Not a kioti owner either, but the first thing you need to do is call your dealer. If you have a good relationship with your dealer, they may just send you the parts.
Only warranty claim I had on my Kubota was the tach cable twisted off at 0.3 hrs. Being a mechanic, it was no big deal to change and would save the dealer a trip out with a tech. They gladly just mailed me a new cable at my request. Although they would have also gladly did it themselves, it was not a big deal for me to do it when convenient for me
