# Claas Lexion

Claas Lexion is a series of combine harvesters, manufactured by Claas in Harsewinkel. An American version called Lexion was produced by Claas Omaha Inc. in the United States.

## History

The Lexion was presented in 1995. The first model was the Lexion 480. It has a harvesting capacity of 40 tonnes (39 long tons; 44 short tons) of grain per hour and was at that time the most powerful combine harvester in the world. The Lexion 480 had the same accelerator drum in front of the threshing drum as the Claas Mega, but it came with a bigger threshing drum (600 mm [24 in] diameter and 1,700 mm [67 in] width instead of 450 mm [18 in] diameter and 1,580 mm [62 in] width). Instead of the straw walkers, the Lexion 480 had two separation rotors installed. As a result, the unit ran smoothly and the throughput was much higher than in a conventional straw-walker machine.
From 1999, Claas worked with the US agricultural and construction machinery manufacturer Caterpillar and sold the Lexion combines in North America under the CAT brand. In 2002, Claas took over 50% of the joint venture with Caterpillar and the combine harvester production in the United States. The harvesters produced there were then still marketed as CAT Lexion.
At the 2005 Agritechnica exhibition, Claas presented the Lexion 600, with a cutting width of up to 12 m (39.37 feet), a grain tank capacity of 12,000 liters (330 Bushels) and a performance up to 60,000 kilograms per hour (130,000 lb/h). This was again the most powerful combine harvester in the world. In 2010, Claas presented the Lexion 700. In 2013, Claas introduced new emission standards (Tier 4). The Lexion 8900 released in 2019 has a 581-kilowatt (779 hp) MAN D42 engine that matches the Fendt Ideal 10,000-kilogram (22,000 lb) class 10 combine released in 2020.
