Going through belts

[walkingit12]

I attached a link of my mower deck belt, does this seem too loose? Any suggestions? This is my 3rd belt and I think it’s rubbing somewhere causing them to snap. This is a Snapper spx 48” 2691346-01. The manuals I had found aren’t much help but the deck diagram matches and everything is where it is supposed to be.

Looks like a lot of slap in the belt check for bent pulley or shaft.
