Everything You Need To Know About Brushless Lawn Mowers

If you enjoy cutting your garden or yard’s grass in the early morning hours in a quiet neighbourhood, you don’t want to start making too much noise and annoy people who are still lying in bed or savouring their day.

Perhaps your neighbours have already complained about the noise of your mower. In such situations, you must think about purchasing a brushless electric lawn mower.

A brushless mower, in addition to being quieter than the rest of the lawn mowers, also necessitates less maintenance.

Everything You Need To Know About Brushless Lawn Mowers

In this article, we will give you a definition and detailed explanation of what a brushless mower is, analyse its benefits and drawbacks, and provide details on the most effective brushless mowers available.

What Is The Definition Of A Brushless Lawn Mower?

A brushless lawn mower is essentially a mower with an electric engine that has no brushes.

An engine with no brushes is equipped with a fixed magnet as the propeller (the rotating part) and coils on the exterior.

This indicates how no power supply is required to power the engine’s mechanical system.

This eliminates the necessity for brushes, something that ultimately results in much less vibration and no power losses caused by friction.

Brushless motors were previously difficult to manufacture and significantly more costly because of their more intricate engine coordination.

Utilising brushless mowers can significantly increase the battery performance of the machine, make it more resilient, and require less upkeep.

The Advantages Of Utilising A Brushless Lawn Mower

Smoother Mowing

Lawn mowers that have no brushes are not as noisy as those with brushes and can thus make mowing a more quiet and serene task.

As a result, a brushless mower is more suitable for usage at any time during the day. Certainly, the motor is not the sole thing that creates noise in a lawn mower.

The spinning blade as well as other components produce noises too. You could perhaps consider those parts too in order to render the mower as quiet as you can.

Minimized Overheating

A brushless lawn mower does not overheat at the same speed and rate as those with brushes do.

Because the coils are located on the exterior of the engine, they can drop their temperature down faster.

Modify as needed: A brushless mower has a far more advanced electronic motor control system. Depending on the model and sort of lawn mower, the engine setup can be adjusted to meet the owners’ needs.

It can, for example, go slower when starting to move through a narrow lawn and accelerate once starting to move through denser parts.

This shows that you can easily save power when using a battery-powered lawn mower. This becomes more challenging and inefficient when using an electronically controlled mower with a brushed engine.


A brushless mower is more effective, as it can complete harder jobs easily and without any slowdowns.

 Because the coil is on the exterior and can be produced in sizes too big, it is also simpler to build more efficient motors.

A brushless lawn mower necessitates less upkeep than traditional lawn mowers. It’s not necessary to sanitise and install new brushes in the same way you’d need to do on a brushed lawn mower on a regular basis.

Improved Battery Efficiency

Using the right battery packs, brushless mowers can cut and trim more acres of land.

The power is spent more effectively because there isn’t any power loss between the rotor and stator. In cases of harsher conditions, the mower continues to work more efficiently when there is no rubbing.

The Drawbacks Of Utilising A Brushless Lawn Mower

Everything You Need To Know About Brushless Lawn Mowers


A brushless mower will cost you more than a mower with brushes.

Brushless lawn mowers employ a more intricate advanced technological control system, which functions similarly to a microcomputer. This should raise the price a little.


When the motor is running at slower revs, minor vibrations could occur. This seems to be natural, so they ought to diminish as the speed is increased.


The energy intensity can often compare to or approach the natural vibration frequency of many other components, which is probably going to result in some resonant frequency.


The machine becomes rather complex when tools are operated by an engine.

Many components could fail as the system becomes more complicated. However, contemporary brushless engines are pretty durable.

A Comparison Between A Brushless And The Brushed Lawn Mower

The discussion about whether to purchase a brushless or a brushed lawn mower is typically settled by examining a few key contrasting factors.

We believe the best approach to evaluate these two is by considering the following aspects:


Brushless engines usually have a performance of 80-90%, whilst brushed engines have a performance of 60-75%.

It’s not like all brushed or brushless engines are built the same way, but brushless engines are undeniably more productive because of their structure.


Electricity-powered push mowers (Also check out Push Mowers Or Self-Propelled Mowers) with no cords vary greatly in their price, yet one constant is that lawn mowers that have no brushes do cost more.

Brushless engines seem to be more difficult to construct and operate, which increases the cost of the machines that are equipped with them.


The presence or lack of these vexing wee brushes matters a great deal in this situation. Brushless engines necessitate minimal upkeep over their lifetime.

Brushed engines represent the complete antithesis. They necessitate regular upkeep (primarily due to the brushes), and yet are simpler to operate.

Regardless of all that, it is important to note that brushed engines do not survive as much as brushless ones do.

In fact, engines with no brushes can even last 5-10 times longer than their competitors, even without any service or upkeep.

Operating A Brushless Lawn Mower

The rotary component of a brushless engine is a fixed magnet. The engine’s coil will encircle one such rotary magnet. A brushed engine is the polar opposite of something like that.

The rotary component of a brushed engine is a coil, which is surrounded by a fixed magnet. As a result, the magnet will not spin in such a particular instance.

The issue with brushed engines is also that electrical energy must be supplied to the rotating component.

Brushes are used by the engine to accomplish that. However, even these brushes are put under a great amount of stress, which means that they require more upkeep.

When it comes to a brushless engine, the coils are divided into numerous sections, all of which are located on the exterior.

In such a situation, it is simple to generate electricity with a few wires. The issue with brushless engines would be that the coils must be employed at exactly the proper moment in order for the fixed magnet to spin.

To accomplish this, the engine has a sensor that tracks the status of the magnetic circuit, and the control system seems to use this status to activate the appropriate coil at the appropriate moment.

Brushless engines offer more benefits. Because the copper coils are located outside of the motor game plan, there is room to expand them. A brushed engine does not have this alternative.

Furthermore, brushless engines do not suffer from the abrasion and power loss that brushed engines seem to.

Brushless Mowers And Their Longevity

Brushless engines have proven to be better compared to brushed engines in a variety of ways. And how about their average lifespan, one might ask? Do brushless motors sacrifice longevity in order to be more productive?

The answer to that would simply be no, they do not.

Brushless motors typically outlast brushed motors. Brushed motors have a life expectancy of 1,000-3,000 hours under comparable circumstances, whilst brushless engines have a much longer life expectancy.

Brushless engines typically have an operational life of 10,000 hours, if not more.

The main reason behind a brushless mower’s strength and durability would be that it produces less tension and wear in the engine and fewer overheating cases.

Are Brushless Land Mowers Worth Their Money?

Another critical question is whether the high price of a brushless mower is merited. Yes, these mowers are worth the additional cost. Let’s look at why.

Brushless engine mowers have considerable benefits over brushed engine mowers. The most notable seems to be improved productivity and reduced maintenance requirements.

Since the copper coils are located on the motor’s exterior, they can be made bigger. This increases the engine’s capacity, which a brushed engine cannot achieve. Furthermore, they have very low friction and no power loss.

As a result, the advantages of a brushless engine outweigh the additional cost.

The Bottom Line

Brushless mowers are clearly superior in a broad range of ways. They are much more functional, produce less vibration, necessitate fewer repairs and services, and provide a more pleasant user experience.

Portable electric lawn mowers have the benefit of lasting longer, but they are more expensive. Still, they offer better performance, more years of life, and fewer needs for upkeep.

Therefore, brushless lawn mowers are definitely the best option.
