MightyMow 20V Brushless Cordless Lawn Mower: 13.2" Compact Electric Mower
The MightyMow cordless lawn mower pairs a brushless motor with a compact 13.2-inch deck and two 20V 4.0Ah battery packs for cord-free convenience in tight spaces. At just 33.1 lbs with a foldable handle, it's purpose-built for small yards, patios, and city lots where storage space is as limited as the lawn itself.
The dual-battery setup helps offset the modest runtime, but this mower shines brightest for homeowners who want zero-emissions, low-maintenance grass cutting without the noise or fumes of gas.

What Sets It Apart
Key specification highlights based on our analysis.
Foldable Handle
Compact storage (98 of 364 mowers have this)
Considerations
13.0-Inch Cutting Deck
Narrow deck means more passes (walk-behind avg: 18.0 in)
Polymer Cutting Deck
Lightweight but less durable than steel; won't rust
Why We Recommend It
- 01.
Brushless motor technology delivers more consistent power and runs cooler than brushed motors, extending overall mower lifespan
- 02.
Dual 4.0Ah battery packs included in the box , combined runtime potential helps cover more ground without buying extra batteries
- 03.
Ultra-lightweight at 33.1 lbs, making it easy to lift over curbs, into a car trunk, or up garage steps
- 04.
Foldable handle collapses for wall-mount or closet storage , one of only 98 out of 364 mowers with this feature
- 05.
Polymer deck resists rust completely, a real advantage in humid climates or if the mower is stored outdoors
Considerations
- 01.
13-inch deck width is significantly narrower than the 18-inch walk-behind average, meaning 30-40% more passes to cover the same area
- 02.
Battery life has drawn mixed customer feedback , individual 20V 4.0Ah batteries deliver roughly 40 minutes, which may fall short on thicker or wet grass
- 03.
Cutting height tops out at 2.6 inches, which limits options for homeowners who prefer a taller, drought-resistant lawn height

Power & Performance
The brushless motor at the heart of this cordless lawn mower runs more efficiently than traditional brushed motors , generating less heat, less friction, and more consistent torque through the full battery discharge cycle. Powered by a 20V platform, it handles typical cool-season and warm-season lawn grasses in good condition with ease, though it may struggle in dense, wet, or overgrown grass where higher-voltage systems have the edge.
The brushless motor power advantage also means the motor itself should outlast brushed equivalents by a significant margin.
Cutting System
The 13.2-inch polymer cutting deck keeps the mower lightweight and rust-proof, but its narrow deck width is the primary trade-off buyers must weigh , it's roughly 27% narrower than the average walk-behind mower at 18 inches. Cutting height adjusts across five positions from 1.0 to 2.6 inches via a single lever, which is convenient but limits those wanting to keep taller turf.
The rear-bag discharge system holds 1.24 bushels and is the sole discharge option, so mulching and side-discharge are not available on this model.
Drive & Handling
This is a manual push mower, so all forward momentum comes from the operator , a non-issue on flat ground given the 33.1 lb total weight, which is genuinely easy to maneuver around flower beds, trees, and tight corners. The foldable handle reduces the footprint when not in use and makes transport in a car or truck much simpler.
On slopes or inclines, the lightweight build is helpful, but the absence of self-propelled drive means steeper grades will require more user effort.
Battery / Fuel
The mower ships with two 20V 4.0Ah battery packs and a charger, providing up to approximately 40 minutes of runtime per battery under normal conditions. Swapping between the two packs extends usable session time without waiting for a charge cycle, which is a smart inclusion for the target small-yard user.
Customer feedback on battery performance is mixed , real-world runtime can vary with grass density, height, and temperature, so users with consistently challenging conditions should temper expectations and keep both packs fully charged before each mow.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with small urban or suburban yards (under 1/8 acre) who want a quick, easy mow without pulling a gas engine cord
- ✓ Apartment dwellers or townhouse owners with minimal storage space , the foldable handle and 33.1 lb weight make it easy to hang on a wall or slide into a closet
- ✓ Eco-conscious users who want zero direct emissions and quieter operation than gas mowers, without sacrificing effective cutting power
- ✓ Low-maintenance seekers who want to skip oil changes, spark plug replacements, and carburetor cleanings entirely
Not Ideal For
- ✕ Owners of medium or large yards (1/4 acre or more) , the narrow 13-inch deck width means significantly more passes and potentially insufficient battery runtime
- ✕ Anyone mowing hilly or uneven terrain who would benefit from a self-propelled drive system, as this is a push-only model
- ✕ Homeowners with thick, overgrown, or consistently tall grass , the 2.6-inch max cutting height and modest 20V system may bog down in heavy conditions
Cordless electric mowers in this category typically require minimal assembly , usually attaching the handle, installing the grass bag, and inserting a charged battery before first use. The foldable handle design means no tools are required for storage configuration.
Charge both battery packs fully before the first mow so you have maximum runtime available from the start
Fold the handle down immediately after each use to build the habit and keep your storage space clean
Warranty details for this MightyMow model should be verified directly with the manufacturer or retailer at the time of purchase, as coverage terms can vary by region and seller. Always register your product after purchase to ensure warranty claims are processed without delay.
FAQ
Does the MightyMow come with batteries, or do I need to buy them separately?
Two 20V 4.0Ah battery packs and a charger are all included in the box , no separate purchase required. This is a meaningful value add, as replacement or additional battery packs for 20V cordless platforms can investment - each at retail.
How long does each battery last on a single charge?
Each 4.0Ah battery offers approximately 40 minutes of runtime under normal mowing conditions. Real-world performance varies based on grass thickness, moisture level, and cutting height , with the second battery pack included, you can swap mid-mow and continue without waiting for a recharge.
Is the 13-inch deck wide enough, or will it take forever to mow my lawn?
The 13-inch deck width is best suited for small yards under roughly 1,500-2,000 square feet. It's narrower than the typical 18-inch walk-behind average, meaning you'll make more passes to cover the same ground , but on a compact urban or suburban lot, most users can finish in one or two battery charges.
Can I mulch or side-discharge clippings, or only bag them?
This model is configured for rear-bag discharge only, with a 1.24-bushel collection bag included. Mulching and side-discharge are not offered on this mower, so if you prefer to leave clippings on the lawn as natural fertilizer, this may not be the right fit.
How does the brushless motor compare to a regular brushed motor lawn mower?
Brushless motor technology eliminates the physical brushes that wear down in traditional motors, resulting in less heat, less friction, and longer motor life overall. In practical terms, the brushless motor offers more consistent power from a full battery down to a nearly depleted one, and the motor itself is less likely to require replacement over the life of the mower.
How compact is storage with the foldable handle , will it fit in a small apartment closet?
With the handle folded down, the mower's footprint drops dramatically , the lightweight 33.1 lb build and folding handle make it practical to store vertically against a wall, in a narrow closet, or in the back of a car for transport. It's one of the more storage-friendly designs in its category, with only about 27% of walk-behind mowers offering a comparable foldable handle.
Bottom Line
The MightyMow cordless electric mower is a well-matched tool for small-yard homeowners who prioritize convenience, low maintenance, and compact storage over raw cutting capacity. The brushless motor, dual battery packs, and foldable handle make it a genuinely practical package for urban lots and tight spaces , though buyers with larger lawns, hilly terrain, or a preference for mulching will want to look at a broader deck or self-propelled alternative.
Best for small flat yards under 1/8 acre where zero-emission, low-noise, and easy-storage mowing is the priority.
Consider alternatives if you have a yard larger than 1/8 acre, need a self-propelled drive for slopes, or want mulching capability.
