M-R-S sold their A-90 123 horsepower model from 1962 to 1963. They continued with several more models until they filed for bankruptcy in the 1980s. Their primary customer was the military, although they also manufactured for the domestic US construction market as well.
M-R-S began with the Mississippi Road Supply Company in 1927. They manufactured four-wheel drive tractors and construction machinery, particularly scrapers. They distributed International Harvester and other construction equipment. Later, M-R-S began assembling large tractors. They used engine and transmission components from other vendors. In 1987, M-R-S filed for bankruptcy.
