OF

AGRICULTURAL ENGINEERING

THE MASSEY-HARRIS NO. 20 WAS THE FIRST COMMERCIALLY-SUCCESSFUL SELF-PROPELLED COMBINE USED TO HARVEST SMALL GRAINS UNDER A WIDE VARIETY OF CONDITIONS, WORLD-WIDE. ENGINEERED BY THOMAS CARROLL, CHIEF ENGINEER, AIDED BY ROBERT ASHTON AND ALBERT LUKE, PRINCIPAL ASSISTANTS, IT WAS FIRST MARKETED IN 1938 BY THE MASSEY-HARRIS COMPANY. THIS COMBINE OPENED A NEW ERA IN FARM MECHANIZATION AND REVOLUTIONIZED THE GRAIN HARVESTING PROCESS. FORTY-FOUR YEARS LATER, THIS SAME HARVESTING PRINCIPLE CONTINUES TO BE USED THROUGHOUT THE WORLD.
