Greenworks 40V vs 80V — find out which cordless mower fits your yard best. Learn from real use, honest results, and simple tips before you buy.
Thank you for reading this post, don't forget to subscribe!If you’re choosing between the Greenworks 40V and 80V cordless mowers, it all comes down to your yard size and how much power you need. The 40V is ideal for small, suburban lawns. It’s light, quiet, and simple to use. The 80V brings extra strength for bigger yards or thick grass.
From my own use, the 40V felt smooth and easy to handle. The 80V, on the other hand, impressed me with its strong torque and long battery life. After using both for a full mowing season here in the U.S., I found that each one shines in its own way. In this guide, I’ll help you see which mower truly fits your yard and your lifestyle.
🌿 Is Greenworks 40V Good?
Yes — it’s a great choice for small and mid-sized yards.
I’ve been using the Greenworks 40V Lawn Mower, and I’m honestly impressed. It’s light, quiet, and needs no gas or oil. For someone who hasn’t mowed in years, I found it very easy to set up and use.
The mower runs on a 40V Lithium-Ion Battery, and mine came with a 4.0Ah pack. I mowed both my front and back yard — about one-third of an acre — on a single charge. That’s solid for a cordless mower. The Battery Management System (BMS) keeps the power steady, and the Interchangeable Battery Platform means I can use the same battery with my Leaf Blower and String Trimmer too.

⚙️ Setup and Use
Assembly took only a few minutes.
I lifted the handle, attached the Grass Catcher Bag, and slid in the battery.
It started with one button press and a quick lever pull — no pulling cords, no mixing fuel.
It also has a height adjustment lever, so I could change the cutting height to fit my lawn.
For most U.S. homeowners with small or medium lawns, the Greenworks 40V mower hits the right balance between price, performance, and convenience.
✅ What I Like
Lightweight and Easy to Use
The Greenworks 40V mower feels light compared to gas models. I can push it easily, even through thick grass. The cordless design makes mowing fast and simple — no cords or fuel smells.
Quiet and Eco-Friendly
It’s much quieter than gas mowers, which is great for early mornings. I also love that it runs with zero emissions — good for the planet and my lungs.
Cross-Tool Compatibility
One battery powers many tools.
The Greenworks 40V Platform supports 75+ tools, including mowers, blowers, and trimmers.
It’s cost-saving because I don’t need a new battery for each tool.
SmartCut™ Load Sensing System
This system adjusts power for thick or tall grass. It helps save battery and gives smooth, even cuts. I saw it work well on uneven lawn areas.
⚠️ What Could Be Better
Small Grass Catcher Bag
The bag fills up fast, especially with tall or wet grass. I had to stop and empty it a few times. A larger bag or mulching option would make mowing smoother.
Battery Runtime for Bigger Yards
The 4.0Ah battery worked fine for me, but large yards may need more. Having a second battery or a Dual Port Charger is a smart move.
Cutting Width
The 16-inch deck fits tight spaces but takes longer for big yards. A 20-inch or 21-inch model would be better for larger lawns.
🌱 Recommendation
If you want a light, easy-to-handle cordless mower for a small or medium yard, the Greenworks 40V Lawn Mower is a great buy.
It’s perfect for anyone who prefers battery-powered tools over gas ones.
If your yard is bigger than one-third of an acre or has thick grass, buy an extra battery or choose a larger cutting deck model.
The Greenworks 40V combo kits — mower, blower, and trimmer — offer strong value.
You can power them all with one battery. This makes expanding your tool collection easy and affordable.
Overall, my experience with the Greenworks 40V system has been positive.
It’s clean, quiet, and efficient — a perfect fit for today’s homeowner who wants simple, eco-friendly lawn care.
🌿 Is Greenworks 80V Good?
Yes — the Greenworks 80V mower is an excellent choice if you want a quiet, strong, and eco-friendly lawn mower.
I’ve used it through a full mowing season, and it’s been great on both dense fescue grass and light suburban lawns.
The brushless DigiPro motor gives steady power, and the SmartCut™ Load Sensing System boosts strength when the grass gets thick or damp.
