Used John deere 42 inch accel deep mower deck shell from an x370 and fits others, please check with dealer on other fitment. The spindles and blades were slightly out of alignment boiling down to it being the deck that needs some massaging to get the spindles to ride true again.
I don't the time to straighten it out but it can be done. Even the dealers have a way. Deck only has 180 hours on it. Straighten it out and you got yourself a good solid deck. Or run it like it is, it will just leave a little strip of uncut grass hear and there. This shell is $580 new.
