It is a single speed tractor and the clutches were pretty easy to change out. The original clutches were still in the tractor a brass or bronze colored and had no hot spots in the plates or wear. The floating ring that sets against the piston was broken so I had to replace it. I started not to change out the original clutches and plates but I did. The replacement ones from ford looked like transmission clutches and not at all like the original brass ones. If guessing, the original ones are probably better but not for sure.