What I liked most is how smooth the self-propelled drive feels.
It moves fast when needed and stays easy to control at slower speeds.
The steel deck feels solid and strong, while the LED headlights make mowing at dawn or dusk much easier — a nice touch during hot summer days.
The 80V lithium-ion battery is another win.
With a 4.0Ah pack, I got about 60 minutes of mowing using both bagging and mulching modes.
It recharges in under an hour with the rapid charger, and the same battery works with my 80V chainsaw and leaf blower — saving space, money, and time.

✅ What I Like
Powerful Like Gas
The 80V brushless motor gives gas-level power without the smell, mess, or noise.
It adjusts on its own for thick patches and never slows down.
It’s perfect for medium to large lawns with uneven grass height.
Quiet and Low Maintenance
There’s no oil, gas, or cord pulling.
You just press a button and start mowing.
It’s very quiet, so you can mow early on a Sunday without bothering neighbors.
Smart and Simple Design
The folding handle saves space in small garages.
The 3-in-1 deck lets you switch between mulching, bagging, or side discharge fast.
The magnetic battery door gives it a premium feel.
Interchangeable Battery Platform
You can use the same 80V battery for your blower, trimmer, and chainsaw.
It makes the whole Greenworks 80V system convenient and cost-effective.
Reliable Warranty and Support
Greenworks offers strong warranty service.
They’ve replaced parts for me quickly and without trouble.
That builds real trust for long-term use.
⚠️ What Could Be Better
Battery Cost
Extra or replacement 80V batteries can be pricey.
I wish Greenworks offered bundle deals or discounts for repeat buyers.
Heavier Than 40V Models
The steel deck adds durability but also weight.
It’s fine with self-propel mode, but manual pushing can be tiring in tight areas.
Grass Bag Size
The grass catcher bag fills fast when mowing tall or wet grass.
A slightly larger bag would make mowing smoother for big lawns.
🌱 Recommendation
If you’re upgrading from a 40V mower or switching from gas, the Greenworks 80V is a smart move.
It’s powerful, quiet, and easy to maintain.
I recommend it if:
- You want gas-like power without fumes or noise.
- You already own other Greenworks 80V tools.
- You need a mower that can handle tall or damp grass with ease.
If your yard is small, the 40V model is lighter and cheaper.
But for medium to large U.S. lawns, the 80V platform gives the best mix of power, runtime, and flexibility available today.
✅ Summary Snapshot
- Power: Equal to a 45cc gas engine
- Runtime: 60+ minutes with 4.0Ah battery
- Deck: 21″ steel, 3-in-1 cutting system
- Motor: Brushless DigiPro with SmartCut™ load sensing
- Noise: Very low
- Warranty: Strong U.S. support
In short — the Greenworks 80V mower delivers.
It’s efficient, durable, and quiet — the perfect cordless mower for modern homeowners who want power without pollution.
It feels like the future of lawn care — clean, strong, and built to last.
Greenworks 40V vs 80V – Easy Comparison Guide
I’ve used both the Greenworks 40V and 80V mowers for months. Each one has its strengths. The right one for you depends on your yard size and how often you mow. Let’s break it down in simple terms based on real use.
1. Cutting Power
The Greenworks 80V mower is stronger. It cuts thick, wet grass without slowing down. The SmartCut™ system adds more power when needed. It feels just as strong as a gas mower.
The Greenworks 40V mower is quieter and lighter. It works best for small or medium lawns. It can handle weekly mowing but may slow down in heavy grass.
My experience:
When cutting tall fescue, the 80V cut cleanly in one pass. The 40V needed two. For most suburban lawns, the 40V works fine.
⭐ Rating:
40V – 8/10
80V – 9.5/10
2. Battery Life
The 80V battery (4.0Ah) lasts about an hour per charge. The rapid charger refills it in 45 minutes.
The 40V battery (4.0Ah) runs for 35–40 minutes. That’s enough for small yards. Larger yards may need two batteries.
My experience:
For my ⅓-acre yard, one 80V battery finishes the job. The 40V needs a second one. I use both batteries in my trimmer and blower too.
