    • “The battery takes a while to charge when fully empty (a couple hours maybe, I wasn't really paying attention, but it didn't seem terribly long), but it then runs the mower for a long time. I can easily mow both my front and back lawns with charge left over on what I guess is a fairly standard city lot size.”

    • “My yard is so small, I can get it done on 1/2 the battery charge.”

    • “I definitely like not having to winterize or rebuild the carb of the gas mower every season.”

    • “It's electric, so you have just one moving part other than the blade. The blade is the only thing requiring maintenance. Say goodbye to winterization of your mower. Say goodbye to trying to hunt down ethanol free gas that won't ruin your mower's gas tank or carburetor.”

    • “The only maintenance it’s needed was a blade sharpening every other year and it’s worked flawlessly for, by my rough math, about 300 mowing sessions.”

    • “It is virtually maintenance free and easily folds down for compact storage.”

    • “I love NOT having to ever mess anymore with gas or oil or primer buttons or hurting my side or bad shoulder by pulling a cord!!”

    • “Just the fact that I can pull this thing out of the basement in the spring, pop in the battery, push the starter and get it going without having to pull my arm off and drag it into the shop every year makes it so worth it.”

3 reasons not to buy

  • The Greenworks 60V 21” Lawn Mower has garnered some user feedback regarding battery charging issues, with a few customers also noting difficulties in removing the battery from the mower. (15 reviews)

    • “I put the battery on charge and I noticed the red light was flashing. It didn't charge.”

    • “The most difficult aspect of the mower is removing the battery.”

    • “After I got the cowling reattached (had to force the screws to align with the holes) then I found I could not remove the battery. Forcing the screws racked the cowling such that the battery was stuck.”

    • “Only drawback is the battery takes kinda long to charge, and runs about 30-35 min”

    • “The first time I inserted the battery and tried removing it, it wouldn't come out. I pulled it (after pressing the push clip) as hard as I could but it wouldn't come out.”

    • “Charging the battery takes a while (90 - 120 minutes), so you'd do well to pick up a spare.”

    • “The battery encasement is extremely small and the batter slides in from the top, so there is very little room to get a grip on the battery, push the lever down, then pull the battery up and out. Plus, I have to hold the wheels with one foot so the mower doesn't move while I'm struggling with the battery!”

    • “The battery life was short I have a pretty standard lawn, live in the middle of my block. I only got 1/2 way thru when it died.”

    • “battery only last 15-20 min. Can’t do much in such a short time.”

    • “My original battery and the new battery only lasted just shy of 15 minutes per battery. I needed 4 fully charged batteries to get through my 1/6 acre yard with the 16" model.”

    • “It took 2 hours to charge the battery. After about 45 minutes of use, I still had 1 of 4 bars left on the battery.”

    • “I could only get half the back yard mowed with one charge. THis means it would take one hour to charge the battery and almost one to mow. When the battery dies you have to wait for a cool down period then charge then mow again.”

    • “Batter not working. I return it.”

  • The mower struggles with long, thick, or wet grass and requires going slower or making multiple passes, which may not compare well with gas mowers. (14 reviews)

    • “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.”

    • “I did have to do multiple passes to get it all clean and neatly cut, but I've had to do that with a gas mower too.”

    • “Ended up returning mower because the Bermuda grass was more than it could handle even @ the highest height setting.”

    • “If I mow slightly damp grass it will clump around the blades”

    • “Like a vacuum cleaner, you end up having to go over a few spots a couple of times”

    • “You may need to slow down your cutting speed from a gas powered unit”

    • “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. This drains your battery /much/ faster.”

    • “The first time I used it the grass was wet and I took off about two inches. It didn't do a great job”

    • “It will stall out when faced with a patch of thick grass, this in turn causes the battery to run down EXTREMELY quickly.”

    • “NO Power Battery runs for 5-10 minutes max, couldn't get through my first mowing of a dry, 2.5 inch 600sq ft lawn even on 2 charges”

    • “The mower tends to leave clumps of grass clippings unmulched, even in areas where the grass isn't very high and is certainly not wet. I've had to go over areas 2-3 times in order to get rid of most of them.”

  • While the mower is lightweight, there are questions regarding the long-term durability of the plastic construction and components such as the wheels. (14 reviews)

    • “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.”

