The Farmall 856 is a 2WD or 4WD row-crop tractor from the 56 series. This tractor was manufactured by Farmall (a part of International Harvester) from 1967 to 1971.
The Farmall 856 is equipped with one of two engines: a 6.7 L (406.9 cu·in) six-cylinder diesel engine or a 4.9 L (301.0 cu·in) six-cylinder gasoline/LP-gas engine and one of two transmissions: a sliding gear transmission with 8 forward and 4 reverse gears and dry disc clutch or a two-speed power shift transmission with 16 forward and 8 reverse gears and dry disc clutch.
The tractor could be equipped with the following engines:
- International Harvester D-407. It is a 6.7 L, 6,668 cm2, (406.9 cu·in) six-cylinder natural aspirated diesel engine with 110.0 mm (4.33 in) of the cylinder bore and 117.0 mm (4.61 in) of the piston stroke. The compression ratio rating is 17.0:1. This engine produced 96.3 PS (70.8 kW; 95.0 HP) at 2,400 rpm of PTO output power.
- International Harvester C-301. It is a 4.9 L, 4,932 cm2, (301.0 cu·in) six-cylinder natural aspirated gasoline/LP-gas engine. The cylinder bore is 97.0 mm (3.82 in) and the piston stroke is 112.0 mm (4.41 in). The compression ratio rating is 7.7:1 for gasoline version or 8.8:1 for LP-gas version. This engine produced 96.3 PS (70.8 kW; 95.0 HP) at 2,400 rpm of PTO output power.
The Farmall 856 is equipped with hydrostatic power steering, independent hydraulic disc brakes, open operator station or Cab (optional) with heat and A/C and 159.0 liters (42 US gal.; 35 Imp. gal) fuel tank for gasoline and diesel fuel or 181.7 liters (48 US gal, 40 Imp. gal) for LPG.
