3 reasons not to buy

  • Several reviews of the Worx Nitro 40V 20" lawn mower point out that the batteries might not last long enough to finish mowing larger yards in one go. The battery life of the Worx Nitro 40V 20" tends to drop even more when cutting through thick grass, which might mean you need to purchase extra batteries to ensure uninterrupted mowing. (27 reviews)

    • “The battery does drain much faster if you have to mow lots of thick grass though, so be aware of that. I had to buy an additional set of batteries to make sure I can mow my whole yard all in one go.”

    • “You need another two batteries to do a front and back yard of average size properly.”

    • “The 20v 4.0Ah batteries only did about 1/2 before they died.”

    • “First is the battery life. I have 1/4 acre and only got a little more than 1/3 of it done before the batteries died.”

    • “However, this lawn mower will not do the whole lawn in a single pass. In fact, if the grass is longer than usual due to not being able to get to it, I am looking at three passes with charging in-between to get the job done, and this is with brand new batteries.”

    • “After 6 months, the battery life is about 20 minutes.”

  • Users report that the electric mower has less power compared to gas mowers, which means that users need to keep up with their lawn more regularly to prevent the grass from becoming too thick for the mower to handle efficiently. (18 reviews)

    • “I was expecting to have significantly less power than a gas mower, and it does have less, but MAN does it get the job done. If a gas mower sits at 100% power, I would say this mower gives about 75% - 80%. What it translates to, is I just have to keep up with my lawn better and not let it get too thick, which I should do anyways.”

    • “If the grass has grown to a higher length, this thing will stop every few steps had it tried to cut the grass.”

    • “the horsepower was missing as the mower could not cut through the grass”

    • “This one does not have enough power to mow a really thick lawn”

    • “When grass is too high you need to set the mower higher or tilt upward on high patches.”

    • “If you try to walk faster, the cycle speed of the blades being lower, you’ll wind up with 'muppet grass' because you weren’t in that place quite long enough for the slower fan speed to cut all of the blades.”

    • “I can tell that the Worx lawn mower doesn't have the raw power of a 12 amp corded lawn mower”

    • “Does not handle anything very tall very well”

    • “The battery life can mow the entire yard as long as the grass isn't too tall--you definitely cannot go more than a week between mows.”

  • There are concerns about the durability of some plastic components on the mower. One user replaced the large plastic wing-nuts with metal bolts and nuts due to the design causing them to stick out and catch on obstacles. (9 reviews)

    • “I also have concerns about some of the plastic parts. Not sure how they’ll hold up over time.”

    • “Also the wheels are cheap and I work that will crack if it hits a curb or the side of the house as it brushes up against while mowing.”

    • “The side shoot came off 3 times during one mowing...needs a better connector.”

    • “I’ve only had it a few months, so it remains to be seen whether the material choices affect durability.”

    • “The metal deck is great compared to others with plastic but cheap plastic parts ruin it, especially the key.”

    • “It’s not built for rugged use.”

    • “with much of the other structure being sturdy plastic”

    • “Doesn't FEEL very sturdy, but I'm very happy with it.”

    • “Blade is chinesium.”

Bottom Line

The Worx Nitro 40V 20" mower is a hit for its light build, making it easy to push. Simple to put together and store, it's also quiet and gas-free, keeping maintenance easy. You can adjust the height for a custom cut and use the same batteries in other WORX tools. It mulches, bags, or side-discharges and recharges fast. However, battery life may falter in big yards or with thick grass, and it's less powerful than gas mowers. Some parts may be less durable, too.
