last year My 54D mower deck wasn't cutting level. I leveded it and re-leveled it. The right side blade cuts lower than the other 2. My dealer even took it back to their shop and releveled it. It still didn't fix the problem.
I complained early spring of this year, they took the mower deck back in their shop and "Pressed it". It helped a little bit but now it's right back where it was. The lawn doesn't look that great after mowing either.
The right side bearing assembly was also replaced.
I checked w/my JD dealer for replacement, $1900 with new gear box and arm $1260 for the deck with out gear box and arms.
Has anyone ran into this same situation?
