In the fall of 1976, the 66 series was replaced by the 86 series in the American lineup. The most important innovation was a new quiet and air-conditioned factory-installed Control Center cab, which was positioned further forward than before. V8 engines were discontinued, and part of the lineup was now also available with four-wheel drive. The brakes in most models were now oil-immersed and external.

Models 886, 986, 1086, 1486, and 1586 were introduced to Europe, available both as rear-wheel and four-wheel drive. The transmission in the smaller models was synchronized with a 16+8 hydraulic quick-shift. The 1586 (180 hp) had only 3 basic gears instead of 4, with a total count of 12+6. The clutch was reinforced, and the clutch disc was increased to 14 inches starting from the 1086. An optional small digital multifunction display showed, among other things, the driving speed and PTO speed. For an American tractor, the 86 was rather short.

The smallest models in the lineup were the 5.1-liter 686 and Hydro 86. The 886 had a displacement of 5.9 liters, while the 1086 had a 6.8-liter turbocharged engine with a power of 148 hp. The engines of the 986 and Hydro 186 were 7.1 liters. The same engine was turbocharged in the most powerful models, the 1486 and 1586. The large frame, articulated models started from this size upward. At the top was the 13-liter turbocharged 4586.
