The production of tractors in Brno indirectly followed up on the war production of aircraft engines. The blend Zetor originates from the combination of the letter "Zet" in the word "Zbrojovka" with the ending "or" in the word "traktor". Zetor 15 was developed in 1945 by František Musil's construction design company. Altogether 2,215 Zetor 15 tractors were made until 1949 when it was replaced by the more powerful Zetor 25.
