The drill in the middle picture is a John Deere. I know. I have one.
This one appears to have a fertilizer (?) attachment piggy-backed to the seed bin........that's the odd looking rear box attached to the back of the main bin. Never seen that before as that was generally a separate implement towed behind the drill, but.
Of your options, buy this one. Why? I'm not a JD fan at all, BUT, JD built some of the best working grain drills known to man and this is one of them. Extraordinarily simple and robust yet effective. Parts are available as well. As bad as it looks, it is not very far from operational condition assuming all of the internals are there and rust has not locked them up. Before buying crack open the seed bin door and check to see if the agitator and gears are there. If they are, good. A little grease, used motor oil, and some activity will have them working a wonder. The bent, mangled portion attached to a board that you see is the landing that was for manually loading the bin. Fix it.......remove it........re-man it. Little difference to operation depending upon how you want use it.
Besides in the pics of the other one it is missing some parts.....chains to be exact.....that you'll probably have to fabricate yourself. And I can't ID it. Don't know what it is.
Buy the one in the middle pic. You have my TBN ID for help. PM me. Of the bunch, it's the best you can get. Guaranteed.....
