Big Bud 525/50 pulling a 21 bottom plow. This was taken at the Alvordton, OH Plow Day on 8-8-15.
To try and answer some of the questions in the comments, a plow day is where people bring antique tractors and plows and plow a field for fun and nostalgia. (Click here to see the antiques youtu.be/iwVN30OtJho ) This tractor and plow were there for people to look at and see in action. It's not really used for actual production as plows are mostly obsolete at least in this part of the country. I've been told this plow and tractor originally came from North Dakota where it would be more practical.
The video was filmed with a DJI Phantom 3 Advanced.
