Fire the engineers! Battery system is terrible
on June 11, 2023
Posted by: No more greenworks
from AZ and NM
Gender:Female
I am a huge Greenworks customer and now so disappointed. There is no method to get the battery out of its cage. Your fingers cannot fit in between the plastic holder. The battery should and does not have a handle to pull it out. So after 1 year you fight with it and need an entire tool set to get out the battery. Notice the pictures don't even show you inside the cage? That's because the camera can't see inside because a stupid engineer had the battery cover fall on you. Does not stay open or go all the way up. You need a tool just to keep it open while getting other tools to get out the battery. Fire the engineer
No, I would not recommend this to a friend.

Dear No more greenworks,
Thank you for taking the time to voice your option! Our batteries do take a firm grip to pull the battery out. This is to ensure dislodgement does not occur during operation. Make sure that the tracks that the tracks on the battery are free of debris and dirt before you insert the battery, any debris can affect the movement of the battery. When removing the battery, apply a firm grip to the battery latch and place one hand on product and remove the battery pack with a firm pull.

Verified Purchase:Yes
[This review was collected as part of a promotion.] This mower is my 8th (mower, chainsaw, 2 blowers, 2 string trimmers, snow blower, snow shovel) Greenworks 40V tool that I have purchased. ALL HAVE MET AND EXCEEDED MY EXPECTATIONS. Don’t let anyone tell you the 40V does not have enough power. Granted to cut a tree over 14 inches in diameter is a little tough with my 16 inch saw. But how often do most of use have that task. The ease of operation and low noise level are so much better than gas powered. I WILL ALWAYS RECOMMEND GREENWORKS!!!
I would recommend this to a friend!

Bail switch cuts off too easily
on August 5, 2024
Posted by: DRP69
from Crossville, TN
Gender:Male
[This review was collected as part of a promotion.] I assembled my new mower and charged the batteries. I have been able to mow both front and back lawns. It takes one and a half batteries to mow each lawn. The mower starts easily and runs well.
My only complaints are that it is difficult to maintain a medium speed of propulsion. Also, the bail switch is too sensitive. I can maintain pressure with both hands, but it still cuts off too easily. Is there any way to adjust this switch?

Pros: Easy to Use, Quiet, Effective, Powerful

Poor moveability
on August 29, 2024
Posted by: DirkD
Gender:Male
When you need to pull the mower back 95% of the time the drive wheels are locked and you have to drag the wheels across the lawn. Don't know why they rarely release. Makes for a very poor and strenuous lawn cutting experience. I have several Greenworks 40V tools - weed trimmer, hedge trimmer, leaf blower and power washer. Been a good customer but now I am so frustrated with this lawn mower, i will start replacing them another brand.
Pros: Quiet
No, I would not recommend this to a friend.

Hello DirkD.
Thank you for taking the time to share your experience and leaving us your feedback. We are sorry you are not happy with the self-propelled drive system. With self-propelled lawn mowers, there are two categories to consider: front-wheel drive and rear-wheel drive. All Greenworks self-propelled mowers have a rear-wheel drive system. The self-propelled feature is not usable in reverse. They are designed to lock when pulled back to prevent damage to the drive belt. If you are using the self-propelled feature, the mower will attempt to move forward and will be difficult to move backwards. To revers the mower, you would have to release the self-propelled lever, move the mower forward at least 6 inches, the clutch in the wheels will release and you can pull the mower backwards.
Please review our video link below, Operating Your Greenworks Self Propelled Mower.
We hope this information helps you understand our product better, and perhaps encourages you to give it a second chance! Should you have any further questions or warranty needs, contact us through Live Chat on www.greenworkstools.com or call Greenworks toll-free helpline 1-888-909-6757. We would are here to help.

Easy to use mower
on May 26, 2025

from Fort Collins, CO

[This review was collected as part of a promotion.] This mower has plenty of battery to mow my small yard on one charge. Its easy to use and i like being able to adjust the walking speed, as i like to walk at a brisk pace. The turbo power was a great feature when mulching leaves.
I would recommend this to a friend!

Battery life and design are a problem
on July 13, 2025
Posted by: Dkay
[This review was collected as part of a promotion.] I bought this mower last July and have used it since then. The self-propelled sliding handle is awkward and uncomfortable, but the real problem is the batteries. The batteries started lasting shorter and shorter times. The manual says not to fully exhaust them or this can happen. But there is no way to tell what charge remains in the batteries as one mows, and the mower fully exhausts one battery before switching to drawing power from the second battery. Seems like it was designed to make you have to buy more batteries. BUT the battery I need (so I can switch out three of them) is out of stock. Very frustrating. Buy something else.

Hello Dkay.
Thank you for bringing your concerns to our attention. Greenworks batteries typically feature a Battery Capacity Indicator (BCI) button that allows you to check the remaining charge.
Here's how to check the battery.
Locate the BCI button. This button is usually found at the end or on the front of the battery pack.
Press the button firmly. You may need to apply a direct push with the tip of your finger.
Observe the indicator lights. A series of green lights will illuminate, indicating the remaining charge level. The lights will remain lit for a few seconds before automatically turning off.
Battery charge levels
3 Green Lights: 80-100% capacity.
2 Green Lights: 50-80% capacity.
1 Solid Green Light: 20-50% capacity.
1 Blinking Green Light: 10-20% capacity.
No lights: Under 10% capacity, requires immediate charging.
We hope you will find this information useful. If you need any further support, our team is available to assist you. You can connect with us through Live Chat on our website at www.greenworkstools.com, or by phone at 1-888-909-6757.

Frequent Problems
on July 23, 2025
Posted by: DisappointedCustomer547
from Northwest Arkansas
Gender:Male
I live in a hot and humid area of the United States and this mower frequently stops from overheating or stops due to our thick grass. It seems like there is an issue every 5 minutes or less with this mower. Because of this, it takes me multiple DAYS to mow my 1/2 Acre lawn. It is frankly ridiculous. Additionally, I do not use the self-propel feature, because the batteries already die so fast that it is not worth the extra power drain. I've used gas powered mowers of similar price-range and never had any issue like this before.
This lawn mower is weak, poorly engineered, and not worth the price they are asking for it. I will not be purchasing another electric lawn mower from Greenworks ever again.

Hello DisappointedCustomer547.
We are sorry to hear that the included 40v Mowers' battery runtime does not meet your expectations. As we are not sure of the condition of your lawn, we are not exactly sure why the battery did not meet your expectations. The maximum runtime often applies to a flat, open yard. Slopes and obstacles require more power, and users can expect running time to be less, if this is the case. Runtime measurements are also related to the condition of the grass and if it is well-maintained. Tall, thick grass requires more power, and you must mow it slower, consuming added runtime. Here are a few tips to ensure the max runtime is achieved. Ensure you charge the battery fully before each use, maintain the battery properly by cleaning terminals, avoid extreme temperatures during storage, consider buying a second battery for larger lawns, mow in a straight line, and choose a mower with a powerful battery suitable for your lawn size. If the grass has been left to exceed four inches, we advise that you raise the cutting height and cut no more than one-third of the length of grass at a time, wait a couple of days and do another one-third, cut when grass is dry and walk at steady pace to allow the blade to work more efficiently. As the lawn becomes consistently maintained you will see the cut and runtime improve. Hope these tips help! If you ever have specific questions or concerns about our products, contact Greenworks via Live chat on our website (www.greenworkstools.com), 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.
