For the year 1991, engine powers were increased: the 307 now had 75 hp, the 308 had 82 hp, and the 309 had 90 hp. The 304 received a turbocharger and its power rose to 70 horsepower. A little later, the 306's power also increased to 75 horsepower and the 305's to 70 horsepower. In the 70 and 75 hp classes, both a 4-cylinder and a turbocharged 3-cylinder were now available. Torque increased by 26% in most models.

The hydraulic outputs were increased to over 70 liters. In the models with more than 75 horsepower, new features included a draft control function for the three-point hitch, automatic sensitivity adjustment of the hitch, and an electrical system with centralized precious metal connectors.

From the lineup, the 304, the 308 enhanced to 86 horsepower, and the 309 continued until 1998, while production of the other models ended at the introduction of the new Farmer series in 1993. The engines of these models were also replaced with new versions, whose changes and torque specifications can be found in the presentation of the new series.
