I appreciate the advice. However, I am not sure what would be wrong with the new belt, as the dimensions are the same. Is there any adjustment I can make that will allow this belt to work?Welcome.
I think most everyone on here will agree that OEM JD belts are the only way to go. You may find that it will correct the problem. If the old one didn't jump off the new one shouldn't if it is correct.
Also, this is my first time replacing this belt, so I may have overlooked something, but I have checked the big things like proper routing.
This is what I'm working with (not my pic, but same type):
