That's strange ,my BIL and I both have the 60in with just under 200hrs each and the only thing we have done is replace the belt on his (not the machines fault it was cut) blades oil and filters.Terrible mower but good warranty. I have had over 30 parts replaced under warranty in 3 years on my Raptor SD. Only the engine Kawasaki is original. Only 139 hours. Even replaced the entire deck last year as it was rusted out. Dealer said hustler sent out a lot of rusted decks and just painted over them. My next mower will be green.
