Introduction
Minneapolis 20-40 Standard-Tread Tractor
The Minneapolis 20-40 is a standard-tread agricultural tractor manufactured by the Minneapolis Threshing Machine Company in Hopkins, Minnesota, between 1914 and 1919. Designed for heavy-duty field operations, this machine represents a significant example of early 20th-century agricultural engineering.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled engine designed to operate on kerosene. With a displacement of 727.1 cubic inches (11.9 liters) and a bore/stroke ratio of 5.75 by 7.00 inches, the engine reaches its rated performance at 650 RPM. The engine is started via a hand crank mechanism. It provides a claimed drawbar power of 20 hp (14.9 kW) and a belt power of 40 hp (29.8 kW), which allowed it to pull 4 to 6 14-inch plows.
Transmission and Mechanical Layout
The drivetrain consists of a manual gear transmission offering two forward speeds and one reverse gear. This two-wheel drive machine utilizes manual steering for operator control. The rear axle measures 3.4375 inches (87 mm) in diameter, providing the necessary structural integrity for the tractor's 12,000 lbs (5,443 kg) weight.
Dimensions and Undercarriage
The tractor measures 167 inches (424 cm) in length, 96 inches (243 cm) in width, and 110.5 inches (280 cm) in height. To manage its weight and provide traction in field conditions, the unit is equipped with 66x20 steel agricultural rear wheels.
Conclusion
The Minneapolis 20-40 is a heavy-duty tractor engineered for primary tillage and intensive belt-driven tasks. Its robust construction and kerosene-fueled engine made it a staple for large-scale farming operations during the 1910s, remaining a noteworthy machine for collectors and historians of agricultural machinery.
