About Massey-Harris
Massey-Harris was formed in 1891 by combining major Canadian machinery businesses. Its 1953 merger with Harry Ferguson’s company created the predecessor of the Massey Ferguson identity.
- Beginning
- 1891 merger
- Founder / origin
- Massey Manufacturing and A. Harris, Son and Company
- Known for
- Harvesting machinery and agricultural tractors
- Sale / later history
- Merged with Ferguson in 1953
History and legacy
The Massey family’s equipment roots reach back to Daniel Massey’s 1847 workshop, while the Harris business had its own founders and earlier history. The merger and subsequent name changes should be kept separate from AGCO’s much later ownership.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
