Living with a small patch of green can feel like being stuck between a rock and a hard place. I remember my first townhouse, with its charming but diminutive 15×20 foot backyard. It was my little slice of outdoor heaven, but maintaining it was a constant puzzle. A full-sized gas mower felt like bringing a cannon to a knife fight—it was bulky, loud, expensive, and took up nearly half of my tiny storage shed. For a while, I relied solely on a string trimmer, which left the lawn looking choppy and uneven. The alternative, hiring a lawn service for a job that literally takes five minutes, felt financially absurd. This is the precise dilemma so many of us face: the need for a proper lawn tool that respects our limited space, budget, and the scale of the job. It’s a search for a solution that is powerful enough to do the job right, but compact and versatile enough to justify its existence in a small home.

What to Consider Before Buying a Walk-Behind Lawn Mower
A Walk-Behind Lawn Mower is more than just an item; it’s a key solution for maintaining the health and aesthetic of your property. Whether you’re dealing with a sprawling suburban lawn or a tiny urban postage stamp, the right mower can transform a weekly chore from a dreaded task into a satisfying ritual. These machines offer direct control and maneuverability that larger riding mowers can’t match, allowing for precise cuts around flower beds, trees, and other obstacles. The primary benefit is achieving a clean, uniform look for your lawn, which not only boosts curb appeal but also promotes healthier grass growth by ensuring each blade gets adequate sunlight and air.
The ideal customer for this type of product is someone with a small to medium-sized yard who values simplicity, storage space, and affordability. This includes homeowners in townhouses, condos with small yards, or houses on compact lots. If you’re tired of the noise, fumes, and maintenance of a gas engine and don’t have the acreage to justify a riding mower, a compact electric model is a perfect fit. Conversely, it might not be suitable for those who have very large properties (a quarter-acre or more), as managing an extension cord or relying on battery life can become impractical. For those with expansive, hilly, or rough terrain, a more powerful self-propelled gas mower or even a riding mower would be a more efficient, albeit more expensive, alternative.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Consider both the cutting width (deck size) and the overall storage footprint. A wider deck, like 21 inches, covers ground faster but is harder to maneuver in tight spaces. A smaller 12-inch deck, like the one on the model we’re reviewing, is perfect for intricate yards but requires more passes. Also, think about where you’ll store it; lightweight, collapsible models are a blessing for those without a large garage.
- Capacity/Performance: Power source is the biggest decision. Corded electric models offer unlimited runtime and consistent power but limit your range. Cordless battery models offer total freedom but are constrained by battery life and can be more expensive. Gas models provide the most power but come with noise, emissions, and regular maintenance. Look at motor power (Amps for corded, Volts for cordless) to gauge its ability to handle thick or tall grass.
- Materials & Durability: Mower decks are typically made of either steel or a hard composite plastic. Steel is heavier and more durable against rocks and impacts but can rust if not cared for. Plastic decks are rust-proof and much lighter, making the mower easier to push and carry, but they can be more susceptible to cracking under extreme stress.
- Ease of Use & Maintenance: Look for features that make your life easier. Push-button start is far simpler than a pull-cord. Single-lever height adjustment is more convenient than changing each wheel individually. For long-term care, electric models are virtually maintenance-free beyond cleaning, while gas mowers require oil changes, spark plug replacements, and fuel stabilizing.

First Impressions: A Featherweight Champion Unboxed
Upon receiving the BLACK+DECKER 3-in-1 Mower Trimmer Edger, the first thing that struck me was the sheer lack of weight in the box. At just under 10 pounds, I could easily carry it with one hand. Unboxing confirmed my suspicion: this isn’t your grandfather’s hefty steel-decked mower. The assembly process was, refreshingly, almost non-existent. As many users have gleefully reported, it’s a matter of snapping two main pieces together. I attached the auxiliary handle and the safety guard to the string trimmer, and that was it. No tools, no confusing diagrams, no frustration. The entire “build” took less than five minutes.
The core of the system is a 6.5-amp string trimmer, which feels robust and well-balanced on its own. The mower component is a simple, four-wheeled plastic deck that the trimmer clicks into with a foot pedal. The plastic construction feels light, but not flimsy. It’s a clever design that immediately makes sense for its target audience. It’s a tool designed for convenience and compact storage, a concept that many manufacturers of larger equipment seem to forget. This is a machine you can hang on a hook in a closet, not something that commands a permanent two-square-foot patch of your garage floor.
Key Benefits
- Incredibly lightweight and easy to maneuver at only 9.9 lbs
- True 3-in-1 versatility acts as a mower, trimmer, and edger
- Surprisingly powerful 6.5-amp motor tackles tall grass
- Compact design is perfect for small yards and limited storage space
Drawbacks
- Mower deck attachment can detach on uneven terrain
- Corded design requires careful management of an extension cord (not included)
Performance Deep Dive: Putting the 3-in-1 to the Test
A tool that promises to do three jobs often excels at none. I was skeptical that this lightweight, plastic combo could deliver a truly satisfying lawn care experience. Could a string trimmer on wheels really replace a dedicated mower? Over several weeks of testing on a small, challenging lawn with tight corners and uneven spots, the BLACK+DECKER 3-in-1 Mower Trimmer Edger revealed its unique character—a mix of surprising capability and understandable compromise.
