I have a 2003 Lazer EPS 60" and have a question about the mule drive belt. The belt my owners manual calls for is 103-3097. I went to pick one up from a dealer in Orlando today and they said it had been superceded by another part number, 103-4014. So that is the belt I came home with. Now, curiosity sometimes causes me more trouble than it's worth, but on the way home, I could not help but wonder if I got the right belt. It would be just the luck to drive an hour to get it and an hour back and get the wrong thing. It's happened before. So when I got home I went to look up my part number on Exmark's website and it shows "for 103-3097 use 103-4092 (kit)." Kit???? My serial # is 393,xxx. It also shows, in the exploded view parts list, use 103-4014 for 399,000 -up. Use 103-4092 for SN 370,000 398,999. So, I have the wrong belt, don't I?
