REO Lawn tractors by power

REO manufactured a line of lawn mowers from the 1940s until 1970. The REO Motor Car Company was an early manufacturer of automobiles and trucks, founded by Ransom Olds. REO began building lawn mowers in 1946 and had success in the 1950s with walk-behind reel mowers powered by their own small engine. The company was broken up in 1954 and the lawn mower group ended up with Wheel Horse in 1963. Wheel Horse continued to use the REO brand until 1970.
