Introduction
Denning Model E Agricultural Tractor
The Denning Model E is a standard-tread tractor produced between 1916 and 1918 in Cedar Rapids, Iowa, USA. As a piece of early 20th-century American agricultural machinery, it represents the transition toward mechanized farming solutions during that era.
Engine and Performance
The tractor is powered by a liquid-cooled, four-cylinder Waukseha gasoline engine. With a displacement of 202 cubic inches (3.3 liters) and a rated RPM of 1200, the engine provides a claimed belt power of 18 hp (13.4 kW). This power output is designed for steady agricultural tasks, including the operation of up to two plows.
Transmission and Drive System
The Model E utilizes a friction disc transmission system, offering six forward and six reverse gears. This configuration allows for a degree of speed control required for field work. The tractor features a two-wheel drive system and is equipped with manual steering, reflecting the mechanical simplicity of its time.
Dimensions and Construction
Built with a focus on stability, the tractor weighs 3,600 lbs (1,632 kg). Its physical footprint measures 120 inches (304 cm) in length, 56 inches (142 cm) in width, and 61 inches (154 cm) in height. The machine is supported by 46x10 steel rear agricultural wheels, which were standard for the period to provide necessary traction in soft soil conditions.
Conclusion
The Denning Model E is a representative example of early American tractor design. With its 20 hp engine and manual configuration, it served as a utility machine capable of handling basic plowing and belt-driven operations, making it a significant reference for historical agricultural technology.
