Why is there excessive black smoke in the exhaust of my Toro Tractor?
- KKenneth Lewis MDAug 26, 2025
Excessive black smoke in the exhaust could be due to several reasons. If the engine is under an excessive load, reduce the ground speed of the machine. Dirty air cleaning system elements may also be the cause, so service them. Additionally, improper fuel in the fuel system can lead to black smoke, so drain and flush the system, then add fresh fuel.
