With roots that are firmly established in the North American farm equipment industry, AGCO Corporation has a heritage that reaches as far back as the mid-1800s through many of its brands.

Its direct lineage is from the Allis-Chalmers brand name. AGCO got its start in 1990 with the purchase of Deutz Allis Corporation from German-based Kloeckner-Humboldt-Deutz AG. KHD, in turn, had purchased the Allis-Chalmers agricultural equipment business five years earlier. Since that time, AGCO, the industry consolidators, has become a worldwide farm machinery company through market growth and strategic acquisitions. Today, with sales of approximately $3 billion.   AGCO brand products are sold in more than 140 countries by over 8,000 dealerships and markets 22 brands with over a millennium of combined heritage. 

 4wd tractors have a 76 year heritage in the AGCO Corporation.  AGCO traces its tractor roots back to the Hart-Parr Oil-Pull tractors.  Hart-Parr became part of the Oliver company in the 1920's. Also in the 1920's  Massey-Harris purchased Wallis tractors makers of the first 4wd.  In the 1950's Massey-Harris joined with Henry Ferguson to form Massey-Ferguson.  In the 1960's Oliver became part of the White Motor Company which later acquired Minneapolis-Moline and Cockshutt.  Oliver Green, Minneapolis-Moline Yellow and Cockshutt Red were merged in 1975 under White Silver.  During the 1980's White joined forces with the well known implement company New Idea under Allied-Products.  In 1986 the long time orange brand Allis-Chalmers was purchased by Deutz-Fhar and became Deutz-Allis.  In 1990 Deutz-Allis was purchased by the newly formed Allis-Gleaner Company (AGCO).  AGCO began selling AGCO-Allis tractors and Gleaner Combines.  In 1993 AGCO purchased the White-New Idea brand.  In 1994 AGCO acquired the Massey-Ferguson brand along with McConnel-Marc 4wds.  In 2002 AGCO purchased the Caterpillar Challenger tracked tractor line.  Today AGCO offers the industries largest horse power tractors under the Challenger name.

	In 2002, AGCO acquired Caterpillar Inc.'s agricultural equipment business, primarily the design, assembly and marketing of their Challenger track tractors.  Since 1987, when Caterpillar introduced the world’s first farm tractor equipped with rubber tracks, the Challenger name has stood for awesome power, cutting-edge technology and amazing versatility. Today, Caterpillar dealers continue their dedication to the farming community with a full line of agricultural products, many of which are specifically designed and built by AGCO to carry the Challenger logo.  Challengers largest tractor the MT865 lead the industry at 500 hp in 2002.  In 2005 Challenger increased its horse power lead with the new MT875B rated at 575hp.

AGCO-Star 4wds were produced from 1995-2002. The 360 hp 8360 and 425 hp 8425 AGCO-Star 4wds were available with both Cummins and Detroit-Diesel engines through 1998. From 1999-2002 only Cummins engines were available.  The Challenger MT800 tracked tractors took over high horse power in the AGCO line in 2002.  The AGCO-Star was sold in the White brands silver and the Massey-Ferguson brands red.

McConnell purchased and then resold the Marshall Tractor Company (formerly Leyland Tractor )  In 1988, McConnell acquired the rights to the Massey-Ferguson 4000 Series 4WD Tractors. With upgraded power and options, these tractors became the Massey-Ferguson 5000 Series.  In 1993 the 360 hp 900 and 425 hp 1000 McConnell - Marc 4WD Tractors replaced the MF name.
	In 1953 Massey-Harris and Harry Ferguson merged to form Massey-Harris-Ferguson Limited. Later this was changed to "Massey-Ferguson". In 1958 the company acquired F. Perkins Ltd of England who was the leading diesel engine producer at that time. This gave the MF company a ready source for diesel engines. In 1970 Massey-Ferguson entered the articulated 4wd market with the MF 1200 4wd.  MF introduced its big 4000 4wds in 1980 and remained in the 4wd market through 1992.  The last MF 4wd, the 5200  was the first 4wd in the 1990's to reach 425 hp.  Massey Ferguson 4wd History
