In 1922, the revolutionary three-plow, transmission-powered International 15-30 was renamed the McCormick-Deering 15-30.
In early 1923, this was the only International Harvester tractor model, while the International 8-16 double-plow,
The 3 plow Titan 10-20 and 4 plow International 15-30 with chain drive have been discontinued.
The McCormick-Deering 10-20 transmission was not released until later in 1923.
In export markets, the tractor continued to be branded International, Deering, or McCormick.
Over the course of production, the nickname 15-30 became increasingly popular and widely known to farmers in most regions, especially in the United States and Canada.
