The International Harvester 784 is a 2WD/4WD utility tractor from the 84 series. This tractor was manufactured by the International Harvester in Doncaster, England from 1977 to 1984. The IH 784 is equipped with 4.0 L, four-cylinder diesel engine and synchromesh transmission (8 forward and 4 reverse gears) with dry disc clutch. The IH 784 was available in three versions: row-crop, low-profile, and utility tractor. The front axle and rear wheel were the primary difference between the three versions of the 784. All three versions had significant differences in the front and rear axles.

The compression ratio rating is 15.5:1. This engine produced 68.4 PS (50.3 kW; 67.5 HP) at 2,400 rpm of maximum output power.
The International Harvester 784 is equipped with hydraulic power steering, independent hydraulic wet disc brakes, open operator station with ROPS (standard), except on low-profile, canopy as an option, and 76 liters (20.1 US gal.; 16.7 Imp. gal) fuel tank.
