Key takeaways
- Cordless Convenience: Operating on dual batteries, the MZK lets you weave around tight corners, garden beds, and patio furniture without ever worrying about tripping over or slicing through an extension cord.
- Brushless Motor Efficiency: The inclusion of a brushless motor means longer runtimes, less friction, and extended overall lifespan for the tool compared to traditional brushed motors.
- Dedicated Grass Collection: It comes equipped with a proper grass bag, making clean-up effortless for small yards where leaving clippings behind is not an option.
What's inside
When you are staring down at a postage-stamp lawn or a awkwardly shaped courtyard, dragging out a heavy, petrol-guzzling mower feels completely absurd. Over the past few weeks, I have spent countless hours pushing micro-mowers across cramped turf strips, dealing with stubborn perimeter weeds, and dodging garden gnomes to see how these compact mowing solutions truly perform. Small yards present their own unique geometric challenges, where maneuverability and storage space matter far more than raw horsepower or massive fuel tanks.
That brings us to a showdown between two distinct approaches to compact lawn care: the MZK 20V 13-Inch Electric Lawn Mower and the BLACK+DECKER Electric Lawn Mower, Weed Eater and Edger 3-in-1 Combo (BESTA512CM). One leans heavily into cordless, modern freedom, while the other offers a multi-tool corded setup that tries to solve your entire yard maintenance routine in one budget-friendly package. Choosing between them in 2026 depends entirely on whether you despise extension cords more than you despise dealing with rechargeable battery packs.

Quick Verdict
Choose the MZK 20V 13-Inch Electric Lawn Mower if you want complete cordless freedom and a dedicated, highly maneuverable push mower designed specifically for tiny yards and tight spaces. Choose the BLACK+DECKER 3-in-1 Combo if you are operating on a strict budget and need an all-in-one corded tool that can function as a mower, weed eater, and edger.

Real-World Use: Which One Fits You
The Fenced Townhouse Courtyard
If your yard is completely enclosed by brick walls and has narrow pathways where a cord would constantly snag on fence posts, the MZK 20V 13-Inch is the undisputed winner. Its cordless design and compact red chassis let you pivot smoothly around corners and store it easily inside a hallway closet.
The Tight Sidewalk Strip
If you live on a property featuring a narrow strip of grass running right alongside a concrete driveway or pavement edge, the BLACK+DECKER shines. The ability to quickly convert the unit into an edger means you can clean up overgrown sidewalk borders right after mowing without swapping tools.
The Budget-Conscious Starter Home
If you just bought your first home and your garage tool budget is stretched paper-thin, the BLACK+DECKER 3-in-1 combo gives you a mower, trimmer, and edger all for a remarkably low price, provided you already own an extension cord.
Price and Value
The MZK comes in at $119.98, while the BLACK+DECKER is priced at $65.00, creating a direct price difference of $54.98. Whether that extra investment is justified depends entirely on how much you value your patience. Paying more for the MZK buys you the freedom of a dual-battery cordless system and a brushless motor tailored exclusively for nimble mowing. Meanwhile, the BLACK+DECKER packs immense monetary value by bundling a weed eater and edger into the package, though you pay for that discount in mobility via its corded requirement.
Final Recommendation
The MZK 20V 13-Inch Electric Lawn Mower is our overall top pick for small urban yards because its cordless, brushless design makes quick weekly maintenance an absolute breeze. However, the BLACK+DECKER wins the day if you are operating on a strict budget and desperately need a multi-tool setup that can edge, trim, and mow a tiny patch of turf while tethered to an outlet.
FAQ
Can the MZK mower handle tall, overgrown grass?
The MZK is built specifically for regular maintenance on small lawns and tight spaces rather than clearing out overgrown jungles. If you let your grass grow knee-high, a compact 13-inch cordless mower will struggle and drain the dual batteries much faster.
Is it difficult to switch the BLACK+DECKER between mowing, weed eating, and edging?
The system is engineered for quick transitions, allowing you to swap configurations with minimal effort using intuitive locking mechanisms. It is designed to let you finish mowing the main lawn and immediately tackle property borders without hassle.
Do I need to purchase extra batteries for the MZK?
The unit ships with dual batteries included in the package to power its 20V system, so you can unbox it and get straight to work. For extremely small yards, the included capacity should easily get through a standard mowing session.
How loud are these electric mowers compared to gas alternatives?
Both electric models operate at a significantly lower decibel level than traditional petrol mowers, meaning you can mow early on a weekend morning without disturbing your neighbors. You will hear the electric motor hum, but it requires zero ear protection.
