40V Cordless Lawn Mower
BLACK+DECKER Electric Push Lawn
Choosing the right lawn mower can feel like navigating a maze of options—especially when you’re deciding between cordless freedom and reliable corded power. On one side, we have the 40V Cordless Lawn Mower, a battery-powered workhorse designed for small to medium yards that leverages your existing Dewalt 20V MAX batteries. On the other, the BLACK+DECKER Electric Push Lawn offers a no-nonsense, plug-in solution with a beefy 13-amp motor and a generous 20-inch cutting deck. Both promise clean cuts and user-friendly operation, but they cater to very different needs and lifestyles.
This comparison matters because your lawn care routine should match your yard size, physical ability, storage space, and how much hassle you’re willing to tolerate—like untangling cords or hunting for extra batteries. Whether you’re a weekend warrior with a compact suburban plot or someone managing a larger lawn without gas fumes or oil changes, picking the right tool saves time, effort, and frustration. By the end of this article, you’ll know exactly which mower aligns with your priorities, from runtime and cutting width to noise levels and ease of storage.
In-Depth Look: 40V Cordless Lawn Mower
The 40V Cordless Lawn Mower is a clever piece of engineering aimed at homeowners who already own Dewalt 20V MAX tools. Instead of buying a proprietary battery system, this mower lets you double up two of your existing 20V batteries to deliver 40 volts of clean, consistent power—no gas, no cords, no emissions. That’s a huge win if you’ve invested in the Dewalt ecosystem for drills, saws, or trimmers.
One standout feature is its 14-inch cutting deck, which is wider than many compact cordless models (often stuck at 13 inches). This means fewer passes over your lawn, saving time and effort. The six-position height adjustment (from just under 1 inch up to 3 inches) gives you fine control over grass length, whether you’re maintaining a tidy spring lawn or tackling summer overgrowth. Plus, the upgraded copper motor and manganese steel blade combo delivers surprisingly strong cutting performance—even through thick or damp grass—without the roar of a gas engine.
At only 22 pounds, this mower is featherlight compared to most electric models. That makes it ideal for seniors, people with mobility concerns, or anyone tired of wrestling with heavy equipment. The 35L grass bag reduces how often you need to stop and empty, and the foldable handle means it stows flat in tight spaces—perfect for garages or sheds with limited room. Safety is also well considered: a double-switch system prevents accidental startups, and tool-free assembly gets you mowing in minutes.
But it’s not perfect. The biggest caveat? Battery and charger not included! If you don’t already own two compatible Dewalt 20V MAX batteries (and preferably 4.0Ah or higher), you’ll need to buy them separately—which can add $100–$200 to your total cost. Also, the battery compartment is snug; don’t try cramming in larger capacity packs unless they’re officially supported.
Customer feedback has been overwhelmingly positive. One user raved, “If you have a small area to mow or need a mower to cut around your house, this is the one! I’ve been impressed with the quality and toughness… It mows through tall grass and the battery lasts a good while.” Another added, “Super lightweight making it so easy to use—works great. Definitely 5 stars.” A third praised its convenience: “Much more convenient than corded mowers. Great buy for the price.”
This mower shines brightest for small to medium yards (under ¼ acre), urban gardeners, eco-conscious homeowners, or anyone already deep in the Dewalt battery universe. It’s also excellent for quiet neighborhoods where early-morning mowing shouldn’t wake the block.
In-Depth Look: BLACK+DECKER Electric Push Lawn
The BLACK+DECKER Electric Push Lawn is a classic workhorse—simple, powerful, and built for reliability. With a robust 13-amp motor, it delivers ample torque to slice through thick grass, weeds, or overgrowth without breaking a sweat. Unlike battery-powered models, it offers unlimited runtime as long as you have access to an outdoor outlet—no worrying about dying batteries mid-mow.
Its 20-inch cutting deck is significantly wider than the 40V Cordless Lawn Mower’s 14-inch path, meaning you’ll cover more ground with each pass. That makes it a better fit for larger yards (up to ½ acre) or anyone who values efficiency over portability. The single-lever height adjustment offers six settings from 1.5 to 4 inches—ideal for seasonal lawn care or adapting to different grass types.
BLACK+DECKER includes thoughtful ergonomic touches: a foam-padded grip reduces hand fatigue, and the lift handle makes transporting the mower easier despite its weight (~50 lbs). The winged blade design optimizes grass collection, and like the cordless model, it folds flat for compact storage—though it takes up more space due to its size.
