80V 21in Push Lawn Mower, (2) 2.0 Ah Batteries and Charger

My 19-year-old John Deere mower was getting hard to start. I ran across a fantastic deal on the Greenworks Pro 80V 21-inch mower with two 2Ah batteries and charger in the fall of 2017. It cost only $40 more than the lowest price I could find for two batteries, so I figured let's try this mower out. I was excited to try a battery operated mower for instant start (pulling a tight string multiple times to start was getting to be a chore); plus no oil changes, no air filter or spark plug to change, no having to run the gas out at the end of the season and store for winter. I was losing self-propulsion, but I have a flat yard and the Greenworks mower is much, much lighter, so this was of no consequence for me. In fact, I prefer to push the Greenworks mower as I can go at my own speed instead of walking at the slow or even slower speed of the self-propelled mower. The mower has worked great, and I'm into my fourth season mowing with it. In fact, I liked it so much I also bought a Greenworks 80V trimmer, blower, hedge trimmer, and snowblower and interchange the batteries for all of them. I sold my gas trimmer and blower, and my snowblower had died, so that need replacing anyway. I've had no problems with the tools. One of the battery chargers died a few months into ownership, and Greenworks replaced it under warranty at no cost to me. This year I could start to see some blades of grass remaining standing after mowing, so I decided it was time to get a new blade (the old blade has a number of nicks from rocks and such). I ordered a replacement blade direct from GreenWorks during a Memorial Day sale, and they shipped next day. The blade was a very simple replacement -- just use a wrench to remove the large bolt, then remove and replace the blade in the same orientation and twist the bolt back on. I didn't need directions nor had to watch YouTube videos, even though this was the first time I ever replaced a blade myself (with my old mower I always just paid someone to sharpen it, the new Greenworks blade cost the same as two sharpenings, so I just decided to get a new blade.) Now my grass is cutting perfectly again. Also, I noticed one reviewer thought the mower was difficult to put together. That person must be mechanically deficient, as attaching the handle isn't difficult at all. All my neighbors have asked about my mower, because it operates at a much lower decibel level than gas mowers. When I bought the blade I also purchased a 4Ah battery, and now I can mow my yard in one charge (with the two 2Ah batteries I had to switch out the batteries mid way). It takes about 50 minutes to mow my yard. This being my 4th year of ownership, and using the batteries year round for yard and snow removal, I am seeing shorter battery life with my four 2Ah batteries. Maybe about 20 minutes of runtime vs. the 30 I used to get. Which is why I invested in the 4Ah battery, which is perfect for my mower. I'm using the 2Ah batteries in my other hand-held yard tools as it is better to have the smaller, lighter battery for those. The 4Ah is a little large in the blower but still works OK, but I don't need to run the blower for maybe 15 minutes tops, so I use the 2Ah so I don't have to deal with the weight. I wouldn't want to try the 4Ah battery in the trimmer or hedge trimmer either as the weight would make it more difficult to use those tools. I highly recommend going with Greenworks 80v battery equipment. I absolutely love the Greenworks tools I am using. I find them to be equally as effective as gas tools, just without the noise and gas fumes. (You don't smell like gas and oil after using your trimmer/blower.) You don't have the maintenance on Greenworks either like you do on gas-powered equipment. If you make a list of pros and cons, the pro list will most certainly outweigh the cons by a large margin.

This mower is easy to set up, easy to use, and cuts tall grasses with ease. My previous gas mower was no longer working and I ordered this Greenworks 80V because I was tired of the maintenance and mess of a gas mower. I didn’t expect much, honestly, because I have a large property and never expected an electric mower to be able to handle the job. I was very pleasantly surprised; the lighter weight and high power makes the job quite easy. Having two batteries that charge quickly means I can get the job done by swapping batteries and keeping one on the charger… I never ran out of power. Also, because it had been several weeks, the grasses had grown 8-12 inches tall in many places, and were slightly wet from the rains. This mower did the job without any trouble. I’m very, very pleased! Since the same batteries can be used in other Greenworks tools, I’m going to start replacing all of my yard tools with Greenworks 80V tools… Next up is a string trimmer, then the pole saw. After that, we shall see.

