Z225 Deck out of wack

Hello all,

As of recent the deck on my zero turn has come un level, I've tried leveling it myself with the john deere deck leveling tool. The back of the deck I can get level to any setting I'd like. but the

front of the deck I am having great trouble with. I can get the right blade to be 1/4 of an inch lower front to back but the left blade the best I could get was a 1/2 inch. Now this is blowing

my mind here. I thought tire pressure was low somewhere so I filled them all to spec and that did't help. My blades are also new as of this year and are sharp. The only thing I could think of is

that I have one original spindle and one new designed spindle with the grease port up top as well as the larger blade connection. But last year I was level. Blowing my mind here, I'm out of

ideas so any you guys have would be great. As a side note first pass is uneven but if I do a second pass it becomes even. :banghead:

Thanks
