3. Smoke coming out of the mower

Did you ever notice smoke coming out of your lawnmower? There have been instances where users have complained about this specific issue. Let’s find out why this happens.

Excessive oil can create pressure in the engine when there is too much oil in the crankcase, allowing the oil to get into the cylinder.
