Some Assembly Required – But Not Much

The box arrived in our driveway a couple of weeks ago – one day after the last cut, of course, so we’ve had to allow a little time for watching the grass grow before we could really put it through its paces, and see if it makes the cut. It’s fairly large and a bit unwieldy, so if you’re not having it delivered, bring a friend when you’re picking it up at your friendly neighborhood Lowe’s. The box isn’t overly heavy, but it’s a bit large to comfortably carry yourself.

Actual setup of the Kobalt 24V Cordless Mower is simple. As mentioned, get your batteries charging right away. Like most devices these days, they’ll arrive with only a partial charge. Unlike the 40 Volt Kobalt line of tools, which are also great options in the yard care department, these batteries will work with your standard suite of Kobalt 24 Volt tools.

If you’re already on that platform and in the market for a Battery Powered mower, then this one is really a no-brainer since a pair of batteries alone, with no charger, will run you almost half the cost of the Mower package with the batteries and charger included.

While the batteries satisfy their lust for power, remove the bag and bag frame, then carefully cut open your box and wheel the mower out. It takes a few minutes to clip the bag on to its frame, but that’s about all of the assembly required to get up and running. After that it’s a quick task to slide the release bars and unfold the handle frame, then unclip and extend the handle to its full length.

Note: the manual does state that the mower will not operate unless fully extended. You do have a couple of detents from which to select on the handle bar height, so it should allow folks of various heights to comfortably operate the mower while keeping the handle fully extended.

At this point, remove the mulching insert and slot your bag in to its proper place on the back of the mower. Alternatively, you can attach the included side chute if you don’t feel like dealing with bags full of cut grass at the end of the day.

Note: you should be doing all this without the batteries inserted – no one wants to lose a hand. Although I guess it’s a good excuse not to get the lawn mowed, it’s not one we here at Home Fixated recommend!

Firing Up The Kobalt 24V Cordless Mower

Depress the Start Button (and keep depressing it – don’t just push it and let go), then pull down the upper bar on the handle. This will start the blade turning and off you go. The bottom bar can be pulled up to activate the self-propelled function, and a small lever on the left can be pushed forward and back to adjust the speed of the self propulsion unit – much like I’m sure it works on the Star Ship Enterprise, or a boat throttle, but I don’t have a boat or starship so this will have to do for now.

The self-propelled function will actually work regardless of the blades spinning, so you can safely drive around your self-propelled mower, for example from the garage or shed to the actual grass, without spinning the blades. This eliminates worrying about shooting that little screw that you never did find after the last job across the yard, or into your car, or window, or neighbor who was not standing the minimum 100’ distance away.

Once you’re ready to get going, check the height of your cut. It’s an easy adjustment, with a lever at the wheel on one side only that sets the deck height for the whole machine – pretty standard stuff for most modern mowers. The Kobalt’s is easy to operate and convenient.

Next step, make sure all humans, pets, insects and all other living things are at least 100’ from the area of operations. If they are not, call it a day, grab your favorite beverage and wait for another day when no living organisms exist within or near your work space. Assuming you have achieved the proper safe distance, fire up your mower using the steps listed above and off you go!

Ready, Set, Mow!

It should be noted that the mower itself is very light and easy to handle. It’s a composite of metals and plastics, and the lack of a gasoline engine and fuel tank work to shave quite a few pounds off its comparably sized gas-guzzling mower brethren. It would not be a bad mower to use even without the self-propelled function, but it’s definitely a real plus in getting up hills and keeping your pace up. It’s likely that it impacts the speed with which you drain the battery, although it wasn’t an issue for me, as even our upgrade Covid yard still isn’t all that big.

Another advantage to the Battery operation is the noise. The blades still spin, and that does account for some noise, but nothing near the standard sounds of engine and exhaust noise from gas operated mowers. My neighbors have already commented on how quiet it is in operation…I have a feeling I may be seeing more of these battery-operated mowers in a yard near me soon! Here’s a brief mower’s-eye view of me attacking the dandelions with the Kobalt 24V cordless mower:

Getting Past The First Cut

To make sure I put The Kobalt 24V Cordless Mower through it’s proper paces (and not at all because I’m lazy), I let the grass grow for about 12 days from the previous cut. That may not sound like much, but with the unseasonably warm spring we had, there was a decent amount of grass. I’m also trying hard to eradicate a dandelion infestation, so in the front yard I set the mower to the lowest setting and bagged up the clippings to hopefully prevent re-seeding (spoiler alert – I still have dandelions). So I did get to give the mower a good run through.

The mower fired up great and tore through the relatively thin and lower grass of the front yard with no problem. I bottomed out a couple times, particularly around the edges of the yard where the wheels sank lower, and it wasn’t helped by the low deck height either. That said, this would happen with pretty much any mower. In the few thick parts, you can actually hear the mower blades ramp up when you get to thicker parts of the yard. It’s a nice feature to help you power through the tough stuff, while keeping drain on your battery minimal when the cutting is easy.

