I have only used my new mower one time but WOW! i am a 69 year old woman and was looking for a light mower. i was initially upset it wasn't 21 pounds (almost returned it) but it is still feels pretty light and handles easily. it cuts like a charm with one pass. i was able to do my lawn in about 15 minutes! (previously would take me 40 minutes with old mower repeating areas to get all the grass cut) so the power level was very satisfactory and the blades did the job the first time. i was giddy at how great it mowed! not wanting to stop i then did the side yard (about as big as the front yard, and then a little out front by our field and still had 2 dots left on my battery. i used it totally about 35 minutes and didn't even break a sweat. our lawn is on a hill side and only needed the self propel when i was going uphill. i only had it on the second lowest self propel level and it took me uphill like a charm. and as someone else said... be sure to let go of the self propel handle when making a turn on the back wheels or it will take you for a ride!! i did not need the self propel to go sideways or downhill. without the self propel on you can mow backwards also and just lift the front and and place it down into small areas and it cuts great that way also. and i did not have to repeat areas to get the cut nice like my previous mower which admittedly was a battery powered self propelled reel mower . best yet - the grass looks fantastic.

I got this on sale and I'm glad I did. It wasn't difficult to put together and it's very easy to use (push button start while holding a bar down). The self-propelling feature works well. I have a hilly property where almost nothing is flat, and I find I need 2 8 hour batteries to do about a 25 feet x 80 feet area. I only use the self-propel bar on the uphill. It works amazingly until it hits grass that's 3 feet tall, then it tends to choke up. It's at the upper limit of what I can lift into my pickup without a ramp. I wouldn't want to lift it often.

Had for about 4 years. Cuts great and never needed to change blade in that time. I only bought this because I already had 4 other batteries and like 3 chargers. Do not bother if you only have 1 4 ahr battery, you will need at least 2-3 for a quarter acre lot. Battery time is inversely proportional to grass length, I will use 2x the batteries mowing every other week rather than every week. If you have nice thick grass you can multiply the number of batteries you will need by another 2x. Like I said, cut is great, but you really want like 4 batteries for a decent size yard (1/4 acre, with thick grass), unless you are mowing literally every week.

The mower does a great job but you will need extra batteries
Reviewed in the United States on June 17, 2025 by joe mcgee
I bought a Greenworks electric lawnmower in the winter when it was marked down so I didn't get to use it until the spring. I used it twice and then had an unrelated accident. I couldn't mow myself so I hired someone and my new mower sat in the garage. I kept the battery indoors except when I needed to use my Greenworks chainsaw. The battery remains in good condition. Now the lawnmower won't start. I know the battery is fully charged. Nothing has happened to the lawnmower, it just sat in the garage. I saw videos online that said to take it apart an look for a loose wire. I'm not going to do that. If I take it apart, inevitably something won't go back right and I'm left with an even bigger mess. I called some local lawnmower repair places and they said they will not work on Greenworks. I went online to try to find a Greenworks repair facility and I got a run around from every crook that knows people will be looking for a repair for this brand. I didn't buy the extended warranty so I'm not expecting to get anything back from them. I just want to warn anyone thinking of buying this product. If you do buy it, get the warranty because it most likely will fail on you.

This is a great product. It cuts my Saint Augustine grass very well. One thing I would recommend is that you buy a second battery my lawn isn’t that big and I use about half of my second battery, particularly when the grass is long. I have had self-propelled lawnmowers before. Some of them have a speed that is way too fast for me. This one has a great walking speed and even if it’s too fast for some people it easily controllable through the power handle, which is right at your fingertips

It's OK. I would have gone with a different brand but this was within my budget.

This mower is awesome. You will not regret this purchase. Although the width is small, it still gets the job done.
