AGCO was born when the US management of the Deutz-Allis corporation bought out the North American side of the company and renamed it AGCO (Allis-Gleaner Company). The AGCO line of lawn equipment was manufactured by Simplicity (now Briggs & Stratton), using the AGCO name under license. This line replaced Simplicity's previous AGCO-Allis line of lawn equipment. AGCO began phasing out the AGCO name in 2009. This lead Briggs to phase out the AGCO name and revive the Allis Chalmers name for lawn equipment.
