Are Mulching Blades Louder? (Solved & Explained!)

Yes. Mulching kits do make your mower louder, but on the bright side they also produce less dust than a high lift or standard blade assembly. This is because mulching blades are heavier and designed to cut finer than your standard blades and it basically boils down to more work, more weight, and more noise!

Today we’ll talk about mowers and why they are so loud – we’ll go into common issues that cause this, as well as upgrade options that can help, and which companies produce the quietest engines.

 Let’s take a look at the most common questions asked about loud lawnmowers!

How noisy is a lawn mower?

A lawn mower, on average, produces about 70 – 90 decibels of sound, with push movers being in the 70 – 80 range and riding mowers at 90. To give you a comparison, a conversation between friends averages about 60 decibels, while a decent rock concert will rank in at about 120 decibels.

Why are lawn mowers louder than cars?

The reason lawn mowers are so much louder than cars (with their bigger engines) has to do with the mufflers which are used. Lawnmowers typically employ Absorptive type mufflers, which are typically fabricated from plastic and not as efficient. You get more power, due to minimal gas flow restriction, but they are also louder than they could be with a better muffler installed.

Why is my mower deck so loud?

If your mower was quieter before, then it may be that the mandrel bearings are wearing out. Take a note of the vibration of the mower – if it has increased, then the mandrel bearings may well be the culprit. When they loosen from eventual wear and tear, the first symptom is heavier vibrations with normal use of your mower.

Why does my lawn mower sound louder?

That will depend on the noise. If your mower is rattling, then it may be a loose blade assembly. You can also check the muffler to see if it is rusted or otherwise damaged, as this will definitely increase the volume. If you haven’t changed the oil regularly, then you will sometimes get knocking sounds from your mower as well.

How can I make my mower deck quieter?

The easiest ways to reduce noise on your mower (provided that it is not related to damage) is to soundproof your current deck or to simply install a better-quality muffler. Note – if the new muffler restricts the gas flow enough, you may lose a little power, so be sure to research the make and model of your mower to find the most compatible muffler.

Do lawn mowers have mufflers?

Your lawnmower will have a muffler installed, but the quality of the muffler is going to vary from brand to brand. That said, you can replace the muffler with a more powerful one, just be sure to check the make and model of your mower to ensure that the new muffler will not have a negative impact on your power and performance.

Where is the muffler on a lawn mower?

Typically, the muffler is going to be located close to the cylinders, but you’ll want to consult your owner’s manual to be 100% sure. Once you’ve located it, if you remove the muffler and shake it then you should not hear much noise. If you hear debris rattling around inside it, then it may well be time to replace your muffler with a new one.

Can you put a muffler on a lawn mower?

You can, just be sure to check the current muffler that you have before you select a new one. Depending on the model of your mower, the muffler may be of the cheap, plastic variety, or it might well be a higher end muffler specifically designed for your model.

For best results, consult your manufacturer – they may well provide more efficient options that are specifically designed for your mower.

How do I make my lawnmower louder?

If you want to make your mower louder and it currently has a metal muffler, you could replace that with a plastic absorptive type muffler. This will likely give you a small power boost but the mower will definitely be louder than before.

Why are riding lawn mowers so loud?

That will depend on the make and model, as well as the type of muffler which your riding mower employs. Check the muffler to see if it is a plastic absorptive-type muffler and if this is the case, then you might be able to upgrade to a more efficient, metal muffler to reduce the overall noise.

How loud is a riding lawn mower?

On average, most riding lawn mowers will be at around 90 decibels of sound. Anything above 70 decibels can cause hearing damage with prolonged exposure, so it is a good idea to use earplugs or earmuffs when you are mowing on your riding mower to help reduce the chance of damage.

Are battery lawn mowers quiet?

Battery powered lawn mowers are much quieter than standard and riding mowers, measuring in at about 75 decibels during normal operation. They are also quite cost efficient both in operation and required maintenance, but the trade-off is that you get less overall runtime.
