cut ,or broke another belt today. tightened everything and while she got some hrs on her . i dont see what can be getting these belts.when it broke ,the blade belt also came loose . i felt a little play in the blade tension pulley ,but really very little. its like theres a certain situation coming up once in a while that is causing this ,but i cant figure what it is. also it does look a little like its been cut by a pully or something. is there any chance exmark has changed belt suppliers. now that would explain it. also exmark needs to know ,if u guys are experiencing more broken belts.thanks for your attention.
