John Deere & Co.

John Deere & Co., based in Moline, Illinois, began producing combine harvesters in 1927 to harvest and thresh farm crops. The company was established in 1837 and grew to become the global leader in manufacturing agricultural machines. In addition to its standard combine harvester, it produced a sidehill harvester that allowed the combine to navigate steep hillsides to harvest crops.
