WORX Nitro Mower Review: Game-Changing Lawn Care for Any Yard
First Impressions
Have you ever dreaded yard work so much that you considered paving your entire lawn? I’ve been there! After wrestling with a gas guzzler for years, I decided enough was enough. Enter the WORX Nitro 40V 21″ Cordless Lawn Mower.
My first impression upon unboxing? This thing looks and feels solid. The packaging was well-organized, and the mower itself has a sturdy, premium feel. No cheap plastic here! It’s clear that WORX put some thought into the design.
What really blew me away was how much quieter and easier mowing became. No more yanking cords or choking on fumes! The Aerodeck design also seems to make a difference in the quality of the cut. Keep reading for my deep dive into how the WORX Nitro transformed my weekends.
Key Features & Specifications
Okay, here is the features section, written from the perspective of someone who’s used the WORX Nitro 40V 21″ Cordless Lawn Mower:
Aerodeck Technology: Cut Quality and Collection
The WORX Nitro 40V 21″ Cordless Lawn Mower boasts Aerodeck technology, and after several weeks of using it, I can attest it’s more than just a fancy name. Essentially, the deck is vented in a way that creates a stronger lift, preventing clogs and clumps while maximizing airflow. This not only contributes to a cleaner, more even cut, but it also dramatically improves how well the mower bags clippings.
I was honestly surprised. My old mower would constantly leave clumps behind, especially when the grass was even slightly damp. With the WORX Nitro, I’ve noticed a significant reduction in those unsightly clumps, and the grass clippings are packed much more tightly into the collection bag. This means fewer trips to empty the bag, which saves time and makes mowing a less tedious chore. I would say I have reduced the amount of trips to empty by about 20-25% compared to my old mower.
Brushless Motor 2.0: Power and Runtime
The Brushless Motor 2.0 is what really sets this mower apart. WORX claims it delivers 40% more power and 10% longer runtime than their first-generation brushless motors. Having used several cordless mowers in the past, I can say this feels noticeably more robust, and it definitely runs longer on a single charge.
What I love is how this added power translates into real-world performance. I have a section of my lawn that always gives my mowers trouble – it’s thick, St. Augustine grass that tends to bog things down. The WORX Nitro 40V 21″ Cordless Lawn Mower powered through it with ease, without any noticeable drop in speed or cutting performance. The included (2) 20V 5.0Ah PowerShare Pro batteries, are great for this mower, and I can now do my whole lawn without stopping to recharge.
Intellicut Technology: Smart Mowing
The Intellicut technology on the WORX Nitro 40V 21″ Cordless Lawn Mower is a game-changer in terms of convenience and efficiency. Using patented sensors, the mower automatically adjusts its cutting speed based on the density of the grass. When you hit a patch of thick grass, the motor revs up to provide more power; when you’re mowing thinner areas, it dials back to conserve battery life.
I found this feature particularly useful when transitioning between different sections of my yard, from the thick, shaded areas under my trees to the sun-drenched, thinner grass in the open. You can actually hear the motor adjusting, and I’ve definitely noticed an improvement in battery life since using the Intellicut feature. This means I can tackle my entire lawn on a single charge, worry-free.
3-in-1 Functionality: Mulch, Bag, and Discharge
Versatility is key, and the WORX Nitro 40V 21″ Cordless Lawn Mower offers three different mowing options: mulching, bagging, and rear side-discharging. Switching between these modes is quick and easy, thanks to the included mulch plug and discharge chute.
I personally prefer mulching, as it returns nutrients to the soil and helps keep my lawn healthy. The mulch plug is easy to install and remove, and I’ve been impressed with how finely the mower chops up the grass clippings for mulching. However, the bagging option is also excellent for collecting leaves and other debris, and the rear side-discharge is useful for longer grass that you don’t want to mulch or bag.
