What Customers Are Saying
The electric mower offers quiet and easy operation with self-propelled features. It provides good battery life, allowing most users to complete their yard in one session. The mower is lightweight and maneuverable, handling moderately tall and thick grass well. However, it may struggle in very tall, thick, or wet grass, and the self-propelled feature can be difficult to control at times. Some durability concerns were also reported, with issues like broken parts after a year or two of use.

I bought my mower and weed eater combo at the end of the 2025 season. I absolutely love it. It takes me about 75 minutes to mow my grass and the batteries hold up great. I do push it the majority of the time versus using the self propelled function, which by the way works really well also. The only time I have had trouble is when I get behind on mowing and the grass gets very long. It lacks enough power to pick the grass up and cut it, unless I make two passes. Overall I look forward to the gra...

Great design poor quality
I love the mower I love its ability to cut grass, fold up, and swap batteries with all my other 20+ tools. But good grief. in 3yrs its been replaced twice and broken a multitude of other times. The height adjuster spring flew off. The battery lid broke off. The electric motor locked up. The locking mechanism on the handle broke and now the slide in feature on the handle is worn out and keeps shutting down the mower. I have a small city lot and mow 2 times a week less than 45 minutes each...

Worked great until recently
We bought this mower spring 2023 so its 3 years old. Worked great until recently. Its developed s repeated shutdown behavior. Any increase in load on the motor, even, very momentarily, shuts the motor down. There must be a timer as it will not restart until i wait 30-45 seconds. Ive used ChatGTP to research: "And I found something that makes me take your symptom more seriously: the owner's manual specifically describes mower-overload protection, and the Lowe's listing currently has other...

mower keeps stalling
I was so happy with my mower in the beginning. Now it stalls constantly. I have since found out it was discontinued. All the associate said was there were problems. It didn't come with a manual. I purchased spare batteries, new blades (the website says there are no blades available for my 20inch 48v mower), and I empty the bag exceptionally often. The website is not offering any insight to the problem. If this is a warranty issue I would like to know before it expires.
Hi there, Bob! We're sorry to hear that your mower's performance has changed over time and that you're experiencing frequent stalling. We... Read More

Poor mulcher
Mower is light, works OK and battery life is good for my small lawn. It does not mulch well at all. Blade design provides no lift. It barely lifts large dry leaves off the lawn to be munched. I have not been able to find a suitable improved blade that will fit.
Light mowing only! Simple mulch mower.
First, I decided to buy this mower because it said "rebates" available but after buying I saw the rebate that I did not qualify for ($174 rebate). That was disappointing but likely my fault for leaving an old zipcode in my browser cache. I waited until I had a chance to mow 2 times before I was ready to write about this mower. This mower is only good for shorter, dryer grass, and mulch mode of cutting. I tested it out, excited that my lawn could be bag mowed, and was a 100% failure. I mowed w...

Awsone !
I am so happy to have this mower. Everything about this mower is easy. Easy to use, store (the way it breaks down), to use, so light weight for the monster it is. Comes with two batteries that, for me, they lasted for over 2 hours. It runs, pretty much on its own, I just have to direct it. A lot of my cutting is on hillside, and this mower is a blessing. Going back up the hill to put it away I just hold the one lever and walk along with it. I highly recommend it, especially here on Earth Day. T...
Does the job
Got tired of spending $$$ on repairing gas mower. I have lot of other Kobalt 24 volt tools so all the batteries are compatible. Cut nice but don't let the grass get to thick, it will stop. If it had a couple more hundred RMP then probably do better (only reason didn't give it 5 stars). All in all does the job.
48v mower
5 yr warranty is a plus. Mower quit working after a year. Kobalt gives a return code for warranty at local Lowes. This is not a replacement, you will have to purchase new mower again, otherwise pricing from a year ago is refunded!!

This is the mower for you if: - You’re a boomer who has nothing else/better to do with your time than mow your lawn three times a week so there’s never really much to mow. - You want to revolve your entire day around mowing (because you’ll start in the morning, the batteries die, you have to spend three hours charging them, then hopefully complete your yard work during the second round, if you’re lucky) - You live in the desert with little to no grass. - You live in a “patio home” with a yard t...
