For years, my weekend lawn care ritual was a familiar assault on the senses. It started with the frustrating pull-cord dance—a game of chance that often left my shoulder sore and my patience thin. Then came the deafening roar of the gas engine, a neighborhood-wide announcement that I was, once again, wrestling with my yard. The smell of gasoline and exhaust fumes would hang in the air long after the job was done. It was a chore I dreaded, a noisy, messy, and frankly, archaic process. I knew there had to be a better way to achieve a pristine lawn without the weekly headache. The dream was simple: a powerful, reliable mower that started with a button, ran quietly, and didn’t require me to store flammable liquids in my garage. This search for a modern solution led us directly to the burgeoning world of cordless electric mowers, a category where the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower promised to deliver on every front.

What to Consider Before Buying a Cordless Electric Lawn Mower
A walk-behind lawn mower is more than just an item; it’s a key solution for maintaining the health and beauty of your property. In the case of cordless electric models, it represents a significant leap forward in convenience and environmental responsibility. These machines solve the core problems of their gas-powered predecessors: excessive noise, polluting emissions, and constant, messy maintenance involving oil, gas, and spark plugs. The main benefits are profound—they offer a quieter, cleaner, and simpler mowing experience, allowing you to care for your lawn at any time of day without disturbing your family or neighbors. They start instantly, are significantly lighter, and often require little more than keeping the blades sharp and the batteries charged.
The ideal customer for this type of product is someone facing the typical challenges of a small to medium-sized suburban yard, roughly up to half an acre. This includes homeowners who value a peaceful neighborhood environment, are eco-conscious, or are simply tired of the mechanical upkeep of gas engines. It’s a perfect fit for those who want a grab-and-go solution. However, a cordless electric push mower might not be suitable for those who have exceptionally large properties (over an acre), or who regularly tackle extremely dense, overgrown, or rugged terrain. In those scenarios, the power and wider cutting decks of high-end gas mowers, particularly self-propelled models, might still be necessary. For a look at what the gas-powered world has to offer, we’ve compiled a comprehensive guide.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The cutting width, or deck size, is paramount. The 17.9-inch deck on the MightyMow is a fantastic middle-ground, offering great maneuverability for yards with trees, flower beds, and other obstacles. A larger deck cuts more grass per pass, saving time on wide-open lawns, but can be cumbersome in tight spaces. Also, consider storage; this mower’s lighter frame and adjustable handle make it easier to store in a crowded garage or shed.
- Capacity/Performance: In the cordless world, performance is measured by the battery system and motor. A brushless motor, like the one in this MightyMow, is a must-have; it’s more efficient, quieter, and has a longer lifespan than older brushed motors. Pay close attention to the battery voltage (V) and amp-hours (Ah)—higher numbers generally mean more power and longer runtime. A dual-battery system provides extended capacity to finish larger jobs in one go.
- Materials & Durability: Mower decks are typically made of either plastic (or a composite polymer) or steel. The MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower features a durable plastic deck, which has the significant advantages of being lightweight and completely rust-proof. Steel decks are heavier and can be more resilient to major impacts, but they are also susceptible to rust if scratched or left in wet conditions.
- Ease of Use & Maintenance: Modern features can make all the difference. Look for a single-lever height adjustment system, which allows you to change the cutting height of all four wheels simultaneously with one hand. An adjustable handle caters to users of different heights, improving ergonomics. The biggest ease-of-use factor is the near-zero maintenance: no oil changes, no gas runs, no winterizing the engine.
Keeping these factors in mind, the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower stands out in several areas. You can explore its detailed specifications and features here.
While the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower is an excellent choice for the modern homeowner, it’s always wise to see how it stacks up against the competition.

First Impressions: Unboxing and Assembling the MightyMow
Our experience with the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower began the moment the box arrived. Pulling it out, the first thing we noticed was its weight. At just 18 kilograms (around 40 pounds), it felt substantially lighter than any gas mower we’ve handled. This was a promising start, suggesting it would be easy to push and maneuver. Assembly, as one user correctly noted, was practically non-existent. The main unit was fully intact; all we had to do was unfold the three-position adjustable handle and tighten the included bolts. The entire process took less than five minutes, with no tools required other than our hands. The two 4.0Ah batteries clicked satisfyingly into the dual charger, and we were ready to go. Aesthetically, the mower has a “Modern” black design that looks sleek and capable. The plastic deck feels robust and durable, not at all flimsy, and the single lever for height adjustment moved with a firm, confident click through its six positions. It immediately gave the impression of a well-designed tool built for convenience.
