I've noticed decks have two types of front mounts. The 'old' way is a substantial wide mount parallel to the front frame crossmember at the axle (the mount being parallel, not the deck) with two connection points to the front of the tractor. Some are adjustable and some are not.
The fixed mounts have a ~5/8" rod 6-12" long connecting to two points on the frame under the front axle pivot point. The other adjusts to two points of the frame under the pivot point, or adjusts where the mount connects to the deck.
When setting front deck height on adjustables, the nuts on each side should be turned the same amount. If not, the deck can rotate or pivot to the left or right with respect to the front axle pivot point.
If the front mount hangers of the fixed type are bent, or the other type maladjusted or if one side of the front of the deck is bent the deck can rotate around a point between the spindles and the front mount. If it rotates in the wrong direction (a line between the spindles becomes more parallel to the front axle), the blade overlap will be lost. With some rear hangers, it will pivot instead of rotate.
The 'new' type of mount has a single front connection point on the centerline of the frame. My ZTR has this type. There is usually less of a problem with deck rotation on this type of mount because of the rear hangers used.
Rear hangers on the fixed and adjustable mounts can contribute to rotation if they are connected to the wrong side of the hanger mounts of the deck. If both are connected to the left side instead of both to the outside or something like that.
What I'm trying to say, I guess, is check deck rotation with respect to the frame. The deck should be hung with (usually) the left spindle closer to the front axle than the right. I have seen no specs or measurements of this, Craftsman, but if you post your model no. maybe someone with the same machine will measure theirs so you can compare. A simple measurement from the front axle pivot point to the right and left spindle will reveal lots. The bigger the difference between right and left the more the blades overlap.
Sometimes deck rotation is changed slightly at the factory in order to fit larger tires on the tractor. Deck rotation vs. tire size is apparent at the left front and right rear tires. Somewhat less than bright eyed and bushy tailed engineer, I guess.
