D.W. Shifflett sits on an International Farmall "H" purchased shortly after the end of WWII. Tractors were introduced at Rosni in the 1920s, gradually taking purchase in a horse-powered world. In 1963, Rosni's last two teams of horses were sold up the road to an apple orchard. Technology drove population, both equine and human. In 1960, Rosni boasted thirty full-time employees. Twenty years later, following its sale and conversion to a beef operation, Rosni was cultivated by two men using four tractors.
