My craftsman mower deck sags on the left, tires are ok. If I lift on the left side, the deck moves up and down but the right side is rigid, so seems to me that something in the left must be broke. The deck is lifted in the highest notch, but the left side is so low, it scalps the yard. Cant figure anything out from the parts breakdown. Thank you!!!

Not much info to work with, but until the solution appears, lower the anti-scalping wheel a notch or two. That's all I got.

I suggest you take the deck off the tractor, disassemble the Idler plate and check the welds on the deck. I had a similar problem with my DLT2000. https://www.mytractorforum.com/14-craftsman-sears-forum/931250-42-inch-lt-deck-problems.html See the picture in post #3. The deck size and some pictures would help.

My Craftsman manual offers these leveling procedures-

If you have the "adjuster dial" system, with the knob, you may find a broken part inside that allows the sag. Quite the job to obtain access, and good luck finding the part. You may need to contact someone with welding skills, depending.
The longer arms that the 'ball' nut supports may have wear in the 'socket' area that allows one side to sag more. You likely will find the cause by visual inspection and shaking or lifting.

Not sure if these will shiw in the order I uploaded them, but first two are of sagging left side of deck, the next to are of the deck at height it is supposed to be but I'm holding it up here, and last two are of proper right side. Hope this helps. Thanks!!!

Your manual has an instruction for deck adjustment as well: maybe there are parts broken or missing behind that hex-head screw. The deck looks like it can be pushed up/raised, using the instruction, in the shot you give.

Some tractors have stops that the deck pulls up against on the highest setting but sometimes the deck only contacts one stop even if it is properly leveled so you cannot go by that. However, if the deck is not properly leveled on a lower setting then you first need to do that by following the instructions in the manual.

My deck only ever makes contact with one of the stops. I actually ground down the right stop so that I could raise the deck higher but I could never raise it high enough for the left stop to make contact so that side will still move up and down while the right side is rigid. My deck is properly leveled so it cuts evenly.

In the second picture, it appears that the large hex-shaped nut(?) could be moved upwards on the bracket it appears to be attached to. I read the next post & instructions, which seem to indicate the screw in the middle of the hex can be loosened, and that follows what appearances indicate.
Loosen the screw, move the hex, tighten the screw.
