Community Reviews

This Kobalt 40V 20-inch mower is mainly attractive as a budget-friendly way to get a 6Ah battery and build into the 40V tool ecosystem. The wider deck and stronger 40V setup suit larger yards better than 24V models, while the battery alone is seen as worth a big share of the price. Small-yard owners report solid performance and no technical issues. The main caveat is that the listing and store pricing have been inconsistent, and the mower is not actually self-propelled. It is a better fit for modest lawns or battery buyers than for anyone expecting a premium mower.

Common Questions (5)

Sometimes the store can manually match the online price, but not always. Some shoppers got the price adjusted to $99, while others were told the store could not match it and saw higher in-store prices like $317 or $329.

Yes, if you already use Kobalt 40V tools, the included 6Ah battery can make the deal worthwhile on its own. The mower plus battery is also a strong value at $99, especially since the battery is often valued near or above that price.
Toller es1017 blingkblingk beachtrax
Yes, some stores still had units available even when the listing showed expired or sold out. In-store pickup and in-store purchases were still possible in several locations, though availability and pricing varied by store.
demigo SharpChannel3878 JDS1000 bobdole42
It is better suited to a larger yard than a 24V mower because the 20-inch deck covers more ground and the 40V setup offers more power. For a reasonably big yard, a smaller 16-inch 40V mower can take forever, so this size is the more practical choice.
40long Toller
No. The listing title can be misleading, but this mower is described as a push cordless mower rather than self-propelled.

Depends on your yard size and need. The 40v is the more "normal" sized mower. It is wider (less passes) and I would think offers more power than the 24V. It is better to have more than one battery to be stuck if the single battery overheats, but you can accumulate more with the other attachments- weed eater/leafblower/etc

I have a 40v Kobalt 16" and it works fine. But I use it for a tiny area. If you have a reasonably big yard, it will take forever. Definitely swap it out. And 24v mower is a bad idea.

The reviews aren't all that bad. And it is $99 dollars! The battery is worth twice that much. I have tempted to get it, but I don't need a mower and really don't need a battery either.

Buy it, easy return if you decide not to keep it.

Insane deal for people who already have 40v items. I bought two just for the batteries. NOT expired in CT as of 12:30.

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