What to do if a Kubota Tractor has black exhaust gas?
- J
  jeffreyhintonAug 21, 2025
  If you notice black or dark gray exhaust gas from your Kubota Tractor, it could stem from a few issues. The filter comp (DPF) might be clogged, requiring replacement. You may be using low-grade fuel; switch to the specified fuel. A clogged fuel filter could also be the culprit, so change it. Additionally, check for a clogged air cleaner (clean or change it) or a damaged injector (replace it).

What causes Kubota WSM L4060 engine to overheat?
- J
  Jerry HendersonAug 23, 2025
  If your Kubota Tractor is overheating, several potential causes exist. Insufficient engine oil or coolant levels could be the issue; ensure they are filled to the prescribed level. A broken or elongated fan belt may be the problem, requiring a change or adjustment. The radiator net and fins might be clogged with dust, necessitating cleaning. Corrosion inside the radiator or coolant flow route could also lead to overheating, so clean or replace the affected parts. A damaged radiator or radiator cap would also need replacement. Finally, using unsuitable fuel can cause overheating, so use the specified fuel.

Why is the Kubota WSM L4060 output deficient?
- S
  Sara RasmussenAug 26, 2025
  If your Kubota Tractor has deficient output, it could be due to several reasons. The engine's moving parts might be stuck, requiring repair or replacement. The supply pump or injector could be damaged, also needing replacement. A compression leak could be present, necessitating an examination of compression pressure and subsequent repair. The air cleaner might be clogged (clean or replace the element). There could be air leakage from the compressor discharge side, in which case you should replace the turbocharger assembly. Lastly, the breather hose or CCV might be clogged with ice, requiring you to melt the ice or replace the affected parts.

  If your Kubota Tractor's engine revolution isn't smooth, several factors could be at play. The fuel filter may be clogged or dirty, requiring a change. The air cleaner might be clogged, needing cleaning or replacement. A fuel leak could be present due to a loose injection pipe retaining nut, so tighten it. The fuel supply pump might be malfunctioning, necessitating replacement. The injector could be stuck or clogged, also requiring replacement. Issues with the turbocharger, such as a worn bearing, bent shaft, or damaged fins/components, would require replacing the turbocharger assembly.
