Massey-Harris

Canada • 36 Models

Massey-Harris was a pioneering Canadian agricultural machinery manufacturer that emerged from the 1891 merger between the Massey Manufacturing Company and A. Harris, Son & Co., two of Canada's most prominent farm equipment producers. The company quickly established itself as an industry leader, achieving a significant breakthrough with the introduction of the first commercially successful self-propelled combine harvester, the Massey-Harris No. 20, in 1941. This innovation revolutionized harvesting practices worldwide. In 1953, Massey-Harris merged with the Ferguson Company, founded by tractor innovator Harry Ferguson, who had previously worked with Ford. The new entity, Massey Ferguson, became a global powerhouse in the agricultural machinery sector. Over the decades, Massey Ferguson expanded its international footprint, establishing manufacturing facilities and distribution networks across Europe, Asia, and the Americas. The brand became synonymous with reliable and innovative farm equipment, particularly in the tractor and combine harvester segments. In 1994, Massey Ferguson was acquired by AGCO Corporation, a leading global agricultural equipment manufacturer. Under AGCO's ownership, the Massey Ferguson brand continues to thrive, leveraging its rich heritage while integrating modern technologies into its product lines. Today, Massey Ferguson is recognized for its diverse range of agricultural machinery, including tractors, combine harvesters, balers, and hay tools, maintaining its reputation for quality and innovation.
