Community Reviews

This Kobalt 40V 20 inch mower stands out as a cheap way to get a 6Ah battery and a usable mower for small yards or existing 40V tool setups. The wider 40V platform is described as better for larger yards and more power, and the battery alone is treated as a big part of the value. The main caveats are that the listing is inconsistent, with some stores showing higher in store prices, cancellations, or stock issues, and the mower is not actually self propelled. It reads like a strong battery bundle with mower attached.

buyers shopping for a small yard or small trimming area, because commenters reported their 40V Kobalt 16"/this mower works perfectly for a small yard and that it's a great deal for very small areas.
BaseShip beachtrax Toller
homeowners with reasonably big yards who want fewer passes because the 40V mower is wider and has more power than smaller 24V options, since commenters said it would take forever with a smaller 16" 40V for big yards.
40long Toller
people who already own Kobalt 40V tools and mainly want an extra battery for their existing ecosystem, because commenters said it's an "insane deal" if you already have 40V items and that buying it for the batteries alone is a great idea.
es1017 beachtrax
people who can use store pickup and want to confirm inventory quickly, because at least one commenter said they bought two with store pickup and confirmed they were ready for pickup.
SharpChannel3878
electric-lawnmower rebate applicants who can submit paperwork after purchase, because one commenter received the mower and was able to submit it for a $50 electric lawnmower rebate through their utility company.
Savinginthe802

shoppers who need the $99 price to be honored without in-store price matching, because multiple commenters reported stores showing a much higher price (e.g., $317/$329) and said you have to go in and get price matching.
bobdole42 shinseiRomeo JDS1000
buyers expecting a truly self-propelled mower, because one commenter said "This one is not self-propelled," despite the listing being described as self-propelled.
pur
people with a reasonably big yard who are considering a smaller 16" 40V Kobalt instead, because commenters said it works fine for a tiny area but would take forever for a reasonably big yard.
Toller
buyers who can't handle deal inconsistencies like cancellations or price mistakes, because one commenter said their order was canceled due to a price mistake.
Convit161
people who want top-line performance/quality for the money, because a commenter cautioned not to expect much and said the performance/quality aligns with the price.
nolenski

The 40V battery mower can cover larger yards with fewer passes and more power than smaller 24V options.
40long Toller
The deal can be especially useful for owners of existing Kobalt 40V tools who want extra batteries for attachments.
40long beachtrax
The included 6Ah battery can make the $99 price feel compelling, especially when the battery value is considered separately.
blingkblingk Toller
Store pickup can work smoothly when inventory is actually ready for pickup at the local store.
SharpChannel3878

In-store pricing can differ sharply from the online $99 listing, and staff may require price matching or refuse the lower app price.
bobdole42 shinseiRomeo ktop4u ihateu3
The mower may not be self-propelled, which can reduce convenience if you expected self-propelling performance.
pur
Some orders can be canceled due to price mistakes, which can derail the $99 deal before pickup or delivery.
Convit161
The mower's performance and quality may not meet expectations if you buy it expecting top-line results.

Common Questions (5)

Sometimes, but not always. Some stores reportedly matched the $99 online price at the register, while others refused and said they could not match it or showed a much higher in-store price.
shinseiRomeo shinseiRomeo ktop4u ihateu3
Yes, if you already use Kobalt 40V tools. The included 6Ah battery is viewed as worth about the purchase price on its own, making the mower a strong value even if you mainly want the battery.
Toller es1017 beachtrax
Yes. It has been reported to work perfectly in a small yard with no technical problems for under two years, and it can be a good fit when the cutting area is small.
BaseShip beachtrax
No. The listing title says self-propelled, but the mower is reported as not self-propelled, so buyers should not expect that feature.
pur
It can. One buyer submitted it for a $50 electric lawnmower rebate through a utility company after receiving the mower.

This one is not self-propelled. Unfortunately it seems like the deals are only available in some locations.

Thank you OP! Just bought two at my local store. At first they tried to argue the price saying online only a lead manually changed the price to match. .

Having it for the batteries alone is a great idea like someone else pointed out just to use on their already good 40v units. But some people have a very small area to trim so for them this is a great deal.

75% off. $100 for a 40V mower with 6ah battery is a steal. Even though the mower isn't a top line choice

I have this for less than two years. I have a small yard, and it works perfectly for me. No technical problem at all with it.

Could you just go in store and buy it? That's what I did.
