Why is my Kubota WSM L3540-II Tractor emitting black exhaust?
- LLauren WagnerAug 20, 2025
If your Kubota Tractor is producing black or dark gray exhaust gas, it could be due to several reasons. You might be overloading the tractor, so try decreasing the load. Using the specified fuel is important; low-grade fuel can cause this issue. A clogged air cleaner can also be the culprit, so clean or change it. Additionally, a clogged fuel filter should be changed. Finally, deficient nozzle injection can lead to this problem, requiring you to repair or replace the nozzle.
