Simplicity Manufacturing Company is a company based in Port Washington, Wisconsin that builds lawn and garden equipment under various brands. The company was originally founded by William J. Niederkorn in 1922, and started building walk behind two wheeled tractors in 1939. Between 1941 and 1945, due to World War II, Simplicity Manufacturing temporarily halted production of lawn and garden products, and manufactured electric fence controllers and external surface grinders to satisfy the War Production Board. Simplicity first built a riding tractor in 1959 which was the model 700 Wonderboy. Allis-Chalmers purchased the company in 1965, and Simplicity's management bought it back in 1983. Simplicity Manufacturing celebrated its 75th anniversary in 1997 with a special 75th anniversary tractor model. The tractor featured a special blue paint scheme with chrome Harley-Davidson lights and muffler.
Sometime after AGCO Corporation purchased Deutz-Allis from Deutz-Fahr and KHD, Simplicity took over building and selling the Deutz-Allis lawn equipment. The name was later changed to Agco-Allis, and then to AGCO to reflect the changes within the AGCO Corporation.
After AGCO purchased Massey Ferguson, Simplicity began building and selling the Massey Ferguson lawn equipment. Simplicity bought the Snapper company in 2002, although (ironically), Snapper built Massey Ferguson lawn tractors many years before.
Over the years, Simplicity has also built lawn & garden tractors for J. C. Penney, Montgomery Ward, Viking (part of Stihl), Homelite Corporation and Rapid. Hinomoto/Toyosha built some of the larger compact tractors sold as Simplicity, Deutz-Allis and Allis-Chalmers.
