I have a craftsman riding mower with 42 in deck and it cuts uneven I have replaced the deck , mandrills, blades ajustment screws basically everything that goes with the deck and have tried every ajustment possibly know to try and get it to cut evenly also I have all four leveling wheels everything, and I cannot get it to cut even it is the left side that cuts lower the side with the bag cuts higher no amount of ajustment the nuts above the deck help in fact there ajustment stripped again anyone have any suggestions? Please Help!

Double check recommended tire air pressue on all 4 tires, they must all be the same. The wheels do not regulate cutting depth, they prevent scalping. Are you saying that when you change the deck height adjustments it makes no change in the level of the cut at all, can you make it worse by adjusting the wrong way?
