While mowing the lawn, you have some time to let your thoughts drift off, so it is inevitable to think about lawn mowers. That is when you start thinking about different types of mowers and the motors that drive them, like brushless motors, which you likely read about somewhere.

You might have wondered what these types of motors are and what the differences between brushless and brushed motors are, and whether or not they are any better. We take a look at them in this article to have a better understanding of what these motors are about and how they work.

So, read on to find out for yourself whether brushless lawn mowers are worth the trouble to consider buying a new one.

What is a Brushless Lawn Mower?

In short, a brushless lawn mower is a lawn mower that makes use of a brushless configuration inside the motor to produce the electric current. Brushless lawn mowers also have the ability to adjust automatically to increase power usage depending on how much is needed at a certain time.

So, you can easily go from short grass to longer grass and the lawn mower will simply use more power from the motor to compensate. When it senses that less power is needed for the work at hand, it will simply put out less power.

It uses a brushless DC motor to turn the blades, and makes use of new advanced technology to increase the efficiency of the motor. This technology will also help to improve the overall life span of the motor to last longer and provide better service to the user.

What you might be concerned about is that these lawn mowers are a bit more expensive than the standard ones. However, keep in mind that they will require less maintenance. What is the hype about these lawn mowers? If it costs you more in the end, is it not better to use the standard ones?

Are these brushless lawn mowers better than the standard ones, or is it just a sales gimmick to make you buy them? The simple answer here is: yes, they are better. We will take a look at all of the reasons why they are better.

Benefits Of a Brushless Lawn Mower

There are a number of positive characteristics in a brushless lawn mower that may outweigh the higher price tag attached to it. We take a look at some of them so that you can understand why they are a better option to use for mowing your lawn.

Benefits Of Brushless Lawn Mowers

  • Brushless motors found inside these lawn mowers do not require regular maintenance to keep on running and are, therefore, easier to maintain.
  • You will also have much less wear on a brushless motor than is the case with a brushed motor.
  • These type of motors run much quieter than brushed motors, making it easy to use your lawn mower in populated areas.
  • A brushless motor comes with a much higher power output, making the lawn mower easier to use on different surfaces.
  • As mentioned, it comes with smart technology to sense when more or less power is needed to do the job.
  • Because of all the features already mentioned, they are more energy-efficient and also save you money on energy bills and maintenance fees.

All these features will make the lawn mower last longer and be more efficient in many different lawn cutting applications.

The Negative Of Brushless Lawn Mowers

As it is with everything created and marketed by humans in this world, even the greatest products usually have some negative downsides. Such is the case with these brushless motors found in lawn mowers.

  • Even though these motors last longer, breakage may occur, and they will be very expensive to repair. What’s more, these repairs can only be done by experts.
  • They cost about 30% more than stand brushed lawn mowers, so the initial cost is a bit higher for a brushless lawn mower.

There are not many negative factors for these brushless lawn mowers, except for the fact that they may cost a bit more. Depending on what your lawn cutting needs are, these downsides are not really enough to swing the scale to the negative side.

If you have a small lawn or live in a place that is not densely populated, the extra cost may not be an option. If you have a large lawn to cut with different types of surfaces, you may definitely consider buying a brushless lawn mower.

This is also true for those living in populated areas and who love to mow the lawn early in the morning when the neighbors are still sleeping. A quiet lawn mower might be the better choice to not aggravate the neighbors.

How Do They Work?

Without getting too technical, we will explain in layman’s terms how these motors operate compared to brushed motors. First of all, they do not have a commutator and brushes that need to be replaced on a regular basis, as with brushed motors.

The benefit of this is that there is much less friction inside the motor when voltage drops occur, which may damage internal parts. These motors use different digital technology to generate linear power output to the motor so that it can work properly.

Let’s just say that they do not use brushes, causing less friction, which makes the brushless motor more powerful and efficient. Less friction will in turn reduce heat build-up, which will make the motor run cooler and last much longer.

That feature also makes the motor run quieter. Plus, fewer sparks are created while the motor is running, for better energy efficiency. A brushed motor is made with simple electrical operations, whereas the brushless motors make use of complex electronics to control the output of the stationary magnets.

Because these brushless motors are much more complicated to design and build, they are more expensive than brushed motors. To sum this up, the brushless motor runs cooler, therefore the motor will in turn have a boost on overall performance.


So, now that you know what a brushless lawn mower is, you can decide which one will be the best option for you. The next time you are out there busy mowing, or with friends or colleagues, you will know what they are talking about.
