When it comes to the world of lawn mowers, there are a lot of options out there. For some people, they prefer to use a lawn mower that makes as little noise as possible.

This is especially true if you enjoy mowing your lawn early in the morning. 

In these circumstances, you ought to think about purchasing a brushless electric lawn mower. A brushless mower is not only more silent than other varieties, but also requires less upkeep.

A lot of electric lawn mowers used to be mainly brushed motors. However, thanks to advancements in technology, brushless lawn mowers have become a lot more popular. 

Brushless Lawn Mower: What Is It?

Brushless motors, as their name suggests, are created to function without the need for brushes to supply energy to them. The distinction is crucial, since some electrical lawn mowers employ brushed motors.

Due to their more complicated motor management, brushless motors used to be difficult to manufacture. This then caused them to be significantly more expensive.

They have, however, begun to become more widely accessible, as technology has advanced. 

How Do Brushless Lawn Mowers Operate?

To really know what a brushless lawn mower is, it is important you understand how it works. 

A magnet that rotates in the center and a coil which encircles the magnet are the two primary components of a brushless lawn mower.

The coil of the permanent magnet is constructed of several copper windings, and it has a fixed magnetism. A sensor and external wire are used by brushless motors to properly provide power to the coils.

Brushless motors operate very effectively because of this precise usage of magnets and electrical timing.

With a brushed lawn mower, over time the brushes will begin to wear out, due to the constant friction while in use. Hence, these will eventually need to be replaced. 

Why Should You Use A Brushless Lawn Mower?

Though more difficult to construct than brushed mowers, brushless lawn mowers have a number of benefits. Some of the most popular benefits are the following:

Battery Time – With brushless lawn mowers, they can handle larger yards with the appropriate battery. This is because there is no energy lost through friction between both the surrounding coil and rotating magnet. This results in batteries being used as efficiently as possible.

Quiet –  Brushless motors operate incredibly silently since they don’t have brushes or the additional friction they cause. Even though you can’t avoid the sound of your blades cutting the grass, these lawn mowers are much quieter.

Powerful – Since they are powerful, the motors can manage heavier loads without stuttering. The location of the coil in the motor is the cause of this. It is possible to loop extra wire and expand the coil by positioning it outside the rotating magnet, which further boosts the torque.

Reliable – As brushless lawn mowers don’t use brushes in their engines, they require less maintenance. As a result, the motor is more dependable and doesn’t need to be maintained by cleaning and changing the brushes.

Are There Any Downsides To Brushless Lawn Mowers?

While there are a lot of benefits to brushless lawn mowers, they aren’t perfect. As a result, if you are considering purchasing one, there are a few things you may want to keep in mind.

Price – A brushless lawn mower is more expensive than a brushed one. A more sophisticated, clever electronic controller is used by brushless lawn mowers. Thus, the price will marginally rise as a result.

Vibrations – There may be very tiny vibrations when the engine of a brushless lawn mower is operating at low speeds. This is completely normal. However, at higher speeds, this vibration disappears.

Complicated – A brushless motor requires much more complex systems to work properly. More intricate systems have more potential for failure. However, it must be acknowledged that modern brushless motors are extremely dependable.

Should You Buy A Brushed Or Brushless Lawn Mower?

You may be wondering, now that you know what a brushless lawn mower is, whether you should purchase one or go with a brushed lawn mower instead. 

The efficiency of brushless motors is normally between 80 and 90 percent, whereas that of brushed motors is between 60 and 75 percent. Although not all brushless or brushed motors are created equally.

Yet, due to their design, brushless motors are unquestionably more efficient.

Even while the cost of lawn mowers varies greatly, one thing is constant: brushless lawn mowers are far more expensive. The cost of mowers that utilize brushless motors typically goes up since they are more difficult to manufacture and maintain.

Speaking of maintenance, the maintenance needs of brushed and brushless lawn mowers differ greatly. Over the course of its life, brushless lawn mowers require incredibly little maintenance.

However, due to their intricate construction, they are far more challenging to maintain. While lawn mowers that use brushes are easy to operate and maintain, they require a lot more frequent maintenance.

This is due to the fact that brushes wear out and need to be replaced. 

Overall, brushless lawn mowers are a lot more efficient and can last 5 to 10 times longer than a standard brushed lawn mower. The only downside is that if something happens to your brushless lawn mower, they are much more difficult to fix. 


Brushless lawn mowers use a coil around a magnet to provide electrical energy to power your lawn mower to cut your grass.

There are a lot of benefits to using a brushless lawn mower as mentioned above, such as they are quieter and require far less maintenance.

However, there is still a debate about whether you should use it compared to a brushed lawn mower. 

We hope this article has been helpful. Now you should have a clearer understanding on what a brushless lawn mower is.
