Features:
Easy Movement Meets Exceptional Cutting Power
Cut Without the Clogs
This cordless mower's innovative Aerodeck features a vented design to draw more air into the cutting deck to prevent clippings from clogging and clumping. The boosted air volume also improves cut quality, maximizes efficiency, and ensures more grass gets into the bag.
Ideal Runtime for Up to 1/2 Acre
Brushless Motor 2.0 technology boosts mowing power and extends runtime to level up your lawn care and get more mowing done on a single charge. And with the included (2) PowerShare Pro 5.0Ah batteries, the mower offers a max no-load runtime of 50 minutes, which is perfect for mowing up to 1/2 acre without having to recharge.
Smarter, Self-Propelled Mowing
IntelliCut technology automatically adjusts the cutting speed to fit your grass conditions, optimizing performance and runtime. And with its variable speed self-propel, the mower lets you set how fast it goes and avoid the strain of pushing---simply guide it over the grass with ease.

Love my Worx tools,mower,weed eater and chainsaw
[This review was collected as part of a promotion.] I received my new mower and it is so much better than the gas powered one that I own. No more pulling until your arm falls off to get it started. I really like the option to bag, mulch and shoot grass out the back instead of the side. It's super easy to use and very minimal put together. I've not gotten to really put it to the test yet because it is still cold here but the bit I did use it was very nice. I'm excited for when I do have to finally cut grass. Lol

Safety Feature Works!
I purchased last year’s model and have used it on steep hills. The locking wheel feature saved me more than once. What another reviewer said about locking wheels is not quite correct. The wheels unlock after a few seconds. This holds the mower to avoid slipping but releases it so you can continue. This mower consistently does a great job. I use the mulching feature all the time and love how leaves, grass and anything small becomes fine mulch. I never have to rake excess grass and I don’t cut the grass very often.

Great Mower with Quality Features!
[This review was collected as part of a promotion.] Just purchased the Nitro 80V mower and I was presently surprised as to the overall quality and how well it was designed for easy usage and durability. My previous mower was a gas powered Toro personal pace model which served me quite well, and henceforth my standards were quite high when comparing these mowers.
PROS:
1. Just mowed less than 1/2 acre, and the battery still shows between 1/3 and 1/2 capacity still left.
2. The cut quality was quite excellent.
3. The mower is very quiet compared to my gas mower.
4. The speed control for the self-propelled drive is quite easy to adjust.
5. Love the feature that allows you to easily remove the entire battery pack which makes it quite easy to recharge all of the batteries at once.
6. By removing this battery pack, it allows you to easily clean the top and bottom of the mower deck. Also the underside of the deck is designed for easy cleaning without any hard to clean cavities like some mowers have.
CONS:
1. The mower has a tendency to take off very fast when the self-propelled drive is engaged. This only occurs for a brief second or two, but it is easy to get used to.
2. The owners manual is extremely difficult to understand and is totally useless.
3. There needs to be a replacement parts guide that also shows the correct part numbers for each item. Right now there is nothing available.
4. Long battery charge time. 4+ Hours

Battery charger
[This review was collected as part of a promotion.] My apologies, I just posted a review regarding an external battery charger not being included in the box and after reading another person's review, realized the battery charger in the lawnmower does come off for external charging. Should have read the reviews before posting. Again apologies.

Great mower
I initially reviewed this product as poor. What is bad, no awful are the instructions. I am not the first to complain the mower runs but blade doesn't turn. There are no written instructions, just pictures. A few words at each picture would make a lot of frustration go away. You most hold the start button down when you pull the black bail to the handle.

Perfect for my lawn in every way!
I've suffered from low back disc problems for over 5 years. This is a fantastic light-weight alternative to my old gas-powered mower. Batteries last plenty long for my mid-sized lawn. Love the ease of height adjustment and switching between mulch and bag in a flash!

Very user friendly
[This review was collected as part of a promotion.] This lawnmower has been such a game changer!!
Really amazed with how powerful it is for its size and the stripes and clean cut it outputs.
This is definitely the quickest I’ve ever adapted to a new lawnmower, and got comfortable with it immediately.
As a newly single mom, this was the perfect lawn mower for me to have and operate.
Battery life is great and I also love the deign and simple look of it.

