Introduction

International Harvester Farmall 450

The International Harvester Farmall 450 is a row-crop tractor produced between 1956 and 1958 in Rock Island, Illinois, USA. Designed as a versatile agricultural machine, it was built in a total of 18,305 units and features a two-wheel drive configuration.

Engine and Performance

The tractor is powered by an International Harvester 4-cylinder, liquid-cooled, vertical I-head engine with a displacement of 281 cubic inches (4.6 liters). It operates at a rated RPM of 1450 and features a compression ratio of 8.35:1. The engine, capable of producing 63 horsepower, utilizes LP gas and requires a coolant capacity of 28 quarts (26.5 liters) along with an oil capacity of 9 to 8 quarts depending on specific configuration.

Transmission and Drivetrain

The drivetrain utilizes the International Harvester Torque Amplifier transmission, which is a partial power shift system providing 10 forward gears and 2 reverse gears. Power is transferred through a dry disc clutch. The tractor is equipped with a rear PTO type of 540 RPM (1.375 shaft), with an optional independent PTO system available.

Hydraulics and Hitch

Hydraulic functionality is provided by the Hydra-Touch system, which supports between 1 and 3 valves for implement control. Attachment of implements is facilitated by the proprietary IH Fast Hitch system, designed to streamline the coupling of row-crop equipment.
