What Customers Are Saying
Customers overwhelmingly praise this electric riding mower for its quiet, near-silent operation and elimination of gas and oil maintenance. Many report successfully mowing three-quarter to one-acre yards on a single charge with 50-70% battery remaining, and appreciate the fast recharge time under four hours. The comfortable seating, smooth handling, 42-inch deck, tight turning radius, and intuitive controls are frequently highlighted. Reviewers love the low-maintenance nature and adjustable blade and speed settings for different grass conditions. A few note concerns with battery drain on large hilly yards and limited accessory availability, but most consider the overall experience modern, enjoyable, and superior to gas alternatives.
Customer review summary generated by AI, including incentivized reviews.Kobalt electric 42" tractor + Ego mulch plug
This is a perfect gas mower tractor replacement. It is an effective, intuitive, and efficient machine. With regard to the Kobalt mulch plug that is not available: the Ego AMP4200 mulch plug fits the Kobalt 42" electric tractor perfectly and the discharge chute flap behaves exactly like the Greenworks setup, staying safely out of the way in the upright position without needing any modification or removal of the flap as I'd previously intended.

buy this now
I bought this earlier this week. It was delivered yesterday and I did my first mow on 7/4/26. I upgraded from a battery-powered ryobi riding mower and I could not be more pleased. This sucker feels solid and has some girth and oomph. IIt feels significantly beefier than the ryobi which 'died' last week for the third time in two years 👎 The site says it takes four hours to fully charge but it seems closer to 1.5-2 hours. If you're on the fence about purchasing yours, get off the fence and go to ...
Great Mower!
Great mower. Basically zero maintenance. Powerful, fast… cut my yard in record time. Easy handling. Tight turn radius. Automatic, push button convenience. Wife loves it too. It’s quiet, convenient, comfortable. Definitely worth every penny. Glad I took a chance and didn’t buy the well known Green Brand.
Gentle mower
I like that it’s quiet and doesn’t leave me feeling beat up after I mow. Slow speed and seems to make lots of noises when I run over small sticks.

Big Difference from Gas Mower
The 3 main differences are sound, comfort and cut width. I have a Cub Cadet over 50", which I have no complaints other than I'm getting too old and lazy to do maintenance. The Kobalt 42" is narrow enough to fit where my Cub couldn't go so I had to use a walk behind. Two things I would change is how the hood for the storage compartment opens. It would be more useful opening from drivers end to front so you can have access while cutting. Second and most important is the seat, it's no comparison to...

Not Supported
I purchased this mower with the intent to mulch my lawn. At the time I purchased the mower, the mulching kit was not available, mulching blades were not available, and a bagging system was not available available. Nobody could tell me when these parts would be available. As a result, I returned the mower and got a more dependable and supported mower. A John Deere. The mower itself was great. I just wish the support system was in place before they started selling the mower.
This was a reasonably affordable option for an all-electric mower. It seems to be made by the same company that manufactures the more expensive green brand. I love that I don't have to deal with messy oil or gas, or small engine maintenance. It zips around and cuts the grass on my 3/4-acre yard very efficiently on a single charge. I'm able to use low blade speed in most of the yard and kick it up to high speed for the thicker parts. A couple of complaints: Whoever assembled it put the steering ...
