Introduction
Parrett H 12-25 Tractor
The Parrett H 12-25 is a two-wheel-drive agricultural tractor manufactured by Parrett in Chicago, Illinois, between 1918 and 1920. It represents a period of transition in early 20th-century mechanization, designed to replace animal labor with internal combustion power for primary tillage tasks.
Engine and Fuel System
The tractor is powered by a 4-cylinder Buda engine with a displacement of 312 cubic inches (5.1 liters). It features a bore and stroke of 4.25 by 5.50 inches (108 x 140 mm). The engine is liquid-cooled and designed to operate on kerosene. Fuel delivery is managed by a 1.25-inch Kingston carburetor, while an air intake system utilizing a water bath air cleaner provides basic filtration for the engine.
Transmission and Drivetrain
The drivetrain consists of a two-wheel drive system coupled with an unsynchronized gear transmission. The gearbox provides two forward speeds and one reverse gear, which was a standard configuration for tractors of this era to accommodate basic field operations.
Performance and Capacity
The Parrett H 12-25 was rated for a drawbar power of 12 hp (8.9 kW) and a belt power of 25 hp (18.6 kW). This power output allowed the machine to pull a configuration of three 14-inch plows, serving as a primary implement for soil cultivation.
Physical Specifications
The tractor weighs approximately 5,200 lbs (2,358 kg). Its physical footprint measures 146 inches (370 cm) in length, 72 inches (182 cm) in width, and 67 inches (170 cm) in height. It is equipped with 60x10 steel rear wheels, typical for the traction requirements of the period. The operator interface consists of an open station configuration.
Conclusion
The Parrett H 12-25 was a functional utility tractor suited for mid-sized farm operations during the late 1910s. Its robust construction and ability to power belt-driven machinery alongside field tillage made it a versatile tool for farmers transitioning to mechanized agriculture.
