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 riding garden tractors in 1939. Allis-Chalmers purchased the company in 1965, and Simplicity's management bought it back in 1983. Simplicity manufactures lawn and garden tractors. It also offers zero turn mowers, riding mowers, walk-behind mowers, and snowthrowers.
A major step in the company's evolution took place in 1955 when Simplicity began to offer a snow throwing attachment to its walker. This advance led to the 1961 launch of a single purpose, walk-behind, 23-inch rotary snowthrower using a 3.5 horsepower motor. The Snow-Away retailed for $285.
