    Coming from a 26 yr old great gas mower, my biggest fear was power. The vast majority of video reviews really do not put electric mowers to the test. Well my fears are over. I setup my mower in less than 10 minutes. So great to push a button and instant on. My plush bluegrass lawn was wet. Mowed about 4 inches of height off of it. (I never let it get this out of control). Went right thru it without a whimper. And much more quiet than my old one. Now I will see how it does in the fall when I mulch leaves. Guessing it may be a bit slower than I’m used to but I have no fears about it doing the job.Only initial dings I would give this are the tires are just a bit narrower than I am used to. The clip that is supposed to secure the extension cord does not work with a 12 ga extension cord. (And do get a 12 ga if you want to protect the life of the motor. )The deck is steel which is outstanding. The mowing height adjustment is something that should be standard on every push behind. The mower is much lighter than I thought it would be. I always use the bag and this seemed to get the clippings even with the wet grass.Got this as a lightning prime day deal for $112. Unreal! Highly recommended if you are going with a corded mower.

    I was surprised how well it worked. Our grass had not been cut for at least 4 weeks and was thick and long. The mower had no problems getting through it as long as we were patient. When it hit the thick patches the blade slowed down. You do have to adjust and pull back to avoid shutting down the mower. It came pretty much assembled. All I had to do was attach the handle to the mower unit. We ordered a 100ft extension cord which can get in the way at times. Once you get a system down it becomes less annoying. You can adjust the height of the blade very easily on the side using the lever. I would prefer this electric mower over a gas mower or battery power mower just bc you don’t have to stop when you run out of gas or the battery runs out.

    I’ve had this mower for a little over a year now. It has served me and my lawn well.A little backstory about why i chose to go with an electric mower: My weekly chore growing up was having to cut the lawn at my parents (1/3 acre); my parents had a craftsman mower which had powered wheels and ran on gasoline. The powered wheels were nice to have because the backyard had a slight downward hill to it but I hated dealing with the gasoline. I disliked having to go refill (albeit occasionally) the gas can or getting gasoline on my hands while trying to fill the mower with gas. sometimes, I would spill a little gas while trying to fill the mower. Not a dealbreaker but it was just annoying.I bought a new house recently and this lawn is significantly smaller (1/8 acre) and pretty level so I decided to give this corded mower a try. Plus, my neighbor across the street, whose house was situated on a similarly sized plot, used an electric mower and he told me that he’s never had a problem.The toughest part about using a corded mower is figuring out the best way to maneuver/cut the lawn without having to constantly adjust the power cord. Once you get that down, you will enjoy using this mower – it’s got enough power to handle lawn mowing and even the occasional wayward branch. It’s easy to maneuver and switch between bagging/mulching. I like how the top half of the handle is held by easy-release brackets so that you can fold the top half of the push bar when you store the mower. The craftsman one my parents had did not have this feature and the mower took up much more space in their shed. It’s easy to adjust the height of the blade, there’s only one lever to adjust.Here’s a couple of tips for those considering doing the switch to electric mowers.1.Buy yourself a nice extension cord that will A) stand out from the lawn color and B) reach from the power source to the farthest corner of your lawn. I originally used the “outdoor” extension cord that i had for the christmas ornaments which was a dark green color. While I never had a mishap running over the cord, it took more effort trying to locate it as I was mowing the lawn. I switched to 50ft BRIGHT ORANGE power cord and have been using it ever since.2. Figure out the best way to mow based on how your lawn is situated and where the power source is. NOW MEMORIZE THAT PATTERN. It took a few mowing sessions for me to determine the best way to mow without having to constantly reposition the power cord but I’ve got it memorized now and I just follow that same pattern every time I mow. I don’t mind that its a corded mower one bit. Generally, its easiest to start at the point in the lawn that’s closest to the outlet and end at the furthest point from the lawn. I keep the cord between my two legs while I mow so that when I do the U turn at the edge of the lawn to do the next line of grass, the cord easily follows behind the mower.All in all, this is a great mower at a great price, its got all the power and features that one could need. It is a little quieter than a gas mower so for those of you go-getters who insist on mowing the lawn at 8am on Saturday when the rest of the world is sleeping in, your neighbors will thank you.

