QuoteHow much did tractors increase productivity? "The U.S. Department of Agriculture reports that it took 40-50 labor hours to produce 100 bushels of wheat on five acres with a gang plow, seeder, harrow, binder, thresher, wagons, and horses in the 1890s. By 1930, it took 15-20 labor hours to produce 100 bushels of wheat on 5 acres with a three-bottom gang plow, tractor, 10-foot tandem disk, harrow, 12-foot combine, and trucks." http://www.livinghistoryfarm.org/farminginthe20s/machines_01.htm