*** 2024, still going. Not one thing failed on this (aside from blade from hitting rocks and junk, which happens to any mower blade). Overall, gotten used to it. Just put in battery and go. Batteries still going strong too. *** Now that it is 2021, it still works. I've changed blades a couple times for rocks, sticks, etc. that it hit over the years since 2017. Just pull it out of the shed, put in battery, go. It just works. Runs about an hour, charge battery, use 2nd battery, go pretty much endlessly. Cut tall stuff, sure, lose some time on the battery. For me, forget gas powered. Stinky, loud, heavy, hot, and pulling that annoying cord!! Oh, and spilling gas, gas fumes, the oil, disposing of both ... no, no, no. For battery mowers, I like this one with two batteries - a lot. For a trimmer, I actually went with the EGO carbon fiber straight shaft. Pricey thing, that. No guide wire to really let me do precision around delicate stuff (still use a B&D for that work), but it does alright. Never used a gas weed trimmer so nothing to compare it to besides the B&D cordless models, which in no way compare to the EGO's ability to shred tall clover and similar thick stemmed plants. B&D vibrates so much, my hand tingles after an hour or so. Can go a lot longer with the EGO, but it's heavier, for sure. ** *********** Earlier review... Overall, good mower. Easy to move around. Cuts well. Fairly quiet. If your hearing is really good, you might want ear plugs. Mine's less than good and I barely notice the low speed. On high speed, that is noticeable. Almost no odor out of the box. Battery charger stinks first few times when charging batteries. Go into room and think 'what is that smell? yuck.' After charging a few times, odor just keeps going down. Barely noticeable now. Cuts grass as tall as the motor housing. Be prepared to go slow though. When I did manage to kill it in thick grass nearly as tall as the motor (well above the front wheels), it likes to wait a few seconds before starting again. Starts right up (until the battery is out of juice). Batteries last about as long as advertised. Didn't put a clock to mine. By the time one is used up, the other is charged on the charging device. I tend to stop and pull weeds or other stuff (like pine cones). I can pull this out of the shed, fold the handle into place, put on the bagger and just go. It's easy, it works, and handles what my gas mowers can handle. Anything the mower leaves little bits of uncut stuff ... the grass was thick, damp, and resistant to cutting well ... even with the gas mowers, I'd have to do that area twice. The dry grass, even thick dry grass, it just cut it all. Just slow down a little if you find pieces of uncut stuff and it will get that too. I like the bagger attachment. No more raking. My shoes are not covered in grass clippings. Picks up nearly all of what it cuts. I can't see anything down there but maybe it left something someone with better eyesight could detect. When the bag gets full, the weight shifts to the rear. Front wheels come off ground easily. You'll notice it's heavier in the rear, takes more effort to move, and if you keep going ... stuff will be left behind (cause the bag is full and it can't go in there). Empty the bag and you're all set. Overall, I am very satisfied with this mower. No gas fumes. Unit itself doesn't stink. Battery charger odor diminishes with use (the more batteries I charge, the less it smells). I don't have to rake with the bag attachment. The two batteries allow me to keep going until ... well, my body won't "go" anymore. Use one battery, charge the other. Seemingly endless run time with just the two batteries. Of course, you might have to wait in between the batteries if you run one out faster than the other (like with really tall grass). Mower cycles itself high and low depending on what is being cut. Does this automatically. I find that when it revs higher, it can leave some stuff behind. So, I just pause while it revs up, back the mower up a couple inches, and then go forward. Seems to leave nothing behind that way. The mower will cycle down to the lower speed on its own. I have cut grass higher than the front wheels and the mower stayed on the low setting. And I have cut grass shorter than the front wheels and had the mower go to high. Depends on the grass characteristics. Also, if using the bag, depends on how full the bag is. If the bag is full, you will be on high almost constantly. Change the bag and it will go back to low, unless ... of course ... you are in tough grass and it needs high. The things I dislike are minor. #1, the knobs on the handle. These things spin on easily ... and off equally easily. I would prefer a design like at the bottom of the handle. Twist the