The origin of the Jaguar self-propelled forage harvester dates back to 1969, when Claas bought German machinery manufacturer Bautz. Bautz manufactured mowers, tedders and rakes. Soon after this, Claas bought Speiser, which had developed a tractor-drawn forager for harvesting grass and maize. Claas began the production of its own self-propelled forage harvester series 46 years ago with the Jaguar 60 SF. The 60 SF was first unveiled in June of 1973 and was powered by a 120hp engine.
