The short answer is that yes, a lawn mower can indeed explode, if the conditions are right. While a lawn mower is unlikely to explode because it is blowing white or any other color of smoke, it’s also important not to ignore the warning signs when they occur. A lawn mower can explode if it catches on fire due to the mixture of flammable oil and explosive gasoline surrounding the engine. And though instances of exploding lawn mowers are uncommon, and lawn mower white smoke is not a direct indication of that, it’s wise to keep your unit well maintained and working smoothly.
