Greenworks 40V Cordless Lawn Mowers Models
Greenworks, a well-known brand of outdoor power tools, embodies these characteristics in their 40V cordless lawn mowers. The 16″ push and 21″ self-propelled mower types are two of their best-selling models. These devices are an attractive option for contemporary homes because they not only have the strength and efficiency to handle your yard labor, but they also have the convenience of cordless operation.
To be honest with you, our team wasn’t initially all that aware of the Greenworks brand. We didn’t know it was a leader in the market and that the Greenworks 40V Cordless Lawn Mowers are one of the top selling ones online. Turns out that Greenworks are actually quite proficient in making motors and mowers. After a bit of research, let us tell you something our fellow mower enthusiast… You’re guaranteed to find exactly what you need within Greenworks’ 16-inch Push and 21-inch Self-Propelled lawn mower models!
The 16-Inch (Push) Greenworks 40V Cordless Lawn Mower Brushless Model
Now first of all, let’s talk about the small design, the one that you will have to manually push around the yard. Don’t worry, there are a lot of pros for having a push mower.
Having a sturdy, functional lawn mower is essential to having a well-kept lawn. This is where the Greenworks 16″ Cordless (Push) Lawn Mower with 40V input fits in and is perfect for houses with ½ acre or smaller yards. With so many features and benefits, this electric lawn mower is a great choice for your lawn care needs. And let’s repeat again – “cordless”! At The Mowers Guide we just adore cordless mowers because of how easy it is for everyone, isn’t it!
If your yard has a lot of kinks and angles or trees to go around, this mower is a great option for your needs because of its elegant cordless design, which offers independence and ease! You can cut your lawn, all in one single go (session) with the help of a lasting 4.0Ah battery, which can operate for up to 45 minutes (fully charged). You can move around your yard without trouble or any restrictions now that you have this battery. Let us tell you, for a mower this quality, 45 minutes is quite a long while for mowing.
Now a few bullet points to outline the main characteristic of the Greenworks mower:
- Brushless Motor
- Cutting Width: 10–16 inches
- Cutting Deck Material: Durable Plastic
- Height Adjustment: 5-position, single lever
- Cutting Height Range: 1-1/4″ to 3-3/8″
- 2-in-1 Feature: Mulching and rear bagging options
- Battery Runtime: Up to 45 minutes
- Battery Charging Time: 120 minutes. It may seem long but don’t confuse this with a phone battery. The mower battery is designed to have a long life. The charging is also made to preserve the battery life of the mower.
- Included Accessories: grass collection bag, charger, manual
- Warranty: 3 years (tool and battery). This one is amazing and is a bang for your buck. But bear in mind we got this one from Amazon so make sure that whichever vendor you’re buying the mower from offers the warranty.
Undeniable Powers
These are the things we most enjoyed in these two mowers: Greenworks Push 16-inch and the Automatic Greenworks 21-inch Self-propelled.
Accurate Cutting Power
Both, the 16-inch (Push) Greenworks 40V and the 21-inch (Self-propelled) Greenworks 40V Cordless Lawn Mowers utilize a brushless motor which helps them provide efficient cutting power without the need for maintenance. This motor makes it easy to manage even the roughest grass conditions and ensures a constant, clean, and accurate cut.
Adaptability to Any Environment
With its single lever that allows for five various height adjustments, this battery-operated lawn mower is ideal for a multitude of applications. To achieve the finest results, you may easily modify the cutting height, regardless of whether your lawn is well-manicured or has thick, tall grass. You can configure the mower to meet your unique requirements by choosing from a variety of cutting heights, ranging from 1-1/4″ to 3-3/8″.
Dual-Use Capabilities
The Greenworks 40V 16″ Cordless Lawn Mower is unique among lawn mowers due to its dual use. With the options this feature provides for mulching and rear bagging, you can dispose of your grass clippings any way you see fit. Rear bagging makes disposal simple, and mulching returns grass clippings as nutrients to your lawn. This adaptability guarantees that you can keep your grass neat and healthy, following your preferences. However, we think that the Greenworks 21″ one will do a better job at this because of the wider blades and the wider area of clipping disposal.
