 How to Choose a Quiet Gas Lawn Mower

When choosing a quiet lawn mower, there are certain factors you ought to consider. These features here will help you choose the best gas lawn mower for your needs.

Noise Level

As mentioned above, gas lawn mowers are not very quiet by design. A standard gas-powered lawn mower can produce about 95 dB of noise. Which is dangerous for the human ear without any hearing protection in place.

That’s why is important to get something slightly lower in noise and use ear protection when operating the gas lawn mower.

Push Mower vs Self-Propelled Mower

These types of gas lawn mowers can easily be distinguished by the way they are started. The self-propelled gas lawn mower has a gearbox that can automatically push either the front or rear wheels to move forward. While the push mower operates on your sweat.

Self-propelled mowers are the best option for hilly and uneven terrains. On the other hand, push mowers are ideal for flat yards if unless you are strong enough to push through the hill and slopes with your manpower.

However, self-propelled mowers tend to be on the heavier end and are also more expensive than a traditional push counterpart. There are two kinds of self-propelled mowers, these are; front-wheel drive and rear-wheel drive. Your choice will depend on the type of terrain you are dealing with.


It’s novel to have a quiet lawn mower but if it cannot serve its purpose properly, then it’s of no use. A mower with various height positionings will help you navigate and sweep through a lawn with different kinds of grass easily.

Lawnmowers vary in the noise they make. Unfortunately, most of the mowers are quite loud. You can, however, choose to buy quieter lawn mowers or soundproof the one you have.

When mowing, you should also wear protective gear for your ears.

Most mowers produce a noise level of around 90 dB (Decibel). This is high than the recommended noise level for your ears. No one should be subject to this noise level for over eight hours. Here are some techniques you can use to make your lawn mower quieter.

Work on Your muffler

Due to the high levels of noise that lawn mowers make, most of them have a muffler installed on the engine. It is most specifically fixed at the exhaust port. This muffler forces the loud sound from the engine to pass through the noise-canceling chamber on the muffler.

This also produces pressure on the engine to work at its maximum horsepower. But as time goes on the muffler may crack causing it not to cancel the noise effectively. Therefore, resulting in a louder lawn mower. You can change it by getting a new muffler to replace it. Or better still, you can change your mower muffler and get a more powerful muffler to lower the noise levels more.

Work on the Deck

To reduce the noise coming from the blade, rock pings, and vibrations, then you have to quiet the deck. The best method you can use to quiet the lawn mower deck is to use a sound-deadening material. You can use the same sound-deadening materials used on vehicles. Such as Noico, Dynamat, Kilmat, etc. Check out this article on Kilmat vs Dynamat sound-deadening materials.

Install Engine Silencer on Your Lawn Mower

Silencers work the same with combustion engine mufflers in automotive engines. The silencers reduce the noise produced during combustion by the water lawnmower engine.

Engine silencers are mainly into three categories. Every category determines the level of noise reduction applied to your lawn mower.

Absorptive Silencer: This is a silencer with E glass or fiberglass insulation in its internal construction. When connected to the lawnmower exhaust, it dampens the vibration and sound produced by the engine. Absorptive silencers are perfect for reducing the high-frequency noise level lawnmowers.

Reactive silencers: They should be connected by a tube to the engine exhaust. The muffler has three internal chambers. Exhaust noise bounces between the chambers and reduces the noise produced by the lawn mower. Reactive silencer should be used to reduce low to mid-level noise

Combination silencer: As the name suggests, it combines the technology of absorptive and reactive silencers. It’s fixed like all the other silencers. A combination silencer reduces all levels of sound frequency from the lawnmower.

Wear Hearing Protection

As already established above, the noise levels of lawn mowers is very high even if you choose a quieter lawn mower, there will still be high noise, especially with the gas models. They are pretty noisy. That’s why is always good to wear ear hearing protection when working with lawn mowers.


How Long Does Lawnmower Engine Last?

With proper maintenance, an average lawn mower lasts 8 to 10 years. A lawn mower that is not well maintained may last one-half that time.

Does Wet Grass Dull Lawn Mower Blade?

With continuous use, lawn mower blades are bound to get dull, irrespective of whether they are used to cut wet or dry grass. This happens to all shape metallic objects that are used for cutting things.

However, remember that mowing wet grass is not a very healthy activity for your lawn and strains the lawn mower. Since wet grass bends over, you can’t mow it correctly and when it dries, it will stand up straight again, leaving your lawn look uneven and hideous.

Wet grass can also get stuck to the desk and bog down the engine. The wet grass can even leave marks on your clothes making them difficult to wash away. Generally, it’s not ideal to mow wet grass.
