Why is my Kubota B3350HSDC emitting black exhaust gas?
- DDr. 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.