However, the corded design is both its strength and weakness. You’ll need to manage an extension cord while mowing, which can be cumbersome around trees, flower beds, or garden borders. And if your yard doesn’t have nearby outlets, you may need a long, heavy-duty outdoor extension cord—adding cost and tripping hazards.
While there are no customer reviews listed for this specific model, BLACK+DECKER’s reputation for durable, no-frills electric mowers is well established. Users typically praise their reliability, consistent power, and low maintenance compared to gas mowers.
This mower is best suited for homeowners with medium to large flat yards, those who prioritize raw cutting power over portability, and anyone who doesn’t mind managing a cord. It’s also a great choice if you want a “set it and forget it” mower that won’t run out of juice halfway through.
Head-to-Head Comparison
Performance & Power
The BLACK+DECKER Electric Push Lawn wins on pure muscle with its 13-amp motor, which outperforms most 40V cordless mowers in dense or wet grass. However, the 40V Cordless Lawn Mower holds its own thanks to its high-torque copper motor and sharp steel blade—delivering gas-like performance without the fumes.
Runtime & Convenience
Here’s the trade-off: unlimited runtime vs. cordless freedom. If you have outlet access and a large yard, the BLACK+DECKER’s continuous power is unbeatable. But if you value mobility, hate cords, or mow in areas far from outlets, the 40V Cordless Lawn Mower’s ~45–60 minute runtime (with two 4.0Ah batteries) is plenty for small to medium lawns.
Ease of Use & Portability
At 22 lbs versus 50 lbs, the 40V Cordless Lawn Mower is dramatically easier to push, maneuver, and store. Its lightweight design makes it ideal for seniors or those with physical limitations. The BLACK+DECKER, while sturdy, demands more effort—especially on slopes or when turning tightly.
Cutting Width & Efficiency
The BLACK+DECKER’s 20-inch deck covers 43% more area per pass than the 14-inch cordless model. For large yards, that translates to significant time savings. But for small, intricate landscapes with lots of landscaping features, the narrower cordless mower offers better precision.
Noise & Environmental Impact
The 40V Cordless Lawn Mower operates nearly silently—perfect for early mornings or noise-sensitive areas. The BLACK+DECKER hums noticeably louder, though still far quieter than gas mowers. Both are emission-free, but the cordless model wins on stealth.
Frequently Asked Questions
Q: Can I use any Dewalt 20V battery with the 40V Cordless Lawn Mower?
A: Only two 20V MAX batteries are supported, and the compartment fits a maximum of 4.0Ah packs. Larger capacities may not fit. Always check compatibility before purchasing. Check compatibility details on Amazon.
Q: Do I need an extension cord for the BLACK+DECKER Electric Push Lawn?
A: Yes, unless your outlet is very close to your lawn. Use a heavy-duty outdoor-rated extension cord (12-gauge recommended) to ensure safe, full power delivery. See product specs for cord requirements.
Q: Which mower is better for hills or uneven terrain?
A: The lighter 40V Cordless Lawn Mower (22 lbs) is easier to control on slopes. For tips on mowing safely on hills, see our guide on lawn care on inclines.
Q: Can either mower mulch or bag grass?
A: Both models support bagging, but neither includes a mulching plug. If mulching is essential, consider a dedicated mulching mower like those discussed in our mulching vs. vacuum comparison.
Q: Is the 40V Cordless Lawn Mower worth it if I don’t own Dewalt tools?
A: Only if you plan to invest in the Dewalt ecosystem. Otherwise, the added cost of two batteries may outweigh the benefits. Explore alternatives in our best hand lawn mowers guide for budget-friendly options.
Final Verdict: Which One Should You Choose?
Your ideal mower depends entirely on your yard and lifestyle. If you have a small to medium yard, already own Dewalt 20V MAX batteries, and value lightweight, quiet, cord-free operation, the 40V Cordless Lawn Mower is a smart, eco-friendly upgrade that integrates seamlessly into your existing tool collection.
On the other hand, if you manage a larger lawn, prioritize cutting power and runtime, and don’t mind managing an extension cord, the BLACK+DECKER Electric Push Lawn delivers unmatched efficiency and reliability at a competitive price.
Both are excellent in their own right—but only one will fit your grass-cutting life like a glove. Ready to make the cut? Grab the 40V Cordless Lawn Mower here or choose the BLACK+DECKER Electric Push Lawn today—and get back to enjoying your yard, not just maintaining it.
