SOURCE: how to adjust the mower deck on my murray rider,

Park the tractor on a firm, level surface. . .
At the lower end of the lift/lower travel slot, there should be a plastic cover which you pop up so that your blade lift handle goes all the way down (it should say something about blade level on there somewhere. . . . .
After you have the handle in this position, look at the front lift arms of the mower deck and find the 2 large wing nuts, one on each side. . . . .
Loosen these while the deck is down and then retighten them Your deck is now level and will lift to its highest recommended position when you raise the lever

SOURCE: how to replace deck belt on lt 1000 craftsman

there are several belt guards that you will need to loosen then the belt will slip right on. having someone hold the clutch will make it easier, and the belt diagram should be on the deck. If not, these are common mowers, so a search for this or a friends/neighbors mower may hold the answer. Be sure to re tighten all guards or your belt will pop off and wear out very fast against these metal parts

SOURCE: 2010 Craftsman Lt 2000 deck height adjustment?

just bought a new craftsman riding mower. model lt1500. 17.5 hp with 42 inch deck. first time using I had the deck hight handle set on 6 the highest setting and still cuts grass to short, matter of fact it scalped the grass. anyway to set the deck higher. Its only 3 days old and still under warranty but the sears store is 20 miles away and I rented a trailer to go pick it up and hate to go rent another trailer to bring it back if its just a simple adjustment.
