X300 shredding belts

[akroeze]

I have an x300 with about 75hrs on it. It has now taken to shredding its deck belts. This is the second one that has been shredded and it only has 10 hours on it. When I went to pick up the shredded belt from the ground it was hot to touch. All of the pulleys were noted to be VERY hot to touch (couldn't keep your hand on them for sure) but they all spin freely. Is this amount of heat normal? What can I do to solve this problem? $75 belt/10 hours is quite costly.

Could the belt be rubbing against the deck leveling bolt?

Check belts, alignment, and the spindle bearings.

With new belt on and alignment verified good, then run a short time and feel for anything getting warm (before it gets HOT and starts to chafe).
