The Greenworks 25022, 12 Amp, 20 Inch 3-in-1 Electric Lawn mower is the number one bestselling electric lawn mower on Amazon and for a good number of reasons too. Reliable and simple, this mower packs in a sufficiently large 12 Amp motor that drives an equally massive 20 inch steel deck through any and all kinds of grass growth with ease. Add to this a total of 7 height positions and you can trim down anywhere from 3.75 inch to 1.5 inch. Everything about this walk behind mower is inspired by proper ergonomics. Adjusting the height is possible with a single lever that simultaneously lowers all four wheels. The handle folds up to help store the mower. Be it maneuverability, reliability or even cost of maintenance, this Greenworks electric lawn mower tops the chart!

In-Depth Review of the Greenworks 25022

Ease of Use

From the onset, you will find that this is a pretty easy mower to use. Before I get into all the praises for the Greenworks 25022, 12 Amp, 20 Inch, 3-In-1 Electric Lawn Mower, keep in mind that this is a corded electric mower so the cord is not going to get out of the way all by itself. Best way to get around this complication is to start from the closest portion to the plug point and move in a pattern such that the cord automatically unravels over mowed surface rather than coming in front of the mower.

As for mulching, there is a plug that goes into a slot inside the spring-loaded back door. That’s about it to start mulching. To side discharge or bag, remove this plug and attach the necessary accessory. Mind you, because of its superior quality, the side discharge bag and rear bag are expensive but they are incredibly good. Adjusting height is also a breeze with a single lever that locks in 7 different positions. And finally, the front 20 inch deck being made of steel is rather thin so you can get incredibly close to edges, pipes or any obstruction in your path.

Also Greenworks made some super handy instruction videos on how to use the cord retainer, install the mulching plug, etc. Take a look here.

Cut Quality

12 Amp motor with a large cutting deck, plenty of power and superior construction all translate to an amazing cut quality. Because you end up with lesser number of passes, more torque on the blades, grass or all variation get the same treatment, in other words you always end up with a level lawn.

Height Adjustment

Total of 7 heights to choose from ranging between 3.75 to 1.5 inches all adjusted with a single lever. Even at 1.5 inches you won’t be scraping the ground thanks to the thinner deck construction so when necessary give your lawn a tight crop without worrying about damaging the top soil.

Motor Power

12 Amp motor that garners a lot of positive review anywhere you read, that’s one major reason why I rate it so highly. Usually good mowers lack an equally powerful motor with the ability to handle more than just grass. Not this Greenworks push mower, it packs sufficient power and being electric is super silent.


Forget maintenance forever with the Greenworks 25022 electric lawn mower. Keep it in a shed, leave it out exposed to the environment or chain it to the ground through a tornado, this technological marvel will purr to life the moment you switch it on.

Cost Effectiveness

If you are on a tight budget but don’t want to skimp out with a cheap mower that will probably breakdown in its first tryst with an exposed root then this Greenworks mower is what you need. I am not saying that this is an affordable mower, there are a few cheaper than this model, but there are definitely many more much more expensive and not as good as the 25022. The mower is backed by a 4-years warranty.

  • Well built, sturdy design
  • Excellent overall performance
  • Powerful 12 Amp motor
  • Rear bagging, side discharge and mulching capabilities
  • 7 Height positions



  • Single lever to change heights
