Introduction
International Harvester 784: Agricultural Utility Tractor
The International Harvester 784 is a utility tractor produced between 1977 and 1984 in Doncaster, England. Part of the 84 series, it was engineered for versatility, offering multiple configurations including row-crop, utility, and low-profile versions to suit diverse farming environments.
Engine and Performance
The tractor is powered by the International Harvester D-246, a 4.0-liter, 4-cylinder liquid-cooled diesel engine. It operates at a rated speed of 2400 RPM with a compression ratio of 15.5:1. This power plant provides 74 horsepower, intended for general field tasks and heavy-duty agricultural operations.
Transmission and Drivetrain
The 784 offers two transmission options: a standard 8-speed syncromesh transmission or a 16-speed version equipped with the Torque Amplifier. The Torque Amplifier allows for a clutchless power shift between direct drive and a lower speed range, enhancing maneuverability during field work. The tractor is available in both two-wheel and four-wheel drive configurations.
Hydraulics and Hitch
The hydraulic system features an open-center design with a standard pump flow of 13 gpm, which can be upgraded to 15.4 gpm. It includes one or two valves for implement control. The rear Category II three-point hitch is equipped with position and draft control, providing a lift capacity of 3600 lbs.
