Introduction
Eagle Manufacturing H 20-40 Standard-Tread Tractor
The Eagle Manufacturing H 20-40 is a vintage standard-tread tractor produced between 1922 and 1930 in Appleton, Wisconsin, USA. Designed for heavy-duty agricultural labor, this machine represents the mechanical engineering standards of the early 20th century, focusing on high-displacement power and robust construction.
Engine and Fuel System
The tractor is powered by a liquid-cooled, 2-cylinder 4-valve engine with a displacement of 1005 cubic inches (16.5 liters). Operating at a rated 450 RPM, the engine utilizes a Schebler carburetor and is designed to run on kerosene. The engine is started via a traditional hand-crank mechanism.
Transmission and Drivetrain
The H 20-40 features a manual transmission configuration with two forward gears and one reverse gear. Power is delivered to the wheels through spur gear final drives, supporting the machine's two-wheel drive capability. Steering is manual, requiring operator input for maneuverability.
Performance and Dimensions
The tractor delivers a claimed 20 hp (14.9 kW) at the drawbar and 40 hp (29.8 kW) at the belt, suitable for stationary machinery tasks. It weighs 7840 lbs (3556 kg) and measures 147 inches in length. It is fitted with 52x18 steel agricultural wheels, which provided the necessary traction for field operations of that era.
Conclusion
The Eagle Manufacturing H 20-40 is a representative example of early American agricultural technology. Its high-displacement engine and substantial steel-wheeled chassis made it a capable tool for primary tillage and belt-driven farm work during the 1920s.
