International Farmall 966-1568

In 1971, the revamped Farmall series was introduced, featuring new engines and more powerful hydraulics. Models 966, 1066, 1466, and 1566 were brought to Europe. The 966 had a 6.8-liter engine producing 105 hp. Its counterpart was the 966 Hydro (later Hydro 100), equipped with a hydrostatic transmission. The same turbocharged engine was used in the 1066 model. Above it was the 7.1-liter turbocharged 1466, and in 1974, the more powerful 1566 model was introduced as an upgraded version. At the top of the lineup were the 1468 and 1568, equipped with International's 9.0-liter V8 truck engine. However, the flagship models of the IH lineup were the large tractors 4166, 4366, and 4568.

The 966 had a 16+8 gearbox with a hydraulic power shuttle. The 12" clutch plate was ceramic. In addition to the standard gearbox, the 1066 was available with a hydrostatic transmission. The 1566 had only 3 basic gears and a total of 12+6 gears. The hydraulically engaged power take-off had shafts running at 540 and 1000 rpm, while the 1466 and 1566 had only 1000 rpm shafts. Steering was hydrostatic, and the hydraulic disc brakes were equipped with a booster. There were a total of three hydraulic pumps: for the working hydraulics, steering, and power take-off engagement. The pictures show a model sold in Sweden equipped with a Hara cab.