handle to move the pin in and out. No screw, no knob to fall off. Something like that would have been better than the knobs that can (and do) spin right off when trying to fold and unfold the handle. #2, the wire gets caught on the rear panel When changing the bag, you lift up the rear panel. To get the bag's hooks onto the mower, you will likely need the rear panel almost vertical. This puts the panel above the wire that connects the mower to the safety button for starting the mower. Even though there is a sheath around that wire, the wire moves away from the metal handle and can get caught by the rear panel. So when you lower the panel, give an eye to the wire. Make sure it's clear or it will catch. It won't get sliced in two, but I doubt the wire sheath wants to be clamped down by the rear panel's retaining springs on a frequent basis. #3, the bag is hard to empty Okay, if you have a wide mouth can, you can just lift up the bag and shake it to your heart's content to get the stuff out. Got just a bag on the ground? Put the bag over the bagger with the grass, flip upside down, shake. And then you start to wonder why you are lifting the entire weight of what you mowed and shaking it to get the grass out. You can hold the bagger piece upside down and the grass won't fall out much. Getting the grass in is a breeze. Getting grass out ... is a delaying annoyance. I just scoop the grass out one gloved hand at a time into a trash bag, because I am not a body builder who wants to shake a full grass bag into a bag ... and the bag keeps shifting ... it goes everywhere on me or I'm tired or both. Still enjoy no raking, so a few minutes of rest while scooping grass doesn't bother me. The grass should come out easier. Have not used the side discharge or the mulch. I'm so happy with the bag, that I'm going to keep using that. Cuts like my gas mower. Quieter. No fumes. Revs up when it needs to. The EgoPower mowers are nice looking alternatives. Most of the decks are plastic. The voltage is 56V for their stuff instead of the 80V with the Green works mower. The Ego handle looks nicer (no knobs to fall off). The Ego can fold up into what looks like a smaller space and be stored on its side. That's neat. The LED lights on the Ego made little sense to me until I mowed tonight at dusk. Saves me from covering up with suncreen to go mow for a few hours ... I used the neighbor's yard light (ha ha) to see the grass. He didn't seem to mind. I wanted the metal deck so I got the Greenworks mower. I have a corded greenworks mower and that worked alright for me. I got tired of the cord for all the trees and obstacles around here. The battery mower is a dream. No cord to mess with. Mow when I want, where I want. Easy. No long wait times on battery charges either. About 30 mins and it's charged. I haven't made it back to the station with am empty battery before the one charging was already full. The Ego mower with the metal deck was over $700 at Home Depot. The Greenworks mower was a more tolerable price point. The foam on the corded mower goes all the way around the corners of the handle. The foam on the battery mower stops at the corners. I thought it would bother me at first, but it doesn't. I don't seem to grab the handle at the side corners so it's no issue for me. Greenworks could've used a non-sticky adhesive for the sticker on the safety bar. Sticky gunk. I wear gloves anyway so it doesn't bother me. I keep saying to myself, someday I'm going to get out the olive oil and rub that gunk off. The sticker on the motor housing has a wrinkle in it. Oh well, but it's their brand, the sticker ought to be better. Oh, when folding the handle ... the metal rubs on itself and wears the paint off. So right where the knobs are, be prepared for scratches unless you want to treat it like a fragile egg when unfolding. When folding, it doesn't seem to rub as snugly. So, yes, minor stuff I don't like. Very minor. It's a mower. Who cares about stickers? It does the job. I'm happy with it. PS: Both Ego & Greenworks have metal blades mounted onto plastic parts. I was worried the blades might just shear off. I checked my corded Greenworks mower and it is the same deal, metal to plastic. No blades flying off. Whatever plastic they're using, it seems to hold up just fine to the stress of a whirling blade. If the Ego wasn't several hundred more than this mower for a metal deck, I might have given it a try. But their batteries are expensive if I wanted an extra one (ditto for Greenworks). The Greenworks mower already has two batteries and that's enough for me. Yes, this is long winded. I was out mowing long enough to drain 2 batteries today, weed eat, and pull weeds. Multiple hours outside. Very happy with the mower overall.

