How did the tractor contribute to the change from agriculture to industrial?

Answer 1

With the domestication of the horse, mule and the donkey agriculture grew well beyond the acreage tilled by man using his brawn. With the horse and mule man was able to cultivate many more acres. When the power source of the tractor came into being all the implements drawn by the horse for tilling and cultivating the soil were increased in size eliminating the need for numerous farm hands. As the industrialization of the nation began the excess farm labor gravitated to the industrial sites.
