Vintage Tractors Scramble Squares
Tractors have revolutionized the way farming is done, enabling the production of vast amounts of food with increasingly less labor, feeding the world and helping to make possible the technological revolution of the 20th century.
Farming changed very little from its origins until about 1700, when an agriculture revolution occurred which led to a large increase in the production of crops, including crops from the "new world," such as corn and potatoes that produce very large yields. In the 1850s, the industrial revolution advanced farming with new mechanized farm implements, greatly increasing farm production rates. Most of these early implements were still powered by horse or oxen. The advent of steam power and later gas powered engines brought a vast new dimension to the production of crops. Early tractors utilized wide metal tires to disperse their weight in the soil. Front wheels often had ridges for helping to steer through the farm soil. Tractor traction problems resulted in engineers innovating a continuous belt with slats fitted to the front and back wheels that pulled the tractor through the soil. This traction technique has been made famous by Caterpillar company and is still popular for heavy earth moving equipment today.
