He also said that it is not for wildfire prevention, but part of the noise reduction features.

He also said that if you remove the arrestor (noise suppressor) it reduces the back pressure and can cause damage to the motor over time.

Now I hear some people removed it or drilled a hole in it. I wish I could find the unbiased facts. Yes, there is a thread about this on the golf equipment forum but I would like to hear some knowledgeable facts about the topic. Does anyone have some or maybe long term experience following a modification?


Not clogged just restricting exhaust gas getting out. If it was clogged it wouldn’t run. IMO it will never cause damage to lawnmower engine if removed . Running it restricted will most likely cause damage to engine due to it overheating.