The 3-in-1 Transformation: Seamless or Stuttering?
The genius of this machine lies in its modularity. Switching between functions is, for the most part, a simple, tool-free process. To mow, you place the trimmer into the wheeled mower deck and press down until it clicks securely. A foot pedal releases it just as easily. To switch from trimming to edging, a quick twist of the shaft rotates the cutting head 90 degrees. In practice, this works exactly as advertised and is a joy to use. I could mow the main patch of grass, pop the trimmer out to clean up around the fence posts, then rotate the head to create a sharp edge along the sidewalk, all within minutes.
However, the system’s biggest weakness, and a point frequently raised by other users, is the security of the trimmer-to-deck connection. One user lamented, “That tiny tab is supposed to hold that big ol thing in place?? Well, it does not.” I found this to be partially true. On a flat, smooth lawn, the connection is perfectly stable. But the moment I hit a bump, a tree root, or tried to make a sharp turn on a slight incline, the trimmer would occasionally pop out of the base. It’s not a deal-breaker, but it does force you to adopt a more gentle, deliberate mowing style. You can’t manhandle this mower; you have to guide it. After a little practice, I learned its limits and could avoid the issue, but it’s a design quirk worth noting.
Surprising Power: The 6.5-Amp Motor and POWERDRIVE in Action
Let’s be clear: this is a string trimmer-based mower. It doesn’t have a steel blade. So, how does it cut? The answer is: surprisingly well. The 6.5-amp motor, combined with BLACK+DECKER’s POWERDRIVE Transmission, provides a remarkable amount of torque. The system spins the trimmer line at 8000 RPM, which is more than enough to slice through standard lawn grass with ease, leaving a clean, even finish. The real test, however, was a patch of lawn I had let go for two weeks, where the grass was pushing 8-10 inches tall and thick with weeds.
I was genuinely impressed. Echoing the experience of one user who tackled a “small jungle,” the mower chewed through the overgrown mess without stalling. It required a slower pace and sometimes a second pass, but it never gave up. This is not a brush cutter, and it won’t handle thick, woody stems, but for dense grass, it’s a little workhorse. The 12-inch cutting path is narrow, meaning more passes are needed, but its small size allows it to get into tight spots a larger mower could never reach. The cutting height is fixed at 1.6 inches, which is on the shorter side but provided a neat, tidy look for my lawn type. For anyone doubting if a string can truly mow, the powerful performance of this tool is a convincing argument. You can see this impressive little machine in action and check its price here.
Living the Corded Life: Convenience and Constraints
The power source is the single biggest factor that defines the experience with this tool. Being corded, the BLACK+DECKER 3-in-1 Mower Trimmer Edger provides two key benefits: it’s incredibly lightweight without a heavy battery, and it has unlimited runtime. I never had to pause my work to wait for a battery to charge. The downside, of course, is managing the extension cord. This is an unavoidable reality of any corded lawn tool.
You quickly develop a strategy, working your way away from the outlet in a pattern that keeps the cord out of your cutting path. BLACK+DECKER includes a helpful cord retention system on the handle that prevents accidental disconnection, which I found worked perfectly. A crucial piece of advice, echoed by nearly every seasoned owner, is to invest in a quality 50-foot or 100-foot extension cord (a 2-prong cord is required). One user noted a very specific design flaw where the recessed plug housing was too narrow for their generic cord, forcing them to modify the tool’s handle. I tested this with several cords and found that while most fit, bulkier, heavy-duty plug ends could indeed be problematic. It’s a small but frustrating detail that could be easily improved.
Ergonomics and Usability: A Closer Look at the Details
Beyond the core functions, the user experience is solid. The tool is highly adjustable to fit different user heights. One meticulous user measured the handle height from 22.5 inches at its lowest to 31.5 inches at its highest, confirming our findings that it offers a comfortable operating position for most people. At under 10 pounds, there is virtually no fatigue from pushing it in mower mode.
A standout feature is the Automatic Feed Spool (AFS). For anyone who has ever wrestled with an old-school bump-feed trimmer, the AFS is a revelation. It automatically advances the line as needed without any intervention from the user. Throughout my testing, it worked flawlessly, providing a consistent cutting width without interruption. As with any string trimmer, the line is a consumable. One user reported that the starter spool ran out in under 15 minutes during a heavy cleanup job. My experience was better, lasting for a few full-yard sessions, but the lesson is the same: buy a multi-pack of replacement spools (model AF-100) when you purchase the tool. It will save you a trip later.
