Michael M. Sill established Road Machinery & Supplies in 1926. RMS courted heavy equipment suppliers and by 1960 took on statewide representation of Clark wheel loaders, Blaw Knox asphalt pavers and Link Belt cranes and excavators. The company entered the truck equipment business in 1972 and expanded that operation when it became the Midwest distributor for Telelect products and other lines of truck mounted equipment in the Dakotas, Minnesota and Iowa. In 1980, Road Machinery took on representation of Komatsu dozers, loaders and hydraulic excavators. Komatsu is one of the largest manufacturers of construction equipment in the world. RMS started Aspen Equipment, which focuses on general equipment, such as air compressors, light towers, chippers and truck cranes. RMS has grown to become one of the largest Komatsu dealers in the United States, with offices in Minnesota, Iowa, Michigan and Illinois. Road Machinery & Supplies has a location in Des Moines, Iowa.
