When I got my Suburban 10, it had a 3 point hitch, minus the center link of course. (Just what happens to all the center links? ) It is the early style, 2 bolt one. 917.251781
I found a center link, the guy said it wouldn't work with his hitch so I bought it for a good price. $20. It is the kind that you always see on ebay for outragious prices, with the clevis ends. Well, it didn't work with my hitch either, you couldn't raise the handle all the way.
Today, I made a trade for the 4 bolt piece with the handle and switched them out. Now I have a handle that if not careful, it lays back on the tire. I would like to find the origional type center link, but in the meanwhile, I do have a hitch that I can use but I need to fabricate a piece to keep the handle off the tire if it falls back. I remember seeing a thread showing the modification here somewhere but have searched and searched and can't find the thread. Can anyone point me to that thread?
