I used to own a loud gas mower. It was heavy, smelly, and hard to start. Every time I pulled the cord, I braced myself. It felt like a workout before the mowing even began.
My lawn isn’t huge. It’s about a quarter-acre with some thick patches. I needed something lighter and easier. That’s when I found the Greenworks 40V lawn mower 16-inch.
I liked that it was cordless, clean, and quiet. The size was right too—not too big, not too small. I looked at the Greenworks 40V lawn mower 20-inch, but it felt like more than I needed.
Plus, I wanted a mower I could lift and store without a hassle. This one checked the boxes. The fact that I could use the same battery for other tools? That sealed the deal.
Why I Chose the Greenworks 40V 16-Inch Mower
I used to own a gas mower. It was loud, heavy, and hard to start. I dreaded using it every week. Pulling the cord felt like arm day at the gym.
My yard isn’t huge. It’s under a quarter-acre, with some thick grass in spots. I needed a mower that was light and easy to push, but still strong enough to get the job done.
The Greenworks 40V lawn mower 16-inch stood out. It’s cordless and clean. I liked that it was small, but still had power. I also looked at the Greenworks 40V lawn mower 20-inch, but it felt too big for my space.
One big plus? I already had a Greenworks 40V battery for my blower. That meant I didn’t need to buy extra gear. If you’re wondering if the 16-inch mower can handle real grass—the answer is yes, it does just fine.
First Impressions & Setup Experience
When the box arrived, I was a bit surprised by how light it felt. Honestly, I expected it to be heavier. Opening it up was simple. Everything was packed neatly, and nothing was rattling around. It took me less than ten minutes to get it out and set it up.
The assembly was almost too easy. No tools needed, no headache. I just snapped the handle into place, locked it in, and I was ready to go. The battery came about half-charged, so I plugged it in while I finished the setup. By the time I was done, the battery was nearly full.
The first thing I noticed was the size. It’s compact but not flimsy. The build feels solid, and the mower looks sharp in that bright green. It’s light enough for me to lift with one hand if I need to. That’s a huge plus, especially if you’re used to dragging around a bulky gas mower.
Now, about the design. The 16-inch cutting deck is a sweet spot for smaller yards like mine. It’s easy to maneuver, even around trees and flower beds. I did compare it to the Greenworks 40V lawn mower 20-inch before buying. The 20-inch model does cover more ground, but it’s also a bit heavier and bulkier. For my yard size, the 16-inch just made more sense. I didn’t want to wrestle with a mower every weekend.
If you’ve got a small to mid-sized yard, this one feels just right. You can tuck it away in the garage without it eating up space. And since it’s so light, moving it around is a breeze. Right from the start, it felt like the right choice.
Performance Breakdown – What It’s Like to Use It
Cutting ability on different grass lengths
I’ll be honest—this little mower surprised me. I’ve got a mix of grass in my yard. Some areas are thin and easy, but there are patches that grow thick and fast, especially after rain. The Greenworks 40V 16-inch handled both. On shorter grass, it just glides. Smooth and clean cuts, no bogging down. When I let the grass grow longer (I’ll admit, I skipped a week), it still managed well. I did have to slow my pace a bit, but it powered through without quitting. Pro tip: if your grass is jungle-thick, raise the deck height. It’ll cut cleaner without stressing the motor.
Mowing time and ease of pushing
With my quarter-acre yard, I get about 30 to 35 minutes of mowing time on a full charge with the 4.0Ah battery. That’s enough to finish my lawn in one go, unless I’m feeling extra picky and go over spots twice. As for pushing it? Honestly, it feels like I’m just walking. The mower is light and easy to push, even uphill. Compared to my old gas mower, it’s like night and day. No resistance, no heavy heaving. Even my teenage daughter gave it a try and didn’t complain!
Bagging and mulching functions
This mower gives you both bagging and mulching options, which is a win. I like to mulch most of the time since it feeds the lawn naturally. The clippings are pretty fine, too—it doesn’t leave messy clumps behind. When I do bag, the grass catcher is easy to attach and remove. It fills up quicker than a bigger mower, sure, but that’s expected with a 16-inch deck. Swapping between modes is super simple, no tools needed. It’s really just a matter of preference.
Maneuverability and turning radius
This is where the mower shines. Tight spaces, around trees, flower beds—you name it, it handles it. I’ve got a few garden beds with awkward curves, and this mower weaves around them without a fuss. The turning radius is tight enough that I don’t feel like I’m doing a 10-point turn every time. It’s honestly a joy to use in small or tricky spaces. Plus, since it’s so lightweight, backing up or pivoting feels effortless.

Battery Life & Charging Time
Real-life mowing test with the Greenworks 40V 4.0Ah battery
Let’s talk about the battery — because let’s be honest, that’s what most people worry about with cordless mowers.
