Key takeaways
- Pro: 18-inch deck saves time over narrower competitors at this price
- Pro: Brushless motor for better efficiency and durability
- Con: Battery inclusion is unclear from the listing
Buyers searching for a “kobalt lawn mower” are solving a specific problem: they want to cut a typical suburban lawn on a single charge, store the mower flat in a garage or shed, and skip the oil changes, spark plugs, and pull-cord frustration of a gas machine. The Kobalt name has earned trust in this space, but by 2026 the cordless category has matured to the point where several alternatives match or exceed its value at comparable price points.
What separates the good from the bad in this class comes down to three things: whether the motor is brushless, whether the deck width actually matches your lot size, and whether the package includes a battery and charger or leaves you scrambling for an add-on purchase. The list below compares published specifications, street prices, and aggregated owner feedback across eight mowers that compete directly in the same tier as the popular Kobalt 40V and 80V models.

How We Picked
We filtered this category on four criteria: motor type (brushless over brushed for longevity and efficiency), deck width matched to realistic lot sizes, whether a battery and charger are bundled at the listed price, and platform breadth for future expansion. Owner feedback across retail listings shaped our confidence in real-world durability and after-sales parts availability.
The 8 Best Kobalt Lawn Mower in 2026
Wild Badger Power 40V 18-In Brushless Cordless Electric Lawn Mower
This mower suits homeowners with mid-size lawns who want a wider deck without stepping into premium-tier pricing. The 18-inch cut path covers noticeably more ground per pass than 16-inch models, which adds up when you mow every weekend. The brushless motor runs cooler and draws less current under load than brushed equivalents, meaning longer component life. The main drawback is that the listing does not confirm a battery or charger in the box, so budget accordingly if you lack a compatible 40V pack.
- Pro: 18-inch deck saves time over narrower competitors at this price
- Pro: Brushless motor for better efficiency and durability
- Con: Battery inclusion is unclear from the listing
Skip this if you want a true all-in-one purchase or if your yard is narrow enough that a 16-inch deck handles it fine.
Cordless Lawn Mower, 17 In Walk Behind Lawn Mower for Yard & Garden
At $139.98 this is the entry point on the list and the obvious choice for small yards or anyone replacing a broken gas mower on a tight budget. The 17-inch width sits between the 16-inch and 18-inch options, making it practical for layouts with garden beds and obstacles. Its lower price means build quality and motor sophistication trail the brushless models above, and the listing does not specify battery inclusion.
- Pro: Lowest price by a wide margin in the group
- Pro: 17-inch deck is a versatile middle width for irregular yards
- Con: No brushless motor and no confirmed battery in box
Skip this if your lawn exceeds roughly half an acre or if you need brushless durability for heavy, damp grass.
Greenworks 40V 16in Push Lawn Mower, 4.0 Ah Battery and Charger
Greenworks ships this mower with a 4.0 Ah battery and charger, so you unbox, charge, and mow the same weekend with zero extra purchases. The 16-inch deck suits lawns under a quarter-acre, and the Greenworks 40V platform has broad parts availability, making future replacements easier than with the lesser-known brands here. The trade-off is deck width: 20 or 21-inch models finish open stretches considerably faster.
- Pro: Battery and charger included at a mid-tier price
- Pro: Established platform with wide parts and battery compatibility
- Con: 16-inch deck is slow on large open lawns
Skip this if your yard is larger than a typical small suburban lot or if you want brushless efficiency.
Greenworks 60V 21in Push Lawn Mower, 5.0 Ah Battery and Charger
This mower is built for large, open lawns where a wide deck saves real time. The 21-inch path paired with a 5.0 Ah battery provides the highest runtime figure listed among the push mowers on this page, which is the deciding factor for yards past a half-acre. At $389.99 it commands a premium, but the bundled battery and charger mean no surprise add-on costs. The con is bulk: a 21-inch deck is heavier and harder to store in a tight shed.
- Pro: 5.0 Ah battery gives top runtime in the push category
- Pro: Everything needed is in the box at a fair per-include price
- Con: Large and heavy, awkward for tight storage or cluttered yards
Skip this if your yard is small, your storage is cramped, or you need self-propelled assistance on slopes.
Greenworks 48V (24V x 2) 20in Push Lawn Mower, (2) 4.0 Ah Batteries Kit
The dual-battery architecture lets you run one pack for a quick trim or install both for a full mow on a medium-to-large lawn, and you can stagger charging to avoid dead-end sessions. The 20-inch width handles moderate obstacles well without the bulk of a 21-inch deck. The drawback is price positioning: at $329.99 it sits between the single-battery 16-inch and the 60V 21-inch models, so you are paying for flexibility that a small-lawn owner may not need.
- Pro: Two batteries provide runtime flexibility and staggered charging
- Pro: 20-inch width balances speed and maneuverability
- Con: Priced at a premium over single-battery alternatives with similar output
Skip this if your lawn is small enough for a 16-inch deck or if you prefer a single high-voltage platform.
