Introduction
Hart-Parr 18-36 Agricultural Tractor
The Hart-Parr 18-36 is a standard-tread tractor produced between 1926 and 1930 in Charles City, Iowa, USA. Designed for agricultural operations, this machine represents the mechanical engineering standards of the late 1920s.
Engine and Performance
The tractor is powered by a 2-cylinder, liquid-cooled gasoline engine with a displacement of 501 cubic inches (8.2 liters). It features a bore and stroke of 171 x 178 mm and operates at a rated speed of 800 RPM. The fuel system utilizes a Stromberg MB3 carburetor, while the intake air is cleaned by a dry centrifugal air cleaner, a configuration designed for the operational requirements of the era.
Transmission and Mechanical Layout
The drivetrain consists of a gear-type transmission offered in two configurations: either 2 forward and 1 reverse gear, or 3 forward and 1 reverse gear. Power is transferred via a dry disc clutch. The tractor is a two-wheel drive model featuring manual steering and an open operator station.
Dimensions and Construction
The machine has a base weight of 6100 lbs (2766 kg). It is equipped with steel agricultural wheels, measuring 28x5 at the front and 51x12 at the rear. Specific variants, designated as New Zealand and Australia Specials, were adapted for arid climates, featuring modified air filtration systems and a vertically oriented exhaust pipe.
Conclusion
The Hart-Parr 18-36 is a representative example of early 20th-century agricultural machinery, suited for general heavy-duty traction tasks. Its robust, liquid-cooled engine and modular transmission options made it a versatile tool for farmers during its period of manufacture.
