Muir-Hill produced four-wheel drive tractors in England during the 1960s and 1970s. The company originally started in the 1920s as a maker of railroad equipment, dump trucks, and hydraulic loaders. Their first tractor was manufactured in 1969, but production of tractors ceased in the mid-1980s. The Muir-Hill brand is now owned by Lloyd Loaders, which offers parts and services for these tractors.
