Zetor is a tractor manufacturer in the Czech Republic. Until 1990 it was a subsidiary of Zbrojovka in Brno. The name itself arose from merging "Zet" from the logo of Zbrojovka and the last two letters of the word tractor. Zetor has pioneered various innovations throughout its history. It was among the first tractor companies to produce fully integrated safety cabs with insulated, rubber-mounted suspension. While Zetor is a Czech company, versions of its tractors are assembled in numerous countries including Argentina, Burma (Myanmar), India, Iraq, Uruguay and Zaire (Congo-Kinshasa).