    This is a GREAT Lawnmower. I bought one in Aug. 2014 the year I retired and I am still using it here Apr. 2020. Lets see: my lot is approx 80′ X 170′, 80% grass that gets mowed 3-4 times per month from March to November (long season – I live in mid-south). You have to get used to maneuvering with a cord; but, you never have to buy gas or oil. So, whenever you want to mow, just plug it in and go.It’s not as heavy duty/powerful as the avg. gas mower but my lawn is just the average lawn; no week whacking, and since I do it most once every week in the summer and set the blade on a relatively low setting (1.5″ or so) it generally keeps the grass from getting too thick between mowings. Generally… once in a while when we’re having a lot of rain and I’m a day or two late the grass does get thick in one spot of maybe 25′ by 10′. Even that I can do without raising the blade height if I go slow and back up/go forward a bit as needed. If it stalls from too heavy grass I just release the power control, move it back and start again. (stalling the engine has been forgiving – not killed the motor yet – but I quickly cut the power when it binds). One advantage of the mower being of lighter construction than a gas mower is that if I bend the blade on a rock or edging timber I can just take it off, sledge hammer it straight again, sharpen it up a little and put it back on. (sort of like the bumpers on my old Toyota pickup ;)If I had it to do over again I would buy it again. As a matter of fact, I’ve had this thing almost 6 full years now and now that it’s getting old I’m glad to see they’re almost the same price as mine was back in 2014 if I need to buy one. Except this time I already have the cord.Doing the [ballpark] math: 2014: mower $149 + $95 for a better grade cord = $244/66mos = just under $4/mo to own the equipment PLUS add any electricity, which I haven’t noticed on the meter (not a lot). Compare to a gas mower which would have cost me avg $2.50 in gas each (1gal) mo X 46 months (excluding non-mowing winter) = $115 + $300 for a decent mower = $415/66mos = just over $6/mo over same time frame (except all of my metal mowers, in the past, have rotted out within 4 years due to the humidity down here so would have been more like $10/mo over 4 years for me, instead of almost 6).So, for me $4 vs. $10/mo (also, having no hassle getting gas once a month before I can start is a BIG PLUS to me). My choice: I’ll use electric. Not as powerful or easy to maneuver as gas mowing; but, once you get used to slinging the cord around, a heck of a lot cheaper, and energy use is almost non-existent. Just try NOT to run over the cord. (I’ve been very careful and not, but had 4-5 close calls in the past 5+years – there’s always electricians tape if you do – I haven’t been so lucky with my hedge trimmer cord :)) ). Hope this helps.Book version soon to be released! :))Mark

    Right out of the box the only assembly required is 4 hand torqued screws for the pushing arm. Two at the base and then two quick release clip style mid way up the arm. Note: For quick release make sure not to over tighten because during latching it, it could be too tight and break the latch. Besides that this is a BEAST! Example: My lawn was 10in + high and thick. Broke out the new lawn mower was about to mow and it down poured rain. Ugh…. Now I cant mow. 🙁 Wet and thick grass. I said lets test it. The deck is on medium high, and I was going to use the bagging option but wet grass would not be good for bagging so I took the bag off and forgot to up on the discharge option so I ended up doing mulching which is what will kill a mower with high grass. Nope not this thing. Some of the really thick areas it slowed it a bit but didn’t kill it. My old house I had a 3.5hp tractor mower with a 42 in deck and it has died repeatedly under these condition. This thing ate it up and kept asking for more. Yes I could not walk at full pace but I was only about half pace and it just tore through it. The only thing is watching the cord. Easy enough. Just work away from the plug with each pass. I never got near it. Plus MAKE SURE YOUR POWER CORD IS RATED FOR AT LEAST 12AMPS AT THE LENGTH OF YOUR CORD! Otherwise you are wasting your time. After I was done cutting a wet thick yard front and back I easily unplugged it and hosed it off to clean it up. Then stored it to dry. Yes it is a work horse. I would recommend if you are tired of gas tanks, oil stains, and pull starts. Lets not forget that cylinder engines dye easy if bogged down. Then you have to clear the debris and pull start it again. The electric will eat through with continuous power. Had it for year now and it still chews through it all. I just spray it all over after each use and put it away dripping wet. Still not upset about the purchase.

