This is the only video I've found of a national plow day. This video dates back to 1918 and is part of the Ford Motor Company’s collection in the National al Archives. This public domain film starts off with a 20-40 case tractor, then you see through the dust a wide variety of early tractors. Ending with a couple Yuba tractors and a Fordson. This might have been the first competition where Henry Ford took his Fordson tractor. #antiquetractorlife #tractors #tractor #plowday #dieselpower #diesel #
