The third-generation Lexion models were introduced in the autumn of 2019. Claas stated that the update was the biggest product development project in its history. There were three 5-rotor models and four 6-rotor models. The engines were Mercedes-Benz 7.7- and 10.7-liter units, except for the largest model which had a 12.4-liter MAN engine. The engines met Stage 5 emission requirements using urea injection and a particulate filter. The Dynamic Power function adjusted the engine to a more economical power curve when full power was not needed. The radiator fan speed was also automatically adjusted according to cooling needs. The drivetrain now allowed a speed of 40 km/h and used fewer belts than before.

The threshing drum diameter had increased to 75 centimeters. In front of the threshing drum was a 45-centimeter acceleration drum and behind it a 60-millimeter separation drum. The straw walker sections could be easily removed in blocks from the side of the combine. A new feature in the rotor combines was the Jet Stream fan system, which blew some of the short straw away already before the sieves. The sieve adjustment was electric. Because of the larger threshing drums, the rotors were shorter than before. The threshing system was promised to be 25% more efficient than earlier models.

The cab was more spacious and quieter (72 dB). The Cebis touchscreen user interface had been redesigned. Important functions still had separate buttons. If equipped with automatic steering, control was handled via a separate S10 terminal. Like new combines from other brands, Claas now also offered remote connection to service. The unloading pipe’s swivel angle was increased to 105 degrees. Larger tires were available for the biggest models. Terra Trac tracked versions were available for models 5500, 6700, 6800, and 6900.
