The company was founded by William J. Niederkorn in 1922, and started building walk-behind two-wheeled tractors in 1939.
The company rapidly expanded its product line in the sixties to meet the demands of the population shift to American suburbs.
The tractor featured a special blue paint scheme with chrome Harley-Davidson lights and muffler.
Over the years, Simplicity has also built lawn and 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.