Key Benefits
- Powerful and quiet high-efficiency brushless motor
- Excellent runtime of up to 40 minutes with included dual batteries
- Extremely lightweight and easy to maneuver
- Convenient single-lever 6-position height adjustment
- Virtually zero assembly required out of the box
Potential Drawbacks
- Primarily plastic construction may not be as durable as steel for heavy-duty use
- Not self-propelled, which could be a factor on steep inclines
A Deep Dive into the MightyMow’s On-the-Ground Performance
A mower’s true worth is only revealed on the lawn. Specifications and first impressions are one thing, but performance under real-world conditions is what truly matters. We put the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower through a series of tests on a typical quarter-acre suburban lot with varied conditions—from thin, sunny patches to thicker, lusher grass in the shade. The results were, to put it simply, deeply impressive and aligned perfectly with the enthusiastic feedback from other users.
The Heart of the Machine: Brushless Motor and Cutting Power
Any skepticism we had about a battery-powered mower tackling thick grass vanished on the first pass. The high-efficiency brushless motor, spinning at up to 4200 RPM, is the star of the show. Unlike the sputtering start of a gas engine, the MightyMow springs to life instantly and quietly with the push of a button and the pull of a lever. The sound is a low, powerful hum, more akin to a high-powered fan than a traditional lawn mower. We could easily hold a conversation while it was running, a feat unimaginable with its gasoline-guzzling cousins. This quiet operation is a game-changer, allowing for early morning or evening mowing without becoming a neighborhood nuisance.
But quiet doesn’t mean weak. We deliberately steered it towards a patch of lawn that was slightly longer and thicker than the rest. The motor’s torque delivery was smooth and consistent; it powered through without bogging down or showing any signs of struggle. The 17.9-inch steel blade left a clean, even cut in its wake, creating that satisfying, well-manicured look. This confirmed what several users reported: this machine “powers right through the grass” and “doesn’t sacrifice any power.” It efficiently lifted the clippings and sent them into the 40-liter collection bag, which filled up surprisingly fast, a testament to its effective cutting and collection system. The cut quality was consistently neat and professional across the entire lawn.
Cordless Freedom: The 2x20V Battery System in Action
The single biggest point of hesitation for those considering a switch to electric is “battery anxiety.” Will it have enough juice to finish the job? The MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower directly addresses this concern with its intelligent dual-battery system. The kit includes two 20V, 4.0Ah batteries that work in tandem to deliver 40V of power. The company’s claim of a 40-minute runtime proved to be spot-on in our testing. We mowed our entire quarter-acre test lawn, which took about 35 minutes of continuous operation, and the battery indicator still showed a small amount of charge remaining. This is more than enough capacity for the vast majority of suburban lawns.
The included dual-port charger is another fantastic convenience. It replenishes both batteries simultaneously, ensuring you’re ready for the next mow with minimal downtime. The freedom this system provides is liberating. There are no cords to get tangled or accidentally run over, and no last-minute trips to the gas station. You simply pop in the charged batteries and go. For homeowners with lawns up to a third of an acre, this battery platform is a perfect match, providing the power and runtime needed to get the job done reliably on a single charge. If you’re ready to experience this level of convenience, you can find the complete mower package with batteries and charger included.
Ergonomics and User-Friendliness by Design
Beyond its motor and batteries, this mower excels in pure user experience. Every design choice seems geared toward reducing effort and fatigue. Weighing only 18kg, it feels incredibly nimble. Pushing it across the lawn requires minimal effort, and navigating around garden beds, trees, and walkways is effortless. This lightweight design makes lawn care less of a physical workout and more of a pleasant walk.
The single-lever height adjustment is a feature we can’t overstate the convenience of. Instead of fumbling with four individual levers on each wheel, one simple, sturdy handle allows you to cycle through the six cutting heights, from a low 1 inch to a higher 3 inches. This makes it incredibly easy to adapt to different parts of your lawn on the fly. The three-level adjustable handlebar is another thoughtful touch, ensuring users of any height can find a comfortable and ergonomically correct pushing posture. When the job is done, the handle folds down completely, allowing the mower to be stored vertically against a wall or tucked away on a shelf, saving precious garage space. From its five-minute setup to its easy storage, the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower is a masterclass in user-centric design.
