I have an older Murray/MTD (???) and we recently had problems with deck hanging system. DH went to the Murray site printed out things he needed and also replaced the belt, ball bearing in the pulleys etc. Now the deck hangs funky, too low in the front when its engaged. It only wants to turn on the lowest setting but as soon as you try to cut the grass it turns too slow or stops turning altogether. Weird thing is when you pull the deck up in the disengaged postion, it looks fine.
