  • Makes Lawncare Easy
Size: 16" (4.0Ah)
March 20, 2025: The mower is still working like a champ. First cutting of the year is done. The Greenworks weedeater I got last year is also working perfectly, right along with the electric pressure-washer I bought 6 years ago. I saved over $1600 in lawncare expenses & home maintenance projects last year. **I was not paid for this review** July 25, 2024: Sharing a little trouble-shooting info. If the battery gets overheated, the mower will just stop. I had this happen & I thought the battery needed recharging. If you pop the battery into the charger this way, you'll get the red indicator light. The battery simply needs to cool down first & then it will work again. I'm now storing the battery inside the house, not out in my garage in 90+° temps. Overheating it, as well as keeping it sitting on the charger 24/7, will eventually deplete it's capacity to hold a charge. Hope this helps. Update #2: The mower powered through a huge area of thick, knee-high grass in the backyard. First time cutting it this year. I also did the front at 7am & the grass was wet. Mower ran like a champ. After removing the battery, I tipped the mower on its side, cleaned the underside with a small putty knife, gently rinsed it with the garden hose & let it dry. Mower still works great. Update #1: Mower continues to perform very well. The battery is tricky to remove. It has a release button on it that has to be pressed down at the same time as it's pulled out. I put the handle of the mower up against the siding of my house & it keeps the mower from rolling as I get the battery out. OG Review: First time I've ever tried out any kind of battery operated yard equipment. I'm tired of paying the lawn guy to cut my entire yard when it's only the front area that needs to be consistently mowed. This mower arrived brand new in the box. I had trouble with the handle assembly & the two sets of cam locks because they don't tighten and clamp down the easiest. That took a few tries. The battery slides into the charger which blinks green when charging, and then stays solid green when charged. The battery clicks into the top of mower much the same way. The battery has a power indicator on it - press the small button on the end of the battery and there are 4 lights that show the amount of charge. Starting the mower is sooo easy. It takes about ~5 seconds to get it powered on & instructions on how to do so are printed on the mower by the starter button. If you need to stop the mower, release the bar. Stopping & starting the mower up a few times was no problem for me. The lever on the deck that adjusts the mower height moves easily and locks firmly into place. My first test run of this mower went well. I did my entire front yard and around the side of my house in 35-40 minutes with a battery that was still going strong. The mower will speed up if the grass is thicker & runs slower for less dense areas. I'm not using the grass catcher, so no idea how that hooks on or performs. What I really like is how lightweight the mower is and how quietly it runs. I doubt my neighbors across the street could even hear it. One important piece of info that I'll pass along. After watching a YT tutorial and review on this mower, it was recommended not to keep the battery sitting in the charger 24/7. Charge the battery just before use, recharge it again after and then take it off the charger & store it separately. Doing so extendss the life of the battery. Overall impression on this mower: Easy startup, runs super quiet, it's lightweight so that you hardly exert any energy pushing it along and it has a long-lasting battery charge. For me, this mower will pay for itself in just 3 uses (I got it on sale) and I'm excited to finally be able to cut back on yard expenses. I'm also thrilled that I don't have to be bothered with the fuss of fueling & and winterizing a gas-powered piece of equipment. ... show more

  • Lightweight - no gas smells - really powerful !! LOVE IT !!
Size: 16" (4.0Ah)
I was quite amazed at how well this cordless mower performed, it greatly exceeded our expectations. I have a Briggs and Stratton gas mower that I struggle with every year - no more!! Plastic carburetor needs replacing every year - garbage! I've heard so many good things about these mowers that I bought one from Amazon (next day delivery) and just got it today. We don't cut our own lawn anymore (1 acre) but I need something for when the backyard lawn gets too long and we're having family over. Some of the lawn was like 8" long today! This little dynamo mower didn't slow down or hesitate at all. I think it actually senses taller thicker grass and I hear the speed actually increase to compensate. It's super easy to start, light as a feather to push (glad I didn't get self-propelled - you don't need it!!). I had serious doubts, but my wife and I are very impressed ! The grass catcher is a good size and so easy to empty. Hats off to them! ... show more

  • Another step forward to going all “green’” with yard work.
Size: 21" Mower (2 x 4.0Ah)
Had a battery operated blower for several years now, bought a Greenworks weed eater, which works just as well as my gas operated weed eater, and now, purchased this Greenworks lawn mower. I always read the reviews of products I’m interested in buying and noticed when reading reviews of different types of Greenworks mowers, they were all the same reviews. I was confused as to which mower the purchaser was reviewing or talking about. So I want to make clear that this review is for the 21” steel deck, single blade, self-propelled mower that comes with 2 - 40V batteries and a charger. Right out of the box, it comes pretty much assembled already, you just have to connect the upper part of the push handle, very simple. The mower seems to be of good quality and well built. This mower has 2 ports for the batteries to go into and it will use power from one battery until it runs out of juice, then automatically jumps over to the other battery. I had no problems there, it worked like it should. The mower itself is pretty light compared to my gas powered mower. I had no problem turning or maneuvering the mower. Now, the self-propelled action of the mower is different than what I’m used to. With this mower, you push the handle down into the lower portion of the handle, like a shock or pogo stick. Seems like it’s gonna take some getting used to. I really don’t like the way this operates. I cut the majority of my yard without the self-propel on. As far as the cut goes, my back yard was pretty high, haven’t cut it in 2 and a half weeks and the mower cut through it just fine. I did not use the catch bag or mulch the grass. I used the side shoot accessory. The mower did a great job on the yard, although it did stop twice while cutting. I’m not sure if it was because of the built up wet grass under the deck, or if I let the safety bar loose while pushing, but I just re-started it, it fired right up and I continued cutting. I cut for about 45 minutes, and had about 50 to 60% of one battery left. I like getting away from the gas and oil, the smells, and the noise. I believe this will be a good transition for me. The mower is pretty quiet, which is deceiving, because you think it doesn’t have the power you need, but the power is surprising. I’m kinda looking forward to next weeks cut. ... show more

  • FANTASTIC AWESOME ETC. Fantastically durable, battery life infinite, etc.
Size: 16" (4.0Ah)
FANTASTIC. AWESOME. ETC. Oops, excuse me. Amazon promised to deliver it by last Saturday (2 days ago), but it STILL hasn't arrived. My fulsome praise was a bit premature. Maybe it will arrive today, but we don't know that yet. Nor whether it will live up to my praise as being a Fantastic product. (Spent almost an hour on phone with Amazon, late Saturday night, but nothing was resolved). Still, it's obvious that it is antastically durable, mulches like a dream, that battery life is super-impressive, cut quality supreme, and is very, very fast! And assembles itself! ... show more
