Hello Big Green.
Thank you for your feedback. We are glad to hear you are enjoying the performance, cut quality, and quieter operation of the 80V 21" Self-Propelled Lawn Mower (LM2138S). We understand your concern about long-term battery performance, as runtime and battery lifespan are important factors for overall satisfaction. Battery longevity can vary depending on usage conditions such as grass thickness, cutting height, and terrain, but maintaining best practices, like avoiding full depletion, storing the battery in a cool, dry place, and charging it after each use, can help extend its overall life. For optimal runtime, mowing regularly and not removing more than one-third of the grass blade at a time can also reduce strain on the battery. You may also find it helpful to review official Greenworks instructional videos on the Greenworks Tools YouTube channel for battery care and mower operation tips, including this video on tips for storing your Greenworks battery (https://www.youtube.com/shorts/q-ITYPs3yBo?feature=share). If you notice any significant decline in performance over time, we recommend reaching out to Greenworks success team so they can review your battery and provide assistance if needed. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.

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
Posted by: JK75
from Houston, TX
Gender:Male
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.

Bought this open box 80V 21” self propelled combo package and was really impressed with the power and simple operation. My lawn is really thick and was a bit worry the self propelled mower would make it. It made the task simple and plenty of power. The weed whacked worked well but the line that was installed at the factory was snapping pretty quickly. I will need to look at some options for a better cutter line the power was great. Now that blower is something it cleaned the mess up very quickly.