Wild Badger Power 40V 16-In Brushless Electric Cordless Lawn Mower
Brushless motor efficiency in a compact 16-inch format makes this mower well suited for narrow yards, side lots, or areas where a wide deck struggles to turn. At $229.99 it undercuts the comparable Greenworks 40V push by roughly $30 while adding brushless benefits. The limitation mirrors its 18-inch sibling: the listing does not confirm a bundled battery, so the effective cost rises if you need a fresh pack.
- Pro: Brushless motor at a price below Greenworks equivalents
- Pro: 16-inch width is nimble around fences, beds, and tight corners
- Con: No confirmed battery or charger in the package
Skip this if you already own a 40V battery on a different platform or if your lawn is wide and open.
Kraftsense 21in Cordless Lawn Mower, 40V Lightweight Push Mower with 2×4.0Ah Battery & Charger
On paper this is a hard deal to argue with: a 40V brushless motor, a full-size 21-inch deck, two 4.0 Ah batteries, and a charger for $204.99. The lightweight frame makes it easier to lift into a truck or carry up porch steps than the heavier Greenworks equivalents. It competes directly with pricier models on raw specs. The genuine question mark is brand recognition and long-term parts availability compared to Greenworks.
- Pro: 21-inch deck plus dual batteries at a price under $210
- Pro: Lightweight frame for easier handling and storage
- Con: Limited brand reputation and uncertain long-term parts support
Skip this if you prioritize an established service network or need self-propelled drive for hilly terrain.
Greenworks 80V 21in Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger
This is the upgrade pick for anyone dealing with slopes, uneven ground, or simply the desire to stop pushing. The 80V platform delivers the most torque on this list, and self-propulsion removes the physical strain that makes push mowers tiring on inclines. At $479.99 it is the most expensive option, and the included battery is a single 4.0 Ah pack rather than the 5.0 Ah on the 60V push, so demanding terrain may require a second battery purchase.
- Pro: Self-propelled drive eliminates pushing effort on hills
- Pro: Highest voltage platform for consistent power under load
- Con: Priciest option, and one 4.0 Ah pack may not cover a large hillside
Skip this if your lawn is flat and open, or if your budget caps out under $400.
Buying Guide
Brushless vs. Brushed Motors
Brushless motors eliminate physical commutator brushes that wear down over time. They run cooler, draw less current under equivalent load, and typically last several seasons longer than brushed alternatives. In this price range, brushless models cluster around $170 and up. If a listing does not specify brushless, assume it is brushed and factor in a shorter service life.
Deck Width and Yard Size
Sixteen inches is adequate for lawns under a quarter-acre with tight maneuvering. Eighteen inches covers mid-size yards with fewer passes. Twenty-one inches makes sense for open stretches past a half-acre but adds weight and storage bulk. Match the deck to your longest mowing strip, not your total area, because width determines how many turns you make around obstacles.
Battery Ecosystem and Runtime
A mower bundled with a battery and charger has a clearer total cost than one that assumes you own a compatible pack. High-voltage platforms (60V, 80V) deliver more torque per pack but lock you into that voltage tier. Dual-battery setups, like the 48V Greenworks, offer runtime flexibility on lower-voltage platforms. Check whether your existing cordless tools share a battery ecosystem before committing to a new voltage standard.
Our Verdict
The top overall pick is the Greenworks 60V 21in Push Lawn Mower for anyone with a medium-to-large flat lawn, because the 5.0 Ah bundled battery and wide deck deliver the best time savings per dollar among the well-supported platforms. The budget pick is the Kraftsense 21in 40V Lightweight for the surprising spec sheet at $204.99, provided you accept the brand-risk trade-off. The Wild Badger 40V 18-In Brushless wins if your priority is the lowest brushless price with a wider-than-average deck and you already own a 40V battery.
FAQ
Are these mowers direct replacements for Kobalt lawn mowers?
They compete in the same category: battery-powered push and self-propelled mowers sized for residential lawns. If you already own Kobalt 40V batteries, verify cross-compatibility before switching platforms, as battery packs are not universal across brands.
How long does a cordless lawn mower battery typically last per charge?
Runtime depends on grass height, moisture, deck width, and terrain. A 4.0 Ah battery on a 21-inch deck in average dry conditions will cover less lawn than the same battery on a 16-inch deck, because the wider machine demands more current per revolution.
Is brushless worth the extra cost on a budget mower?
Yes, if you plan to keep the mower more than two or three seasons. Brushless motors resist the wear that eventually degrades brushed units, and they deliver slightly better torque per watt-hour, which extends effective runtime on the same battery.
What is the biggest mistake buyers make in this category?
Purchasing a mower that looks affordable at the listed price but excludes a battery and charger. Always calculate the all-in cost before comparing models, and prioritize packages that bundle both so the sticker price reflects the true total.
