Excellent electric mower. The battery has a long life. I am able to do two yards one is 175 ft long x 80 feet wide ( front and back) the other is 69 ft x75 ft (front and back) and I still have battery to spare. I love how light it is and folds and unfolds easily. It can go through tall grass and even handles thick grass. Only draw back is the deck size is a bit small. This mower is definitely worth the price. It is easy to push even on slopes (nothing too steep). It can handle mulching leaves as well. I happy I made the switch from gas to electric.

Ok so let me start with probably useless information but please read on if you’re curious . I have always been a huge fantasy and sci fi fan - so as technology advances and things just get cooler I anticipate seeing how they work . So here we go with the actual valuable information . I had a name brand gas mower last season , hit a tie down strap that was cemented in the ground . Bent blade,the whole shaft , cracked the motor. =Done So I was in the market - I found this , read some reviews like everyone else . I liked what I seen and ordered it . Now here is where I was blown away, first and foremost strait out the box it was lightweight as described , handle makes it easy to handle , lift , and control - the weight is balanced well . My overall first honest opinion and reaction -wow! But at the same time I said this is gonna mow the yard , feels like the little tikes mower I used as a kid like a toy . It was packaged nicely and the level of support and attention to the packaging mattered to me because it being lightweight and possibly being thrown around , or tossed around during shipping . So 5-star there . And getting it out of the box , it was literally 4 handles. That are click in place by the way . Like literally can not be any easier . So popped the handle up into place check the stability and shakiness in the handle and the base - there was none, thanks to the sleek design . Firm and no play , instant control . Now to the battery and the charging . Again packaged nicely , I had no worry about a defected battery based off of appearance after opening it . I put it on the charger for the first charge - and here is the part you will have to choose , I did not charge it the recommended hours as most people don’t but it does matter with some devices and products . I charged it for 3 hours and at that point it was fully charged . The next day was the day to put it in action . So put the batter in and let me tell you Getting it started literally push of a button , no pulling a cord , no repeated cranking , pushed one time , pulled handle down - there it went , running a quiet humming noise, almost nothing to hear over . The sound is literally none . You will be able to hear every lyric to every song your listening to lolbvs . So I like that . It is very quiet while running . 5-star there as well . Now to the part that matters - mowing , how does it mow ? Well I will tell you I have a small yard which is why I got the model I did. The -1 hour run time is accurate so far . By the time I am done mowing it literally is on the last bar of green . However it does not run differently as the power is running low , it is consistent cutting until the battery dies , the power actually revs up when it needs to and idles back down when not needed and normal . So this is a well built machine . And I actually recorded a video of a section next to my yard that was overgrown . I’m not sure about the sound but I hope it’s to where you can hear it run while working hard . The video below is right before I quit for the day so it was at the last green bar at this point . And it didnt skip a beat . Kept working as well as it had been . So my final thoughts on this product - truly impressive . I have worked construction for over 20 years , used multiple types of tools in my life . And have used even a the olde manual mower with 2 wheels and blades , and I’ve used gas mowers , self propelled , riders , zero turns . This is an impressive machine . If you have a small yard , want a nice clean smooth cut . Easy to handle . Don’t want to worry about gas or gas prices when it’s time to mow . This is definitely a product you should invest in . I say that with absolute confidence. This is a purchase I’m glad I made and invested in . I hope this helps , there is a lot of doubt surrounding electronic tools , vehicles, etc … but the technology behind it now days is very different than what they were so the products them selves are very different . ( i have used it for 5 mows at the point in the video as well ) 5-star product all around .

Nice light weight lawn mower. I was hesitant at first going from a gas one but I am happy with doing so. Mower is quiet and easy to push. The only downside fault is the start is a little tricky at first but once you get it, it starts like a charm. The battery is a little tricky to pull out but it comes out once you get it moving, I would say I love it. Great for little lawns.

