What Customers Are Saying
The product offers good power and quiet operation, with a satisfactory battery life for small to medium-sized yards. However, some users experienced issues with the self-propel function and found it underpowered for thick or wet grass. There were also complaints about the availability of replacement parts and difficulty of cleaning the mower.

Brand new first time it cut our .25 acre lot with about half battery life to spare. Ever since then it won’t cut without at least one charge about 75% through the job. Now I either have to return or buy separate battery (another $80 to $100). Buyer beware. Not a quality product.

I trimmed down the top of the switch and viola! everything worked as one would expect. I hope Kobalt reads this as a sticking power-drive switch is DANGEROUS. Other than...

Zero Star- Customer Service Rating
I have had my Kobalt 80V mower for over 7 years now and rate the mower itself as a Five Star. It still runs great, and the identical new mower is still available. But this year a rear wheel fell off. The warranty expired over two years ago now so no big deal, I figured I'll just buy a new set of wheels. I called Kobalt customer service and after wrasseling with a bot for too long a talked to a human being who told me, "We don't support repair parts." I then called customer service at the Lowes...
