The 8050 series was introduced at the end of 1995. They featured updated engines equipped with Stanadyne distributor pumps (except for the 8750), which had significantly more torque than before. The 8450’s engine was equipped with a wastegate turbo, and starting from the 8450, a viscous fan was standard. The 8550’s 7.4-liter engine produced 160 hp. In the 8750’s Sigma Power system, engine power increased when the power take-off (PTO) demand exceeded a certain threshold. The 8750 normally had the same 160 hp as the 8550, with a higher power level of 190 hp. The transmission remained the previous 36+36, and the live PTO was standard equipment.
Models 8450–8750 came standard with the more versatile Autocontrol D with oscillation damping, and the front axle was a sturdier industrial axle featuring a engageable friction lock. These models were also available with a long wheelbase if desired. Both the agricultural and industrial axles were manufactured by Dana. The Dana industrial axle is said to be more durable than the Carraro axles used in the HiTech series.
All models had a push-button clutch as standard. The 8550/8750’s standard features included a vertical exhaust pipe and air conditioning. All models except the rare low-speed model 8350 had traffic tractor versions.
For the 2002 model year, only the 8050 and 8150 remained in the lineup, and they received electronically controlled injection pumps. At the same time, the lifting capacity of the 8050 increased to 7 tons.
