What buyers say about Greenworks 20-Inch 3-in-1 12 Amp Electric Corded Lawn Mower
I was mowing the yard in 3 minutes, it looked better than before, it was light compared to gas, and it was powerful, it Starts very quickly, and never buy fuel or run out half.
I bought this mower as a spare, but now I intend to use it more than I thought, first in the spring when the grass is starting to grow, then in the summer when it gets heavy, then switch back to the electric.
After 13 years of use, I decided to go with the GreenWorks 25022 12 Amp 20-in 3-in-1 Electric lawn mower, because I had seen the death of my old one and had some apprehension about what I would find on the market today.
The downside of corded electric lawnmowers is that they can't be used on trees or shrubs, which is a problem if you have large lawn, and I don't have a can of gas or a lawnmower in my garage.
I have had it for about two months now and it works well, cuts well and is very easy to store in the back of my car.
Common Questions
Correct, the Coleman outdoor extension cable is not enough Amps for this mower.
If you need 100 feet, some would recommend a 12 gauge cord, while others would only recommend a 14 gauge one.
How long is it and what is covered if there is a warranty?
The bottom motor bearing just blew out on mine 2 months after the 4 year warranty expired so I guess I'm boned.
Is this mower self-propelled?
It's very light and you just need to empty the bag when it feels heavy.
What is the length of the cord?
It does not come with a cord, you need to purchase a separate outdoor extension cord for your use.
When it can mulch, what are the benefits of using the side discharge?
Most people use the rear bag, it's good for keeping grass low, but the higher the grass, the harder it is to cut.