Impressive Performance for Lawn Enthusiasts
[This review was collected as part of a promotion.] The NITRO 80V 21" Cordless Self-Propelled Lawn Mower has completely won me over as my first electric mower. I'm genuinely amazed by its performance. Equipped with the 5 amp hour batteries, I can effortlessly tackle my 6,000 sq. ft. lawn, often completing nearly two full rounds on a single charge.
As a lawn enthusiast who prefers not to let my lawn grow too long or cut it too low, this mower has been a perfect fit for me. It handles my needs with ease. The power it delivers is truly impressive, making the mowing experience efficient and enjoyable.
The inclusion of the intelli-cut feature adds a layer of convenience, but I do wish there was an override to switch it into high output mode. While it's useful for regular mowing, there are times when I'd like that extra power to tackle particularly challenging areas.
In summary, the NITRO 80V 21" Cordless Self-Propelled Lawn Mower is a fantastic choice for lawn enthusiasts. It offers impressive battery life, powerful performance, and the convenience of cordless operation. The only minor improvement I'd suggest is the option for an override to access high output mode. Nevertheless, I'm thoroughly satisfied with this mower and highly recommend it to anyone looking for a reliable and efficient lawn care companion.

This is a Beast!
LOVE this mower! Honestly can’t say there’s a gas powered mower out there to beat it. I have a half acre corner lot and nothing has stopped it yet. One feature I really like is the way the batteries are contained…simple pickup the “base camp” from the mower, take it inside, plug it in. All batteries suitcase style. Very well made mower, does a great job on the grass, folds up when done. Extra weight is handled well with the self propulsion. I am a 55 yr old disabled female and had no problems with it.

WORX Nitro 21" 80 Volt mower a real pleasure to us
[This review was collected as part of a promotion.] I recently decided to purchase the WORX Nitro 80 V 21” Self-Propelled brushless lawn mower. My immediate concern was the power and if it would be adequate to handle my average size yard. I am very particular with my lawn and the appearance. I often switch between mulching and bagging. I have used this Nitro for three consecutive cuts and could not be more pleased with the results.
It has all the power I need with battery to spare. The ease of use is amazing. One lever adjusts the cut height on all 4 tires and one sets the speed. One cord quickly charges the 4 each 20 volt batteries which is removable to bring inside in the winter. My yard is looking great and I am pleased to help our environment with no more gas and oil cans.

Best Electric Lawn Mower Available
[This review was collected as part of a promotion.] This is the best electric lawn mower on the market without question. The battery life is excellent and the PowerShare BaseCamp charging system is a must have for those that own multiple PowerShare products. The full BaseCamp can be easily swapped in and out with the press of a button and has a convenient carrying handle. Currently only this mower and the backpack blower utilize the BaseCamp as a power source. With that being said the BaseCamp when not in use in one of those products can charge four of your PowerShare batteries at once, regardless of their size. Battery life is adequate, but I do need two full BaseCamp charges to get through my yard most of the time (100'x150').

Complete SHOCK!
[This review was collected as part of a promotion.] I’m gonna be honest here.. I’ve never owned a electric mower or any kind before until now because I always thought they wasn’t powerful enough or able to get the job done but I was 1000% WRONG & here is why. Sizing is perfect,Weight is very light that I’m able to get it into my ditch & up/down my hill with no struggles,the cutt is perfect,speeds are perfect for all jobs,bag for small jobs works better than expected,headlight is brite for those late noons,Battery life has me shocked as it lasted 2 full yard mows which I timed at 10.8 hours & still had battery life. This pushmower has made my life so much easier & eletric/worx will be in my future from here on out! Thank you for the absolute BEST EASIEST JOB. You’ve gotten a forever customer now!

Nitro 40V Self-Propelled Lawn Mower
[This review was collected as part of a promotion.] The mower works well. I upgraded the battery and can now cut the lawn twice on one charge. I would suggest upgrading the battery to an 8 amp when there is a sale. I have two other Worx Mowers and purchased this one which has more features including an LED light to see when the Sun goes down. All have been excellent. The battery sizes have gotten smaller with the new models.

Just Like Butter
[This review was collected as part of a promotion.] I love, love, and love my new 80v mower. It has more cutting power than my older self propelled large wheel gas mower. My 30 year old reliable mower was just too hard to start every time plus having to change the motor oil and add gas. The Worx 21” self propelled battery operated mower is so much easier to use. You push a button and you’re off. It is also so quiet compared to the old mower, easier to push and clean up is easy….just dump your clippings in the trash and blow off the mower and you’re done. I’m also able to get very close to my flower beds, under my yard swing and edges of my mulch with no issues. Another great feature is that you can easily adjust the mower blades using the lever on the side of mower. I can mow my yard 1/4 acre three times on one charge easily. If I do run out of power I can use my batteries from my trimmer etc… but that has never happened I’m a 64 yr old female and the grass is a breeze to cut just like butter…smooth.

