Steyr 8100-8130

In the spring of 1978 Steyr introduced its entirely new 8000-series models, the 8100 (85 hp) and the 8120 (100 hp). Both were powered by a small six‐cylinder 5.2 L engine, turbocharged on the 8120. The standard transmission was a fully synchronized 12+4 unit built by Deutz. An optional 15+5 gearbox added one extra gear at the top of each of the three ranges, allowing a road speed of 30 km/h. The shift levers were mounted on the right side, and the clutch disc measured 350 mm in diameter. Lift capacity was a hefty 4 300 kg for the time. Instead of the drum brakes Steyr usually favored, these tractors came with dry disc brakes, and front‐axle disc brakes were available as an option. Four‐wheel drive was implemented via a central axle and could be engaged on the move. Although they allowed a 50° steering angle, the turning circle was not especially tight. The front axle was made by Sigen; the rear axle by Deutz. The 8100 featured draft control, while the 8120 had position sensing.

In 1984 engine outputs were increased and the model numbers were changed to 8110 and 8130. The transmission now had six main gears, enabling a road speed of 40 km/h. As an option Steyr offered a hydraulic Steyr-Matic rapid-shift system, bringing the total to 36+12 gears. A front-axle differential lock became standard.

In 1987 the two-wheel-drive versions were dropped. A new SK 2 “Superkomfort” cab was introduced, with an interior noise level of 79 dB. The cab’s framework remained the same, but the visible change was the adoption of full-glass doors. Lift capacity was raised to 5 800 kg, and an electro-hydraulic lift control unit became available. In 1992 the 8130’s output was increased to 115 hp. The 8110 and 8130 were the last remaining models in the 8000 series.