🧑🌾 Who Should Buy This: WORX Nitro 40V 21″ Cordless Lawn Mower
After spending a good chunk of the summer pushing, trimming, and testing this mower through everything from freshly sprouted spring grass to thick mid-summer patches, I’ve got a clear picture of who this tool is really made for.
This isn’t just another cordless mower—it’s a smart upgrade for folks who want power and convenience without the hassle of gas. If any of these sound like you, the WORX Nitro 40V might be exactly what you’ve been looking for.
✅ Ideal Buyers:
👨🌾 Homeowners with Small to Medium Yards
If your lawn is under about a third of an acre, this mower covers all the bases. The 21-inch deck cuts efficiently, and the battery lasts long enough to get the job done—especially if you’re maintaining rather than tackling overgrown terrain.
🔌 Anyone Done with Gas Mowers
If you’re tired of mixing fuel, dealing with pull cords, or storing gas, this is a breath of fresh air. Push-button start, no emissions, no oil changes—just charge and go. It’s a major relief for anyone who wants mowing to feel less like a chore.
🌱 Eco-Conscious Gardeners
No gas, no fumes, no pollution—this mower checks all the boxes for green-minded homeowners. It runs cleanly and quietly, making it perfect for those who care about sustainability and neighbor relations.
🏘️ Urban & Suburban Residents
Living in a neighborhood where noise and space matter? The Nitro is impressively quiet compared to gas mowers, and its compact size makes it easy to store in small garages, sheds, or even on a balcony.
🧓 Older Adults or Those Seeking Low-Effort Mowing
Thanks to its self-propelled feature (on select models), lightweight build, and simple operation, it’s ideal for anyone who finds traditional mowers too heavy or physically demanding.
💡 First-Time Electric Mower Users
If you’re stepping into the world of cordless tools for the first time, this is a great entry point. It offers solid performance without overwhelming complexity—plus, it pairs well with other WORX 40V tools.
🛠️ DIYers & Weekend Warriors
Whether you’re maintaining your own lawn or doing light landscaping for friends and family, this mower gives you reliable, consistent performance without the maintenance headaches of gas equipment.
🚫 Not the Best Fit For:
- Large Property Owners : If you have more than half an acre, you’ll likely find the battery life limiting—even with two batteries, it can require frequent swaps.
- Heavy-Duty Landscapers : While durable for homeowner use, it’s not built for daily professional use or commercial-grade demands.
- Users Looking for Ultra-Fast Recharge Times : Charging takes around 60–90 minutes, which may slow things down if you need back-to-back use.
- Those Who Need Mulching Functionality : Depending on the model, it may only offer rear bagging and side discharge—no mulching option.
🏡 Final Thoughts
The WORX Nitro 40V 21″ Cordless Lawn Mower is a fantastic fit for homeowners who want a clean, quiet, and convenient way to maintain their lawn. It shines brightest for small to medium yards and users who value simplicity, eco-friendliness, and modern convenience over raw horsepower.
If you’re ready to ditch the gas and simplify your lawn care routine—without sacrificing too much power—this one’s definitely worth serious consideration.
Who Might NOT Benefit?
While I’m a big fan of the WORX Nitro 40V 21″ Cordless Lawn Mower, it’s not a one-size-fits-all solution. If you have a massive property – think multi-acre estate – or if you’re dealing with extremely thick, overgrown grass on a regular basis, you might need a more powerful, heavy-duty mower. I found that, for most residential lawns, it provides more than enough power, but it may not be the best option for extreme conditions.
Pros & Cons
Okay, here’s my honest take on the WORX Nitro 40V 21″ Cordless Lawn Mower, after putting it through its paces in my rather unruly backyard.
Pros:
- Aerodeck Cuts Well: The Aerodeck design really does prevent clumping, even in damp grass. I noticed fewer missed blades and a cleaner cut compared to my old mower, which would often leave clumps behind, especially after a rain.
- Brushless Powerhouse: The Brushless motor 2.0 delivered serious power; tackling thick patches of weeds was no problem. It felt noticeably stronger than my neighbor’s older WORX mower, which struggled in similar conditions.
