Power & Performance
The MightyMow runs on a 2x20V system, effectively a 40V-equivalent cordless platform that delivers enough power for standard cool- and warm-season grasses in a small yard. Battery-powered motors at this voltage tier handle regular grass heights cleanly but may bog down in dense or wet growth , best results come from mowing when grass is dry and not overly tall.
The dual-battery setup ensures users can swap packs mid-job rather than waiting on a single charge.
Cutting System
The 16.1-inch polymer deck is sized specifically for compact spaces, letting users navigate between landscaping beds, fences, and tight corners that a larger mower would struggle with. The deck supports both mulching (recycling clippings back into the lawn) and rear bagging with a 1.41-bushel collection bin , customers specifically noted exceptional mulching performance on deep leaf piles.
The 6-position single-lever height adjustment spans 1.0 to 3.0 inches, covering most common residential cutting preferences.
Drive & Handling
At 37 lbs, the MightyMow sits in a manageable weight range for a push mower , light enough that most users won't find flat-yard mowing strenuous, though hills will require more effort without self-propelled assist. The adjustable handle height accommodates different user heights, and the foldable design collapses quickly for storage.
The 16-inch deck width means more passes on wider lawns, but in small yards the trade-off is excellent maneuverability.
Battery / Fuel
Each included 20V 4.0Ah battery provides approximately 15 minutes of runtime; using both in sequence yields roughly 30 minutes total , adequate for most small yards but below the category average of 52.7 minutes. The included dual charger allows both packs to recharge simultaneously, which significantly reduces wait time between sessions.
Because this is a battery-powered system, there is no fuel to store, no oil to change, and no carburetor to clean , start-up is push-button every time.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with small yards (under 1/4 acre) who can complete mowing well within the 30-minute runtime window
- ✓ Eco-conscious users wanting zero direct emissions and quieter operation than gas mowers without sacrificing cutting convenience
- ✓ Anyone with limited storage space , the foldable handle design compresses the footprint significantly for small garages or sheds
- ✓ Low-maintenance users who want push-button start and no oil changes, spark plug replacements, or fuel system upkeep
Not Ideal For
- ✕ Owners of medium or large yards , the 30-minute runtime (below average) may leave the job unfinished before batteries need recharging
- ✕ Users with hilly or uneven terrain , this is a push-only mower with no self-propelled drive, making slopes noticeably harder to navigate
- ✕ Those needing to cut very tall or thick grass , the 3.0-inch max cutting height offers limited overhead room for neglected or overgrown lawns
Most users report straightforward out-of-box assembly that takes under 20 minutes , primarily attaching the handle, installing the grass bag, and inserting the batteries. The dual charger means both packs can be topped off before first use.
Charge both batteries fully before the first mow , the dual charger lets you do this simultaneously straight out of the box
Set the cutting height lever before inserting the battery to make the initial height selection easier and safer

FAQ
How long does the battery last on the MightyMow cordless lawn mower?
The MightyMow includes two 20V 4.0Ah batteries, each providing roughly 15 minutes of runtime for a combined total of approximately 30 minutes. This is enough for most small yards under a quarter acre.
The included dual charger lets you recharge both batteries at the same time to minimize downtime.
Does the MightyMow come with the batteries and charger, or do I have to buy them separately?
The MightyMow comes with two 4.0Ah batteries and a dual charger included in the box , no additional purchases required to start mowing. This makes it a genuinely complete cordless kit, not just a bare-tool listing.
Can the MightyMow mulch leaves as well as grass?
Yes , the 16.1-inch deck supports mulching mode, and customers specifically noted it does an incredible job on deep piles of leaves. For grass clippings, you can also switch to the rear bagging mode using the included 1.41-bushel collection bin.
Is this mower self-propelled, or do I have to push it?
The MightyMow is a push mower only , there is no self-propelled drive system. At 37 lbs, it's manageable on flat terrain, but users with sloped yards will need to put in more physical effort.
If you have significant hills, a self-propelled model would be a better fit.
How does the cutting height adjustment work, and what heights are available?
The MightyMow uses a single-lever system to adjust between 6 positions, covering a cutting height range of 1.0 to 3.0 inches. The single-lever design means you adjust all wheels at once rather than each corner individually, which is faster and simpler to use between mowing sessions.
How compact is the MightyMow for storage , will it fit in a small shed or apartment storage area?
The foldable handle significantly reduces the mower's storage footprint , it's one of the features that sets this model apart, as only 98 of 364 mowers in the database include a foldable handle. Combined with the compact 16-inch deck width, it's well suited for small garages, closets, or tight shed spaces.
Bottom Line
The MightyMow is a practical, no-fuss cordless mower for small yard users who want clean battery-powered performance without buying batteries separately. The dual-battery, dual-charger bundle and capable mulching system make it easy to recommend for compact, flat lawns , but the 30-minute runtime and push-only drive mean it's not the right tool for larger properties or hilly terrain.
Best for small flat yards under 1/4 acre where users want zero-emissions, push-button-start mowing with everything included out of the box.
Consider alternatives if your yard exceeds a quarter acre, you have slopes that need self-propelled assist, or you regularly deal with thick, overgrown grass above 3 inches.
