I have just bought a L260 and am planning a full service before i put it to work. I have everything i need except for a thermostat. Kubota told me today “good luck finding one of those”. The oem part number 10231-73010 does not seem to cross reference to any other thermostat. Does anyone know of a good replacement to try. Ive already tried oreilly’s, advanced auto, and NAPA.
