Ever wonder about the origins of the mighty motor grader? Look to Minnesota and Caterpillar. Russell Grader Manufacturing Co. of Minnesota had been producing pulled implements for ditching and road contouring since 1903. The first Russell self-propelled motor grader was launched as the Motor Patrol No. 1 in 1920. In 1928, Caterpillar purchased Russell, and in 1931, came out with the first motor grader as we know it. Originally called “auto patrols,” the new machines were a milestone in the road maintenance industry. It’s cutting edge features were soon adopted by the entire industry!
