I picked this PTO extension up at a engine show a while back and just wondered what implements use or need these extensions? I don't have a need for it I just spotted it on the table of stuff the guy was selling. I knew what it was for right away because I've seen them on Ebay. The guy selling asked if I knew what it fit and I told him. He asked how much would it be worth and said I really don't know but it seems the ones on Ebay go for $30-$60... Even after saying that to him he asked if I'd give $20 for it. I told him I have no need for it but since it has the shield and a little bit of the original Dearborn sticker on it what the heck?? I was in the mood to buy I guess? LOL Anyway I just stuck it on a 8N of mine that is waiting for restoration. I guess you can say it's just a conversation piece at the moment..