- Intellicut Saves Juice: The Intellicut feature intelligently adjusts power, extending the runtime considerably. I mowed my entire yard (about 1/4 acre) and still had battery life to spare thanks to this feature, even on days when the grass was particularly dense.
- PowerShare is Convenient: The PowerShare batteries are a huge plus for me, as I already own other WORX tools. Being able to swap batteries between the mower and my string trimmer is super convenient and reduces the need for multiple chargers.
- Versatile 3-in-1: The 3-in-1 functionality makes this mower really versatile. I switch between mulching and bagging depending on the season, and the included attachments are easy to swap out.
- Simple Height Adjustment: The single-lever height adjustment is so much easier than adjusting each wheel individually. I was able to quickly change the cutting height from 2 inches to 3.5 inches with minimal effort.
Cons:
- Plastic Deck Concerns: While the Aerodeck design is effective, the plastic material does feel less durable than a metal deck. I worry about its long-term resistance to impacts from rocks or other debris.
- Push Mower Only: It would be nice to have a self-propelled option, especially for larger or hilly yards. While the mower is relatively lightweight, pushing it across my entire lawn on a hot day can still be tiring.
- Bag Fill Could Be Better: While the Aerodeck maximizes bag collection, I did find that the bag fills unevenly, requiring occasional emptying even when it wasn’t completely full. This isn’t a major issue, but it’s something to keep in mind.
How It Compares
Alright, let’s dive into how the WORX Nitro 40V 21″ Cordless Lawn Mower stacks up against some of the competition I’ve had the chance to use. I’ve spent a good amount of time putting these mowers through their paces on my own lawn, so this is based on real-world experience.
WORX Nitro 40V 21″ Cordless Lawn Mower vs. Greenworks 40V 21″ Brushless Cordless Mower
The Greenworks 40V 21″ is a popular option, often sitting in the same price bracket as the WORX Nitro 40V 21″ Cordless Lawn Mower. I found it to be a solid, reliable mower overall.
Where the WORX Nitro 40V 21″ Cordless Lawn Mower really shines is its Aerodeck design. This clever feature noticeably improved the lift and suction, resulting in a cleaner, more even cut, especially when dealing with slightly damp grass. I also appreciate the Intellicut technology on the WORX Nitro 40V 21″ Cordless Lawn Mower. It automatically adjusts the power based on grass thickness, extending battery life and preventing bogging down in tougher patches. I didn’t see that level of adaptability on the Greenworks model. Finally, the 7-position height adjustment on the WORX Nitro 40V 21″ Cordless Lawn Mower felt sturdier and easier to adjust than the one on the Greenworks.
The Greenworks arguably has a slight edge in terms of overall weight; it’s a little lighter, which could be beneficial for users with smaller yards or those who prefer a more nimble machine.
My Take: If you prioritize a superior cut quality, especially with varying grass conditions, and appreciate the smart power management of Intellicut, the WORX Nitro 40V 21″ Cordless Lawn Mower is the better choice. However, if you’re looking for the absolute lightest mower possible in this class, the Greenworks might be worth considering.
WORX Nitro 40V 21″ Cordless Lawn Mower vs. Ryobi 40V 20″ Brushless Mower
The Ryobi 40V 20″ Brushless Mower is another strong contender in this space. I found it to be well-built and reasonably powerful.
I believe the WORX Nitro 40V 21″ Cordless Lawn Mower offers a wider cutting path (21″ vs. 20″), making it more efficient for larger yards. I also noticed that the bagging performance of the WORX Nitro 40V 21″ Cordless Lawn Mower was superior. The bag filled more completely, and there were fewer clippings left on the lawn after mowing. And while both are cordless and relatively quiet, the WORX Nitro 40V 21″ Cordless Lawn Mower seemed to operate at a slightly lower noise level, which my neighbors (and my ears) appreciated.
