In 1946, Robert changed the name of his company to McCulloch Motors Corporation. The company then moved from Wisconsin to California, where McCulloch Motors produced its first chainsaw, a two-man model named 5-49. The real breakthrough came in 1949. That year, McCulloch revolutionized the whole chainsaw industry by introducing a light one-man chainsaw called the 3-25. North American woodworking would never be the same again.
