Remember seeing those bright orange tractors sitting out in the field? Odds are you were looking at a tractor from Allis-Chalmers. Allis-Chalmers was formed in 1901 as a partnership of several industrial companies in the U.S. Their machinery went on to fuel the industry of America for about 70 years, but they were most easily recognized by their Persian orange tractors and farm equipment. The company dissolved in the 1980s, but it is still an icon of American industry. If you're looking for a historical piece, or for something nostalgic, check out these awesome diecast model replicas.
