Greenworks 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.

I've owned big Toro power mowers for over 40 years. They work great and last a long time. But they are also loud, emit lots of exhaust and use gasoline that always seems to run out at the most inopportune times. I hadn't thought much about electric lawn mowers in the past because battery technology hadn't yet evolved to provide the needed power, and cords were out of the question. But last year I got a new neighbor, with a bright green electric mower that was quiet and large and seemed to do a great job mowing the lawn. So, when my 6.5 HP 22 inch Toro needed another coil, and I assessed the rusted out deck, I decided I needed a replacement and I took the risk that an electric mower would do the job. I am so happy with my Greenworks PRO 80V 21 inch mower that I feel compelled to tell about it. It is an amazing machine. Much lighter, and easier to maneuver than a gas mower but with plenty of power to cut tall, fast-growing fescue in the Spring. The mower is sturdy and strong, with a nice wide cutting area and a rear loading bag that is generously large. There are few moving parts, so it is simple to use. And I am surprised at the length of time that the mower will run on a charge. I chose to get two 2.0 AH batteries vice one 4.0 AH battery because I figured that I could keep one on charge while I used the other. But I've found that I can mow my entire 1/3 acre lawn with just one battery in about 50 minutes. The mower senses the needed torque to cut the grass and automatically shifts into "high gear" when necessary, which will cut down on battery time if the lawn is especially high or you cut the grass very short. But for normal, weekly cutting, the low speed seems to do the trick nearly all the time. If I ever need to cut the brush behind my fence, I'll probably miss my massive, gas-guzzling Toro. But for my weekly tending of the yard, this mower is my choice, hands down. Not only does it do a great job cutting grass, I can also feel good about my small contribution to limiting emissions. I've now got a battery powered blower, edger and mower. They all work as well as their gas-engine counterparts and I'm not bothering my neighbors with all the noise pollution. I wish they'd switch, too!

Backstory: I’ve been using my refurbished 25+ year old gas (Briggs & Straton) lawnmower for the past year and half since my lawn service quit on me because it was not worth it to them to stop and cut my 2/10 of an acre lawn once a week (spring and summer) and every two weeks in the fall and winter – it’s a Florida thing. Spent $60 for parts (did the labor myself) and paid for some gas and considered pushing this thing once a week as part of my exercise routine. Tall grass and tiny wheels make for a challenging workout. Last week, it sprung a gas leak, and I decided it was time to move into the 21st century. Did a lot of research beforehand because I knew this time was coming and settled on the Greenworks 80V push lawn mower version. When it was delivered in its carton my first thought was WHAT DID I DO? The shipping weight is over 75lbs, I weigh about 147lbs so as I’m pulling the carton into my house to assemble it, I’m worried, can I push this sled? Well, I got it assembled that day and used it today, very happy to say I can RUN with the mower. LARGE wheels make it easy; the mower uses only one battery at a time (hence part of the shipping weight issue), it comes with a spare battery for extra-large jobs. Just a few things to know, I did a test cut (~10 feet) at the lowest setting and SHAVED the grass almost to its roots. Moved up to the 3-inch setting and it looks good. Only problem is getting it under solid objects like car bumpers. Also to stand it up, requires locking pins on either side of the push rail, unfortunately the right-side locking pin handle interferes with the wheel height handle when it is set at 3-inches so I need move the handle down (2-inch setting) and drop the wheels to set the locking pin. Minor issue, I just need to remember to reset the wheel height before cutting the grass next week. One neat thing, one handle sets ALL FOUR WHEELs (welcome to the 21st century!) unlike my old mower which required a height adjustment lever for each wheel. EASY START, good safety features especially with removing the battery. The charger has a cooling fan which is loud but not as annoying as a vacuum cleaner or a gas lawn mower. Overall, a great mower.

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.

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.

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.

Mower should be named Green Doesn'tworks. It's always in battery save mode running at an idle. not even strong enough to push the shortest blades of grass in the bag so it sprays grass all over the yard. then you have to re-mow the yard again (maybe even 3 times) to pick up all the grass it didn't push in the catcher. battery saver indeed. They should just add a "throttle" or speed lever or push button so I can choose how fast I want the mower to run. it bogs down so easily the cut is very uneven as well. Useless. This mower was a lot of money and I have a small yard, but after 3 seasons of trying to make this work I'm buying something else. What an e-Waste. I've not had any battery or charger issues - they are the components that work as designed. On the flip side I have their small snow blower and it's fantastic. Mower 1: Me: 0.

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.

Fonctionne bien et satisfait.

Works great and extra batteries can be used with my 80V green-works chainsaw
