We bought a new CK3510 with a loader attachment, in Dec.2015, 4 yrs 3mos. 150 hrs, and the dealer calls that the clutch is shot, no grinding, No smell. Kioti refuses any assistance saying we must have abused the tractor. We sent 3 emails , 2 phone calls no response. There's no way this tractor was abused, 150 hrs is barely over breaking it in. They claim they have had no problems or complaints with the clutch, I found several going back as far as 2007. DON'T BUY KIOTI, they will not stand behind their trctors.