For this review, I used the Greenworks 40V 4.0Ah battery. It came with my mower. My yard is just under a quarter-acre. Some spots are easy to mow. Others are thick and stubborn.
On a full charge, I can mow my whole lawn in 30 to 35 minutes. That’s mowing at a normal speed — not rushing but not super slow either. If I go over spots twice or really take my time, I get closer to 30 minutes. But for a regular mow? I always finish before the battery runs out.
One of my favorite features? There’s a battery gauge right on the handle. It has four little green lights. You can check your battery mid-mow with a quick glance. Super helpful when you’re thinking, “Uh-oh… am I gonna make it?”
How long does a 40V lawn mower battery last?
With the 4.0Ah battery, you can expect 30 to 45 minutes per charge. It really depends on a few things:
- How tall and thick your grass is
- How fast you mow
- If you’re bagging or mulching (bagging uses a little more power)
- If your yard is flat or hilly
In my case, I usually get 30 to 35 minutes per charge. That’s plenty for a small to medium-sized yard like mine.
Wondering about battery lifespan? Greenworks says the battery should last about 1,000 charge cycles if you take good care of it. That means:
- Store it inside (not in a hot garage)
- Don’t let it drain to 0% every time
- Don’t leave it on the charger forever
Charging Time & Battery Tips
Charging the 4.0Ah battery from empty to full takes about 1 hour and 30 minutes. I use the standard Greenworks charger that came in the box. That’s pretty quick. I usually mow, pop it on the charger, and it’s ready to go long before I need it again.
Pro tip: Got a bigger yard? Grab a second battery. That way you can mow nonstop without waiting.
The charger is simple to use. The lights blink while charging. When it’s done, the lights turn solid green. Easy!

40V vs. 80V – Is Higher Voltage Worth It?
Let’s break it down. The 80V mower has more power. It cuts thick grass fast. It’s great for big lawns or if you mow less often. The motor feels strong. It keeps going even when the grass gets tall.
But do you need all that power? Not always. I don’t. My 40V mower does the job just fine. I mow once a week. My yard is under a quarter-acre. It’s mostly flat. For me, the 40V is enough.
The 40V mower is light. It’s easy to push. It turns well and fits tight spots. I can carry it with one hand. The 80V is bigger. It’s heavy and takes more space in the shed. You feel the weight when turning or lifting it.
So, which should you choose?
Go with the 40V if your yard is small or flat. It’s simple, quiet, and light. You won’t need breaks or backup batteries.
Pick the 80V if your yard is large or wild. It has the power to cut thick, tall grass fast. You won’t slow down or need to recharge as often.
From what I’ve seen, more volts don’t always mean better. It’s like buying boots. You don’t get hiking boots for a walk in the park. You pick what fits your path.
Noise, Maintenance & Storage
Let’s start with the sound.
This mower is quiet. I checked with a phone app, and it read about 70 decibels. That’s like a vacuum or someone talking. My old gas mower? It roared at over 90 decibels. I had to wear earplugs and yell to talk.
So yes, the Greenworks 40V is much quieter than gas.
You can mow without bothering the neighbors. You can even hear birds while you work. It’s a small thing, but it makes mowing feel calm.
Now let’s talk about upkeep.
There’s hardly any. No gas, oil, or spark plugs. I don’t even need tools. I just clean the deck after mowing. I use a brush or my hand to wipe off grass.
This mower needs little to no maintenance.
I check the blade once in a while. I might sharpen it once a season. That’s about it. It’s simple. If you’ve owned a gas mower, this feels like a break.
Storage is just as easy.
The handle folds in seconds. You can stand the mower straight up to save room. I keep mine between a shelf and my blower. It fits like a book on a shelf.
The mower stores upright and saves floor space.
It’s also light. I can carry it with one hand if I need to move it. No heavy lifting or awkward turns. Just pick it up and go.
Bottom line: This mower is quiet, easy to care for, and saves space. If you want less noise and no gas mess, it’s a solid pick.
The Greenworks Ecosystem: Why It Matters
One reason I bought this mower? I already had a Greenworks battery. I used it with my blower. When I saw the mower used the same one, it was an easy choice.
Does the Greenworks 40V battery work with other tools?
Yes. It fits many Greenworks tools. You can use it with a blower, trimmer, or even a hedge cutter.
That’s what I love. One battery. Many tools. No need to buy more chargers. No need to learn how to use each one. Just plug it in and go.
First, I had the blower. Then came the mower. After that, I got the trimmer. Each tool worked with the same battery. It saved me money. And time. No cords. No gas. Just grab the battery and get to work.
The battery also charges fast. It lasts long enough for my yard. When it runs low, I pop in a spare. No waiting.
