Now just why are those so hard to find? seems like there must have been one for every 3 point hitch they sold. Ha!
Actually, I needed one and found one last year. It is the one with the clevis ends. When I hooked it up to my 2 bolt, 3 point hitch, It hit so it couldn't lift the implement. So I ground part of it away and tried it again. Still didn't work. I needed the kind that has an L bend on each end. I ended up using something that wasn't adjustable but has got me by.
Here is a picture of the one that I can't use. Does anyone have an old style one that they may be willing to trade?
