Greenworks 40V 16″ Brushless Cordless Lawn Mower review

Have we ever wished mowing our yard felt less like a chore and more like a quick, quiet routine we can actually live with week after week?

What Is the Greenworks 40V 16″ Brushless Cordless Lawn Mower?

When we pick up the Greenworks 40V 16″ Brushless Cordless (Push) Lawn Mower, we are getting a compact, battery-powered mower designed for small to medium-sized lawns. It comes as a complete kit: mower, 40V 4.0Ah battery, charger, and a grass collection bag, so we can start mowing right out of the box without buying anything extra.

This mower runs on a 40V lithium-ion system that works with more than 75 other Greenworks tools, which is useful if we plan to build a whole set of cordless yard tools around one battery platform. It is built to be simple, light, and easy to maneuver, especially for yards up to about half an acre.

Design and Build Quality

When we first look at this mower, the main impression is that it is compact and thoughtfully laid out. It is clearly built for ease of handling rather than brute force, which suits typical residential lawns where agility and convenience matter more than raw power.

The 16-inch cutting deck is smaller than full-size gas mowers, but that compact size works in our favor in tight spaces, around landscaping, and along fences. The materials feel solid enough for regular home use, and the layout of the controls and levers is intuitive, even for those of us not very mechanically inclined.

Compact 16″ Deck for Tight Spaces

The 16-inch deck might seem modest on paper, but for small to medium yards, it is actually a smart compromise. Instead of wrestling a heavy, wide mower around obstacles, we can steer this one more like a nimble cart.

We might take a bit longer to mow a wide-open half acre compared with a larger deck, but in most suburban or urban yards—where flower beds, trees, and garden features are common—the smaller width helps us get an even cut without constantly backing up and repositioning.

Lightweight Construction

Weight is one of the first things we notice when we push this mower. It is light enough that many of us can move it around the yard, up small slopes, and in and out of storage without straining.

This lighter build means:

• Easier maneuvering around obstacles
• Less fatigue during longer mowing sessions
• Simpler storage and transport if we need to move it to another property

For those of us who have struggled with heavy gas units in the past, this feels like a welcome change.

Performance and Cutting Quality

Performance is where a mower either justifies its place in our garage or becomes something we regret buying. With the Greenworks 40V 16″ mower, the combination of a brushless motor, decent battery runtime, and adjustable cutting height comes together to deliver consistently good results in the right type of yard.

The mower is not aimed at huge, rough fields or tall-overgrown grass, but rather regular residential turf that we cut on a weekly or bi-weekly schedule. Used that way, the cut quality is clean and predictable.

Brushless Motor Advantages

The inclusion of a brushless motor is one of the standout features here. Compared with traditional brushed motors or small gas engines, brushless technology offers several practical benefits that we actually feel while using it.

• More torque: We get better power transfer to the blade, helping maintain blade speed under normal cutting loads.
• Quieter operation: Noise is noticeably lower than traditional gas mowers, making early morning or evening mowing more neighbor-friendly.
• Longer life: Brushless motors have fewer wear parts, which generally means better long-term reliability and fewer maintenance headaches.

In practice, this means we can cut typical lawn growth without the motor constantly bogging down, especially when the grass is not excessively tall or wet.

Runtime and Battery Performance

With the included 40V 4.0Ah battery, we can expect up to about 30 minutes of runtime under normal mowing conditions. Of course, real-world runtime varies based on grass thickness, height, moisture, and how fast we walk.

For a small yard, those 30 minutes may be more than enough to finish in a single pass. For a medium or near half-acre yard, we may either:

• Mow in segments (front yard one day, back yard another), or
• Invest in a second 40V battery for continuous mowing

The charging time of about 120 minutes from empty to full is reasonable. If we keep the battery on the charger between uses, we usually have a full charge ready for our next mowing session.

Ease of Use and Handling

A mower can have all the technology in the world, but if it is awkward to handle, the experience quickly becomes frustrating. This Greenworks model leans heavily into user-friendliness, especially for those of us who prefer a “grab-and-go” approach to lawn care.

We do not need to fuss with pull cords, gas mixing, or carburetor issues. Instead, we get straightforward battery-powered operation and controls that most of us can understand at a glance.

Push-Button Start

One of the immediate quality-of-life features is the easy push-button start. Instead of yanking a cord multiple times, we simply:

1. Insert the charged battery
2. Press the safety button or handle control (depending on configuration)
3. Press the start button

The motor comes to life without drama, which is especially appealing for those of us who dislike or struggle with pull-start mechanisms on gas engines. It also makes it simpler for multiple family members to share mowing duties.

