No deal at all. 2500 hrs on the concaveIJ Now you need bars and concave probably all unloader augers and most likely feeder chain, also just about everything else that turns. VariableIJ I am surprised anyone would like to go back to a clutch. You will probably have over 10000 bucks in parts with labor to be supplied. Sorry, you asked. BTW, I have an 84 6620 with hydro and I have kept it in absolute fixed condition and I know it is worth 8 to 10 grand and only 2800 hrs. in SW iowa. Good luck, take it to the best Deere combine tech to completely inspect it because you will not see all it needs.
