Rated 4 out of 5 by from Effective Mower Got this as my first Greenworks Tool as a house warming gift and I haven't had any issues with it. It's much quieter than a gas mower and the maintenance on it is virtually non-existent. More than worth its price. It does have 2 downsides. 1: like almost all battery driven mowers, the front wheels do not turn, so you have to pivot on the back wheels constantly. I have a yard with tons of turns and corners so the lack of turning wheels is actually a pain. 2: the "turbo" turns on too easily and takes too long to switch off which eats up the battery much faster. I have about a quarter acre and about 2/3 of the time I have to use an entire 4Ah and a 2Ah battery to get the job done.

Rated 4 out of 5 by from Works well Used for over 2 years and have had no issues with operation. Would have liked even better if the company had design an easier way for removing battery from mower. The door over batteries does not allow easy access and the battery is so recessed that is very difficult to remove. However, made a strap of sewing ribbon that encircled battery top to bottom on sides away from charge prongs and was able to push battery release button and pull up on ribbon to remove. Should be easy to design that into battery or include in kit.

Rated 5 out of 5 by from My Review for 20-Inch Dual Port Battery Lawn Mower I bought this mower about a month ago. Since we have had so much rain I have only been able to mow 3 times. Great Power on this mower. It cuts evenly, and power increases power when you get into higher grass. It is very quiet. The only thing that could be better is the battery is hard to take out. No finger room, My wife is going to make a strap to place under battery to make it easier to lift out. This is my second Greenworks mower. I also have a Chain saw, Trimmer, and Blower. Great High Quality products.

Rated 5 out of 5 by from With every penny. I bought this mower about two months ago to compliment my other Green works tools (40v blower, string trimmer and chainsaw) I'm so glad I got it! This thing FEELS like a "real" lawnmower. I was afraid it would feel cheap or flimsy, but this has exceeded all of my expectations. It seems to be very well built, I love the one lever height adjustment and the fold up storage feature. I live on a large property and use this mower to cut around my pool and some other areas that I can't use my riding mower for. It works great, it's super quiet and best of all it starts EVERY time. I have two 2.5ah batteries (which are about two years old) and I get about 15 minutes of cutting from each one. That's more than enough for what I need. I would definitely (and have) recommend to a friend.

Rated 5 out of 5 by from Powerful and quiet I bought this expecting a gas-equivalent mower and was pleasantly surprised with its power. We bought a house some time ago and the lawn had grown to a full 8 inches. Not only did the mower go through it with ease (4 full bags of clippings), but there was plenty battery life left. It's definitely an upgrade from gas mowers in the same price range!

Rated 4 out of 5 by from Great Mower for Regular Use I've owned this one for about a year and am overall very happy with it. I owned gas and was tired of the mess. Switched to a corded and got tired of switching outlets. The obvious next step was cordless. I did some research and found greenworks to be a good value for my money and I haven't been dissapointed. First impression is that it's built well and easy to use. My biggest complaint is battery life. If you have a decent size yard you'll need more than one battery. Also if the grass gets too long or it's too wet it'll eat up the battery very quickly. It can handle most of what you throw at it but I strongly recommend buying another battery or even two. Otherwise I would definitely recommend it to anyone looking for something lighter in weight, quieter, and easier to use than the gas competitors.

Rated 1 out of 5 by from Don’t waste your money I bought this 2 weeks ago my yard takes around 30 minutes to mow. The first time I used it I had to charge it twice the second time mowing the battery will only last for 1-2 minutes. I called customer service to get a new one they said I need to email back in 2-3 weeks so they can ship me one. Don’t really know what I am suppose to do til then they will not cover the cost of me buying a new battery so I can have one to mow with until they can get me a new one in a month. Dont waste your money im out $380 and going to have to go but another mower.

I really like this so far! However, there is a concerning high pitched beep/whine that consistently goes whenever I start the blades. I'm not sure what that is coming from. the batteries are in position correctly as is the Mulch plug. Is this normal?

with my 40V dual port 20" mower the blade speed increases once in a while for less than a minute. I know it is suppose to increase speed when more power is needed. Any way to increase the speed all the time? It cuts better then.

Asked by: JerryLJ
Hello there, No unfortunately there is no way to prevent the speed of the lawn mower from lowering again after it revs up.
