The Brand

Founded in 1919 in Columbus, Indiana by a small engine mechanic, Cummins Engines started with furthering the development of the diesel engine, finding initial commercial success in 1933. Spurred on by the road building boom that occurred in Post WWII America, Cummins quickly become the industry leader with its famous N series engines powering more than half of the heavy equipment being used. With the acquisition of American generator company Onan in 1992, Cummins Inc. became the world’s largest designer and manufacturer of diesel engines ranging from 55- to 2,700-horsepower.
