I had the same problem dealer found out it was a sencitivety switch on the hydrastat pedal they put a spacer somewhere to correct the problem it’s working for the last three yearsI bought a new Kioti NX4510 hst last fall. I now have 67 hours on it and experiencing a re-occurring problem with the calibration light coming on and the tractor won't move at all until the light goes out. This has been occurring since since I bought it and the dealer said it was a loose connection at the calibration button. I've checked the connection, cleaned it and still no help. I've changed the transmission oil, hst filter and transmission filter at the 50 hr service as per the manual, and I believe it's getting worse. Anyone had any issues like this? Dealer has not been much help.
