Mowing 54D Mower deck belt problems

[JohnCanny]

I have a 2320 with the 54d deck. The deck is two years old. I have already had to replace the belt on the deck, and by the looks of it I will have to replace it again soon. It is used to cut a lawn. There is nothing stuck under the ramps. I can not determine why I am chewing up belts. I was hoping someone might have some insight.
Thanks
