How to fix fuel tank contamination on a Kubota BX2660

Fuel tank contamination in a Kubota BX2660 or any other tractor can lead to engine performance issues. Here are general steps you can take to address fuel tank contamination:

  1. Drain the Fuel Tank:
    • Stop using the tractor and turn off the engine.
    • Locate the fuel tank drain valve or remove the fuel line to drain the contaminated fuel from the tank. Ensure you have a proper container to collect the fuel.
  2. Inspect and Clean the Fuel Tank:
    • Inspect the interior of the fuel tank for debris, water, or any other contaminants.
    • Clean the tank thoroughly by wiping or flushing out any residue, sediment, or foreign materials.
  3. Replace the Fuel Filter:
    • Install a new fuel filter to prevent contaminated fuel from reaching the engine.
    • Consider replacing the primary and secondary fuel filters to ensure comprehensive filtration.
  4. Inspect Fuel Lines:
    • Inspect fuel lines for signs of contamination, clogs, or damage.
    • Replace any damaged or compromised fuel lines.
  5. Flush the Fuel System:
    • After replacing the fuel filter, turn the ignition key to the “ON” position without starting the engine. This will allow the fuel pump to circulate clean fuel and flush out any remaining contaminants.
  6. Clean or Replace Injectors (if necessary):
    • If contamination has reached the fuel injectors, they may need cleaning or replacement. Consult the manufacturer’s guidelines or seek professional assistance for this task.
  7. Use Fuel Additives:
    • Consider adding a fuel treatment or conditioner to the tank to prevent future contamination and improve fuel stability.
  8. Check for Water Separators:
    • Some fuel systems have water separators. If your tractor has one, drain any accumulated water according to the manufacturer’s instructions.
  9. Verify Fuel Quality:
    • Ensure that the new fuel added to the tank is clean and free of contaminants. Use fuel from reputable sources.
  10. Regular Maintenance:
    • Implement regular maintenance practices, including changing fuel filters at recommended intervals, to prevent fuel contamination in the future.

How to diagnose and fix battery issues on a Kubota BX2660

Diagnosing and fixing battery issues on a Kubota BX2660 involves a systematic approach to identify the root cause and implement the necessary solutions. Here are steps to follow:


  1. Visual Inspection:
    • Check for visible signs of corrosion or damage on the battery terminals and cables.
    • Ensure the battery is securely mounted and there are no loose connections.
  2. Voltage Check:
    • Use a multimeter to measure the voltage across the battery terminals. A healthy battery should have a voltage of around 12.6 volts or higher.
  3. Load Test:
    • Perform a load test using a battery load tester. This will assess the battery’s ability to deliver power under load conditions.
  4. Charging System Inspection:
    • Check the alternator and voltage regulator for proper functioning. The alternator should charge the battery while the engine is running.


  1. Clean Battery Terminals:
    • If corrosion is present on the battery terminals, clean them using a mixture of baking soda and water. Ensure a tight and clean connection.
  2. Tighten Connections:
    • Ensure all battery connections are tight and secure. Loose connections can lead to electrical issues.
  3. Recharge the Battery:
    • If the battery voltage is low, recharge it using a battery charger. Follow the manufacturer’s guidelines for charging.
  4. Replace the Battery:
    • If the battery fails the load test or doesn’t hold a charge, it may need replacement. Choose a battery with the correct specifications for your Kubota BX2660.
  5. Inspect and Test the Alternator:
    • Check the alternator for proper operation. If it’s not charging the battery, it may need to be replaced or repaired.
  6. Check the Voltage Regulator:
    • Ensure the voltage regulator is functioning correctly. A malfunctioning regulator can lead to overcharging or undercharging of the battery.
  7. Inspect Wiring:
    • Examine the wiring between the battery, alternator, and starter for any signs of damage or wear. Replace or repair damaged wiring.
  8. Install a Battery Tender:
    • If the tractor is not in regular use, consider using a battery tender to maintain the battery charge.
