The implement in the pic would most likely have ended up in a scrap yard had I not purchased it.
Really had hoped to also get some mounted cultivators and other accessories that were made to fit a model 70 and some for a 720 from the same seller. Someone else decided that hauling them to a scrap yard was more important.
Oh well, you win some and you lose some.
So far, I haven't determined with a 100% certainty if this is for sure an F311 bedder, but it is very similar.
For $100, I figured it was money well spent. You can't tell by looking at the pic that it's 12 feet in length from one end to the other. Hopefully some original hub caps/covers can be purchased elsewhere.
