The best Kobalt mower depends on the battery platform you own and whether you want a push or self-propelled model. Lowe’s listings cover 16- to 21-inch cordless walk-behind mowers, but they do not establish which cuts best, runs longest in real use, or suits a particular lawn size. Use this comparison to choose by listed specs and verify the exact model and kit before buying.
Which Kobalt mower should you choose?
| Model | Drive and deck | Battery package in cited listing | Useful distinction |
|---|---|---|---|
| Gen4 40V KPM 1040A-03 | Push; 20-inch steel deck | One 6Ah battery and charger | Three cutting modes; Lowe’s listing says up to 60 minutes of cut time. |
| Gen4 40V KSPM 1040A-03 | Variable-speed rear-wheel-drive self-propelled; 20-inch deck | 6Ah battery and charger | Telescopic folding handle; listing says up to 50 minutes of cut time. |
| 2x24V KLMS 2524A-03 | Variable-speed rear-wheel-drive self-propelled; 20-inch steel deck | Two 5Ah batteries and dual-port charger | Two 24V batteries are described as 48 total volts; compatible with Kobalt 24V Max tools. |
| 80V self-propelled | Rear-wheel drive; 21-inch deck | Not stated in the cited listing | Seven height positions and an on-board charge indicator. |
| 24V 16-inch push | Push; 16-inch poly deck | Two 4Ah batteries and charger | Mulching and bagging; listing says up to 48 minutes of runtime. |
These are Lowe’s listing specifications, not results from a standardized comparison test. The listings establish configurations, not local stock or a performance ranking. Check the exact model number, included batteries, charger, and current availability on the product page before purchase.
How to choose among the models
Start with your Kobalt battery platform
If you already own Kobalt batteries, identify their platform before comparing mower features. The KPM 1040A-03 is listed as compatible with Kobalt 40V tools, while the KLMS 2524A-03 uses two 24V batteries and is described as compatible with Kobalt 24V Max tools. The 80V mower is a separate platform; its listing does not establish compatibility with 24V or 40V batteries. Do not treat “48 total volts” on the two-battery model as proof that it works with a separate 40V or 80V system.
Choose push or self-propelled drive
The Gen4 40V KPM 1040A-03 and the 24V 16-inch mower are push models. The Gen4 40V KSPM 1040A-03 and KLMS 2524A-03 have variable-speed rear-wheel-drive self-propulsion; the listed 80V model is also self-propelled. Self-propulsion may suit a shopper who prefers powered assistance, but the cited listings do not measure effort, speed, or handling differences. Compare the drive type as a preference, not a proven performance advantage.
#1 Best Overall
- 1. Best-Fit Yard and User: For small-to-medium lawns with open grass and landscaping; ideal for users comfortable pushing who want fewer passes.
- 2. 18-Inch Brushless Cutting: Reaches up to 3,400 RPM, and the wider deck covers more grass per pass while still turning around beds and trees.
- 3. Five Cutting Heights: Select from five positions for seasonal growth, weekly maintenance or grass left longer in warm, dry weather.
- 4. Three Clipping Modes: Choose bagging, mulching or rear discharge; the included 11-gallon bag helps collect clippings for a clean finish.
- 5. 40V Battery Kit Included: Includes one 40V 4.0Ah battery and fast charger; runtime varies with grass, terrain, temperature and mowing pace.
Consider deck width and storage
The listed deck widths run from 16 inches to 21 inches. A wider deck covers more width per pass in principle, but these sources do not establish cutting speed or the best width for a given lawn. The 40V self-propelled listing describes a telescopic folding handle, and the 2x24V model has a folding handle. No cited source measures storage footprint, so check the mower’s dimensions if shed or garage space is limited.
Check cutting modes and kit contents
The KPM 1040A-03 is listed for mulching, bagging, and side discharge. The KSPM 1040A-03 and KLMS 2524A-03 are described as having three cutting modes. The 24V 16-inch listing specifies mulching and bagging. Confirm the functions and included accessories for the exact configuration you are considering, especially where product pages distinguish a kit from a tool-only mower.

What the runtime and warranty claims mean
Lowe’s current listings say up to 60 minutes for the KPM 1040A-03, up to 50 minutes for the KSPM 1040A-03, up to 50 minutes for the KLMS 2524A-03, and up to 48 minutes for the 24V 16-inch mower. These are retailer-stated maximums, not independently tested or guaranteed runtimes. The cited listings do not provide standardized conditions that would make those figures a reliable direct comparison.
Lowe’s listings for the cited 40V and 2x24V models describe five-year limited mower/tool coverage and three-year battery and charger coverage; the 80V listing describes a five-year limited tool and three-year battery warranty. Treat these as listing summaries, not universal Kobalt warranty terms. Review the manual and warranty document for the exact model to confirm duration, exclusions, and coverage.
