  Dr. Austin MaysAug 21, 2025
  If you observe black or dark gray exhaust gas from your Kubota Tractor, it could be due to several reasons. The issue might stem from using low-grade fuel, which means you should switch to the specified fuel. A clogged fuel filter or air cleaner could also be responsible; in this case, replace the fuel filter or clean/replace the air cleaner. Additionally, deficient nozzle injection could be the cause, requiring you to repair or replace the nozzle.

  Ryan AriasAug 23, 2025
  If your Kubota Tractor's engine is overheating, there are several possible causes. Check if the engine oil or coolant levels are insufficient and fill if needed. The radiator net and fin might be clogged with dust, requiring cleaning. Corrosion inside the radiator or coolant flow route could also be the issue, in which case you should clean or replace the affected parts. Other potential causes include a damaged radiator cap or hose (replace), incorrect injection timing (adjust), or unsuitable fuel (use specified fuel).

  Jennifer SanchezSep 1, 2025
  If your Kubota Tractor is experiencing deficient output, several factors could be contributing. These include incorrect injection timing, which requires adjustment, a malfunctioning injection pump, which needs repair or replacement, or uneven fuel injection, which may necessitate replacing the injection pump. Other potential causes involve deficient nozzle injection (repair or replace nozzle), compression leak (check the compression pressure and repair), gas leak from exhaust system or air leak from compressor discharge side (repair or replace), a dirty or clogged air cleaner (clean or replace), or a compressor wheel turning heavily (replace the turbocharger assembly).
