Massey-Harris Co.

Massey-Harris was a prominent Canadian agricultural machinery company that evolved from a small 1847 blacksmith shop in Newcastle, Ontario. Growing into an international powerhouse, it revolutionized farming by introducing the first self-propelled combine and mass-produced four-wheel-drive tractor, before eventually merging into the globally recognized Massey Ferguson.