Why does the Greenworks system matter?
It makes yard work simple. You build a set of tools that all work together. You don’t waste money on extras. And you don’t have to store five chargers.
If you’re asking, “Should I stick with Greenworks?”—I say yes. Once you start, it’s smart to keep going. It all works as one team. And that makes yard work way easier.

Who Makes Greenworks? A Quick Look
Ever wonder who makes Greenworks? I did too. Before I bought my mower, I wanted to know who was behind the brand.
Greenworks is made by a company called Globe Tools Group. They started in 2002. The company is based in China, but they also have an office in North Carolina.
They build their own tools. That includes the mower, the battery, and the charger. It’s all made to work together. I like that. It feels more solid and less like a mix of random parts.
I called their support once. I had a question about the battery. A real person picked up. No long wait. No robot voices. The rep answered my question fast. That made me feel good about the brand.
If you’re asking, “Is Greenworks a good company?”—I think so. They’ve been around for a while. Their tools work well. And their support team is easy to reach.
So yes, the mower is good. But the company behind it? That matters too. And Greenworks checks out.
Pros & Cons of the Greenworks 40V 16-Inch Mower
Let’s keep it simple. Here’s what I liked—and what made me pause—after using this mower at home.
✅ Pros
It’s quiet.
No loud roar. I could still hear the birds. I didn’t need earplugs. It’s a calm way to mow.
It’s light.
This mower is easy to push. It feels smooth. My teen even gave it a try. No fuss, no fight.
No gas. No smell.
No fumes. No mess. No gas cans to store. It’s a clean way to mow.
Great for small yards.
The size is just right. It fits through gates and around trees. It also stores easy in the shed.
One battery, many tools.
I use the same battery for my trimmer and blower. It saves time and space.
❌ Cons
Short run time.
It runs for about 30 minutes. That works for my yard. But big lawns? You may need a backup battery.
Small deck = more passes.
It cuts a 16-inch path. That’s fine for small yards. But if your lawn is wide, it may take longer.
Thick grass slows it down.
If I skip a week, the mower works harder. I raise the deck, and it helps. But tall grass takes more time.
Bottom line?
This mower is great for small lawns. It’s light, clean, and easy to store. It won’t shake your arms or blast your ears.
But if you have a big yard? Or lots of tall grass? You may want a larger model.
It’s like a small bike. Great for short rides. But not built for long trips.
Comparing Cordless vs. Corded Greenworks Options
Greenworks 16-Inch Corded vs. 40V Cordless
Before I bought my cordless mower, I seriously considered the corded version. I mean, they look almost identical. Same size. Same brand. But there’s one big difference—the cord. And yeah, it makes a big impact on how you mow.
So if you’re stuck between the Greenworks 16-inch corded and the 40V cordless, here’s what I found.
I Tried a Corded Mower Once…
A few years back, my neighbor let me borrow her corded mower. It was one of those “I’ll be done in 10 minutes” kind of things, so I didn’t think twice.
But let me tell you—mowing with a cord is like vacuuming your lawn. Except the cord gets caught on everything. I kept having to stop, yank the cord loose, reposition it, and avoid mowing over it. At one point, I had it wrapped around a tree, and I just stood there laughing because… what else do you do?
Pros of the Corded Model
Now, don’t get me wrong. The Greenworks 16-inch corded lawn mower has its perks:
- It’s cheaper. You’ll save a good chunk of money upfront.
- Unlimited run time. As long as it’s plugged in, you’re good to go—no worrying about battery life.
- Lighter than cordless. Without the battery, it’s even easier to push.
- No charging needed. Just plug and mow.
If your yard is tiny, super flat, and close to the house—or if you’re on a tight budget—it might be worth considering.
Why I Chose Cordless
But for me? Cordless was the way to go. I didn’t want to babysit a cord the whole time. I like being able to walk around freely, take wide turns, and not stress about tangles.
The 40V cordless model gives me that freedom. I just pop in the battery, hit the button, and I’m mowing in seconds. No gas, no cord, no problem.
It’s also great if you have:
- Trees, garden beds, or anything the cord could snag on
- A yard that’s not right next to an outlet
- Pets or kids who love to run around (cords and chaos don’t mix)
So… Which One’s Better?
It honestly comes down to how you mow and where you live.
If you’ve got a small patch of grass and don’t mind dragging a cord around? The corded 16-inch mower can save you money and never runs out of juice.
But if you value freedom, have some obstacles in your yard, or just hate cords like I do? The 40V cordless is 100% worth it.
My Recommendation?
Go corded only if your yard is tiny, flat, and super open.
Otherwise, spend a little more and get the cordless. You’ll thank yourself every time you mow without tripping over an extension cable.
