if i am thinking of the right model you may be able to get away with first taking off the blade, then to remove the deck should be a number of bolts under the chassis and on top of the deck where it meets the frame... you can get your parts here if your having trouble finding them

If idler is in tact and spring attached, it is likely that the belt isn't routed properly. If you try to route the rear-most portion of the belt around the idler, it will be loose. You must route the front-most portion of the belt around the center blade pully and then around the idler. Just Google "MTD 46 inch deck diagram" and you will go to a Parts Tree site with the proper diagram showing routing.

A FEW THINGS TO LOOK AT ARE ,1THE PULLY SHIELDSMAKE SURE THEY AREN'T BENT TO CLOSE TO THE PULLEY'S.2 THE PULLEY BEARING'S MAY BE WORE OUT AND TO BREAK .3LOOK UNDER THE DECK TO MAKE SURE YOU DIDN'T GET SOMETHING TRAPED IN THE CUTTING DECK.HOPE THIS HELPED.

I have the exact same model MTD tractor with same problem. It began when the bolt that extends through the idler arm assembly broke and subsequently damaged the pulley. Upon examination of the broken bolt, I found that the threaded end that extends below the deck is significantly smaller that the rest of the bolt. I got a larger bolt with the same size threads, bored out the hole through the deck and it made the whole idler assembly much stronger. the deck still has some vibration and some unusual belt harmonics, but it appears to be working. Compared to most other tractors of this size, this deck is very complicated.
