Introduction
Wallis K 15-25 Standard-Tread Tractor
The Wallis K 15-25 is a standard-tread agricultural tractor manufactured between 1919 and 1923 by Wallis, a division of J.I. Case Plow Works, in Racine, Wisconsin, USA. This model represents a significant period in early 20th-century tractor development, positioned between the Cub Junior and the OK 15-27 series.
Engine and Performance
The tractor is powered by a liquid-cooled, 4-cylinder gasoline engine with a displacement of 326.3 cubic inches (5.3 liters). With a bore and stroke of 4.25 by 5.75 inches, the engine produces 27 horsepower at a rated speed of 900 RPM. The engine utilizes a hand-crank starter, typical for the engineering standards of its production era.
Transmission and Drive
The Wallis K 15-25 features a two-wheel drive configuration. Its mechanical transmission system provides 2 forward gears and 1 reverse gear, allowing for basic speed control during field operations. The steering is entirely manual, requiring direct operator input for maneuverability.
Dimensions and Weight
Designed as a standard-tread machine, the tractor measures 132 inches (335 cm) in length, 61 inches (154 cm) in width, and 65 inches (165 cm) in height. It maintains a operational weight of 3,500 lbs (1,587 kg), providing the necessary ballast for its intended agricultural tasks.
Conclusion
The Wallis K 15-25 is a representative example of early American tractor design, intended for standard agricultural traction work. Its mechanical simplicity and robust construction reflect the manufacturing priorities of the post-World War I era.
