The company expanded its factory after the war, consolidated its position on the market and began exporting. Hürlimann introduced the D600 tractor (70HP) during the 1950s, which was especially popular in Argentina (a significant portion of the production was earmarked for South America). In 1950 Hürlimann patented a motorised harrow with excellent performance capacities: the documented production was 6,162 m2 harrowing per hour .
