Kobalt's 80V self propelled mower is being treated as a strong cordless option for yards that need more than a basic push mower, with clean cuts, good power, and noticeably quieter operation than gas. The shared 5Ah battery system is a plus for owners who already use Kobalt 80V tools, and the mower is described as easy to use once the rear wheel drive behavior is understood. Battery life is the main watchout, especially in thick grass, hot weather, or larger yards, where extra batteries may help. The deal also drew price adjustment and rebate chatter that could bring the cost down further.

Common Questions (6)

  • For a tiny, perfectly flat lawn, the self-propel feature may be unnecessary because the mower is light enough to push. On hills or even small inclines, self-propelled assistance is useful and a push-only mower can become tiring.

  • A price adjustment has been credited after buying the mower at a higher price, including a $409 purchase that was adjusted to the lower sale price. One adjustment was done through online chat for $30 back, while another attempt was reportedly denied, so results can depend on the channel and agent.

  • The batteries are warrantied for 3 years, and real-world life is often around 3-5 years depending on use and climate. Thick or tall grass drains them faster, and keeping blades sharp, the deck clean, and mowing more often helps extend runtime.

  • The self-propelled version is useful on hills and in hot weather, and the mower can deliver clean cuts with enough battery life for a typical yard. In soggy spring conditions or very tall grass, electric mowers can stall more easily and battery life drops faster.

  • Yes, the 80V 5Ah battery can be shared with other Kobalt 80V tools such as a string trimmer. That makes the mower more useful if you already own or plan to buy other Kobalt 80V equipment.

  • Yes, it is much quieter than gas mowers and can still be quieter even when running alongside one. That makes it a better fit for noise-sensitive neighborhoods.

I also bought it for $409 and was told I couldn't get a price adjustment. Did you do it at the store or online?

One thing I noticed is there is big noise when the 80v battery is charging, is the fan cooling the battery?

I also tried online, but they refused. Maybe I should print out my receipt and head to the nearest store.

Good luck, but I am Ok even if they refused, this is still a fantastic deal at $409

80v mowers are well worth the premium. They plow through everything a gas mower can, and often better. I've had the Kobalt 80v mower for years and it's held up great.

Bought this and have cut the yard twice so far. Once getting used to the rear wheel self-propel needing a small amount of disengagement time, can say I'm happy with the purchase. Clean cuts and sufficient battery life.

Get an extra battery. Mine have deteriorated quickly. It now takes me 3 batteries to finish a yard that used to take one. This is the start of the third year owning the non-self propelled model.
Thanks, that's what has deterred me from going battery. My 25 year old gas still going, but starting to kind of sputter a bit (even after tune up, think it needs a new carb or rebuild carb), and deck is starting to rust out.

My yard is small, and have several outdoor outlets in the yard. I might take a look at Corded Electric. I know it is a bit of a hassle with the cord, but would be cheaper and would basically last forever.

Save yourself the $80 and get the non-propelled version with identical battery. It's so light that there is no need for the assistance.
I would agree ,and less things to brake .

How is the battery life if you have this?
Thanks

Looks like the entire line on sale. Extra Battery is on sale for $79.

All my equipment is gasoline now. Anybody know about how long the batteries last before going bad? I live in a hot climate that tends to eat batteries for lunch. Even car batteries don't last more than about 3 years here.
I have a 9 year old 80v kobalt mower, and still using the original batteries. They definitely die much faster now, however I moved from a small lot to a 1/3 acre.

I have 3 batteries so I'm able to use one, charge and continue on and finish my yard on 5 batteries, but they're 2ah to begin with.
