Introduction
J.I. Case 20-40 Standard-Tread Tractor
Produced between 1912 and 1919 in Racine, Wisconsin, the J.I. Case 20-40 represents a significant period in early 20th-century agricultural mechanization. This standard-tread tractor was designed for heavy-duty field work, utilizing a large-displacement engine and a durable steel-framed construction.
Engine and Performance
The tractor is powered by a 2-cylinder, liquid-cooled engine with a displacement of 17.7 liters (1082 ci). It features a bore and stroke of 222 x 229 mm and operates at a rated speed of 475 RPM. The engine runs on kerosene and is started via a hand-crank mechanism. Notably, the engine displacement was increased by approximately 20% around 1916 through an increase in bore size, though the official power rating of 44 hp remained unchanged.
Transmission and Mechanical Layout
Equipped with a J.I. Case gear-type transmission, the machine provides two forward gears and one reverse gear. It utilizes a two-wheel drive configuration managed through manual steering. The drivetrain is designed for high-torque applications rather than speed, reflecting the typical requirements of the era.
Dimensions and Construction
The 20-40 is a substantial machine, weighing 13,900 lbs (6,305 kg) with an overall length of 177 inches (449 cm) and a width of 100 inches (254 cm). It rides on steel wheels, specifically 38x8-inch front tires and large 66x20-inch rear tires. The operator station is open by design, with a four-post steel cab offered as an optional configuration for improved operator environment.
Conclusion
With 4,465 units produced, the J.I. Case 20-40 served as a primary power source for large-scale farming operations in the 1910s. Its heavy construction and high-displacement engine make it a notable example of the transition toward mechanized agriculture, intended for sustained pulling tasks rather than maneuverability.
