Introduction
Minneapolis 25-50 Standard-Tread Tractor
The Minneapolis 25-50 is a standard-tread agricultural tractor produced between 1911 and 1912 by the Minneapolis Threshing Machine Company in Hopkins, Minnesota, USA. It represents an era of heavy-duty early 20th-century agricultural machinery designed for high-torque stationary and field work.
Engine and Performance
The tractor is powered by a liquid-cooled, four-cylinder engine with a displacement of 904.8 cubic inches (14.8 liters). Engineered to run on kerosene, the engine operates at a rated speed of 550 RPM. Starting is achieved via a manual hand crank. The machine generates 25 horsepower (18.6 kW) at the drawbar and 50 horsepower (37.3 kW) at the belt, making it capable of both heavy traction tasks and powering stationary threshing equipment.
Transmission and Mechanical Layout
The drivetrain features a manual gear transmission providing two forward speeds and one reverse gear. It utilizes a two-wheel-drive configuration controlled by a manual steering system. The tractor is built with a steel canopy to provide basic protection for the operator.
Dimensions and Construction
With a total weight of 17,000 lbs (7,711 kg), the Minneapolis 25-50 relies on its substantial mass to maintain traction. It is equipped with steel rear wheels measuring 85x24 inches, typical of the construction standards for agricultural tractors during this period.
Conclusion
The Minneapolis 25-50 is a heavy-duty tractor suited for early 20th-century farming operations that required significant belt power for processing crops alongside traditional field traction. Its robust steel construction and large displacement engine reflect the engineering priorities of the pre-World War I era.
