Introduction
Twin City 21-32: Standard-Tread Agricultural Tractor
Produced between 1928 and 1938 in Minneapolis, Minnesota, the Twin City 21-32 is a standard-tread tractor designed for mid-range agricultural operations. With 7,229 units manufactured, this machine represents a significant part of early 20th-century tractor development.
Engine and Performance
The tractor is powered by a liquid-cooled, 4-cylinder inline engine with a displacement of 381.7 cubic inches (6.3 L). Designed to operate on kerosene, the engine maintains a rated speed of 1075 RPM and delivers 35 horsepower. The cooling system has a capacity of 36 quarts (34.1 L) to ensure thermal stability during prolonged field work.
Transmission and Drivetrain
The drivetrain features a two-wheel drive configuration paired with a manual steering system. Power is transmitted through a dry disc clutch. Operators could choose between two transmission configurations: a 2-speed gear set providing two forward and one reverse gear, or a 3-speed gear set providing three forward and one reverse gear, allowing for speed adjustments based on specific agricultural requirements.
Dimensions and Chassis
The Twin City 21-32 is built on a frame with an 84-inch (213 cm) wheelbase, contributing to its overall length of 137 inches (347 cm) and height of 66 inches (167 cm). The machine has a total operating weight of 5,880 lbs (2,667 kg). It is equipped with steel agricultural wheels, specifically 34x5.75 front tires and 50x12 rear tires, characteristic of the era's standard-tread tractors.
Conclusion
The Twin City 21-32 is a representative example of 1930s engineering, serving as a reliable utility tractor for farmers of that period. Its combination of a high-displacement engine, manual controls, and robust steel-wheeled chassis provided the necessary traction and power for standard agricultural tasks.
