Hey FWJ, that looks to be a 6ft bush-hog squealer on the back of that awsome looking MF. I had a 5 ftr for many years. It was ok on my 8n but got busted up pretty bad when I used it at higher ground speed on a Ford 2000 that had a good bit more pto hp. I had to weld angle almost all the way around the top of the shell and beef up the frame. It always made a real neat cut and I never had anything but structural problems that could be easily repaired with welder and some scrap steel. Unfortunately, when I sold the 2000 (which was pretty well spent) , the guy that bought it really wanted the beefed up squealer and I had to let it go or would probably still be stuck with that wore out tractor. I replaced it with a Rhino 6 ftr which is structurely sound but does not cut nearly as neat as that old bush hog. Do you have similar experiences with Rhino, and how has that squealer held up for you? The one I had was an early eighties model.
