Custom Manufacturing built several models of tractors in the post-World War II period using Chrysler engines and transmissions. Custom tractors produced tractors under the Montgomery Ward, Lehr Big Boy, and (in Canada) the Rockol and Regal brands. Founded in Shelbyville, Indiana in 1944, the company was sold and production moved to Hustisford, Wisconsin in 1952. Production continued in Hustisford until 1954 when the company's assets were sold to a Mexican firm.