Maneuverability on Small to Medium Yards

With its lighter weight and moderate deck size, this mower feels agile around flowerbeds, trees, and yard decorations. We can pivot and turn easily, and the push design means we can control our pace comfortably.

For flat or mildly sloped yards, pushing is straightforward and not particularly tiring. On steeper slopes, we still need to put in some effort, but the light weight helps compared to heavy self-propelled gas units.

---

Cutting Height and Adjustability

Being able to set the right cutting height for our grass type and season is essential both for lawn health and for the final appearance. This mower gives us enough adjustability to handle common scenarios in typical residential lawns.

Single-Lever 5-Position Height Adjustment

Instead of adjusting each wheel separately, we can use a single lever to choose from five cutting heights. The range goes from around 1-1/4 inch up to about 3-3/8 inches, which is versatile enough for:

• Shorter cuts for fine, manicured turf
• Medium heights for general-purpose mowing
• Higher settings during hot, dry weather to protect the grass

The single-lever system makes mid-mow adjustments quick. If we notice the mower struggling because our grass is thicker in one section, we can raise the deck in a few seconds and keep going without much disruption.

How the Height Range Feels in Real Use

In practical terms:

• The lower settings are suited to well-maintained lawns that we mow frequently, where we want a clean, tight finish.
• The middle settings tend to work best for everyday use—offering a good balance between appearance and lawn health.
• The highest settings help us handle slightly taller growth or protect the lawn in harsher conditions without scalping or stressing the grass.

For most of us, we will likely settle into the middle of the range for regular weekly mowing and shift up or down as seasons and weather change.

2-in-1 Function: Mulching and Bagging

Different yards and different seasons sometimes call for different cutting methods. The Greenworks 40V 16″ mower supports two main modes: mulching and rear bagging, which gives us some flexibility depending on how we prefer to manage clippings.

Mulching Mode

In mulching mode, the mower recirculates clippings under the deck, cutting them into smaller pieces and dropping them back into the turf. This can be a great option if:

• We want to return nutrients back to the soil
• We prefer not to deal with bagging and disposing of grass
• Our grass is not overly tall or wet

Mulching works best when we mow regularly so the clippings are short and break down quickly. If we tend to let the lawn grow too long between cuts, mulching can sometimes leave visible clumps, especially in moist conditions.

Rear Bagging Mode

The rear bagging option is ideal when we want a very tidy, clean look or when the grass is a bit longer than usual. The included grass collection bag attaches to the rear and catches clippings as we mow.

We might prefer bagging when:

• We are mowing for the first time in the season and grass is uneven
• We want to prevent clippings from blowing into walkways or flowerbeds
• We are cleaning up leaves or debris mixed into the grass

We will need to empty the bag periodically, especially in dense or higher grass. However, for those of us who like a meticulously clean finish, bagging is a strong option to have.

---

Noise Level and User Comfort

Switching from gas to electric can be a relief for our ears. With the brushless motor and battery operation, the noise level is significantly reduced compared with typical gas mowers.

Quieter Operation

While it is not silent, the acoustic profile is more of a steady hum and blade noise rather than the harsh roar and exhaust note of a gas engine. This makes early morning or evening mowing less intrusive, both for us and for our neighbors.

We can still hear the blade working through thick grass, and we should still protect our hearing during extended sessions, but the overall experience is far more comfortable and less fatiguing.

Vibration and Physical Strain

Without a combustion engine, vibration is also lower. That means:

• Less tingling in our hands after longer mowing sessions
• A more relaxed grip on the handle
• Reduced fatigue, especially when combined with the mower’s low weight

Most of the physical effort comes from pushing the mower, not from bracing against engine vibration or wrestling with a heavy machine.

---

Battery System and Compatibility

One of the major advantages of this mower is that it is part of the Greenworks 40V system. For us, that means the battery is not just a single-purpose item; it can power over 75 compatible tools if we choose to expand our setup.

4.0Ah Battery and Charge Time

The included 4.0Ah battery offers:

• Up to 30 minutes of typical runtime
• A recommended charge time of around 120 minutes

For single-battery users, a routine like this usually works:

• Mow our yard
• Put the battery on the charger immediately afterward
• Have it fully ready next time we need to mow

If we already own or plan to add more 40V tools (like trimmers, blowers, or chainsaws), we may consider owning multiple batteries so we can swap and keep working seamlessly.

