Attached is a picture of my C-200 two bottom disk plow I just got painted. I don't think it is very common in the Midwest, but I purchased it about ten years ago when I lived in Texas, which I think it is more common. Probably will never plow with it again but I did replace the bearings in the furrow wheel. They are the same bearings as the front axle for a Farmall Cub. The plow has seen a lot of use and scrapers (not visible in the picture) on the disks are pretty worn.
It has the smaller prongs to fit the fast hitch on my Super C.
