Mine failed at 3 years, ~321 hours. Kioti paid for it, but I had to cover transportation costs for my far-away dealer. Certainly fair for the dealer to charge this. But, even at that it burns me that I had to spend $150+ to get it fixed. It's money I shouldn't have to lay out, and this isn't the first time.
I think all these "little things" that fail on our Kioti's points squarely at why Kioti isn't quite up to snuff with the botas and deeres. They are trying, but still seem to find ways to use inferior parts from time to time.
Hope you guys get yours fixed under warranty. I was told it depended on what was determined to be the cause of the failure after they examined the failed part. Good luck and stay after your dealers to get Kioti to step up.
