AGCO Corporation was formed in 1990 in Duluth, Georgia, when the North American tractor business of Deutz-Allis was reorganized under new ownership. Deutz-Allis itself had been created in 1985 from the agricultural operations of Allis-Chalmers, so AGCO's roots reach back through decades of American farm-machinery history. The company has since expanded through acquisitions into one of the world's largest manufacturers of tractors, combines, hay tools and application equipment.

AGCO is known for the strength of its brand portfolio, which has come to include Massey Ferguson, Fendt, Valtra and Challenger alongside the AGCO Allis name, each serving a different part of the world market. The group also owns AGCO Power, its dedicated engine-building operation with roots in the Finnish SisuDiesel company, which supplies diesel engines for AGCO tractors and other applications. Its engineering focuses on efficient diesel power, high-capacity hydraulics, precision-farming electronics and operator comfort.

AGCO workshop manuals give complete factory guidance for the equipment on this page: diesel engines and their fuel, cooling and emission systems, transmissions and rear axles, hydraulics and three-point linkage, PTO systems, steering, brakes, cab climate systems and the electronics that control modern machines, with full wiring diagrams. They also include torque specifications, diagnostic routines, test procedures and the scheduled maintenance intervals recommended for each model.

These manuals suit farm owners who service their own machinery, independent agricultural repair shops, dealer technicians and equipment restorers who need accurate specifications for older AGCO, AGCO-Allis and Deutz-Allis machines.
