Rough lot needs different tools first.
on June 17, 2026
Posted by: Rough ground
from Detroit, Michigan
Gender:Female
I bought this item to mow two vacant lots on my block. The ground was so rough with weeds that I only cut the berm and 3 feet of the front lawn while burning through half of the battery. The mower struggled to move forward. There were some rough weeds on the site which did cotribute to the difficulty. So, I'll go back with a swing blade soon. I became exhausted. I'll try again soon.
Pros: Environmentally Safe
I would recommend this to a friend!

Thank you for your feedback on the 80V 21" Self-Propelled Mower (SKU 2550402 / MO80L416). Based on your description, it sounds like the conditions, heavy overgrowth, uneven terrain, and thick weeds, were beyond what a single-pass cut is typically designed to handle, which can lead to higher battery draw and reduced self-propel performance. For best results in these environments, we recommend first clearing the area to reduce overall vegetation height, then mowing in stages rather than attempting a full cut in one pass, starting at a higher deck setting and gradually lowering it on subsequent passes to avoid overloading the blade and drive system. Slowing your forward pace and ensuring the underside of the deck is clear of built-up debris can also help improve airflow and cutting efficiency, especially in dense growth. In very rough or uneven lots, breaking the area into smaller sections and avoiding wet or matted weeds will further reduce strain on the battery. For additional guidance, Greenworks Tools also offers an official instructional video on mowing overgrown grass conditions, which demonstrates best practices for tackling challenging terrain and maximizing runtime. We hope you will find this information helpful. If you require any additional support or have questions regarding a product, we recommend trying our Q&A section on products' page or Chat with us direct on our website or call 1-888-909-6757. We are here to help.

Nice Mower - Worth the Expense
on June 6, 2026

Easy transition from my garden tractor to this self-propelled mower. Can do my full yard using only 2/3 of battery. Mulches very well without binding up as long as the height setting is correct - no clumps of grass left. Turbo boost for dense grass kicks in nicely and gets you through quickly. Self-propelled feature is great as the mower is a bit heavy. So far so good after two mowings. Get great exercise and the lawn looks nice. I have to do much less trimming with my Greenworks weed-wacker as I can get closer to the edges with the mower than I could with my tractor. A bit expensive but I am completely satisfied with the performance and the look of my lawn.
Pros: Quiet, Durable, Environmentally Safe, Effective, Powerful

Cant use self propelled and mower at same time
on June 4, 2026
Posted by: Tim the tool man
from Texas
Gender:Male
Bought this lawnmower in April 2025, in July 2025, it would die while running, if I let self propelled switch off lawnmower would start right up, then 10-30 seconds later same thing, batteries showed about 1/2 power. Charged batteries and mowed over a newly cut lawn so no strain and ot did the same thing. Contacted Greenworks and the sent out a new replacement, but the same thing happened, again I Contacted Greenworks and they sent out another new one, tried it out today, and it started doing the same thing. There has to be a manufacturing defect in this lawnmower with both self propelled and blade are engaged. It does NOT cut out ever if I use as a push mower, but kind of defeats self propelled feature.
Pros: Quiet
No, I would not recommend this to a friend.

Hi Tim the tool man. Thank you for your feedback. We are sorry to hear this was your experience. If you are able to cross-test the batteries with another charger and another unit, this can help determine if the battery may be the issue. Should you have any further questions or warranty needs, please contact us directly through chatbot on Greenworks Tools website that will direct you to a live agent or call us at 1-888-909-6757 (1-888-90WORKS). Check out some helpful tips to extend your run time!
1) When cutting thick grass, reduce walking speed to allow for a more effective cut and a proper discharge of the clippings.
2) Only mow 1/3 of the total grass length at a time - no more. For a healthy lawn, always cut off one-third or less of the total length of the grass. The average lawn should be approximately 1 1/2 to 2” (3.8 to 5 cm) long during cool months, and between 2" to 3 1/4" (5 cm to 8.3 cm) long during hot months.
3) Mow when the grass is dry. As this is an electric unit, mowing wet/damp grass is a safety issue. However, ensuring the grass is dry will also help the grass cut cleanly and discharge appropriately. Wet/damp grass carries more weight and will mostly stick to the blade/motor shaft and will not appropriately discharge or cut easily.
4) Make sure the battery is cool before use. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging.

I do like the light weight, and quite functioning. However, I have tried multiple times/setting to get it to mulch and not leave a mess behind (clumps of non-mulched and missed blades of grass) on my healthy yard, even when barely taking anything off the top. I have reached out to Support and they sent me the "best" blade they have (which looked just like the one it came with), this was of no benefit. I pulled out my ~20+yr old gas mower and it still does a much better job of cutting and mulching than this mower (leaves little to no visible remnants). Maybe it would work better on a yard not as healthy and thick as my small yard.
I would recommend looking elsewhere for a battery powered mower.

Hello RGCvik.
We are sorry to hear the mulching performance has not met your expectations, especially since you have already taken the time to try different settings and even worked with support on a blade replacement. While it is good to hear you are enjoying the lighter weight and quiet operation, clumping and visible clippings can occur when grass conditions are too heavy, damp, or when too much is cut in a single pass, even on healthy lawns. For best mulching results, we recommend mowing more frequently and ensuring no more than one-third of the grass height is removed per cut, as well as confirming the mower is set to the correct mulching configuration with a clean, properly installed blade. Cutting at a slightly higher deck setting and reducing ground speed can also help improve airflow and clipping circulation under the deck. That said, we understand your comparison to a gas mower and appreciate your candid feedback. If you would like additional support or a technical review of your unit’s performance, the Greenworks Tools customer success team is available to help further. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.

Self-Propelled Drive Motor Issues
on May 13, 2026
Posted by: KD985
I bought this mower about two years ago. Since then, the power module and main motor have been replaced (outside of the warranty - it simply became too difficult and time consuming to process the claim). Today, the self-propelled drive motor failed leaving me to push the mower now. Greenworks does not provide a comprehensive parts diagram and list for this mower so you have to call the call center for more information. Replacement parts are limited or unavailable for this mower.

Hello KD985.
We are sorry to hear about your experience and understand how frustrating it can be when the self-propelled function is no longer operating as expected. Based on what you described, there are a few areas that may be helpful to check. Ensuring the drive control cable is properly connected and has not become loose or stretched over time can help, as this directly affects engagement of the self-propel system. It may also be worth inspecting the rear wheels and drive gears for any debris buildup or obstruction, as well as confirming that the height adjustment is even on both sides, since uneven settings can impact traction and drive performance. Additionally, checking that the battery is fully charged and properly seated can help rule out power-related inconsistencies.
We understand your concerns regarding parts availability and documentation, and your feedback is important as it helps identify opportunities for improvement. If the issue is not resolved after these checks, we recommend contacting our support team directly so they can further assist with troubleshooting and review available service options with you. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.
