AGCO was formed in 1990 to purchased the Deutz-Allis and Gleaner brands from KHD (Deutz-Fahr) in Germany. (DF is now owned by Same Deutz-Fahr, an Italian company).
AGCO later bought White (Oliver, Cockshutt, Minneapolis-Moline), White-New Idea (New Idea and White equipment), Hesston (hay tools, not the tractor portion), Massey Ferguson, McConnell Tractors (built the MF 4WD originally, and then the AGCOStar), Fendt, Valtra (Valmet, Valtra Valmet, Volvo, BM Volvo), Spra-Coupe, Tye (Glencoe, Farmhand), Deutz Argentina (Deutz-Allis in Argentina), Willmar, Caterpillar's Ag division (Challenger) and Ag-Chem. Tractors are sold under the Deutz-Allis (Argentina only), AGCOStar (S.America), AGCO, Massey Ferguson, Challenger, Fendt and Valtra brands. They previously have distributed Landini, Same, Deutz-Fahr and still distribute some Iseki tractors (Australia).
They own 24% of Tafe of India. (Tafe just bought the Eicher tractor company of India)
Tractors are built by AGCO in USA, France, Brazil and Finland. They are licensed built in several other countries. AGCO has or does buy and relabel or license tractors built by Iseki, Same Deutz Fahr, ARGO (Landini/McCormick), Carraro, Tafe, Ursus, Uzel, Millat, Farmwell, IMT, MTF, ITMCO and VenIran. (probably missing some).
Combines are built in AGCO factories in USA, Brazil and Denmark, and by Same Deutz Fahr (Laverda) in Italy.
How's that for a "brief" run-down?
