My deck belt is worn or needs adjusted (I think). So I adjusted the PTO Linkage as tight as it would go and the bolt on the bellcrank and the indicator arm are still about an inch from being in alignment. Is the belt trash or is there something else that needs adjusting?? This is the only info I can find on the matter= http://www.exmark.com/pdfs/103-2925.pdf on page 39. I really need help on this one. I bought the mower used and this is my first TThp so I dont know what has been adjusted where. Please dont make me take this to the dealer!!
