10 years after the start of production of the first Lexion rotary combine, Claas introduced its new flagship, the Lexion 600, in the autumn of 2005. At the same time, it was the most powerful combine in the world and 20-25% more efficient than the Lexion 580. The Lexion 600 was powered by a 16-liter Mercedes V8 engine, with a maximum DIN output of 556 hp. The drivetrain had 2 gears, and the top speed was 30 km/h.

The cutting platform was available in 7.5 or 9.0 meters, and an 11-meter version was introduced in 2009. The standard equipment offered little more than the smaller models, but optional extras included, among others, Cruise Pilot, which automatically adjusted the driving speed by monitoring the threshing drum and engine load. The driving direction could be guided using the familiar Laser Pilot or the new GPS Pilot. Standard was also the Auto Contour II automatic cutting platform height adjustment. Behind the APS acceleration drum and the main threshing drum was the Roto Plus post-threshing drum. The sieving area was slightly larger than that of the 580, and the chopper was a more powerful Special Cut II, which also became standard on the 580. The starting price of the Lexion 600 without the cutting platform was 300,000 euros in Germany.
