Lower the deck to its lowest setting with the engine not running and get someone to engage and disengage the mower deck. Watch the idler pulley (item 145 in the parts diagram) to see if it moves against the back of the belt to tighten it.

Watch the spring (item 148) to see if it moves the pulley away from the belt when the deck is disengaged.

I think you will find your problem here.
