Hi Guys, I have a Craftsman DYT4000 (about 10 years old) and I have been having trouble with cut, leaving stripes in the yard. I found one of the shafts that hold the blades to be bent so I searched on line and found a deal on the mandrels and changed them both. after doing this I used the manual as a guide and I am trying to set the deck, I can get the right left within specs but cannot get the front back, the back is staying between 3/4 - 1 inch higher than the front. Also if I adjust so the blades are around 3 3/4 off the ground, I have the deck so high it is not floating anymore? Any suggestions (less taking it to the shop, haha) Thanks in advance.
