Introduction
Avery 25-50 Standard-Tread Tractor
The Avery 25-50 is a standard-tread agricultural tractor produced between 1916 and 1923 in Peoria, Illinois, USA. Designed for heavy-duty field work, this two-wheel drive machine represents a significant example of early 20th-century American tractor engineering.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled opposed horizontal engine designed to operate on kerosene. With a displacement of 1061.9 cubic inches (17.4 L) and a bore/stroke of 6.50 x 8.00 inches, the engine delivers 55 hp at a rated speed of 700 RPM. The cooling system is notably large, featuring a 220-quart (208.2 L) coolant capacity to manage thermal loads during sustained operation.
Transmission and Mechanical Layout
The Avery 25-50 utilizes a two-wheel drive system to transfer power to the ground. The drivetrain features an unsynchronized gear transmission, providing the operator with two forward gears and one reverse gear for basic maneuvering and field tasks.
Dimensions and Construction
Built for stability and heavy traction, the tractor has an operating weight of 12,500 lbs (5,670 kg). It measures 176 inches (447 cm) in length, 90.5 inches (229 cm) in width, and 108 inches (274 cm) in height. The machine is equipped with steel wheels, specifically 38x10 front wheels and 69x20 rear wheels, which were standard for the era's agricultural applications.
Conclusion
With its substantial weight and large displacement engine, the Avery 25-50 was engineered for heavy draft requirements typical of early 20th-century farming. Its design reflects the period's reliance on kerosene power and robust, simplified mechanical components.
