Rated 3 out of 5 by from Gets the job done, but some issues Got this as a Christmas gift two years ago. The mower works well enough. Sometimes you have to mow a spot twice if you let your grass get too long. Keep up with your mowing on at least a biweekly interval or else your battery won’t make it. Battery life could be better. My biggest issue is with the charger. It shows fully charged batteries when my battery is obviously empty. It won’t charge all the time, and sometimes all it does is heat up my battery. I went with battery operated mowers because I was having an issue fixing my gas mower, and I can store this mower vertically. I would recommend getting a mower with a better battery life or more reliable charger.

Rated 1 out of 5 by from Bad battery run time Battery life sucks a*s less than 10 minute run time on a full charge. and that is being nice. the grass was 2 inches tall cut down to 1 3/8 inch. So the grass was NOT the problem

Rated 5 out of 5 by from Quiet and Effective Assembled in a few minutes. Used it for the first time today. Such a good experience. Cut through heavy Florida grass without any issues. No fumes, quiet, and very effective. Have been pleased with the other Greenworks products, so I had high expectations for this, as well.

Rated 5 out of 5 by from Perfect for me! I absolutely love my Greenworks battery operated lawn mower! I am in my 60’s and our old gas mower was just too heavy and bulky for me to use. I can get the job done in no time now and store it on the wall since there’s no fluids in it!

We Have charge both batteries but lawnmower will not turn over we’re wondering if maybe the starter switch is wet or damaged? Also a red light comes on on the right side even though we know if charge both batteries fully.

Asked by: Marcela33
Hello Marcela33, We're sorry for the troubles you're experiencing. Please ensure that you're starting the unit in the correct order. If this is done in any other way you will not be able to start the unit. 1. Push and hold down the safety button. 2. While the safety button is being held down lift up the bail lever. 3. Once the unit starts you can now release the start switch and continue to hold onto the bail lever. This is the only way in which the unit will turn on. If done in any other order the unit will not turn on. The light from the battery compartment simply advises which side is being used.

How long do the batteries last? The charger says both are fully charged, but the mower won’t start. Bought this about 3 years ago. 

Asked by: Lorna
Hello Lorna, If the charger has been left plugged into the outlet try resetting it by unplugging it and plugging it back in. You may have to do this twice to ensure a complete reset. If the battery is too warm it will also not charge. Secondly, ensure that you are starting the unit in the correct order. Hold the safety button down, while the button is being held down, lift up the bail lever (start lever). Once the unit turns on release the safety button and continue to hold onto the bail handle for the duration use. Each time the unit turns off you must start it in the same sequence. Any other way and the unit will not turn on. We hope this information has helped.

What is the cutting range of this mower? Thanks.

Asked by: 407l
Hello 407I, Thank you for your question. We recommend cutting your grass with the 2.5 Ah to determine the estimate run time you will achieve with this battery, keep in mind the run time will be depending on the type, length and thickness of your grass. Our 20-Inch Lawn Mower, 1302602 is part of our 40V GMAX line of tool, if you have other GMAX batteries, they would be compatible with the lawnmower for an uninterrupted cutting experience. The only additional information we would like to provide you with, is that when it comes to the run time of the battery, the higher the amperage it has, the longer the run time you will achieve. Please let us know if you have any additional questions or comments regarding your unit. You can contact us by calling our customer support center at 1-888-909-6757 or by e-mail at info@greenworkstools.com.
