Have you ever wondered about cutting grass without all the noise and vibrations of a lawnmower? Some people love the power of a gas-powered engine, while others prefer electric pushmowers. There is another option people can choose, which is a brushless lawnmower.
These mowers run on battery power and work excellently in quiet neighborhoods. They are efficient for small areas to mow for up to half an acre with ease. So what is a brushless lawnmower?
A brushless lawnmower is run by a brushless motor adjusting the power required for each cut. It uses magnets to power up and has better performance while providing more peace and less heat. The mower automatically adds torque when it is in thick areas and winds down when less endurance is needed.

How Does the Brushless Mower Operate?
Brushless batteries lose the commutator and the brushes. The windings and the magnets are reversed in their positions. A small circuit board takes the commutator and brushes place to deliver and organize the power to the windings.
The smart controller and the circuit board monitors the battery telling it what to do. It is a brilliant device that adds power when needed and lessens where the grass is short and not as thick. The controller and circuit board run at a fast pace while the mower is in use.
The voltage drop and power’s friction touch are created by dragging next to the spinning commutator. Physical contact causes continual power loss while moving. This makes the process more potent than the brush mowers.
The technology would have called them “smart mowers,” but they still operate close to the brush mowers. They both require magnets, but the reversed process makes the brushless mowers rely more on magnetic power.
Advantages of Brushless Lawn Mowers
These are the positive things to expect when purchasing a brushless lawnmower.
- The DC batteries have feedback control which monitors the torque and speed. This benefit offers low power consumption, higher efficiency, and longer battery life in the motors that run off batteries.
- There are no carbon brushes. It reduces maintenance cost and continual humanproof69-20nt requirements of brushes.
- Brushless mowers generate more power and require less maintenance. They do not need to be cleaned up after cuts, and there are no brushes to replace.
- These eco-friendly mowers offer serenity and peace with zero noise pollution since there are no brushes. The neighborhood will love you for not waking them up in the morning or naptimes.
- They will never overheat due to the lack of brushes. This is one breakdown you will not have to worry.
- In thick grass or wet grass, the electronic sensors will send to the battery to add torque. For short grass, the battery will slow down, lessening its power.
- The battery power can cover up to cutting an acre of grass. With the control board and its technology, you can cut at a fast pace. There is no friction between a rotor and stator, so there is more power and efficiency to do the job.
Disadvantages of Brushless Lawnmowers
Not every piece of equipment is perfect. As excellent as the brushless lawnmowers are, there are a few disadvantages. Below are the downsides to be aware of.
- Compared to a brush mower, the price is much higher. A brush lawnmower will cost between $150 to $300. A brushless lawnmower averages $200 to $550.
- Some brushless mowers experience slight vibrations at a slow rate of speed during rotation. The vibrations go away after raising the speed.
- Working on the motor and wiring is not simple. Electronics and electromagnets make the mechanics more complicated and require professional assistance.
Is the Cost of the Brushless Mower Worth It?
This is a common question for people who are not familiar with this technology. Everyone who owns one has said yes, it is worth the money. The benefits allow them to use the mower whenever they see fit.
The brushless batteries are the most impressive. The copper windings are placed on the border where the motor shape is located. In addition, there is no voltage drop or friction.
The benefits are the reason for overall performance and the increases in the life of the motor. With eco-friendly technology, more people are moving toward these lawnmowers. People are becoming more aware of the surroundings and the environment.
The Lifespan of a Brushless Lawnmower
All the benefits put together to add to the greatest enjoyment of all, the long lifespan. The warranty is the same for both mowers, which is usually a year. The lifespan of the brushless mower surpasses by far the brush mowers.
Brush motors get about an average of one to 3,000 hours of operation. Brushless motors can reach the point of ten thousand hours on average. Some have reported thousands more since no brushes are there to carry.
Another issue that makes the brushless last longer is due to it never overheats. Overheating can cause many of the parts to fail in brush motors. The only limiting part is the wear and tear of the bearings.
The Difference Between Brush and Brushless Motors
A brushed motor has brushes within the battery’s organic materials. The brushes charge the commutator within the engine. The commutator gets the power source from the brushes, which is the single provider of energy that turns the rotor.
The Pros of a Brush Motor
- Construction cost is lower.
- The motor can be rebuilt.
- The controller is not necessary for fixed speed.
- The battery is perfect for extreme environments.
The Cons of a Brush Motor
- The mower can be loud and noisy due to the switching action of commutators. It continually creates electromagnetic and electrical noise through breaking inductive circuits.
- The battery runs hot.
- Maintenance is required on a routine basis.
Brushless vs. Brush
Brushless motors are 85 to 95 percent efficient, while brush motors are 75 to 80 percent efficient. The efficiency means the total power used from the engine is turning into rotational energy; therefore, less heat is lost.
The primary difference is the brush is created with carbon while the brushless use magnets to produce power. Brushless motors are better equipped.
Brushless has better performance, no friction, little to no maintenance, no requirements to replace old or worn brushes. Since brushed motors heat up, the cooling process takes a long time. The electromagnetic is in the center of the brush motor, which is the cause of the heating.
The cost of manufacturing and the parts are cheaper in a brush motor. Mechanical will always cost less than technology and electronics. They do not call the brushless mower a “smart mower” for nothing.
What to Look For When Buying a Brushless Lawn Mower
When making a new investment in a new piece of equipment, it is best to look at the positive reviews. Look for those outside the manufacturer’s website to get the most honest reviews. When you decide you are ready to purchase a brushless mower, get it from the most reputable manufacturer.
When looking at the different brands, choose the ones that have been around the longest. Try to stay away from the newer brands unless the technology and the reviews are better. Most times in competition, new technology experiments and you do not want to become the guinea pig.
Choose the best battery packs that last the longest. On average most brushless mowers can operate for up to 45 minutes. You also need to keep in mind the storage of each mower if you have the storage space.
The cost of the batteries is another thing to consider. Most operate on lithium-ion batteries, and they are expensive. Many people like to use the same name brand equipment, and the batteries may be interchangeable, saving hundreds of dollars.
What is the best brushless lawn mower to purchase?
Kobalt KMP 6080 is the bestseller because the battery charge time holds up to cut a full acre. They work best for more extensive lawns, but the best is in the owner’s circumstances.
Are all cordless lawnmowers brushless?
No. The two times of lawnmowers are brushless and brushed. Gas-powered lawnmowers have brushed motors.
Which is better, an electric mower or a brushless lawn mower?
An electric mower is cheaper, but the durability stands better with the brushless. It is always easier to cut with a cordless lawnmower, so choosing the brushless would have the better options.
