The M had been in development for several years during World War II prior to its introduction in 1947. The M replaced the H, L, and LA models. Three additional variants; the MT tricycle, MC crawler model, and MI industrial model were also built. The M was the first tractor to be produced at Deere's new Dubuque factory. It was the first to use Deere's Touch-O-Matic hydraulic system. PTO and electric starting were standard features.