    I never like product reviews for recently purchased products as it takes time to learn about the product. That holds true with my purchase of this 12 amp, 20″ mower that I purchased off of Amazon May 8, 2017. My wife and I live on 35 acres and have had our share of lawnmowers over our 63 years. This lawnmower is not for cutting a large area. It is not suitable for fields, bush-hogging or clearing land. We use this lawnmower for an area around the house, pool and deck for what I would say is an average home yard size. 1/2 acre. It can handle deep grass without bogging down. The type of spring grass growth that you get when you can’t mow because it hasn’t stopped raining. This was one of my biggest concerns and this mower passes the tall grass test. Two, the electrical cord. I love the electric motor and I hate the cord. But I love the mower more than I dislike having to use a cord. Get over it! You won’t smell like gas and exhaust when you are done. I’ve considered buying a full battery version but I am hesitant for the same reasons. Tall grass, not enough power to get through the deep stuff, etc. So, my electric Greenworks 12 amp 20″ mower is 3 years old May 8th and it runs like new and I still love it! Best of luck cutting.

    Great lawnmower. Plenty of power using a heavy duty 12 gauge extension cord. Gotta go slow over tall grass, & make sure it’s dry after rain or watering. Very convenient & easy for 69 year old semi-disabled female (5’5″ tall 168 lbs) to operate. Just take great care to keep the extension cord out of mowing path, & away from tangling in your feet. Be vigilant about this & just mow away!…without the need to pull start & without the need for a man to get it going. Just push the button, pull up on the handle lever & off you go. No worries…in a jiffy, your lawn is easily mowed & beautiful again. 🙂 jlp

    I bought this to replace a riding mower which was too big for our yard and I did not feel comfortable on it. Took about 10 minutes to get used to using it, but becsuse I never really had to mow before, getting used to the cord was not difficult. This machine is light weight, cuts well, and very easy to operate. I have a bad back but need to get as much exercise as possible and with this machine I feel very comfortable working with it and getting the exercise I need. I was going to hire someone to do my yardwork but I am certainly happy I did not do that. Husband always did it all, but recently passed, and I am 67 years young so with that bring said I would highly recommend this lawn mower.

    I’m 5’2″, 70 years old and in average shape (I don’t work out). I’m mowing slightly less than a 1/4 acre yard with several trees. This mower has been surprisingly easy. I am so happy. It’s much easier to maneuver than my self propelled gas Toro. I can actually push it with one hand on much of my lawn. WOW.Cord management is the short learning curve. The issue I have isn’t so much not running over the cord, but ensuring the cord follows easily. It’s very very heavy. If you do as suggested and start mowing closest to the electrical outlet, then go back and forth (parallel) from the outlet, it works fine.I’m very very happy with this mower. Tight turn radius, again much much better than my Toro. I cut weekly so no tall grass to deal with. I rarely ever use a bagger so I can’t tell you about that.Unpacking and assembly took minutes. I opened the box, then cut the seams if the box and “drove” my mower out on to the cardboard drive. Removed a couple of pieces of packing, raise the handle, tightened screws and plug it in.I have turned dreaded lawn mowing into a Zen moment. I know, call me crazy, but it works. And the extra exercise doesn’t hurt either.

