Frequently Asked Questions (FAQs)

1. Can you run a lawn mower without a muffler?

Yes, you can run a lawn mower for a short period without doing any significant damage to your lawn mower. It will almost certainly run significantly louder, so it's a good idea to wear ear protection.

2. How long does a lawn mower muffler last?

Generally, this happens after 1-2 years, although this time frame obviously depends on how frequent you mow your lawn. When you decide that it's time to change the muffler, there are some considerations you should make.

3. What does a lawnmower muffler do?

A muffler's job is to reduce that exhaust noise and to prevent exhaust sparks from existing and igniting dry grass, leaves or debris. After a season or two, soot build-up and cracks or holes can cause the muffler to stop working properly.