Note: At the moment Amazon is not currently directly selling the model (Greenworks Pro 80V 21 inch Cordless Push Lawn Mower, 2 2Ah Batteries and Charger, GLM801601) I'm reviewing. At the time of this review we've mowed our yard ten times since receiving one of these electric mowers. I like this lawnmower system enough to recommend it, despite some caveats. It does what the advertising says. The batteries last, as long as you don't mow a lot of thick grass quickly. I can mow my whole yard on one battery charge, rendering moot the ability to continue mowing with a second battery while the depleted first battery is recharging. What the advertising doesn't say is that, while it is as powerful as a 160-cc gas mower, that only applies when the electric mower is running at full power. My 149-cc gas mower can easily vacuum up leaves from the lawn at the normal height setting, but that only happens with this mower if the engine revs up, and that is not a manual setting. The motor will automatically speed up in dense grass, a nice feature, but it would also be nice to choose that higher speed to use it to pick up leaves as we did with the gas mower in the fall. I would willingly sacrifice battery life for this ability. Otherwise it cuts grass reasonably well, as well or better than the gas mower. One really nice feature is the large-capacity rear grass-catcher bag. It holds about twice as much as the gas mower's bag, and it is better designed to keep the clippings inside the bag; the gas mower's bag is tilted toward the front which causes the clippings to slide forward and block the opening as one mows. This bag has a horizontal bottom that helps retain the clippings and the opening won't be blocked until the bag is truly full. And you can lift the lid at the front of the bag to examine how much is in the bag without having to remove the bag from the mower. (On the gas mower, checking the bag by lifting the lid would allow clippings to fall out, defeating the purpose of checking. It was possible to lift the front end of the mower to prevent the loss of clippings when lifting the lid, but -- trust me -- this is awkward.) Because of the larger practical bag capacity, I no longer have to stop a couple of times to empty the bag while mowing the front yard and then repeat that in the back yard, as I did with the gas mower. This also means I don't have to drag the 40-gallon trash can for the clippings to the front yard and then back to the back yard. I've gone from emptying the bag six times to two when mowing the whole yard. It's not all positives here, though. The low position of the bag means that the rear end drags on the ground when you lift the front end to rotate the mower to reposition it for mowing another row. This quickly wears the fabric on the lower back seam. I've put duct tape there for now, but a good hard-plastic sealant strip along that seam would go a long way to extending the life of the bag. And the bag capacity can mean more effort needed to empty a full bag. If you have trouble with this, you might want to consider checking the contents of the bag (the lid makes this easy) as you go, and empty it sooner. And finally, I have to check to make sure the bag lid has fully seated before resuming mowing. One of the lid's two plastic notches has a tendency to just catch the bag frame's metal rod on one edge, so it needs a little tug to the left to fully seat properly. I didn't test the mulching capability, but I did like the large plastic plug that fills the opening at the mower back, very likely making the mulching feature much more efficient. Nor did I use the side discharge chute. The side door does trap clippings when closed, though; it does not quite fit flush with the chassis side opening. It's much quieter than the gas mower in operation. Even the wheels are quieter, perhaps because they have bearings. A very good feature is the all-wheel height adjustment lever, which can be moved on the fly. This feature does extend the front of the mower a bit, so it's harder to mow close to a wall in front of you because the blade won't reach as far. That just means a little more edge-trimming. The charger is very fast! And it has a loud fan. Also, the charger didn't have any noticeable odor; it might have been burned in longer than those used by other reviewers. Since we are keeping the batteries indoors to help extend their lifespans, we're trying to figure out a place to put the charger that won't disturb those in the house. But it does indeed charge the 2Ah batteries in less than half an hour. The mower is easily maneuvered but it is not light. I wasn't using the self-propelled feature of my gas mower, but it turns out that my wife did, and now, knowing what I know, I would have gone with the slower-charging single-battery self-propelled mower version over this one. I might still do that, after some time has passed. Edit: If there is one; the model is not listed at the moment... As mentioned, I recommend this electric mower. It doesn't smell of gasoline, there is no gas ($) to put into it, no oil to change ($), and no trips to the gas station to fill a gas canister ($) and then pour in a fuel additive ($) to compensate for the ethanol in the gas. When this is combined with the higher-capacity bag, I'm now finished mowing in half the time. Maybe Greenworks will see this review and make some changes, so that the next model will get five stars. But this unit is still very good at what it does.