After getting through the front with relative ease, I dumped the mower bag, added the mulching attachment and spreader chute for a test, and went to work on the backyard. I set the deck to what will be my normal height of 3”, and quickly tore through the whole backyard with minimal slow downs or bogging out.

When I was done mowing what is a little under a quarter acre (~9,000 sf. of yard area), in about a half hour, there was still about 2 bars left of battery life – which is simply unacceptable! We have to see how long it takes to kill these things. So, I lowered the deck height to level 2 and re-mowed the back yard, chewing up previously spit out grass along the way. The mower did start to bog down, more from a combination of running over already mown grass and the unevenness of the soil in the backyard.

After that effort, we were down to 2 bars and a little over 40 minutes of runtime…so I lowered the deck once more and went at it again. I finally did get the batteries to run out on me after a little more than 50 minutes of run time, much of which was spent on the lowest deck height, with the self-propel on and cutting through significantly thick grass and previous trimmings. My best guess is that on a normal run at a regular deck height, you’ll easily achieve The Kobalt 24V Cordless Mower’s maximum run time of 60 minutes.

Battery Life is Good Enough for Our 1/4 Acre of Lawn

The single most important question we ask when we’re considering a battery-powered lawnmower is, How long will the battery last? Lowe’s says you get up to 80 minutes of runtime with this lawnmower. We’ve used the mower twice now to cut our lawn (each time removing approximately 3″-5″ of grass height), and it has been able to complete our quarter-acre yard without stopping in about an hour, leaving just 1 bar (out of 4) on the battery remaining. Given that we were down to 1 bar after a 1/4 acre, we suspect you’d need two batteries for anything larger than about one-third of an acre.

Battery Charge Time Is Just Over an Hour

A full charge requires an hour and fifteen minutes, but you can get over half charged in about 30 minutes. Still, this is probably a little too long for most people if you’re trying to use the same battery twice for one job. If you spring for the second battery (a fairly pricey option — see the price section below), you’ll get virtually uninterrupted mowing since the charge time is about the same as the run time.

Here’s a picture of the battery on the included charger.

One really nice feature about the KOBALT is the ease of deck height adjustment. The mower has 7 settings (ranging from 1-3/8″ to 3-3/4″). Instead of needing to adjust height on each of the 4 wheels, you pull one lever (and it’s easy to move) and the entire mower adjusts. You can see the lever over the rear right wheel here.

Solid Mowing Performance

So far, the mower has performed great for us! We’re super pleased to finally be off of gasoline and the associated hassles of engine maintenance, oil, and regularly hauling gas cans to/from the gas station. We usually cut our grass when it’s 3-5″ higher than we like it – so the KOBALT is removing a fair amount of grass height for us.

It probably goes without saying, but the best part of owning a battery-powered mower is the elimination of gas and oil from the setup. No more trips to the gas station with gas cans is a really nice thing. The only regular maintenance this mower requires is blade sharpening, which you should be doing on your gas mowers anyway, but which is more important on this mower since dull blades can negatively affect battery life. If you’ve never sharpened a mower blade, it’s simple and you can follow that link for tips.

Price Recommendation

The KOBALT 80v Max Mower comes in two varieties, the standard push mower (shown in this article) which retails for 499, and a self-propelled version of 599. Here’s the links for both.

You can also purchase the mower without a battery or charger (currently 329 for this option which makes sense if you have other KOBALT tools already)

Perhaps the biggest drawback of all these large battery tools is the price of extra batteries. A second 6.0Ah 80v Max battery runs a whopping 229. We know there’s a lot of technology that goes into these batteries and we are hopeful that will come down on them. That said, this battery replaces hundreds of gallons of gas you’d otherwise have to buy, so in that sense the pricing isn’t insane.

After just two rounds of mowing with the KOBALT we can definitely say it’s a huge improvement over our gas mower. The major pluses are elimination of the need to keep gas on hand and the instant-on nature of the mower (no gas means no choke/start-up activities). We recommend this mower to anyone looking to cut out the gasoline.

Kobalt 80V Self-Propelled Mower Review

kobalt, cordless, mower, review

Kobalt does a lot of things right in the design and performance of their 80V mower. With cutting area being the only chink in its armor (and a small one at that), it’s proving to be a significant player in the upper tier of battery-powered lawn mowers.

Kobalt 80V Mower Covers a Lot of Ground

We tested out a whole mess of mowers recently—both gas-powered and battery-powered—to see what the state of mowing looks like these days. One of the really impressive models we had the opportunity to check out was the Kobalt 80V self-propelled mower, which is a Lowe’s exclusive.

Both models have a large label on the rear bag door area with a serial number, model number and date code. The Kobalt brand mowers also have an item number on the label. “Kobalt” or “Greenworks” is printed on the side of the bag.”
