Massey-Harris tractors.

Massey-Harris was formed in 1891 when the Massey Manufacturing Company merged with A. Harris, Son and Company, and it was based in Toronto. Besides tractors such as the Pacemaker, Model 101 and 44, it is remembered for Tom Carroll's No. 20 self-propelled combine of 1938 and its lighter successor, the No. 21. A 1953 merger with Ferguson led to Massey Ferguson.
