McCormick-Deering farm tractors by power
Related brands: International Harvester.
The McCormick name in farm machinery dates back to Cyrus McCormick, who produced the first successful reaper in 1831. McCormick's company was one of the pieces that eventually became International Harvester. International renamed their new 10-20 and 15-30 tractors as McCormick-Deering in 1923. The McCormick-Deering name was used on standard (wide) front tractors for the next three decades, until it was phased out in favor of the International name.
