Toro began in Minneapolis, Minnesota in 1914 by producing engines for the Bull Tractor Company. After branching out into steam engines during World War I, Toro began a focus on golf course and lawn maintenance in the 1920s. In 1986, Toro purchased lawn tractor manufacturer Wheel Horse, acquiring their full line of lawn and garden tractors, plus riding lawn mowers. In the 2000s, Toro focused production on commercial equipment, dropping residential lawn and garden tractors. In 2007, Toro began selling a re-branded line of tractors built by MTD.
