  1. I have John Deere X475 and an amber light stays on. I have checked the Operators Manual and do not find this symbol. It looks like an open book. I see it here as I searched. It is "Malfuncton (alternative symbol) see Operators Manual"
    What is malfunction. What should we attend to.
    Thank you.

    • Hi Mary,

      The "Malfunction" light on your John Deere X475, represented by an open book symbol, is typically a general warning indicating that something is wrong with the tractor's operation. This could be due to several reasons, including issues with the engine, transmission, electrical system, or other subsystems.

      Given the general nature of this warning, it's challenging to specify exactly what's wrong without further information. However, here are a few steps you could take:

      Check Fluid Levels: Ensure that the oil, coolant, and hydraulic fluid levels are correct.
      Inspect Belts and Hoses: Look for any signs of wear, cracks, or leaks.
      Listen for Unusual Noises: Any strange sounds during operation could indicate a mechanical issue.
      Observe Performance: Pay attention to any changes in performance, like power loss or unusual engine behavior.
      Check for Error Codes: Some John Deere models can provide more specific diagnostic codes.
      If you're unable to identify the issue or if the light remains on after addressing any noticeable problems, it's best to take your tractor to a professional for a detailed diagnostic check. This will ensure that any potential issues are correctly identified and fixed, maintaining the health of your John Deere X475.

      Please remember to always refer to your specific model's manual or consult with a professional mechanic when in doubt. Safety is paramount when dealing with heavy machinery like tractors.

      I hope this helps! Let me know if you have any other questions.

  2. I have a 3032e tractor....just had routine oil change and other maintenance done. Noticed a white flashing light on the instrument panel, the shape of an hour glass. What does this mean? I bought the tractor used and don't have an owners manual.

    Reply
    • The white flashing hourglass light on your 3032e tractor's instrument panel is a service reminder light. It comes on to remind you that it is time to perform scheduled maintenance on your tractor, such as an oil change, air filter replacement, or spark plug replacement. The specific maintenance that needs to be performed will vary depending on the number of hours that your tractor has been in use. You can find the specific maintenance schedule for your tractor in your owner's manual.

      If you just had routine oil change and other maintenance done, then the service reminder light may have been reset incorrectly. To reset the service reminder light, follow these steps:

      1. Turn the ignition key to the "ON" position without starting the engine.
      2. Press and hold the hour meter button for five seconds.
      3. The service reminder light will flash three times and then turn off.

      If the service reminder light does not turn off after following these steps, then there may be a problem with your tractor's service reminder system. In this case, you should take your tractor to a qualified technician to have it diagnosed and repaired.
