I don''t have any experience in deck leveling on my Hopper. I bought mine used, and I ordered factory operators manual for both my mower and for it's power tilt deck. I'd advise you to call nearest dealer and get the operator's manual for your mower, and for deck if it has separate operator manual. And you can call (620) 345-8021 which is the factory to talk to a tech rep. 1st thing they will ask you is where your nearest dealers are, and who they are. So try to run this problem thru your nearest dealer first. I do know that on my powerfold 72" deck, there is a procedure in the mowing deck manual that talks about that. Likely different for your mower. Be sure to write down the deck model number stamped on the tag so as to have it handy when you call dealer or factory. Best to have mower tag model # too.
