GreenWorks 25022 20″ 12 Amp Corded Electric Lawn Mower Review

The Greenworks Tools 25022 is a top-selling electric mower that is dependable, easy to use, and durable (at least so far after a few mowings I had the pleasure of using it on). It contains a 12-amp engine that easily powers an impressive 20-inch steel deck. The 56-pound Greenworks 25022 is easy to push and has a highly functionable, ergonomic design that makes it a breeze to maneuver despite the cord that I’m still getting used to. I always disliked the cord tethering me the outlet. When the grass is really long, it can often get kinked up in the tall grass and sometimes I fear I may run over it.

The wide 7-inch front wheels and 10-inch back wheels roll easily over lush green grass or hard, clay-like surfaces that contain things like acorns, sticks, and pebbles. And the “3-in1” feature of the mower allows grass to be stored in the rear bag, emitted through the side discharge space, or mulched. The mower is designed for yards that are small- to medium-sized, and its dimensions are 26.9 x 18 inches. This is ideal for the average homeowners lawn.

Key Features

  • 12 AMP motor provides exceptional power
  • 20″ steel deck is extremely durable
  • 7 height positions for grass between 1 1/2″ – 3 3/4
  • 3-in-1 grass clipping options – rear bagging, side discharge & mulching
  • Wide 10″ rear wheels + 7″ front wheels for a variety of terrain
  • No gas, pull cords – maintenance free
  • Compact storage options


This is a sturdy mower that has a large cutting deck and lots of oomph in terms of power. The mower cuts grass like a champ, though it’s recommended to have the blade sharpened before you first use it if you want to make sure that your first mow is perfect right out of the gate. I’m not complaining that their blades are dull, it’s just my personal preference.I found that the GreenWorks 25022 cuts grass evenly throughout the entire yard and is highly maneuverable because the deck is rather thin. This feature comes in handy since you can get close up to “obstacles” in the yard such as trees, flower beds, mailboxes, and light posts and mow easily around them. Also, it’s not what I’d consider a heavy, hard-to-push mower, so mowing on slight inclines isn’t a big deal. This is one of my first electric mowers from GreenWorks i’ve had the pleasure of reviewing (though I’ve seen other ones used), and I was amazed at the quietness of it.

Ease of Use

The GreenWorks 25022 is compact and starts right up like a dream. You plug it in, turn the included safety key, and then push the starter button. I’ve had past gas-powered lawn mowers that make you feel like you’re tearing your shoulder in two when trying to start it, but this mower isn’t like that at all.

The mower does not come with an extension cord, so if you don’t have one handy, get a really good one. I suggest purchasing a 16-gauge extension cord if your yard is less than 40 feet. Otherwise, a 14-gauge cord should do the trick. The more you mow with the GreenWorks 25022, the more adept you’ll become at avoiding the cord. Using a cord in general for a mower is not an ideal setup, but then again, I knew I’d have to deal with that when I bought this mower. Plus just the fact that it uses an extension cord can be annoying since you’re constantly on the lookout for adjusting the cord.

Though the GreenWorks 25022 mower is not self-propelled, it’s easy to push because it’s not heavy. Be sure to check out some of the available videos from GreenWorks that demonstrate how to operate the cord retainer and install the mulching plug. If I had one gripe, it’s that the mower is not self-propelled.

Special Features

One thing I haven’t mentioned yet about the GreenWorks 25022 electric mower is that you don’t need to mess with smelly gas and, though it does require electricity to run, you’re putting out a little less pollution in the world by using it. Even in the short time I’ve had this mower, I’ve noticed that the gasoline smell in our shed (due to our last gas-powered lawn mower that was in there) has faded away and hasn’t returned. So not to get on a soapbox or anything, but I do feel like I’m doing the environment some good by using the GreenWorks 25022. Other top features include good grass-cutting quality, ease of wheel-height adjustment, a strong engine, easy maintenance (so far), and a good price.

The wheels on my old gas-powered mower had to be individually adjusted and were a serious hassle to heighten and lower–that’s not the case at all with the GreenWorks 25022, which has just one lever that adjusts all four wheels. Though some may prefer to not have one lever that controls the height of all four wheels, I find it to be an outstanding feature.

The GreenWorks 25022 can store grass clippings in the rear bag, emit the clippings from a side discharge area, or mowers can mulch their lawn, an option in which the cutting deck will slice the grass into small pieces that will work to break down the soil of your yard at a faster rate. I recommend mulching–at least occasionally– for the overall health of your lawn.

Cut Quality & Options

Whether mowing through thick, long grass or sparse grass atop rough, clay-like soil, the GreenWorks 25022 cuts grass cleanly and moves smoothly. The powerful 12-amp motor slices through even the toughest grass, and with a total of seven adjustable height positions, mowers can trim their grass at anywhere from 3.75 inches to a mere 1.5 inches. This 3-in-1 mower has a bag to catch clippings, or mowers can simply let grass fly out of the side discharge area. Best of all, at least in my opinion, is the mulching capabilities of the mower, which have come in handy in our front yard with all the leaves that have been steadily falling this fall season. Mowers will be able to cut their lawn within an approximately 100-foot radius of the electrical outlet, which easily covers all the ground of most outdoor lawns.


This mower has handles that fold, allowing it to be easily stored, even in a car trunk if needed. The overall maintenance of this mower is low compared to the maintenance of a gas-powered mower. We store this mower in our shed, but it can be kept outside or in the garage, and it hums to life right away with the touch of a button. Greenworks offers a four-year parts and labor warranty on the mower.

Another nice thing about an electric mower is not having to worry about replacing spark plugs, and air filters, and you don’t have to replenish the gas and oil on a continual basis.

Safety Features

This mower does come with a safety key that is needed to start it up, thus making it hard for children to use it unless they had access to the key. It does not release harmful emission into the air, thus making the air quality around you much better as you’re mowing. I used to breathe in a lot of smoke-filled air using my old gas-powered mower. This is a pleasure to use and breathe in the nice fresh lawn cut air, without the disgusting fumes.

Cost Effectiveness

All told, there are cheaper electric mowers on the market than this one. But if you’re looking for an electric mower that doesn’t break down when you hit the slightest bump, then you’ll want to spend a little more money. You get what you pay for, and shelling out more money for a mower like this one, which actually isn’t even all that much money, is highly worth it.