Honestly, it’s like the difference between wired headphones and wireless earbuds. Both work—but one makes life a lot easier.
Buyer’s Guide: Is the Greenworks 40V 16″ Lawn Mower Right for You?
Not sure if this mower is a good fit? Let’s break it down. Here’s what to know before you buy.
1. Best for Small Yards
This mower is great for yards under 1/4 acre. That’s about the size of a baseball field. The small deck helps you turn around trees and flower beds with ease.
👉 Tip: If you have a big yard, look at the 20-inch or 80V models. They cover more ground.
2. Works Best on Normal Grass
This mower cuts fine if you mow often. Thick or fast-growing grass may slow it down.
💬 “If I wait too long to mow, it struggles. But if I mow each week, it’s smooth.”
3. Battery Life Is Just Right
You’ll get about 45–50 minutes on a full charge. That’s enough for most small yards.
🔋 Charge time: About 2 hours.
Already have a Greenworks tool? You can use the same battery!
4. Easy to Store
Short on space? This mower folds up and stands on end. It weighs about 37 pounds, so it’s light too.
🧠 Good match: Use it with other 40V tools like a trimmer or blower.
5. Super Quiet
It’s much quieter than gas mowers. Mow early without waking the neighbors!
When This Mower Might Not Work for You
- Big yards: You’ll need a larger deck and more battery life. Try the 21″ or 80V.
- Tough jobs: Tall or thick grass may need a stronger mower.
- Don’t like charging: Gas may be better if you want to mow nonstop.
Final Verdict – Would I Recommend It?
Yes, I would. If you have a small yard, this mower is a great pick. It’s light, easy to use, and quiet. No gas. No pull cords. Just push a button and go.
For me, mowing has gone from a chore to a breeze. I can cut my grass in 25 minutes with one charge. That’s how long a Greenworks 40V lawn mower lasts for most small yards. The bag works well, and I like the clean cut it leaves behind.
If your yard is big or the grass gets thick, this may not be enough. In that case, I’d look at the 60V or 80V models. They give you more power and more time. That’s better for large or steep lawns.
Still, for most folks with smaller spaces, the 40V is all you need. It fits in tight spots and stores upright in the garage. I even use the same battery for my blower and trimmer. That’s what I love about Greenworks—it all works together.
If you want a mower that’s light, green, and gets the job done, this is it.

FAQs – Quick Answers for Curious Buyers
How long does a Greenworks 40V lawn mower run on one charge?
With the 4.0Ah battery, I get about 25 to 30 minutes. That’s enough to mow my small yard without stopping. Thick or wet grass can shorten the time a bit. Light grass? It lasts longer than you’d think.
Is a 16-inch deck big enough for my yard?
Yes—if your yard is under ¼ acre. The small deck is great for tight spots. It fits through gates and narrow paths. For big, open lawns, a wider deck may save time.
Can I use other Greenworks batteries with this mower?
Yes! All 40V Greenworks batteries work. I use the same one for my blower and mower. It’s a smart way to save money and space.
Where can I buy a new battery?
Check Greenworks’ site, Amazon, or stores like Lowe’s. I grabbed an extra during a sale. It’s good to have a backup if your yard needs more time.
What’s the warranty on the 40V mower?
The mower has a 3-year tool warranty. The battery has 2 years. I used support once—they were fast and helpful. Just keep your receipt and register online.
Greenworks 60V vs 40V – should I upgrade?
Got a big yard? The 60V is stronger and lasts longer. I tested both. The 40V is lighter and easier to use for small lawns. It’s perfect if you don’t need extra power.
Can I mulch with this mower?
Yes. It has a built-in mulching plug. I switch between bagging and mulching. The mulch is fine and breaks down fast. It helps feed the lawn, too.
Bonus Tip – Considering the Greenworks 60V 21” Self-Propelled Mower?
I tested the Greenworks 60V 21” Self-Propelled Mower, and it felt like a big step up. The power boost is real. It cuts fast and smooth, even in thick grass.
The self-propelled feature is my favorite part. It feels like the mower is doing the work for you. You just walk behind and guide it. On my sloped yard, that made a big difference. My arms and legs didn’t feel tired after mowing.
The 21-inch deck is wider, so you cover more ground in less time. That’s great if your lawn is big. The handles feel strong, and the LED lights are a nice touch. You can mow early or late without losing sight of the lines.
If you have a yard that’s over ¼ acre, the 60V is worth it. It runs longer, cuts faster, and is easier to push. It also looks and feels more solid than the 40V. But if your lawn is small, the 40V still gets the job done—and it’s lighter too.So, should you upgrade to the Greenworks 60V 21” mower? Yes, if you want more power and a smoother push. I’d pick it for medium to large lawns. It makes mowing feel less like a chore—and more like a quick walk in the yard.
