In the autumn of 2006, the Premium models of the 6020 series were replaced with corresponding 6030 series models. The new PowerTechPlus engines were equipped with 4-valve technology, a variable vane turbocharger, and exhaust gas recirculation. The extra power began to engage in all models above 15 km/h and was fully available above 21 km/h or in PTO operation. The transmissions remained the same, meaning that the 6530 and 6630 had 24+24 gears, the larger models had 20+20, and all models were available with a parallel version of the stepless AutoPowr.

The cab was significantly modernized, especially in terms of controls. The noise level was 70.6 decibels. The new color display controlled, among other things, electrically operated hydraulic valves (optional), headland automation, and work lights. Overall, more equipment was standard than before. The optional front suspension had been developed and could be stiffened if needed.

In the autumn of 2009, there were minor changes to the engine performance figures. There was more extra power than before, and the range of rated power expanded. Torque values also increased slightly in the 6-cylinder models. At the same time, the listed weights increased. The 6530 was replaced by the 4-cylinder 6534, which in dimensions corresponded to the previous 6-cylinder model.