You will also need one of these to remove any sticky grass clipping from your blades:
- Vibrations Grass Hawk Ultimate Mower Blade Cleaning Tool
- Long Handle Lawnmower Deck Scraper – 18 inches Long
The 21-inch (Self-Propelled) Greenworks 40V Cordless Lawn Mower Brushless Model
The ideal option for people with larger lawns or who just want to make mowing as simple as possible is the 21″ self-propelled mower. With very little physical effort from you, this mower moves forward on its own, relieving the strain of mowing. With its broader 21″ cutting deck, you can mow a larger area in less time, and the rechargeable lithium battery inside a Greenworks cordless electric mower is what powers the mower.
The 40-volt battery guarantees steady performance all through your mow. Brushless motor technology, which offers greater torque, quieter operation, and longer life, is featured in this eco-friendly equipment.
Here are the general characteristics:
- Brushless Motor
- Deck size: 21”
- What’s Included: One (1) 40V Battery and Charger
- Runtime: Up to 45 minutes with an included 5.0 Ah battery
- Charge Time: 150 minutes with an included 5.0 Ah battery
- Acreage: Up to 1/2 Acre
- Powers 75+ Tools with any Greenworks 40V Battery (*40V 8Ah battery can’t fit with this mower). We’d love it to have a huge battery but this design only fits its original battery, you won’t be able to fit in a bigger one.
Effortless Operation
You can handle even the most difficult yards by yourself, as this model will never stall. Greenworks sensors send a command to its brushless motor to send more power to the mower blades when the grass becomes thick, tall, or wet. The outcome is always the same: flawless grass, even clipping height, neat and perfect lawn.
Powerful and Enduring
With its heavy-duty steel construction, the deck is prepared to face any obstacle. To achieve unparalleled blade speed, the design of the Greenworks brushless motor is quite a good piece of engineering. We tried comparing it to bigger brands and it seems really sturdy whilst also being manoeuvrable during tests.
Some people who have it even say that after 3 years of usage, the mower hasn’t even began to feel like having any amortization. Boom!
Customer Testimonial:
“This mower is still operating at an excellent level. It took some effort at first to remove the mower’s batteries, but after pressing down on a release button a few times, it became less difficult. In addition, I discovered yesterday that my electric pressure washer is also Greenworks after completing some spring cleaning. It has survived through hours of nonstop use and has never given me any problems in the five years that I’ve owned it. I believe it’s fair to state that I’m pleased with Greenworks’ product quality.”

Blades of Quality
The blades are high quality razor-edged steel. Easy to maintain, you don’t have to always buy new ones. We’ve seen some advice online on how to sharpen them but bear in mind that it’s not completely safe. And if you do plan to sharpen them, ALWAYS take out the battery, test to power it on, and only then attempt to safely disassemble the blades from the mower for maintenance.
Striking Performance, Every Cut
With its brushless motor, it delivers gas-like power with minimal noise and pollutants, making it a powerful tool. The 21-inch cutting deck is ideal for medium- to large-sized lawns since it allows you to mow more territory in less time. Additionally, you can easily alter the appearance of your grass with customizable cutting heights. The cutting motion is designed to have several settings, so you’re not actually stuck with one mode of lawn mowing.
A Breeze to Use
Easy to begin with only a button push. It doesn’t require any exertion to mow because it is self-propelled! Silent mowing means it’s easy on the ears. It’s easy to store in compact areas, and if desired, you may hang it up. With the handy 3-in-1 cutting deck, you may select between side discharge, bagging, or mulching your cut finish.
Eco-Friendly with Minimal Upkeep
Not only will this Greenworks mower make your life easier, but it will also benefit Mother Nature. No more trips to the gas station, spark plug replacements, or oil changes. You only need to fully charge the battery to get going. In addition, by being quiet throughout your early morning mowing operations, you’ll become the hero of the neighborhood.
