I thought I would share my "new" plow, it originally started life as a two row but I converted it to a single. It had been sitting under a tree for at least 40 years it had a 12 inch oak tree growing right in the center of it. Everything is worn but it still works to turn over my garden and plow in a few ditches. It's a Ferguson 12 AO 40, the tags hard to read but I believe that's what it says.