UPDATE: I'm going to bump my review up to 4 STARS (from 3). Yes, it was a weak on my first test because, as I said in the review below, the grass was wet and had been allowed to get way too long and thick - conditions that would even cause the gas mower a little hesitation (just not as much). Today was my second use with the lawn being in "typical" condition. The mower was delight - easy to use, cut neatly and quickly, and this time I put the grass catcher on correctly (!) and it worked BEAUTIFULLY, easily catching 90% of the trimmings. And I don't smell like gas. If it holds up, this mower will be a great purchase... as long as I avoid wet, month-long growth! UPDATE to the UPDATE: After a full season with this mower, I can heartily recommend it. Mowing is a breeze and it has performed flawlessly. Even my wife and daughter who had refused to mow the lawns now no longer have an excuse(!) and they really like it. Original review: PROS: * Set up was easy, just unfold the arms and tighten them down, charge the battery and insert. Insert the catch bag. * Maneuvers more easily than a heavy gas mower * Lithium-ion batteries should last longer and are lighter than lead-acid * No gas! No going to the gas station! Nor you do you smell like exhaust afterwards - just a little grassy! * Charges in 1 to 2 hours * Battery holds up pretty well - no cords! (really think about how annoying a cord would be going back and forth) * FAR quieter than gas CONS: * Definitely weaker than a gas engine * A bit pricey * Long term durability in question * Takes longer because footprint is smaller, and you have to go slower in tough conditions * Not good for huge lawns NEITHER HERE NOR THERE: * Mower is relatively light - half the weight of a conventional gas mower, but also mostly plastic. There's little to rust, but I wonder how durable it will be, especially those kinda cheap wheels that love to get jammed between the lawn and the cement edges. * Looks ridiculous. Like a kiddie version of a street racer from Fast and Furious. It's almost embarrassing to push this thing around the front yard. ;) Then again, you might think it looks pretty cool. Okay, so how well does it work? Today was kind of "worst case". The lawn was longer than normal (because the gas mower broke and it took me a week to get around to ordering this replacement) AND about 50% of the lawn was thick and QUITE WET. These are challenging conditions to be sure, but the gas mower would have handled them with only minor problem. This little guy really struggled with the longer, wetter grass. I had to go slower, and frequently back-off or lift off to keep from bogging down the motor. It quit on me once, but started right up again. I think I could have done the front lawn in about 5 minutes using the gas mower, but this took me about 12 minutes (UPDATE: second time, in normal conditions, it took about 7 minutes). With these conditions, I really questioned whether the battery was going to hold out for the 25 minutes or so that it would take to do my <1000 square feet of lawn, but it did. It still reported about a one-third charge upon completion. In the patches of lawn that were neither especially long, thick or wet, the mower flew over them with absolute ease. SO... if you frequently encounter EXTREME conditions (extra long, thick or wet grass) I'd advise you to stick with gas. This one will get the job done, but there's just no comparison to the power of an internal combustion engine. BUT... if you have a modestly sized lawn, and do not mow it wet and crazy long, then I think you will LOVE this mower. I'm looking forward to trying it again under better conditions so I can confirm this and report back to you.

I am really impressed with this Greenworks 40V cordless lawn mower. It was easy to assemble right out of the box, and the battery lasted long enough to mow my entire yard on a single charge. I love not having to deal with gas, oil, or extension cords. The mower is lightweight and easy to push, even around tight corners and flower beds. It cuts evenly and leaves my lawn looking clean and well maintained. The height adjustment is simple to use, and the grass collection bag works great. this is a great mower for small to medium-sized yards, and I would definitely recommend it.

Got this, unboxed, assembled, charged and did a trial mow. Unbox and assembly easy. See YouTube for videos.. My model was different from item described on Amazon, where I bought it, and the videos on YT. Mine does not have the button activated, spring driven platform for mowing height. Instead, it has a mechanical lever with several height options. I prefer this arrangement, potentially fewer future issues. Also, the mulch plug is different and not intuitive. There are apparently at least three versions of this plug, four if you count the one on the Amazon video. I found a YT video that shows how to insert these three types. Battery was nearly or fully charged out of the box. Charger level feature is not intuitive and the manual sucks. The charge level lights are not on by default, only when depressing the green button above them. The battery performed well. I have a 40' x 120' lot about half of which is covered by the house, driveway, garage, tool shed and patio. So about 2400 square feet of lawn. I mowed about 2/3 of that and there seems to be plenty of battery left. I will finish* the rest tomorrow and see if one battery charge can handle that, I will be more than satisfied. *Was able to finish my yard and still had some juice (one green light) left. Update: I have two houses and this mower was easy to put in the back seat of my Ford Focus and transport 45 miles. I had a pinched nerve in my neck at the time, loss of strength in my dominant hand at the time, in a lot of pain, and was still able to easily transport and use it at my second home. About the same size yard at my second home but much less level and it still worked great. Bought a second one and retiring my gas mower and replacing my corded tools with lithium battery Worx tools, weed wacker, hedge trimmer, etc. Will update review in a year, or so.

