and Drivetrain
Power is transferred through an unsynchronized gear transmission featuring 3 forward gears and 1 reverse gear. The system is engaged via a dry disc clutch. As a two-wheel-drive machine, the W-12 relies on manual steering for operator control within its open station configuration.
