McConnell Tractors was formed in 1989 as part of McConnell, LTD. with the purchase of Massey-Ferguson's 4wd articulated tractor.

McConnell had been formed in 1961 by Ward McConnell.

His company purchased the Marshall Tractor Co. of England, (formerly Leyland), and sold it in 1985.^[4] Farmall tractors into High-Crop models.

The United Company, makers of in-plant corn equipment, was purchased in 1987.

In 1987, they began redistributing re-manufactured Kubotas.

MF's factory in Brantford, Ontario, Canada manufactured the Massey Ferguson 5200 tractor, and McConnell transferred manufacturing to their plant in Kinston, NC. ^[undefined] McConnell continued building the 5200 for Massey Ferguson, and then began selling it in yellow-livery under the McConnell-Marc name. ^[1]

In 1994, McConnell Tractors was purchased by AGCO, re-uniting the former 4WD tractor company of Massey-Ferguson with the rest of Massey-Ferguson. AGCO re-styled the tractor and renamed it as Agcostar.

After the sale of the tractor manufacturing division, McConnell later started a new division called McConnell-Marc Tractors which imported Jiangsu and Jinma tractor models from China under the McConnell-Marc brand.
