Expensive replacement battery
on July 17, 2026
Posted by: Tom's review
The trimmer works well but it is a little heavy due to the battries weight. Expensive to replace trimmer feed line and battery is very expensive, I hope it lasts a long time before it dies.

Thank you for sharing your feedback. We are glad to hear the trimmer is performing well for you, though we understand your concerns regarding the weight and cost of replacement items. Battery-powered tools can feel heavier due to the battery, but they are designed to deliver consistent, high-performance power without the maintenance of gas equipment. One of the key benefits of the 80V platform is that the battery is interchangeable across a wide range of Greenworks 80V tools, allowing you to expand your lineup without needing separate batteries for each product. To help maximize battery life, we recommend storing it in a cool, dry place, avoiding extreme temperatures, and fully charging it after each use. For the trimmer line, using the recommended size and minimizing contact with hard surfaces can help extend its lifespan. We appreciate you taking the time to share your experience and hope your equipment continues to perform reliably for you over the long term. If you ever have specific questions or concerns about our products, contact Greenworks via chat on our website, call us at 1-888-909-6757 (1-888-90WORKS) or refer to the FAQ ask section of the tool or ask us a question, anytime.

80V package not very impressive
on July 11, 2026
Posted by: drassuorb24
from NW Louisiana
Gender:Male
Purchased: March 12, 2026 - 80v mower, trimmer, blower combo
Notes: First purchase of battery powered mower. Yard is small (6,000 sqft). St. Augustine grass.
Pros: Sturdy construction, made in USA, blower is awesome
Cons: Battery runs out after 30 minutes. Purchased 80v for longer run time.
Trimmer is heavy and cumbersome. I'm still using my old Ryobi trimmer because it is so light and easy to use. Was going to buy a Greenworks edger attachment and extra 80v battery, but Ryobi edger with battery and charger was less than half the cost of Greenworks.
Mower motor response is slow to rev up for thicker grass, leaving uncut blades of grass all over the yard. Wheels lock up if you pull backward after releasing self propel.
My takeaway is that I don't feel like there was any advantage to buying the 80V package.

Thank you for sharing such detailed feedback. We are glad you found the construction solid and are enjoying the blower, but we understand your concerns about runtime, tool weight, and overall performance.
Battery runtime can vary based on grass type and cutting conditions. Thicker grass like St. Augustine may require more power, which can reduce runtime and affect cutting consistency. Raising the cutting height slightly and mowing more often may help improve performance and reduce strain on the motor.
For Greenworks rear-wheel self-propelled units, the drive system is designed to assist forward mowing and improve traction. When backing up, release the self-propel lever before pulling the mower rearward. If the wheels feel locked, stop, allow the drive system to fully disengage, and then pull back slowly with the handle slightly lifted. If the issue continues, please refer to the owner’s manual for model-specific guidance.
We also appreciate your feedback on the trimmer weight and mower response. These comments are valuable and will be shared with our team.
If you would like us to help with optimizing the tool’s performance or exploring options, our Success team is available through the Greenworks Tools website Contact Us page, either through Chat or by phone at 1-888-909-6757. Thank you again for trying the 80V platform and for sharing your experience.

Really disappointed in this replacement. Why can't they provide one just like the original?
First to get more string you have to hit the green button against the ground and green stuff shows up on the sidewalk. Secondly, and this is might be my fault, but replacing the string isn't as intuitive. The unfortunate thing is everywhere I look, all the replacements are just like this one.

Thank you for your feedback. We are sorry to hear the replacement string head did not meet your expectations. The design may differ from the original, which can affect both line advancement and the restringing process. If you are having trouble with line feed, try making sure the spool is installed correctly, the line is wound evenly and not overfilled, and the trimmer is being used with the proper line length. If the line does not advance smoothly, lightly tapping the bump knob on a clean, hard surface may help. For restringing, checking the diagram in the manual and confirming the line is routed in the correct direction can also make the process easier. Your comments regarding usability and performance are valuable and will be shared with our team as we continue to evaluate product design and improvements. For additional guidance or troubleshooting, our success team is available through the Greenworks Tools website Contact Us page either on Chat or by phone at 1-888-909-6757 and may be able to assist further.

I've had this trimmer for a few months now, and i'm very impressed by how much power it has as well as great runtime. It has lasted well over an hour a few times now with power to spare. Charge time is about an hour, sometimes less. Cutting is very strong, and i've never had to use the higher output setting on it. I do recommend getting the shoulder strap like I did. The unit is a bit heavy. I would compare the electric to a gas powered trimmer as far as weight goes. Pretty similar. Definitely a great residential trimmer. I won't recommend this to a commercial user. You would have to by several batteries to be on standby for all day use.

The compatibility of the product is overstated. I had to file the string openings for proper fit. However, I would purchase the same product again.
I would recommend this to a friend!

Hello Char23.
Thank you for your feedback. We are glad to hear you would purchase the spool cover again, but we understand your concern regarding the fit. Compatibility can vary slightly depending on the specific trimmer model and wear on existing components, and we appreciate you pointing out the need for adjustment in your case. However, adjusting the string openings for proper fit is not recommended, as modifying the part can affect its integrity, interfere with proper string feed, and potentially impact safe operation. Your feedback on the string opening fit is helpful and will be shared with our product team as we continue to improve fitment and compatibility across models. If you need help confirming compatibility or would like assistance finding the correct part for your trimmer, please contact our success team with your model and serial number. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757. We appreciate you taking the time to share your experience.
