Greenworks Pro 80V 21 Inch Cordless Lawn Mower Review


Greenworks Pro 80V cordless mower’s powerful brushless motor, long-lasting run time, and smart adjust that responds to the length and density of the grass make it a solid choice. It’s extremely maneuverable and designed for quick ground covering.

The Greenworks Pro 80V cordless mower is a standout among standard mowers, thanks to several factors, including the brushless motor as well as long runtime.

This lawnmower has been praised for its quiet operation, ease of use, good runtime, and low battery consumption. It can handle any lawn and cut through very tall grass.

But can it compete against corded and gasoline-powered alternatives as a battery-powered cordless machine?

Features Review

Let’ review the different features of this product.


Battery & Runtime

The most impressive aspect of choosing this cordless self-propelled lawn mower is the battery. Greenworks Pro 80V cordless mower comes with a 4.0Ah battery. The battery is made of lithium-ion battery technology, which is the gold standard in the portable battery sector. Electric vehicle makers such as Tesla use this type of battery. These batteries are usually much more energy-efficient and rapid-chargeable than the traditional lead-acid batteries.

When run on a normal grass lawn, the fully charged battery can provide a runtime of up to 60 minutes. It is enough to cover up to an acre of land. Once it’s fully charged, the mower can run continuously for 6o minutes. If you wish to cover a lot more ground or if you own a larger lawn, you might consider getting an additional battery so that you can use the extra one when a battery finishes its juice. It’s very handy because it only takes 30 minutes to charge the 80V battery fully.

Pro-tip:  To make sure that the batteries of your mower last longer, our advice is: you should make a habit of taking out the batteries when you are not using the mower. It will ensure the longevity of the batteries and prevent the decrease of runtime.


Deck Size

Most of the battery-powered lawn mowers in the market have a smaller deck size compatible with their battery & engine power. Greenworks Pro 80V cordless mower has a superior battery and motor technology; it can afford a bigger cutting deck than most battery mowers. The width of the cutting deck of this mower is 21 inches which is above average for battery-powered mowers. It can even rival some of the gas-powered lawnmowers!

Having a 21-inch cutting width makes your life easier; because you can cover more space in one pass and traverse your lawn in less time. However, bigger decks come with their problems. You will have a hard time maneuver a mower with a bigger deck; you will face difficulty turning the mower and moving along the curved space. Fortunately, Greenworks Pro 80V cordless mower has a perfect size: not too big, not smaller either.


3-in-1 Feature

What 1-in-1 feature, you ask? It has to do with the grass clippings. When you mow your lawn, you have three options for grass clippings: (1) keep the grass bits in the ground, (2) throw them sideways, & (3) collect them in a bag. Most mowers do not provide you with all three options. But Greenworks Pro 80V cordless mower does.

This mower comes with a rear bag where you can collect the grass clippings. The bag is big enough to store a large volume of grass bits. There is a discharge opening on the side of the deck, between the front and rear wheels. If you want to throw away the grass, you have the freedom to do so.

But the best option to manage the grass clippings is to keep them in the soil. See, the mower has the mulching technology that makes the grass clipping even smaller. The grass bits that are left on the soil quickly disintegrates into nutrients by microorganisms. These nutrients then provide nutrition to the grass, which helps grow healthy grass.


Push Button Start

The mower’s pull cord is gone in favor of a push-button ignition. This mower is more user-friendly for those in a hurry or who have issues with their backs and shoulders.

This design has one major concern: the reliability of the push-button. It works quickly and without hesitation, unlike other ignition methods.

This design is also easier to teach your children how to mow the lawn. You’ll find it easier to help your kids with their summer chores because there are fewer steps to remember, and it’s much simpler to start.


Cutting Power

A good lawnmower should have cutting power. This is where cordless mowers, as well as corded electric ones, often fail. But Greenworks80V cordless mower does an excellent job in this area.

This mower detects the density of your grass and adjusts its cutting speed accordingly. Tallgrasses and weeds automatically increase the mower’s power. The mower will cut a lot louder and go a lot faster. However, these faster speeds can make your lawn look a little more uneven, and you don’t want any tall grass sticking out.

When your mower is speeding up, the best thing you can do is slow down. You might even need to move back a bit to ensure that you cover the whole area. The motor will start to slow down, and then you can continue to move.

When you have tall or thick grass to cover, it’s better to use the side-eject accessory. When the grass bag is full, your motor starts running more quickly. It can be hard to discern when you should spend more time on a particular area of grass or when your motor is simply responding to a full lawn bag.


Brushless Motor

Many people talk about the fact that a brushless motor can make a tool more durable and efficient. It’s true for the Greenworks 80V Cordless Mower. General consumers aren’t aware of the benefits of a brushless mower, and not many reviewers cover this.

An electric motor operates by using a magnetic force to turn the rotating rotor. The basic principle is the same for many variations. Regardless of its design, the motor must create an outside, and inner magnetic field with a small connection called a stator. Because the outside and inner magnetic fields push against one another to turn the rotor, the connection point is critical.

The ‘brush’ motor creates a connection by using a graphite brush against a stator. The problem with a brush motor is that the graphite in the graphic can wear out, and the motor will stop working if it has no graphite. It is also less efficient than brushless designs. Brushless designs use permanent magnets and a specialized system to achieve the same task. A circuit board is required to control the entire system. They are very similar to circuit boards found in electric cars such as Tesla.

This system is more efficient overall, but the circuit board can still fail. They are generally more durable than the graphite bristle design.

Brushless motors are also less vibration. Brushless mowers are more efficient than traditional mowers, allowing you to mow for longer periods without feeling fatigued.



If you are looking to make a switch from a gas-powered mower, the Greenworld 80V Cordless Mower will be a great option. You also have more freedom than many corded mowers. One button ignition is an excellent adaptation and easier than using gas pull cords.

With a foldable handle and a compact profile, storage is easy with this lightweight deck. A larger than average deck of steel adds strength and function to the overall design.

While it may not be as robust or as efficient as a gas-powered mower, the mower still offers solid options. This mower is an excellent choice for anyone looking to purchase a push mower.
