In the fall of 2006, the Premium models of the 6020 series were replaced by corresponding models from the 6030 series. The smallest model was discontinued, and power increased across the board. The Tier 3-compliant engines featured all the latest technology, such as turbochargers with variable guide vanes and 4 valves per cylinder. All models now included the additional power feature during transport and PTO operation that had previously been available only in the S models. The transmissions remained unchanged, with 24+24 gears, and a quick-shift automation operating within a basic gear range was optional. Except for the 6230, transmissions were also available in an Eco version, in which 40 km/h was reached at about 1900 RPM. A stepless AutoPowr transmission was still offered.

The cabin had been significantly modernized, especially regarding controls. The noise level was 70.6 decibels. A new color display was used to control, among other things, electrically operated hydraulic valves (optional), headland automation, and work lights. Overall, more equipment was provided as standard than before. The optional front suspension had been developed further and could be stiffened if necessary.

In the fall of 2009, there were slight changes to the engine performance figures. Additional power was increased, the range of rated power expanded to cover a 600 RPM range, but torque figures dropped slightly. At the same time, the reported weights increased significantly.
