Hello all, I could really use some help on this one. I have a 2005 Exmark Lazer 60 in that keeps throwing the PTO Mule belt under the pully its on that is on the deck. I am able to get it out but it damages the belt and they eventually break. I have went through 4 belts this year and I have had enough. I check the pully tensioner on the back right pully, the pully on the deck has no play in it. I am lost. I am just trying to prevent taking it in is all. Any help would be much appreciated. Thanks so much!
