1920's Tractor
Additional Details:
| No.87-5. The Tractor of the 1920's evolved from the internal combustion engine Tractor-Motor machines of the 1890's. These machines made the cultivation and harvesting of large tracts of land possible. No longer was it necessary to raise farm work animals such as 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 production. 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 |
