Johann Georg Fendt, the firm’s founder, gave his first tractors the name ‘Dieselross’ (literally: Diesel Steed). Fendt tractors kept their trade name from the end of the 1920s up to the 1960s, and it proved a highly effective one, suggesting in a word the enormous power the tractors generated and at the same time a kind of friendly familiarity (after all, there are horses on every farm!). Even the 1920s version (the classic Dieselross) had six-horse-power; the post-war F20 (hence the name) twenty.
