McCulloch Farm tractors by factory

McCulloch Motors was a small-engine and outdoor tool manufacturer. Founded in Milwaukee in 1943 by Robert McColloch, McCulloch had great success with chainsaws using their lightweight engines. The company expanded into outdoor tools, outboard motors, and aviation. In the 1960s, McCulloch became the first US importer of Kubota tractors, re-branding them with the McCulloch name. By the 1970s, Kubota had entered the US market under their own brand. McCulloch is now owned by Husqvarna.
