Engineering Products Company of Waukesha, Wisconsin produced a variety of garden tractors from 1946 until the early 1990s. Engineering Products sold their tractors under the Economy, Power King, and Jim Dandy names. The tractors changed little during the first thirty years of production. During the 1970s, the Economy and Jim Dandy names were dropped and the company began using the Power King name for their entire tractor line. Engineering Products - Power King went through several ownership changes in the late 1980s and early 1990s, eventually ending with Yazoo, a manufacturer of commercial mowing equipment. Production of new Power King tractors ended.
