Hours on clock does not seem to be an issue. Mine started at 10 hours and has been there constantly; now at 150+. End of last week, my dealer says Kioti has sent reps by some dealers to explain how the newly installed computer system has/is hampering parts orders, etc. AND he said that Kioti is well aware of the problem of the squeal in some tractors and is waiting for word from S. Korea, and /or the transmission guys in Scandinavia.
Believe me, no one will have to listen hard to hear the noise if it crops up. You'll know it right away. It will sound like you're dragging your emergency brake on your car, except louder.
CM out.
