That could be the problem. Manufacturers tend to use unique width and length belts. The belt you have may just be too loose. I've seen this first hand many times, the shorter the belt the more likely it will be to cause trouble if a "premium" belt or generic is used. Generics are usually exactly as the originals they replace though. The word "premium" is misleading, when describing belts it means cheap. :tango_face_wink:In regards to the right width on the belt, I'm not sure where the old owner got the belt he said he put on it last year, but I'm wondering if it wasn't an actual John Deere part. The one I picked up from the dealer today was gray in color... almost white, and looked like it was made out of a different compound than the belt that's on it now, which is straight black.