Compatibility with 75+ Greenworks Tools

Because the 40V battery works across many tools in the Greenworks ecosystem, we can build a coordinated, cordless yard-care setup. For example, we might run:

• This 16″ mower for the lawn
• A 40V string trimmer for edging
• A 40V blower for clearing clippings from sidewalks and driveways

Sharing batteries reduces clutter, saves money compared to buying separate power systems, and simplifies charging and storage.

Setup, Storage, and Maintenance

Owning a mower is not just about the cut; it is also about how much time and effort we spend keeping it ready to go. This is where cordless, brushless models shine compared with gas options.

Initial Setup

Out of the box, we typically need to:

1. Attach or unfold the handle (usually with simple knobs or bolts)
2. Insert the grass bag if we plan to bag clippings
3. Charge the battery fully (about 120 minutes)
4. Insert the battery and we are ready to mow

We do not have to worry about adding oil, filling a gas tank, or tuning anything. This straightforward setup makes it usable for many of us within an afternoon of arrival.

Storage Considerations

The mower’s compact size and lighter weight make it easier to:

• Store in smaller sheds or garages
• Lift over a small lip or into a storage corner
• Move out of the way when not in use

Some Greenworks models have foldable handles to reduce their footprint. If we fold the handle down, the mower can often be stored vertically or in a tighter space, freeing up room for other tools or equipment.

Low Maintenance Needs

Compared with gas mowers, maintenance is simple:

• No gas or oil changes
• No spark plugs or air filters to replace
• No carburetor issues

Our main responsibilities include:

• Keeping the underside of the deck reasonably clean
• Sharpening or replacing the blade periodically for a clean cut
• Storing the battery properly (avoid extreme temperatures, keep it dry)

This level of simplicity is a big part of the appeal for those of us who want reliable performance without frequent tinkering.

---

Warranty and Support

Greenworks backs this mower with a 3-year tool warranty and a 3-year battery warranty, which is a solid vote of confidence in both the mower and its power source.

3-Year Tool Warranty

A three-year warranty period for the mower itself reassures us that the manufacturer expects it to hold up under typical residential use. If we encounter defects or significant issues under normal operating conditions, we have recourse through Greenworks support during that time.

3-Year Battery Warranty

The inclusion of a 3-year battery warranty is especially important because batteries are often the most expensive single component to replace in a cordless system. Knowing that the battery is covered for three years gives us a more predictable ownership cost, at least for those early years.

We should always read the details of the warranty for exclusions, but on balance, this coverage is generous for a consumer-grade cordless mower.

Ideal Use Cases: Who Is This Mower For?

Not every mower is right for every yard. The Greenworks 40V 16″ mower is purpose-built for a certain type of user and yard, and it shines when matched with the right environment and expectations.

Best for Small to Medium Yards (Up to ½ Acre)

The mower is explicitly recommended for yards up to about half an acre. In practice:

• For smaller city or suburban lots, one fully charged 4.0Ah battery can often cover the entire yard.
• For larger half-acre properties, we may need to mow efficiently, maintain a regular schedule, or consider a second battery for uninterrupted work.

If we have a very large property or fields with extremely thick, tall, or tough vegetation, a larger deck or higher-powered mower may be more appropriate.

Great for Regular Maintenance, Not Overgrown Jungle

This mower does its best work when we mow on a consistent schedule. If we let grass grow excessively tall or wet, any small electric mower will understandably have to work harder.

It is ideal if:

• We mow weekly or at least every 10–14 days
• Our grass is typical residential turf rather than dense weeds and brush
• We are willing to adjust cutting height or make two passes if we have let the lawn get too tall

Used that way, the mower offers a smooth, predictable experience.

Pros and Cons

To decide whether this mower truly fits our needs, it helps to lay out the main advantages and the potential limitations in a clear way.

What We Will Probably Like

• Cordless convenience: No gas, no cords, and far fewer hassles with starting or maintenance.
• Lightweight and easy to push: Friendly for users of various ages and strengths, especially in smaller yards.
• Brushless motor: Delivers good torque, quieter operation, and better longevity than brushed motors.
• 2-in-1 versatility: Choice of mulching or rear bagging depending on our preference or season.
• Single-lever height adjustment: Quick and simple to tailor cutting height to yard conditions.
• 40V system compatibility: Battery works with 75+ other Greenworks tools for a unified yard-care setup.
• Decent runtime for smaller lawns: Up to 30 minutes on the included 4.0Ah battery suits many typical yards.
• Strong warranties: 3-year tool and 3-year battery coverage provide peace of mind.