Simply Love It
[This review was collected as part of a promotion.] Of all the Worx products I own, this just might be my favorite. No more gas, oil, filters, spark plugs, winterizing - What's not to love. It has more than enough battery life to cut the front and back lawns.

Fantastic Lawnmower
[This review was collected as part of a promotion.] I absolutely love my new Nitro 80V 21" Cordless Self-Propelled Lawn Mower with Brushless Motor and Rear Wheel Drive. Everything you need comes in one big box and there's no need for tools because it comes pre-assembled. You do have to put the side guard or bag on when you use them, but that’s to be expected.
The basecamp for the batteries detaches from the lawyer so you can charge the batteries inside your house. It took about 6 hours to charge the four batteries and I was able to mow a little over 1/4 of an acre before they needed to be recharged.
This Nitro 80V 21" Cordless Self-Propelled Lawn Mower with Brushless Motor and Rear Wheel Drive is an absolute workhorse. It cuts through tall tough grass with ease and automatically adjusted the cutting speed when I encountered thicker grass.
I almost forgot, I am almost 5'2" and I was thrilled to learn that the handle can be lowered to fit my height.
My only negative about this lawnmower is the lack of written instructions. Following the diagram on the lawnmower, the lawnmower would not start. You have to hold the start button down for a few seconds and then, while keeping the button pressed down, lift the black handle.

No more gas mower!
[This review was collected as part of a promotion.] I have had this mower for a week now and can’t get over how much it’s changed the way I mow. To start off, the ease of this mower is unmatched when it comes to changing settings and storing it. Using simple levers you can collapse this mower and store it on its side (unlike a gas mower) and take up less space in your garage. The three speeds help you match the speed that matches your pace and the self-propelled function feels like you’re not using any energy at all. The four 20v batteries get charged over night and are ready to go the next morning. I have been able to mow my 1/2 acre of land without it dying. The mower comes with a bag to catch any clippings but can switch to the side discharge very easily with the pull of a lever. Overall, this mower has just as much power as my gas mower did and cuts out the hassle of having to buy gas every few mows. I love this product!

A pleasure to mow my grass!
Very easy to use, light and self-propeled. Enough power to mow all my yard without recharging. The plastic latch to fold the handle is fragile and can be broken easily.

Easy operation
Easy to operate. Only issue the instructions were not very clear on how to start ( Push start button and then pull back on black lever) There were times I had to repeat to get started. Maybe from pulling back black lever to quickly. Over all with 5amphr batteties I was able to mow 3/4 of my acre of land. No problem put in the 2amphr batteries to finish.

I absolutely love the WORX product line. I am 81 years old and my last purchase of the 21" self-propelled lawn mower was the best yet. I started with the 12", then went to the 14" and finally gave in to the 21". Thank you for a fantastic product.

My first battery-operated mower
I really love this mower. I used it for a few weeks now and it cuts through long grass beautifully. I was able to mow for about 90 minutes, only using the propulsion on a few hills. So easy to turn propulsion on/off and change the speed. Highest speed is FAST, which is great for running mower back to the garage. Battery pack removes easily for charging. Took me about 7 hours to charge from 0 to 100. My only con is that grass gets stuck in exit chute, but I find that I can shake/bounce the machine to get it out without stopping. Highly recommend.

Worx Nitro 40V 21" Self-Propelled Lawn Mower
Ordering is EASY!, Shipping to my door was very fast, Mower arrived in great condition and was already assembled in the box. Just take out and unfold handle to mowing position. The mower is so easy to push with its comfortable 3 position handle that I find I don't even need self propel mode. The run time is excellent on the supplied 5AH batteries. The quick charger is just that, very quick to recharge. Some of the features I like most are how you raise and lower the deck with one push of a button on a handle. Another most valuable feature is the lever to switch from mulching to vacuuming up into the included bag. And the hard bottom of the bag is another nice feature. The best feature I have found is when I go up the front slope in the front of the property. The variable speed drive. Awesome! The little lever can be used like a gas pedal to speed up or down while mowing. I don't know why I waited so long to get a cordless mower. This mower is so well thought out, well balanced and just absolutely a pleasure to mow again. If you have a 1/3 acre or less, and don't want a riding mower, then this is your mower. It somehow just glides through the yard. Also love the intelligent motor controller too. High grass, it speeds up. Short grass, it slows itself down to save battery. Highly recommend this mower.