    • “The only negative thing I can say about it is it seems a little chintzy.”

    • “since it is all plastic”

    • “It was a bit tough to get the clamps in place that are supposed to help it fold down.”

    • “Upon close inspection, I found three of the screws that hold the top cowling (covering the motor) to be missing. I expected to be able to simply reinstall them but the plastic cowling had to be forced (using two people) to get it to allow the screws to align with their holes.”

    • “Whole thing is plastic so don’t expect longevity”

    • “seems like some brushes come a loose and you have to remove the top to fix it. I can’t get the screws here we are…10 months later…I’ll be taking my lawnmower to a repair shop.”

    • “By the third mow the mechanism that secures the handle had stripped and the handle could slide freely up and down at least a foot in height while mowing.”

    • “Plastic cutting deck is tough but not metal.”

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

Bottom Line

The Greenworks 60V 21” Lawn Mower is a lightweight, easy-to-handle machine perfect for keeping your lawn neat. It's got a lasting battery good for small to medium yards and is quiet so it won't disturb the neighborhood. Set up is a breeze and it folds up for simple storage. With low upkeep and no gas fumes, it's a solid eco-friendly choice. However, it might struggle with tougher grass and the build quality could be sturdier. Some folks have issues with the battery too.

Special Features

  • High-Performance Battery Power: Just like a muscle car, this mower has a strong motor that can spin the blades really fast—3200 RPM—so you get a clean cut every time, without the stinky gas smell or loud noise.
  • Extended Runtime: It's like having enough gas to keep mowing for a full hour, covering half a football field on a single charge of its battery.
  • Enhanced Power and Quiet Operation: It's stronger than many battery mowers and way quieter than gas ones, so you won't bother the neighbors or hurt your ears.
  • Weather-Ready Design: The mower is built tough to handle rain or bad weather, so a little water won't stop it from getting the job done.
  • Dual Battery Port with Auto Switch: It's like having a backup gas can. When one battery runs out, it switches to another without you having to do a thing (just remember, the second battery is sold on its own).
  • Versatile Cutting Options: You can do whatever you want with the grass clippings: mulch them back into the lawn, shoot them out the side, catch them in a bag, or even suck up leaves.
  • Space-Saving Storage: The handle folds down so the mower stands up on its end, taking up way less room in your garage or shed.
  • Visibility-Enhancing LED Lights: It has headlights like a car, so you can mow early in the morning or after the sun sets without missing a spot.
  • Hassle-Free Operation: Starting it up is a breeze—just push a button, no yanking a pull cord or dealing with engine maintenance.
  • Eco-Friendly Lawn Care: This mower is good for Mother Earth since it doesn't need gas or oil and doesn't spit out nasty fumes.


  • Q:

    Is the grass catcher bag included with the 16, 19 and 20" models?

  • A:

    Yes, it is included in all the g-max models that are presently on sale today. The bag Is very easy to empty and put back. The height adjustment on the mower is a piece of cake. Very pleased with the 16 inch model. If your yard is large get the 19 inch as it comes with 2 large 4.0 amp batteries for $309 today only (4-24-2014).

  • Q:

    Does it have a battery level indicator?

  • A:

    The battery has a small button on it that you push and little lights will display the amount of charge remaining

  • Q:

    How well does this mower cut? Does it provide a nice, even cut like a gas mower? Currently have a push reel mower that leaves lawn looking unfinished

  • A:

    On shorter grass or frequently-cut areas, I only have to go over it once, and it does provide a nice even cut. It's also very easy to adjust the cutting height to account for the terrain, your preference, etc. On longer, thicker grass, I've had to go over it twice, but I would also have had to do that with the gas push mower I had before. This mower is also super-light compared to my old gas mower, and is nice and quiet. Last, but not least, it mulches really well; I haven't even used the bag that comes with it.

  • Q:

    Does this mower use a cutting blade (or does it use a cord like a trimmer has)? Thanks !

  • A:

    It has 2 twin metal mower bladed about 6 inches long which can easily be replaced later if needed. The mower does an EXCELLENT job of cutting and mulching.

  • Q:

    Just got this lawn mower, fully charged the battery but the lawnmower would not start. Is the battery light supposed to stay on??

  • A:

    Hello Kaew,The battery light will not stay on. Here is the start procedure for our mowers. This information is located on page 16 of the owner's manual.
