The name "Jaguar" doesn't originate from Claas itself, but originally from the Wilhelm Speiser company in Göppingen.
Forage harvesters, such as the "Scampolo," the "Super," and the "Jaguar," were already being produced there in the 1950s.
At the end of the 1960s, the company was sold to Claas, and the name "Jaguar" was adopted directly.