    I bought this mower for a friend, whose spouse was temporarily disabled and unable to do yard work. She loves it for its light weight and the great job it does on the lawn. She caught on to cord management very quickly. Lovely little machine! How did I know to get it? I’ll tell you.Back in 2009 I decided to try an electric mower after my old push mower burned out. I got the 20-inch model even though the guides said that my 1/3 acre lot was too much grass for this kind of machine. Well I was used to trudging behind a 21 inch mower so I didn’t see how a 20 inch would be all that different if the cord would reach. The mower I chose (a Task Force purchased at a local chain store) is identical in all but styling details to the GreenWorks 25022. Even the wheels are the same. It has the same EZ height adjuster, same amperage, everything. It probably was built at the same Chinese factory. Right out of the box, the mower worked very well. I needed 150 ft. of heavy cord to get to every place on my lawn, which is extreme but did not cause me any problems. I suspect my local utility is supplying power closer to 125 volts than the minimum 110.At the same time I bought this mower, I also purchased a 21-inch gas-powered Troy-bilt as a backup. I quickly came to prefer the electric for its light weight and ease of maintenance. Comparing the two, the gas mower has more power to plow through overgrown or damp grass. The electric can handle overgrown grass, but you have to slow down and the side discharge will clog occasionally. If I had to cut overgrown grass with the electric, I would raise the deck to the highest setting and then cut it again at standard height the next day. It takes me about an hour and a half to cut my lawn with the gas mower, and by the end I’m worn out. The electric takes me about two hours, but at the end I’m still fresh because it’s SO much easier to push.My brilliant repair #1:Early in the second season one day, I was happily cutting away when the mower lost power and then quit running. Kicking the tires did not revive it, so I put it away after calling it a hunk a junk and finished the season with my new gas mower. I used the gas mower exclusively the next year also, but in the spring of 2012 I took the cover off and gave the electric motor a hard look. A gap had opened up between one of the brushes and the armature, causing a spark to arc across the gap and deposit a layer of carbon on the armature. When the carbon got thick enough the motor wouldn’t run any more. I found the owner’s manual, called the parts source, and ordered new brushes. They installed easily, and the motor has run perfectly ever since.My brilliant repair #2In the 2013 season the safety switch started popping loose and shutting down the mower. I carefully disassembled the switch, found nothing broken or worn, and carefully reassembled it. Since then it’s worked perfectly for four years. Just recently it’s started doing it again, occasionally, but this time I doubt if taking it apart will fix it. Parts wear out.Update 7/28/2017: My less than brilliant third repair. As expected, the safety switch continued to pop loose. I opened the case and saw that some plastic bolsters around the kill button had broken off leaving the button with too much freedom of movement. I bought a simple toggle switch (overpriced at $9.50) and installed it in place of the original. Losing the dead-man switch was not a concern to me because I was a grown man before those things were required. However, I also lost the blade brake. Without it, after power shut-off the blade continues to spin like the flywheel it is for at least ten seconds. That is dangerous, so kids, don’t do this repair. I’m going to get a second switch to reinstate the blade brake. It will be completely manual, but better than nothing.As others have mentioned, the choice of cord is critical. Pick one too small for the job, and you’ll burn up the rectifier. I think the rectifier is also sensitive to hard use. Keep the RPMs up, don’t lug it down in thick grass. A sharp blade will slice through the grass more easily, without bogging down. The blade is easily removed, and can be sharpened with no trouble if you have something to clamp it and a 10 or 12 inch flat mill (aka “flat bastard”) file. I’m sure YouTube has videos on how to do it.Others have also mentioned that the motor compartment is not sealed. Grass and leaves and trash will accumulate in there and potentially cause trouble if not cleaned out from time to time. This service involves backing out the four bolts that hold the plastic cover in place. After removing the cover several times, I have stripped the heads of the soft bolts and can no longer get them out. The buildup of trash may soon cause me to need Brilliant Repair #3; or more likely I’ll just buy a new GreenWorks. If you want your mower to last, replace those soft factory bolts with hardened stainless steel versions, and keep the threads lubricated.One other thing I love about this mower: You can flip it upside down to clean the deck. I promise the gas and oil won’t run out of it!
