International Harvester 784

The International Harvester 784 was produced from 1977 to 1984 as part of the 84 Series utility tractors. It was built in Doncaster, England and was available in three configurations: row-crop, utility, and low-profile, differing mainly in front axle and rear wheel. It features a 4.0L 4-cylinder liquid-cooled diesel engine, with power outputs around 69 to 81 hp (estimated). Transmission options include an 8-speed syncromesh and a 16-speed two-speed power shift with torque amplifier. The tractor has two- or four-wheel drive, power steering, independent hydraulic wet disc brakes, and standard ROPS except on low-profile models. Fuel capacity is 20 gallons, and hydraulic system capacity is 9 gallons. Dimensions and weights vary by configuration, with shipping weights ranging from 5850 to 7108 lbs. The 784 is part of a series including the 684 and 884 models.