What Other Users Are Saying
Our positive experience is strongly echoed across a wave of user feedback. The consensus is overwhelmingly enthusiastic, particularly from those making the switch from gas mowers for the first time. One user called it a “game-changer for a medium-sized yard,” confirming our findings about the 40-minute runtime being “spot-on” for their quarter-acre lawn. They, too, praised the brushless motor for being both quiet and powerful, easily handling thicker grass.
Another common theme is the sheer simplicity and ease of use. Sentiments like, “It’s very light, easy to push, quiet, and powers right through the grass,” are frequent. Many were initially skeptical of battery power but found that “this machine does not disappoint.” The near-instant assembly was also a highlight, with one person noting it “came pretty much assembled.” Overall, the user community validates our assessment: the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower delivers on its promises of power, convenience, and a superior mowing experience, leaving lawns looking “neatly and cleanly” trimmed.
How Does the MightyMow Compare to the Alternatives?
The MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower shines in its category, but different lawns have different needs. Here’s how it stacks up against some other popular options.
1. PowerSmart 21-Inch 144cc Push Mower
- Gas Powered Engine: A 144cc 4-cycle OHV engine equipped with recoil starter and auto choke for easy start, delivers strong power.
- 2-in-1 Steel Deck: All-steel deck built to last, combine mulching and bagging capabilities in 1.
- 21" Cutting Blade: The heavy-duty blade delivers better cutting effect, allowing you to mow more in less time.
This is a classic gas-powered push mower. Its primary advantages over the MightyMow are its wider 21-inch cutting deck and the raw, untethered power of its 144cc gas engine. It’s a better choice for someone with a larger yard (half an acre or more) who needs to cut a lot of grass quickly and may encounter very tough, dense patches. However, this power comes with the significant drawbacks of loud noise, exhaust fumes, regular maintenance (oil, gas, spark plugs), and a much heavier frame, making it more difficult to maneuver and store.
2. Great States 18-Inch 5-Blade Push Reel Mower
- The Great States motor-less lawnmower with an adjustable cutting height of 0.5"-2.75" for a clean, even cut
- 18" cutting width 5-blade manual push mower with 5-blade ball-bearings, and 10" composite wheels
- Push mower blades are made of high-quality alloy steel that stay sharp longer
The Great States reel mower represents the opposite end of the spectrum. It’s a completely manual, human-powered machine. Its benefits are absolute silence, zero emissions, and virtually no maintenance besides blade sharpening. It’s an excellent choice for very small, flat, and well-maintained lawns where the user enjoys the physical activity. However, it is completely ineffective on tall grass, weeds, or uneven terrain, all areas where the powered blade of the MightyMow excels with ease. It’s a specialist tool for a specific type of lawn and owner.
3. LawnMaster GVB1316 16-Inch Electric Dethatcher
- 2-IN-1 FUNCTION: Dethatch your lawn to remove thick thatch and allow your lawn to get more nutrients and sunlight. Scarify to cut grooves that improve water and air movement through the soil
- POWERFUL PERFORMANCE: The 13 Amp motor, gets up to 3700RPM. This gives adequate power to dethatch or scarify some of the toughest lawns
- 16” WIDE PATH: Equipped with 16“ dethatcher/scarifier attachments to tackle the job faster
It’s important to note that this is not a lawn mower. The LawnMaster is a dethatcher and scarifier, a specialized lawn health tool. Its purpose is to remove the layer of dead grass and debris (thatch) from the soil’s surface, which improves air, water, and nutrient flow to the grass roots. While the MightyMow cuts the grass, the LawnMaster revitalizes the lawn itself. This isn’t an alternative but a potential companion tool. A dedicated homeowner might use the LawnMaster once or twice a year and the MightyMow every week.
The Final Verdict: Is the MightyMow Right for You?
After extensive testing and analysis, our conclusion is clear: the MightyMow 2x20V 17.9 inch Cordless Electric Lawn Mower is a phenomenal piece of equipment that delivers a truly modern lawn care experience. It successfully eliminates all the traditional pain points of mowing—the noise, the fumes, the maintenance—without compromising on cutting power or performance for its target lawn size. Its combination of a potent brushless motor, reliable dual-battery system, lightweight maneuverability, and dead-simple operation makes it an outstanding choice.
We highly recommend it for any homeowner with a small to medium-sized lawn who is ready to upgrade from a cumbersome gas mower or an underpowered older electric model. While the plastic deck may give pause to those used to heavy steel, its durability proved more than adequate for residential use, and the benefits of its light weight are felt with every push. It’s a machine that makes you actually look forward to mowing the lawn.
