CLAAS is an agricultural machinery manufacturer based in Harsewinkel, Germany, in the federal state of North Rhine Westphalia.

The product range also includes tractors, balers, mowers, rakes, tedders, silage trailers, wheel loaders, telehandlers and other harvesting equipment as well as farming information technology.

[2] CLAAS employs around 11,500 employees worldwide and reported a turnover of roughly 3.9 billion euros in the 2019 financial year.

After their return from the First World War, the Claas brothers and sisters moved their company to Harsewinkel in 1919, where they bought a disused hard stone factory and continued production.

With the acquisition of a majority stake in Renault Agriculture in 2003, CLAAS expanded its product range to include standard tractors.

[6] With the construction of the new development center for electronics in Dissen, Lower Saxony, CLAAS set the course for another important future field in 2017: the digitalization of agriculture.

Experts have condemned Claas for indirectly enabling Russia’s violations of international humanitarian law through its continued presence.

[10] Recent Russian legislation requires companies operating in the country to support military mobilization efforts, raising concerns that Claas may be contributing, directly or indirectly, to Russia's war against Ukraine.

[11] This situation also poses significant reputational and legal risks for the company, particularly under Germany's Supply Chain Due Diligence Act, which mandates corporate accountability for human rights impacts.

The LEXION 8900 has a maximum output of 790 hp and is available with tyres or crawler tracks (TERRA TRAC) on the front axle.

[14] In July 2023, CLAAS unveiled the new EVION 400 Harvester Range, a Replacement for the previous AVERO and smaller TUCANO models.

Since 2019, CLAAS has offered an optional track system for the AXION 900 series, instead of the rear wheels, called TERRA TRAC providing an exceptionally smooth operation with reduced ground compaction.

To the seaports of Bremen and Hamburg as well as to Southeast and Eastern Europe (especially Poland, Romania and former CIS states) rail transport is predominant.

The importance of rail traffic is reflected in the fact that as early as 1967, a 3.1-kilometer-long connecting railway was built, leading from the Ibbenbüren – Gütersloh line of the Teutoburger Wald-Eisenbahn (TWE) to the company's own Harsewinkel-West works station.

[19] CLAAS's facilities in Bad Saulgau develop, test and manufacture forage harvesting machines and attachments.

[21] All CLAAS tractor models except of the XERION are manufactured at the Le Mans factory, two hours' drive southwest of Paris.

With the growing business in the US, the spare parts department in Columbus, which is responsible for the entire US and Canada, has also been greatly expanded.

The plant is located in the largest grain growing areas in the US and was initially operated in cooperation with Caterpillar – since 2002 fully owned by CLAAS.

With the start of the production of the new LEXION model series for the North American market at the factory in Omaha, Nebraska color scheme changed to the typical CLAAS green-white-red.

This made CLAAS the first major agricultural engineering manufacturer to operate its own production facilities in Russia.

The production facility in Krasnodar is designed for a capacity of 1,000 machines per year and aims to develop into a local center of excellence in agricultural engineering.

The CROP TIGER combine harvester is mainly produced in the Chandigarh plant in both wheeled and TERRA TRAC tracked versions.

With the crawler tracks, this machine is particularly suitable for wet soils and is therefore sold in Southern India, Sri Lanka, South Korea and other South-East Asian countries.

The wheeled version of the CROP TIGER is mainly used in dry conditions such as in Northern India, the Middle East and Africa.