Recall that you get the same low-maintenance, environmentally friendly features that Greenworks 40V cordless lawn mowers are renowned for, regardless of the size you select.
Customer Testimonial:
“In my 50 years of mowing, this mower is the best I have ever used. I’m 66 years old now and a little disabled, so I can’t push a mower around the yard or start a gas mower. It’s a delight to use, and this self-propelled mower takes care of both those problems. As with any battery-powered gadget, its sole shortcoming is its battery life.
In addition to the four Green Works product batteries I already had, this mower also included a five-amp-hour battery. Thus, I have enough power to mow an entire acre of grass with all five batteries. It has more than enough power for typical mowing. Probably not enough for wet grass that is several feet long, but adequate for regular mowing.
It’s whisper-quiet, gas-free, and exhaust-free. I adore it and heartily suggest it to everyone. It also requires no tools for assembly; all you need to do is attach the handle and charge the battery to get going. I get 20 to 30 minutes out of the 5-amp-hour battery that comes with it. If I had that much stamina, which I don’t, I could mow consistently for about two hours with my four extra batteries. Fantastic mower.”

Top Tips to Keep Your Greenworks 40V Cordless Lawn Mower in Peak Condition
Do you want your Greenworks mower to last as long as possible? You’ve arrived at the right place!
You do have 10-14 days in general between each lawn cutting sessions as that’s what we explore to be the healthy recovery period for your grass. We recommend you use that period to find some time for some care and maintenance of your Greenworks 40V cordless lawn mower.
Let us explore some simple upkeep strategies that will ensure your grass remains immaculate throughout the entire season.
Sparkling Clean for Superior Performance
After each mow, give your Greenworks a quick once-over. Brush off grass clippings and debris from the deck and wheels. This simple habit prevents buildup that can affect performance.
Pro tip: use a plastic scraper for stubborn gunk; metal tools with any Greenworks 40V battery might scratch the surface. Here are some options:
Sharp Blades, Sharp Lawns
Sharp blades mean a healthier lawn. Every few months, or when you notice ragged grass tips, it’s time for a blade check. Examine it carefully after removing the blade (remember to disconnect the battery first!). Replace it or sharpen it yourself if it’s dull or broken. Your grass will thank you!

Pro tip: Some blades are sold unsharpened for safety reasons. If you buy an unsharpened blade, you may want to buy a blade sharepener. These are a few options:
- SHARPAL 103N Knife Garden Tool Multi-Sharpener – no tools needed, fully manual
- Double-Layer Grindstone Mower Blade Sharpener for Any Power Drill (you need a hand drill for this one)
Battery TLC
Your Greenworks’ heart is its battery. Gone are the days where you have to worry about how much gas will your new lawn mower use. Store it in a cool, dry place when not in use. Avoid extreme temperatures—no leaving it in your hot garage!
Before winter, give it a full charge, and top it up every few months during storage. This keeps the battery happy and ready for spring. We at The Mowers Guide aren’t battery physicists, but our experience has shown us how to take care of our batteries to make them last longer.
Our water resistance tests passed without any problems, but a few minutes hose water is nothing compared to leaving the mower out in the rain. You’re probably wondering whether any lawn mower is safe to be left in the rain. As durable as it may be, we recommend you not to leave the Greenworks 40V cordless lawn mowers outside in the rain, its a machine after all and its internals can develop rust or get damaged electrics.
In case you do want to replace your battery or just get a spare one, we’ve got you covered!
Yearly Tune-Up for Top Performance
Give your mower a thorough inspection once a year. Check for wear and tear, lubricate moving parts, and tighten any loose bolts. Like a day at the spa for your Greenworks! Most garden centers offer tune-up services if you’re not comfortable doing this yourself.
Recall that a little love does wonders. Your Greenworks mower will be your lawn’s closest friend for many years if you follow these easy steps!
