i agree with all of the above, also keep in mind that ECU are normally set up to be sinking inputs ie the power goes to the sensor then returns to the ecu so that shorting the sensor has no permanent effect on the ECU or sensor.
shorting the sensor will stop proper operation while the short exists but replacing the ECU or Sensor is pointless other that a poor man's trouble shooting process. which is why the techs recommending replacing the ECU is a warning sign that they do no know what they are doing.
a qualified tech knows how to test any and all sensors/ the ECU on the tractor, if they are doing the black box replacement game they are guessing.
And there it is! Thank you DaBear3428. We are all dealing with a society that doesn’t mind taking your money but they don’t want to learn anything or fix anything. Another generation lost.
