I remember the Sunday ritual all too well: the trip to the gas station to fill up the red can, the careful mixing of oil, the frustrating yanking of a pull-cord that seemed to fight back with every pull. Then came the deafening roar of the engine, the smell of fumes, and the separate dance of dragging out the trimmer and blower. My garage was a cluttered mess of different tools, fuel types, and extension cords. It turned a simple task—maintaining my lawn—into a multi-stage, noisy, and frankly, grimy ordeal. This frustrating cycle is a common pain point for homeowners who just want a clean, quiet, and efficient way to care for their yard without the hassle. The dream is a single, integrated system that simplifies the entire process, from the first cut to the final cleanup.

What to Consider Before Going All-In on an Electric Mower Kit
A walk-behind lawn mower kit is more than just a collection of items; it’s a key solution for reclaiming your weekend and simplifying your entire lawn care routine. The primary benefit of an integrated battery-powered system is the shared power source. One set of batteries runs everything, eliminating the need for gasoline, oil changes, spark plug replacements, and tangled cords. This shift not only reduces maintenance and running costs but also significantly lowers noise pollution and eliminates emissions, making for a more pleasant experience for both you and your neighbors. It represents a streamlined, eco-friendly approach to achieving a beautiful lawn.
The ideal customer for this type of product is a homeowner with a small to medium-sized yard (typically up to half an acre) who values convenience, low maintenance, and a quieter operation. It’s perfect for someone who is tired of the complexities of gas engines or the limitations of corded tools and wants a powerful, all-in-one solution. However, it might not be suitable for those with very large properties (over an acre) where battery runtime could become a significant issue, or for commercial landscapers who require day-long, non-stop performance. For those users, a high-horsepower gas mower or a professional-grade battery system with a large arsenal of swappable batteries might be a more practical choice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: A major, often-overlooked advantage of many modern battery mowers is their storage footprint. Gas mowers cannot be stored vertically due to potential fuel and oil leaks. Look for models, like the Greenworks, that feature a foldable handle and vertical storage capability, which can drastically reduce the space required in a crowded garage or shed.
- Capacity/Performance: Battery power is measured in Volts (V) and runtime in Amp-hours (Ah). A higher voltage generally means more power, while higher Amp-hours mean longer runtime. For a mower, a brushless motor is a critical feature, offering more power, higher efficiency, and a longer lifespan than older brushed motors. For combo kits, check if all tools share this brushless technology or if some are brushed to manage costs.
- Materials & Durability: The mower deck is the foundation of the machine. A steel deck provides superior durability and rigidity compared to a plastic one, though it adds weight. Pay attention to other components like wheels, handles, and adjustment levers. User feedback can often highlight potential weak points in plastic parts that may not be obvious at first glance.
- Ease of Use & Maintenance: The core appeal of battery power is simplicity. Look for features like a push-button start, single-lever height adjustment, and a variable-speed self-propel system. Long-term maintenance should be minimal—limited to blade sharpening and keeping the underside of the deck clean, which is easier on an electric mower you can safely tip on its side.
Keeping these factors in mind, the Greenworks 21″ Self-Propelled Mower Kit stands out in several areas. You can explore its detailed specifications here.

Unboxing the Greenworks Kit: First Impressions and Assembly
The arrival of the Greenworks 21″ Self-Propelled Mower Kit was met with a mix of excitement and pragmatism. The box is substantial, hinting at the 78-pound machine within. Upon opening it, we were pleased to find the components securely packed and logically arranged. Our experience mirrored that of many users who noted the assembly is incredibly simple. It genuinely takes just a few minutes, primarily involving extending the handle and tightening two sets of bolts. There’s no complex instruction manual to decipher or a bag of confusing parts; it’s designed for immediate, hassle-free setup.
Our first impression of the mower itself was its robust build. The 21-inch deck is made of steel, not plastic, which gives it a satisfying heft and a feeling of durability comparable to its gas-powered cousins. The other tools in the kit—the 12″ string trimmer and 320 CFM blower—are noticeably lighter and feel more like functional, entry-level additions. This is expected, as they utilize brushed motors while the mower boasts a high-efficiency brushless one. The star of this show is undoubtedly the mower, with the other tools serving as a powerful value-add to create a comprehensive yard care ecosystem right out of the box.
What We Like
- The mower’s powerful brushless motor and steel deck handle thick, overgrown grass with ease.
- Excellent value proposition, bundling a mower, trimmer, blower, two high-capacity batteries, and a dual charger.
- Variable-speed self-propel feature makes mowing slopes and large areas much less strenuous.
- Smart, space-saving design allows for vertical storage, freeing up valuable garage floor space.
What We Didn’t Like
- The included string trimmer and leaf blower use less powerful brushed motors.
- Some user reports raise concerns about the long-term durability of certain plastic components and potential charger issues.
