Tractors 2015 Square 12x12 Wall Calendar
Steam-powered tractors have been around since the mid-1800s, but it was the internal combustion models of the early 20th century that truly revolutionized the world of agriculture. Weary draft animals and overworked farmers all of a sudden got an enormous helping hand in their never-ending struggle to plow large spreads of land and pull heavy loads from field to field. When the pneumatic tire was finally introduced to heavy machinery, the tractor became even more versatile and further secured its place on the farm. Celebrate the beauty in both function and form of tractors in this unique wall calendar.
