I've replaced the clutch at least three times in the past year. For some reason it keeps wearing out faster and faster. I've replaced the transmission, brake, pump, etc. It's pretty much a brand new machine except the clutch keeps wearing out. I already know putting heavy loads in it would do it, that's not the main issue. After I replace it, it works great but after a few months not so much. Any suggestions on why it keeps breaking?

thanks
