Massey-Harris Tractors
Massey-Harris was formed with the merger of the Massey and Harris companies, both major manufacturers of harvesting machinery in Canada. Massey-Harris merged with Ferguson, after Harry Ferguson had split from Ford, to form Massey Ferguson. AGCO purchased Massey-Ferguson in 1994 and continues to use the name.