The Ryobi might have the advantage in terms of its storage footprint. It folds up a bit more compactly than the WORX Nitro 40V 21″ Cordless Lawn Mower, which could be important if you’re tight on space in your garage or shed.
My Take: If you have a larger lawn and prioritize efficient bagging and a slightly quieter operation, I’d lean towards the WORX Nitro 40V 21″ Cordless Lawn Mower. However, if space-saving storage is a major concern, the Ryobi’s compact folding design could be the deciding factor.

My Experience
My Three Months with the WORX Nitro 40V 21″ Cordless Lawn Mower w/Aerodeck & Intellicut, Brushless Electric Mower Up to 1/2 Acre, Push Lawn Mower w/ 7-Position Height Adjustment WG752 – Batteries & Charger Included
When I first started using the WORX Nitro 40V 21″ Cordless Lawn Mower back in early spring, I was primarily looking for a quieter alternative to my gas-powered mower. I live in a neighborhood where everyone is fairly close together, and the roaring engine of my old mower always felt a bit inconsiderate, especially on weekend mornings. What I didn’t expect was how much easier and more enjoyable yard work would become.
For the past three months, this mower has been my go-to for keeping my suburban lawn in shape. I’ve used it primarily on my front and back yards, which combined are just under half an acre. The first thing I noticed was how quiet it is – more of a gentle hum than a deafening roar. My wife, Sarah, even commented that she could finally relax on the patio while I mowed without having to yell over the noise!
During a particularly wet week last month, when the grass was thick and damp, the WORX Nitro 40V 21″ Cordless Lawn Mower proved its worth. I was worried it would struggle, but the Intellicut technology really came through. It automatically increased the power, and the mower sliced through the dense grass with ease. The Aerodeck design also seemed to help with lift, preventing clumping and leaving a clean, even cut. I also appreciated the 7-position height adjustment. I tend to keep it a bit higher in the summer to protect the roots from the sun.
I did find that on the thickest patches, the battery life was reduced slightly, but having two batteries meant I could swap them out quickly and keep going. Charging is also straightforward. The batteries click right into the included charger and are ready to go in a couple of hours. Compared to wrestling with gas cans and spark plugs, this thing is a dream. The WORX Nitro 40V 21″ Cordless Lawn Mower has genuinely made me look forward to mowing the lawn – something I never thought I’d say!
Final Verdict
Final Verdict
After a full mowing season with the WORX Nitro 40V 21″ Cordless Lawn Mower, it’s safe to say this mower has genuinely impressed me. My old gas guzzler is collecting dust in the shed. The convenience of cordless is a game-changer.
This mower is ideal for homeowners with yards up to half an acre who are tired of dealing with the hassle of gas and oil. If you’re looking for a powerful, easy-to-use, and relatively quiet mower, the WORX Nitro 40V 21″ Cordless Lawn Mower w/Aerodeck & Intellicut, Brushless Electric Mower Up to 1/2 Acre, Push Lawn Mower w/ 7-Position Height Adjustment WG752 – Batteries & Charger Included is definitely worth considering.
The biggest strength, without a doubt, is its cordless convenience and power. It tackles thick grass with ease, thanks to the brushless motor and Intellicut technology. The Aerodeck design really does improve bagging efficiency, which means less time emptying the bag. However, the run time, while decent, might be a little limiting if you have a larger or particularly overgrown yard. You might want to consider an extra set of batteries if that’s the case.
At its current price, the WORX Nitro 40V 21″ Cordless Lawn Mower w/Aerodeck & Intellicut, Brushless Electric Mower Up to 1/2 Acre, Push Lawn Mower w/ 7-Position Height Adjustment WG752 – Batteries & Charger Included offers excellent value, considering the included batteries and charger.
Based on my experience, I highly recommend the WORX Nitro 40V 21″ Cordless Lawn Mower to anyone looking to make the switch to a cordless lawn care solution. I think you’ll be pleasantly surprised by its power and performance.