I put off buying a battery-operated lawn mower for years - waiting for the batteries to improve and the mower's quality to improve. This steel deck 21 in. mower with 2-80V batts runs like butter. I had it set on two for the height, with the bag attached, and it cut flawlessly today, 15 minutes after putting it together and tossing a battery on the charge. It “vacuumed” up leaves as I cut, leaving the yard nearly spotless. Gone will be the days of bagging 40+ bags of leaves over the fall. I’ll just cut once or twice a week from now on. Filled up two leaf bags with grass clippings and leaves. I hit it with my leaf blower to clean off the dust and dirt; it looks brand new. It’s a little heavy given the build, but it was easy to push. I would’ve loved a slightly larger catch bag, but it did the job well. I’ll be investing in some more Greenworks yard tools compatible with the batteries, that’s for sure. After using a reel mower for four years (that gave a good cut), I think the value for the money is in the consistency of the cut and the battery power. I barely used one battery for the whole yard, and that was with using it as a vacuum over the sidewalk and driveway to pick up residual leaves. Glad I pulled the trigger.

Love it. I have two batteries. So able to keep mowing. Only complaint is it is impossible for me to release the battery in the mower to change out

Yes, it is expensive - but this is really a good mower. I wanted to avoid dual blade & dual motor models. I wanted to have the higher battery voltage for more power with less loss (higher efficiency). Remember this is an 80V system - highest on market today. The battery lasts about 30 minutes in thick grass (therefore high power mode) with a sharp blade. This thing automatically revs up the power when the loaded increases - while still remaining insanely quiet. Then it throttles back when its no longer heavily loaded for a short time. Super light and easy to push. Feels well made. I think keeping a sharp blade will make a big difference long term. I'm the kind of person who will occasionally let my lawn get out of control, so I wanted to make sure that when it happens, the mower will rise to the challenge. Well folks, it happened last week... After weeks of rain and a busy schedule I finally had a challenge for my mower. I had no problems with the super thick grass. At the time I was using side discharge. I can't say about mulching - I have done it once by accident (forgot to take the plug out for bagging) and it didn't flinch with an average to long grass length. (We are talking about typical Minnesota lawn grass) I the neighbors sit and watch me mow with it - they can't believe that I'm having a phone conversation while mowing my yard. Funny story, I almost ran over my girlfriend when she walked around the house corner the same time as me - she had no clue I was back there mowing! I'm an electrical engineer and I approve this mower.

After 4 months of product usage I have a few mixed feelings about this mower. The yard I mow regularly (the front) is roughly .25 acre, and the good news is I can get it done on one battery with still a single light remaining on the battery. This is of course depending on me staying on top of the yard and not letting it get too thick and tall (forcing the mower to pick up into high gear all the time). Cut performance is good, but the issues I have are around general material quality and forethought. Motor and battery life are good; it's easy to start, easy to keep running, quiet, and has good battery life. The grip handle fell apart on one end after just two mows, forcing me to tape it up before it got much worse and somewhat affecting operator comfort. The deck height, while easy to adjust, just doesn't get tall enough, especially during the drier months of the year. I have run the mower at the level just above the tallest notch in the setting rack (off the chart), but found it not to translate to all four wheels, resulting in an inbalanced deck\cut. The stitched handle on the end of the bag has started to fray, and I think will soon break from the back of the bag. Lastly, I find that the desk height system is a bit "soft," making the front wheels have more of a suspension vs a definitive height. I'm fairly certain I was OK with no built in propulsion, but boy do I miss it some hot days. I have fully committed to the product line having purchased the mower, string trimmer, pole saw, backpack blower, and hedge trimmer. I believe next on my list is the chain saw, but that appears to be limited availability. I get great performance out of the full line of products and kept the price down with only running a pair of chargers and three batteries. The interchangeability of batteries to products is a big selling point. I can normally get the entire lawn done on one 1hr and one 1.5hr battery between mow, trim, and blow. Overall I think there is a lot to like about the Pro series of products, and I believe as the company gets more real world reviews like this they can make improvements to the little annoyances that only present themselves through real world long term usage.

What a great mower! I have a huge yard and for years used a Toro Timemaster 30" Personal Pace (self propelled) dual blade mower but even with the personal pace option it was still it took some effort to maneuver It worked great and cut my mowing time in half. I wanted to opt out for something a little lighter and this mower is perfect. It The 80V batteries last a long time. I did my entire back yard on one battery and I have a very large back yard.

We downsized from 5 acres to a small yard - it took 5 hours every weekend for just a basic mow. Every. Weekend. Now with a small yard we have to *schedule* taking turns with this lawnmower. Seriously, it’s light, powerful, quiet and dead easy to use. And the price is fabulous.

Been converting as much stuff as I can to electric due to it being more environmentally friendly, and convenience of being able to charge batteries off solar or any other source. Already have other Greenworks 80v tools (chainsaw and electric shovel) so I now have 4 batteries. Only used the mower twice but I have to say I'm impressed so far. It's powerful and feels like using a gas mower, even tried it while it was raining in very wet grass and it went through without issues. The battery life is not quite as good as they advertise but I presume that's based on only mildly tall dry grass. It rains a lot here so even on a good day the grass is going to be humid from all the rain we had before. Either way, it takes 2 minutes to swap the battery so battery life on stuff like this is really not that huge of a deal as long as you have 2 or more batteries you're always going to have power. It's faster than adding gas.

Quiet, cuts well. We also have the snowblower too so can switch off the batteries on both to get more grass cutting/snow blowing time - or take a break for half an hour and go at it again!

Cette tondeuse sert à tondre ma pelouse sur mon terrain d’une assez grande superficie. Je l’adore. Elle est silencieuse, facile à partir et à pousser. Ses deux batteries de 80 volts sont suffisantes pour la tonte que j’ai à exécuter. De façon générale, j’utilise l’énergie d’une batterie et demie à chaque utilisation. La hauteur des roues est très facile à ajuster. La seule amélioration à apporter à ce produit serait que l’extérieur des roues soient en lignées avec le bout de la lame pour une tonte plus rapprochée des surfaces verticales tels les abords des bâtiments.
