Ok, here's the thing, I've been running doubles on my 48" Scag Tiger Cub and it works beautifully! Except for the deck belt keeps breaking. That belt is about $60 and this is the second belt that's broken in a month (the other was at the beginning of June). Do any of you Scag owners run doubles? Have you had the same problem? I've noticed that whenever I get into thick grass, the trouble seems to hit. I know now what the sound of a belt that's getting ready to pop is. The dealer that I got it from says that it's because I'm running doubles. He says that the clutch on this machine was designed to be an instantaneous device with no slipping and the load that I've placed on it is just too much. Could this be true? Seems to me that there could be something done, I mean Walker and Dixie Chopper advocate using doubles. It's not like we're the first group that's ever tried it. Your input is greatly appreciated.