LOVE this mower. Easy to assemble. Not heavy when having to pick up. Turns on easy and quickly. Easy to push, cuts great and even. Bag attachment is perfect. You can tell when full as the mower is a little heavier to push. I have used it four times and each time I was tired before it gave out of battery. It’s a keeper. Especially because there is no vibration and my husband is able to use it. His kidney stones get jostled with the gas powered mower…. Yay for battery power!

This Cuts Deep! Note this is for the 16" 40V 4 amp mower. So, first time caller line for electric mowers! I'm rating this right out of the gate four out of five stars because, first time. You can't go rating a lawnmower 5/5 on your first run, it's nonsensical to do so. Anyway, I've NEVER used an electric mower before so this felt a little odd, but not overly so. It sounds like a mower, just like... two houses down when its right in your face. And thank god it's mostly plastic (more on that in a bit) because it makes it really easy to throw it around. I was one arming it quite a lot, jerking it around to catch spots I missed and basically really happy I didn't spend more for a self propelled, which would have been silly. This thing doesn't weigh much at all, you can lift it one armed by the handle and everything. The experience was pretty great. We're deep in our dry season and it's getting quite hot here so the grass is pretty sparse, not a challenge for it. BUT, the ditch was really overgrown so I had to do about 30' of 1' tall thick weeds and grass. I noticed that when it got loaded down, the RPMs went up about double to compensate. That's a neat touch. It cut right through that mess like butter, and took out some other thick, heavy weeds like any gas mower would, no problem. And it was silly easy to push, really no big deal. As I said, I took to one arming it and jerking it back and forth like a toy, and my dominant arm has a tendon injury near the elbow so I should be in a lot of pain from doing that but I'm really not. It's a pleasure to use, does great. The area I cut was just about 3000 sq feet, mostly sparse grass with the really thick patch in the ditch about 30' x 5', and a couple other small patches of thick weeds. I cut the whole thing set to mid height, I guess 3"? The battery dropped from full charge to about half, according to just the four LEDs on it. Maybe the thick overgrown stuff took it down but that's probably something to keep in mind if you're looking at a big yard to cut. Maybe go ahead and grab an aftermarket battery just to not have delays on bigger jobs? I'm getting one of their 40V weed eaters with a 2 amp battery so I'll have that as well eventually. The battery itself was pleasantly warm after I got done. Not hot, just warm. Note, the blade housing area IS PLASTIC, so I would expect wear to happen over time, especially with like rocks or whatever hitting it occasionally. You also probably don't want to scrape too hard when cleaning it. Me, I'd use a scotchbrite I think. I didn't need to clean it because this is our dry season and only the front yard had any substantial grass, so it's really just dusted with grass scum underneath. Lots of dust on the top but I don't have a hose yet so I'll let that be for now. Thoughts of the day? I'm happy enough with it. I didn't want to get a mower in the first place but my landlord dropped the lawn services off my lease so I had to do something and didn't want to get into gas mowers for a number of reasons. And my yard isn't huge, just 3500 square feet total, so there's good and then there's overkill. This is good category. Big LiPo batteries are expensive, so be ready for that when it eventually dies, but... should get some decent use out of it before that time comes and aftermarket batteries are substantially cheaper as long as you get a good one and not some POS that is rated for the moon and stars but delivers half dead swill instead. Also, here's a cheery thought - these produce power full time right out the spring terminals (2x +, 2x -) so you can do whatever you wanna do with that. I envision a nice 3A regulator assembly addon spitting out whatever voltage I'd like at that moment to power whatever I may need. Why not? 40V x 4 amp is pretty big power density, shame to let it sit there unused between mowings. Would also be neat to see if it can jump start a car, lol. Not set up for that, but I can see it being a thing in a pinch. Just don't let it crater or sit there at full capacity because neither is a happy space for LiPos. Keep it tailed off about mid if you're not going to use it. Speaking of which, after this first mowing the output is sitting at about 37.2V. I didn't think to measure it at full charge, but I can come back to that and give y'all the picky details. So yep, I like it. I think I'll like it even more when I have the matching weed eater plus battery. Summary: It's light, it's effective, it cuts nicely, its very easy to push around, mulches the crap out of the thick stuff, and I expect it to be easy to maintain. If it doesn't die in untimely fashion, I'll come back and bump it to five stars. Could do a lot worse. :-) NR417
