Correct deck belt is: 954-04318. What belt(s) have you purchased?
Okay, so let me look at the diagrams and see what is missing to get the belt to fit properly.
The spring that you are referring to goes towards the rear of the mower. trying to find where it hooks now
the engagement cable goes to the idler puller arm. when you push to engage, it pulls idler pulley. Here is the manual for the mower.
Every parts list and diagram I am seeing shows that, that is the correct belt. Which leads me to believe that the idler pulley is not being pulled correctly. or something is not where it is supposed to be. Hard not being able to see yours, and also the diagrams are no good for this mower online
Looks as though the spring 732-04967 connects to the upper floating idler bracket and then should go towards rear of mower and hook to either the belt cover, deck, or a bolt that is mounted to deck. Look around and see if you see an area that shows signs of wear of a spring moving .
I have included a crayon diagram. I believe the spring I going to attach to one of the areas shown by red line, or somewhere in the area of the lines.
