The tradition of the company Struc Muta in agricultural machinery dates back to 1973. In the 1970s, still under the brand name Gorenje Muta, the company decided to develop a new line of machines to meet the needs of farmers worldwide. This led to the creation of the first professional mower, Combi REX, designed for mowing on challenging terrains, which served as the foundation for the further development of the single-axle tractors KOSOR. The rapid global development encouraged the company to develop a new family of machines under the names Maestral, Profi, Mini, and Kombi.