Putting the Greenworks Trio to the Test: A Detailed Performance Analysis
An all-in-one kit can look great on paper, but the real test is how each component performs in the wild, untamed environment of a suburban lawn. We put the Greenworks 21″ Self-Propelled Mower Kit through its paces over several weeks, tackling everything from routine maintenance cuts to a post-vacation jungle that had been fueled by a week of rain. This is where the machine’s character truly reveals itself—its power, its endurance, and the synergy of its included tools.
The Mower’s Muscle: Cutting Power and Self-Propel Performance
The heart of this kit is the 21-inch self-propelled mower, and it beats strongly. Powered by two 24V batteries running in series to deliver 48V of power, the brushless motor is impressively potent. On our standard, well-kept lawn, it purred along, leaving clean, even lines. The real test, however, came after we let a patch of lawn grow wild. This is where we expected the battery mower to falter, but it didn’t. Echoing the experience of one user who faced “epic levels” of springtime growth, we found the mower chewed through tall, thick, and even slightly damp grass without stalling. It bogged down slightly in the most challenging patches, a common occurrence for any mower, but the motor’s torque was sufficient to keep the blade spinning and cutting effectively.
The self-propel feature is a game-changer and, in our opinion, a non-negotiable for any mower of this weight. The variable speed control is intuitive, managed by a simple lever on the handle. At its lowest setting, it provides a gentle assist. At its highest—what one ecstatic user aptly called “rabbit mode”—you’re practically jogging to keep up. This power makes tackling inclines or large, flat expanses significantly less fatiguing. The single-lever, 7-position height adjustment is another highlight, allowing for quick and easy changes to the cutting height (from 1-3/8″ to 4”) without fumbling with four individual wheel levers. The large wheels contribute to a smooth ride, easily navigating the bumpy and uneven sections of our test lawn.
Battery Life and Charging: The 48V PowerCore
Power is nothing without endurance. The kit includes two 5.0Ah batteries, which is a generous capacity and a crucial factor in its performance. For a typical quarter-acre suburban lot with moderately tall grass, we were able to complete the entire mow, plus some light trimming and cleanup, on a single charge with power to spare. The runtime claim of “up to 35% longer runtime” seems plausible under ideal conditions. However, when we tackled that overgrown, wet jungle, the mower had to work much harder. In this high-demand scenario, we depleted the batteries before finishing, requiring a recharge to complete the job. This aligns perfectly with a user’s experience of needing to recharge once to get through an exceptionally long post-storm cut.
The included 4A dual-port charger is a fantastic addition. It replenishes both batteries simultaneously, which is a huge convenience. A full recharge from empty took roughly 90 minutes. This is reasonably fast and allows for a quick lunch break before heading out to finish a larger job. It’s important to note, however, that a few users have reported issues with charger malfunctions or one port failing. While we didn’t experience this in our testing, it’s a point of awareness. The overall battery system is robust and provides ample power and sufficient runtime for the vast majority of homeowners this kit is designed for.
Versatility and Storage: Beyond Just Mowing
A great mower should adapt to the needs of your lawn, and the Greenworks 3-in-1 system delivers solid versatility. We tested all three modes: mulching, rear bagging, and side discharge. The mulching function worked very well on dry grass, chopping clippings finely and returning the nutrients to the soil with no visible clumps. The large collection bag is easy to attach and remove, and it filled up effectively during our tests, though its sheer volume can make it heavy when full of dense, wet grass. The side discharge mode is essential for tackling the tallest, most overgrown sections where bagging or mulching would be impractical. As one user noted, the side discharge chute can get clogged with very wet, matted grass, but this is a common issue with nearly any mower under such extreme conditions. A quick, safe clearing of the chute is all that’s needed to get back to work.
Perhaps one of the most celebrated features is the vertical storage capability. After mowing, you simply fold the handle down, and the mower can be tipped back and stored upright against a wall. This reduces its storage footprint by up to 70%, turning it from a space-hogging machine into a compact, easily storable tool. For anyone with a packed garage, this feature alone is a massive selling point and a clear advantage over traditional gas mowers that must be stored flat.
The Supporting Cast: Trimmer and Blower Performance
While the mower is the main event, the included 12-inch string trimmer and 320 CFM blower are what elevate this from a purchase to a complete lawn care solution. It’s critical to note that both of these tools feature brushed motors. This means they don’t have the same top-tier power or efficiency as the mower’s brushless motor, but they are more than capable for their intended tasks. The string trimmer, with its 0.065-inch line and auto-feed head, made quick work of edging along sidewalks and trimming around flower beds and fence posts. It’s lightweight and easy to handle.
The 320 CFM blower generates a 90 MPH airstream, which is perfectly adequate for clearing grass clippings from driveways, patios, and walkways after a mow. It’s also useful for managing dry leaves in the fall, though it may struggle with large, wet piles. The variable speed dial adds a nice touch of control. These tools aren’t designed to compete with high-end, standalone units, but as part of this kit, they are incredibly convenient and effective for post-mowing cleanup, ensuring your entire property looks neat and tidy.
