1920's TRACTOR First Day of Issue: February 6, 1987 First Issue Location: Sarasota, Florida The Tractor of the 1920's evolved from the internal combustion engine Traction-Motor machines of the 1890's. These machines made the cultivation and har- vesting of large tracts of land possible. No longer was it necessary to raise farm work animals such as large draught horses or oxen. A single man and his machine could now increase both a farm's workable acreage and crop yield with an undreamed-of efficiency. Yet until the 1920's, the Tractor was primarily a mobile source of power for operating equipment such as threshers. However, the introduction of the "power takeoff;" which allowed rotary power from the engine to be transmitted through a flexible shaft to drive hay balers, combines or mowers; revolutionized the Tractor's role in farm produc- tion. One farmer could now produce enough to feed twenty people. Today's modern Tractors are divided into two main types; Wheeled Tractors, still commonly found on farms across the nation, and Caterpillar Tractors which move on treads.
