Great mower so far!

[This review was collected as part of a promotion.] My favorite song I bought this motor to replace a underpowered Hart brand mower than I had. Mower performed really well even in thick grass and turbo feature helped to make sure it stayed ramped up between grass thickness levels. The light is a nice touch for dusk mowing so you can mow in the cooler evening and avoid the wet dewy grass of the morning if your trying to avoid the Florida heat like me. Height adjustments were easy to switch Ns very lightweight so no self propelled didn't bother me at all. Only Con I had was more because of the morning dew making the grass wet so it clumped at the side discharge instead of freely flowing out.
I would recommend this to a friend!

Fantastic unit

[This review was collected as part of a promotion.] 3 rd year going strong. This thing is a unit it's chewed through tall grass and weeds and gargled chunks of storm debris and it just doesn't care. I haven't even sharpened the blade once. I just got it out to mow sections where repairs from the storm could have left more debris and I don't want to damage my 25 inch newer model.
It chewed through 6-7 inch grass in mulch mode on height setting 3 and wouldn't quit and the grass looked even
despite it all.
I really just wanted the twin battery 21 inch but could only find the 25 inch twin blade. I really wanted self propelled and manual turbo control along with 2 battery ports for the extra energy used. I like the 25 inch it does pretty good so far, but that 21 inch model is strong and hard to beat. Also feels light as a feather.

Side discharge is the only weakness at that is highly dependant on when you mow and what settings. Unlikely to throw rocks and have to sweep grass though.
Pros: Convenient, Easy to Use, Quiet, Durable, Effective, Powerful

Looking good

Purchased in April 2026 and so far has been excellent doing the areas around my house. I am a 74 yo female and own a bit under 3 acres so this is augmenting my rider mower.
Definitely was easy to put together once delivered and have found it easy to handle even on the slight slopes and around my trees.
Battery life is decent .. though will probable purchase a second since i do need to recharge .... which is done in less than 45 min. to finish up.
Stores easily once folded ..... I don't uses the bag so use the side discharge for mulching ....I am consistent in cleaning the under carriage after each use ....
Will see the durability and longevity

Verified Purchase:Yes
We live in the mountains with a hillside in our backyard. Our first mower did a fine job on flat terrain, but I had to push it up the hill. We searched for a high quality, self-propelled mower and decided on Greenworks 80-volt. It has all the features we were looking for. Now it mows the hillside with ease, as I am able to hold the controls with one hand and walk comfortably along behind. It is now a "piece of cake" to mow! No sweat, literally.

Not enough power to finish .35 acres.
on May 27, 2022
Posted by: RTP mark

I have had this mower for a month and a half so far and used it to mow my .35 acre lot 4 times so far. With both batteries fully charged, I have never been able to completely finish mowing my yard. The batteries are drained before I can finish. I need the batteries to last 4-5 more mins but they are drained before I can finish. I attempted to recharge the first battery to be drained while using the second battery. The drained battery sat on the charger for 15 mins but the red light on the charger apparently stayed on the entire time so it never gets charged. That may be a protective mechanism for the batteries but it means I will need a third battery in order to mow my lawn without taking a significantly long break from mowing. I also have tried rationing the use of self propelled but I still can finish mowing my lawn with the two 2.5ah batteries. Very glad I have not surrendered my gas powered mower yet.
No, I would not recommend this to a friend.

Hello M_D_In_NC,
Thank you for your review. We are sorry to hear about the experience you have encountered with this product. Here are a few troubleshooting suggestions to check out.
1) When the battery is inserted, the light should begin flashing green to indicate the battery is charging. If this light is not igniting or is flashing red, this may indicate an issue and we would be interested in hearing more about this. If the light simply goes solid red, try removing the battery and unplugging the charger for about 10 minutes and place them both indoors in a room temperature setting, as this might indicate the battery is at the incorrect temperature to be charged.
2) Ensure that the battery has been fully inserted into the charger. Sometimes this requires a firm push into place to make sure that it has been properly seated.
3) Try resetting the charger. To do this, simply unplug it for approximately 10 minutes and then plug it back in and try reinserting the battery. If the charger has been plugged in for extended periods of time, this can sometimes cause the charger to malfunction.
Should you continue to experience a problem with the battery and charger, please contact us at 1-888-909-6757 (1-888-90WORKS). All we ask that you have access to the battery and charge so that we can complete troubleshooting with you and gather necessary unit information

Broke within 6 months

My father purchased this for me when I purchased my first home, and it was working great, until, during my last mow of the season, it would not turn on anymore. I did the troubleshooting so I assume it is an issue with the start handle, but I have been unable to reach their customer service team.
Pros: Quiet
