    • “it increases the power and you hear the mower speed up”

    • “If you are cutting very thick grass or cutting more than two inches off of your grass (especially in "mulch" mode), the motor will sense the slowdown (which you'll hear) and it will speed up.”

    • “It has a cool feature where it will rev up when it senses a patch of thick grass.”

5 reasons not to buy

  • Some reviews of the Greenworks 40V 16" mower mentioned that it may not be ideally suited for larger or denser lawns, particularly if the grass has been left to grow for an extended period beyond two weeks. In such situations, this mower might require more power to cut through the thicker grass, potentially leading to quicker battery drainage. (27 reviews)

    • “It takes me about 4 charges to do my half acre if it is a bit dense (week and a quarter or so).”

    • “The electric mower definitely did not have as much power as the gas mower, and the 16" width meant I had to make more passes.”

    • “I definitely like it, but if I had any bigger of a lot, I would like to upgrade to a bigger deck and possibly an 80V system.”

    • “Small cutting path (I highly recommend going up to the 24" or larger if possible)”

    • “I do wish I had bought a slightly wider version because our backyard takes the full battery to mow”

    • “It took me three charges to do my 1-acre lot.”

    • “If you are cutting very thick grass or cutting more than two inches off of your grass (especially in "mulch" mode), the motor will sense the slowdown (which you'll hear) and it will speed up.”

    • “Don't skimp and go for the smaller model unless you have a VERY small yard. ... I needed 4 fully charged batteries to get through my 1/6 acre yard with the 16" model.”

    • “Now with a much larger yard this 16" model is too small, too weak, and too basic to tackle my growing needs.”

  • The mower is not self-propelled, which could be a downside for some users, especially when mowing larger yards or slopes. (16 reviews)

    • “It is very light and easy to handle even though it's not self-propelled.”

    • “His is a little bigger and has the self-propelled feature, and this one doesn’t but I don’t mind because our lawn is a smaller size”

    • “This thing is light. It’s easy to push.”

    • “Due to it being mainly plastic (lightweight), you literally can push it with one hand.”

    • “It's lighter and easier to push than a standard gas giant”

    • “Even though it does not help you push forward I still gave it 5 stars for durability.”

    • “It weighs next to nothing. I felt like I was pushing a toy vacuum I had when I was a kid- easier than pushing my Dyson”

    • “Super light - I don't miss the self propelled feature (my lawn is perfectly flat)”

    • “Pushing it around my front yard gives my shoulders a workout”

    • “Easy to move around even without a drive function because it is so light.”

  • A big drawback people mention is the cost of extra or replacement batteries. For those with bigger yards, more batteries might be needed, which can add up to a lot of extra cost. (15 reviews)

    • “If you have a good size yard and this would be your only mower you would need spare batteries which are expensive.”

    • “That leaves me with a dilemma, buy a new (very pricey) battery for my perfectly good but aging mower in the hopes it will last another 9 years, or upgrade to an 80v mower.”

    • “You'll just end up spending more when whatever inferior battery type you went with dies, and you end up buying the expensive lithium one anyway.”

    • “As a bit of advice however, if your yard normally takes more than an hour to cut, you should consider buying an 40V additional battery as a time saver.”

    • “But the thought of purchasing another battery (Greenworks brand) is an additional $100.”

    • “The battery only lasts about 40 minutes so if you have a large lot, you'll want more batteries”

    • “I was just getting time to change the batteries again and had to weigh a couple hundred dollars for batteries (the good ones anyway)”

    • “I will be purchasing another battery so mowing the backyard doesn't take 4 or 5 hours.”

    • “I may need to buy an extra one to fully cut my entire yard.”

    • “I also ordered a second battery so I can keep one charged at all time”

    • “If you are doing a large yard buy a second battery so you can finish the yard while you are in the mowing mood”

    • “I like this lawnmower though and I plan on buying an extra battery so we don’t have to wait for the battery to charge halfway into mowing.”

    • “Of course, I may decide to buy an extra battery, so that when I want to continue working I can.”

    • “I didn't have the money for a extra battery at the time of purchase.”

  • The grass clipping bag is called 'laughably small,' meaning it's not good for bigger lawns because it would need to be emptied often. This might make the mower less practical for people who like to bag their clippings. (13 reviews)

    • “The grass clipping bag is laughably small. I would NOT want to bag much more a town house sized lawn, for fear I'd wear my shoes out with the amount of walking around it'd take to empty it so many times.”

    • “The grass catching bag fills very quickly and only allows you to empty it from the narrow end making it difficult to empty.”

    • “The grass catcher fills up fast but is easy to remove and hook back up so it's a quick action.”

    • “Grass catcher is very small.”

    • “Bag is small so will have to empty more often compared to the standard gas mower”

    • “It had been about a month since I last mowed, so I had to empty the grass catcher three times total.”

    • “Small grass catcher.”

  • The Greenworks 40V 16" lawn mower requires a specific 'key' (an electrical jumper) to operate. If this key is misplaced, obtaining a replacement could become challenging as time passes, potentially causing inconvenience for users of this model. (1 review)

    • “It requires this little "key" (electric jumper is more accurate) to operate. I would NOT want to lose that.”

Bottom Line

The Greenworks 40V 16" is a user-friendly electric mower ideal for small to mid-sized yards. It's lightweight, easy to maneuver, and assembly is a breeze. Its battery is long-lasting and interchangeable with other Greenworks tools. Running quietly and requiring minimal maintenance, it's an eco-smart pick that stores compactly. It's not great for large or hilly lawns due to the non-self-propelling design and small clipping bag. Extra batteries can be pricey, but overall, a durable choice for regular lawn care.