What Other Users Are Saying
After extensively testing the machine, I delved into hundreds of user experiences to see how my findings aligned. The consensus is overwhelmingly positive, provided the owner has the right expectations and the right type of yard. The praise is most effusive from those in similar situations to my own: condo and townhouse dwellers with minimal storage and small lawns. One user perfectly captured the sentiment, calling it the “Best purchase EVER” because it solved the problem of storage and allowed them to easily carry it through their living room without a mess. Another celebrated its power, showing a video of it cutting through very high grass “like it was nothing.”
The criticisms are just as consistent and mirror the limitations I discovered. The most common complaint is the mower deck’s tendency to pop off on uneven ground. While some users found it frustrating, most, like me, learned to work around it by being more gentle. The second major point of friction is the cord. While users love the consistent power, the hassle of cord management is a frequent mention, as is the fact that an extension cord is a required separate purchase. These critiques are fair and serve as an important qualifier: this is a fantastic tool, but it’s not without its quirks.
How Does the BLACK+DECKER 3-in-1 Mower Trimmer Edger Compare to the Alternatives?
The BLACK+DECKER 3-in-1 Mower Trimmer Edger occupies a unique space in the market, but for those considering other options, especially cordless ones, here’s how it stacks up against some popular alternatives.
1. Greenworks 40V 16″ Cordless Push Mower 4.0Ah Battery
- Effortless Power for ½ Acre Yards- Experience gas-like performance without the hassle—35 minutes of continuous runtime from a single 4.0Ah battery (full charge in 2 hours). Perfect for small to...
- Ultra-Lightweight Design (35% Lighter)- 16" cutting deck with ergonomic handles and push-button start makes maneuvering effortless—ideal for users prioritizing comfort and ease of storage.
- Smart Cut Adjustment System- Single-lever 5-position height control (1.25"-3.375") adapts to any grass type. 2-in-1 mulching/rear-bagging system maximizes clippings management.
The Greenworks 40V mower is a step up into the world of dedicated cordless mowing. Its main advantage is freedom from the cord, powered by a robust 4.0Ah battery. With a wider 16-inch cutting deck, it will cover a small-to-medium lawn faster than the BLACK+DECKER model. However, it is a dedicated mower only—it does not include trimming or edging functions. It’s also significantly heavier and bulkier, making storage more of a consideration. This is the better choice for someone with a slightly larger yard who prioritizes the convenience of cordless power and already owns or plans to buy separate tools for trimming and edging.
2. EGO Power+ LM2112 Cordless Push Electric Lawn Mower
- Delivers up to 6.0 ft-lbs of cutting torque for performance that exceeds gas lawn mowers
- Up to 35 minutes run time on a single charge with the 56V 4.0Ah ARC Lithium battery
- High-efficiency brushless motor delivers long runtimes, low vibration, and lifelong durability
The EGO Power+ represents the premium end of the cordless electric mower spectrum. Its 56V platform delivers power that rivals gas mowers, and its build quality is exceptional. With a large 21-inch deck, it’s designed for serious yard work on lawns up to a half-acre. While its performance is in a different league, so is its price and size. This alternative is for the homeowner with a substantial lawn and budget who wants the absolute best in cordless performance and is not constrained by storage space. It is a completely different class of machine compared to the compact and budget-friendly BLACK+DECKER.
3. LawnMaster CLM2413A 13-Inch Cordless Lawn Mower
- [12.4-INCH CUTTING WIDTH] With 13-inch high impact rust resistant deck
- [POWERFUL ENGINE] Powered by a 24V MAX* li-ion battery(ASIN:B093FJDKFM) provides a speed of 3700 RPM
- [5 CUTTING POSITONS] Effortlessly change the height of cuts between 1-inch to 2.55-inch using the one-touch lever
The LawnMaster is perhaps the closest cordless competitor in spirit. It offers a compact 13-inch cutting deck and is also very lightweight, focusing on ease of use for smaller yards. Like the Greenworks, it frees you from the cord, which is a major plus. However, its 24V battery system provides less power and runtime than the 40V or 56V systems. It’s a good middle-ground option for someone who is set on a cordless mower for a small yard but doesn’t want to pay the premium for a high-power system. You still lose the 3-in-1 versatility that makes the BLACK+DECKER so unique.
The Final Verdict: A Niche Product That Hits a Home Run
After weeks of mowing, trimming, and edging, my conclusion is clear: the BLACK+DECKER 3-in-1 Mower Trimmer Edger is a brilliantly designed solution for a very specific problem. It is not trying to be a heavy-duty mower for a quarter-acre lot, and it shouldn’t be judged as one. This is the ultimate lawn care tool for the space-constrained homeowner. For anyone living in a townhouse, a condo, or a home with a small, relatively flat yard, this machine is a game-changer.
Its incredible lightweight design, near-zero assembly, and compact storage profile are its greatest strengths. The 3-in-1 versatility isn’t just a gimmick; it genuinely works, allowing you to perfect your entire lawn with a single, easy-to-handle tool. While the finicky mower deck connection and the hassle of a cord are notable drawbacks, they are manageable compromises for the immense convenience it offers. If you have the right yard for it, this isn’t just a good tool; it’s arguably the perfect tool.
