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.

  • The 40V mower can be a better fit for larger yards because it is wider and may reduce the number of passes needed.

  • The deal can be especially attractive for people who already own Kobalt 40V tools because the included battery can expand a 40V attachment ecosystem.

  • Store pickup can work smoothly when inventory is available, with units reportedly ready for pickup after purchase.

  • The mower can work well for small yards, with at least one report of no technical problems over under two years of use.

  • Price and availability can be inconsistent, including reports of orders canceled for price mistakes and stores showing much higher in-store pricing than the online deal.

  • Some stores may refuse to honor the app or online $99 price even when the site shows the lower amount.

  • The deal can expire quickly, and the mower can later show a much higher list price such as $529.

  • The mower may not be self-propelled, which can conflict with expectations for a self-propelled model.

Yes. I also found one that was marked out of stock, went to ring it up and it was $329. I showed them their app showed $99, and the store manager came up and refused to sell it to me for $99. He stated that he would put it aside, and took down my phone number, and said he didn't want to get in trouble for selling it for $99 and said once he heard back from corporate, he would call me. I never got the call back, I am sure he took it for himself, such BS... As of today, it still shows $99 on their site.

IDK, they cost $329 at the store, so less than that. Not sure how many people are looking at FB marketplace right now for lawnmowers.

wanted one for my rentals as Im bringing all my kobalt stuff there and replacing it with 40v ryobi yard stuff for myself i was getting on clearance everywhere. I will say tho I have had a ton of this kobalt stuff now for years and it takes a beating and I love it.
Found the LAST one in a lowes near my rentals but for 200$ and I still thought it was worth that but some butthead stole the battery. I have a ton of the batteries already and they marked it to 50$ bucks for me!

you should have called corporate there with him. never trust the employees. I had gotten a great generac generator at HD from 600 to 200 on clearance. I will usually do a will call pickup but all the employees refused to do it for me so I bought it and shoved it in my work car out of spite. I do will calls all the time and I wanted to use my truck. finally 2 of the employees said they wanted it for themselves. this is also why i had to teach my wife to NEVER call the store and ask if an item is there. you are basically showing them the thing they will buy and tell you they dont have it