What Other Users Are Saying
Across the board, the sentiment for the Greenworks 21″ Self-Propelled Mower Kit is largely positive, particularly regarding its core function: mowing. Many users share our astonishment at its power. One reviewer declared it a “beast,” noting that it “will chop through” impressively tall and thick grass. Another was “completely impressed with its power” after using it on a friend’s “wildly overgrown lawn,” stating it handled wet, heavy grass about as well as their gas mower. The ease of assembly and push-button start are also frequently praised as a welcome departure from the hassles of gas engines.
However, the feedback isn’t universally glowing, and some criticisms highlight important considerations. The most significant concern revolves around long-term durability, specifically with plastic components. One user shared a frustrating experience: “Didn’t even last one year. Plastic top completely broke off on its own.” Others have reported receiving units with minor defects like a small slit in the collection bag or, more critically, a malfunctioning battery charger right out of the box. These reports, while not widespread, suggest that while the core mechanics are solid, some peripheral components may be prone to failure.
How Does the Greenworks Kit Compare to the Competition?
No product exists in a vacuum. The Greenworks 21″ Self-Propelled Mower Kit is a compelling package, but its value is best understood when compared against other popular options in the lawn care space, each catering to a slightly different user need or philosophy.
1. Greenworks 40V 20″ Twin Blade Mower
- CORDLESS 20” LAWN MOWER – Get more done, faster, with Greenworks electric lawn mowers. This 40V push mower provides the power you need with up to 45 minutes of run-time on a fully charged 4.0Ah...
- LIGHTWEIGHT, EASY TO USE – a lightweight 20” cutting deck allows for easy maneuvering through small to medium yards (up to ½ acre) more efficiently
- TWIN BLADES - offer better cut quality, superior mulching, and bagging capabilities
For those who are sold on the Greenworks ecosystem but may not need the self-propel feature or the full 3-in-1 tool kit, this 40V model is a strong contender. Its twin-blade design provides an excellent mulching cut, and its 20-inch deck is well-suited for smaller yards. It represents a step down in raw power and deck size from our reviewed model, but it’s also lighter and more maneuverable as a push mower. This is an excellent choice for users with flat, smaller lawns who want a quality battery-powered cut without the extra cost and weight of a self-propulsion system.
2. PowerSmart 21-Inch 144cc Gas 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 PowerSmart mower represents the traditional gas-powered alternative. Its 144cc engine provides brute-force power that is undeniable, capable of running all day as long as you have fuel. It appeals to the traditionalist who prioritizes raw cutting torque and isn’t concerned with noise, emissions, or regular maintenance like oil changes and spark plugs. While it matches the Greenworks kit’s mower in cutting width, it lacks the convenience of a push-button start, the quiet operation, and the incredible value of getting a trimmer and blower included in the price.
3. BLACK+DECKER 20-Inch 13-Amp Corded Lawn Mower
- CORDED – Corded design offers unlimited runtime for even the biggest jobs.
- POWERFUL ELECTRIC MOTOR – 13 Amp motor supplies ample power for cutting through thick grass and overgrowth.
- TOOL-FREE HEIGHT ADJUSTMENT – A single lever adjusts the mower deck’s 7-setting cutting height between 1-1/2 in. to 4 in.
The BLACK+DECKER corded mower offers a different kind of convenience: unlimited runtime. As long as it’s plugged in, it will go. It’s typically the most affordable entry point into electric mowing and is extremely lightweight and easy to maintain. However, its primary drawback is significant: the cord. You are perpetually tethered to an outlet and must constantly manage the cord to avoid running over it. This makes it suitable only for very small, simple, and obstruction-free yards. The Greenworks kit offers total freedom from that cord, a trade-off most users find well worth the investment.
The Final Verdict: Is the Greenworks 21″ Self-Propelled Mower Kit the Right Choice for Your Lawn?
After extensive testing and analysis, we can confidently say that the Greenworks 21″ Self-Propelled Mower Kit is a phenomenal value and a top-tier performer for the modern homeowner. It successfully solves the problem of lawn care fragmentation by delivering a powerful, cohesive, and easy-to-use system. The mower is the undeniable star, with its brushless motor, steel deck, and variable-speed self-propel system delivering performance that rivals, and in some ways exceeds, its gas counterparts. The inclusion of a capable trimmer and blower, all powered by the same two high-capacity batteries, transforms it from just a mower into a complete yard maintenance solution.
While the supporting tools are not top-of-the-line, they are more than adequate for post-mowing cleanup. The potential concerns about the durability of some plastic parts and occasional charger issues are valid but seem to be outliers in a sea of positive experiences. For the homeowner with up to half an acre of lawn who wants to ditch gas and cords forever, this kit offers an almost unbeatable combination of power, convenience, and value. It simplifies the work, quiets the noise, and cleans up the process, turning a weekend chore into a far more pleasant task.