What Might Be Limitations for Some of Us

• Not ideal for very large or heavily overgrown lawns: 16″ deck and 30-minute runtime are best suited to modest yard sizes and regular mowing habits.
• Push-only: No self-propel feature, so those with big hills or limited physical strength on larger yards may need to consider that.
• Runtime dependent on conditions: Thick, tall, or wet grass shortens the usable time per charge.
• Single battery included: If we expect to mow longer than 30 minutes regularly, a second battery becomes very desirable.

These trade-offs are normal for a lightweight cordless mower. What matters is whether our yard and our expectations align with what this mower is designed to do.

Comparing to Traditional Gas Mowers

If we have used gas mowers for years, switching to an electric cordless model like this one can feel like a significant change. Understanding the differences helps us judge whether the benefits outweigh the compromises for our situation.

Where This Cordless Mower Has an Edge

• Ease of starting: Push-button start is vastly simpler and more reliable than pulling a cord on a small gas engine.
• Lower noise: Less noise makes mowing more comfortable and considerate of neighbors.
• Lower maintenance: No oil changes, no spark plug replacements, no fuel stabilizers, and no carburetor cleanouts.
• No fuel storage: We can avoid the smell and safety concerns of keeping gasoline around.
• Lighter weight: Easier handling, especially for those of us who do not want to wrestle with heavy equipment.

Where Gas Mowers Still Have an Advantage

• Unlimited runtime (with fuel): We can refuel in minutes and keep going for very large properties.
• More raw power: Gas engines handle heavier growth, tall weeds, and wet grass with more authority.
• Larger deck options: Gas mowers often come in bigger deck sizes, reducing mowing time for large open areas.

For typical small to medium residential lawns, many of us may decide that the convenience and lower hassle of cordless electric outweigh the gas advantages, especially if we do not have extreme mowing conditions.

Practical Tips for Getting the Best Results

To get the most from the Greenworks 40V 16″ mower, a few simple habits can make a big difference in both performance and battery life.

Mow Under Favorable Conditions

• Try to mow when grass is dry, since wet grass can clump and make mulching or bagging less effective.
• Avoid letting the lawn become excessively tall; cutting off more than a third of the grass height in one pass puts extra strain on the motor and battery.

By staying on top of growth, we keep the mower working in its sweet spot and extend our usable runtime.

Maintain a Sharp Blade

A sharp blade:

• Cuts cleaner, leaving the lawn looking better
• Reduces strain on the motor and preserves battery energy
• Helps prevent tearing of grass blades, which can lead to a dull, brownish appearance

Checking and sharpening (or replacing) the blade periodically keeps performance high and our yard looking fresher.

Plan Our Mowing Pattern

If we have a medium-sized yard near the top of the mower’s recommended capacity, planning our route can help:

• Mow in efficient, overlapping passes to avoid covering the same ground repeatedly.
• Start with the more demanding or thicker areas while the battery is freshest.
• Use a higher cutting height if the grass is longer than usual, then gradually lower it in subsequent cuts.

These small strategies can add several effective minutes to our runtime.

Overall Value for Homeowners

When we weigh the price, performance, ease of use, and versatility, the Greenworks 40V 16″ Brushless Cordless (Push) Lawn Mower represents strong value for many homeowners with typical small to medium yards.

We are getting:

• A complete cordless kit (mower, 4.0Ah battery, charger, bag)
• A brushless motor with modern, efficient technology
• A battery system that can power a broader lineup of tools
• Multi-year warranties that protect both tool and battery

For those of us who are ready to step away from gas but do not want an oversized or overly complex machine, this mower sits in a comfortable “just right” zone.

---

Final Thoughts: Is This the Right Mower for Us?

In the end, our decision should come down to how well this mower aligns with our yard size, mowing habits, and priorities.

We will likely be happy with this mower if:

• Our yard is small to medium, roughly up to half an acre.
• We mow regularly, rather than letting grass grow excessively tall.
• We appreciate low noise, easy starting, and low maintenance.
• We like the idea of building a 40V tool ecosystem around a shared battery system.

We may want to consider other options if:

• We have a very large property or regularly face long, dense, or rough mowing sessions.
• We demand self-propel functionality for steep hills or very long mowing runs.

For many typical residential lawns, though, the Greenworks 40V 16″ Brushless Cordless (Push) Lawn Mower (4.0Ah Battery and Charger Included) offers a friendly, practical path into cordless mowing. It shifts the experience from noisy, high-maintenance gas equipment to a simpler, cleaner routine that fits more comfortably into our everyday lives.
