Pros: What We Love About the Greenworks 40V 16″ Mower
1. Ultra-Lightweight and Easy to Maneuver
One of the standout features of this mower is its remarkably low weight. Greenworks claims it is 35% lighter than steel deck mowers, and that difference is immediately noticeable the moment you push it across your lawn. For homeowners who struggle with heavy gas mowers — or anyone who needs to carry the mower up steps or into a tight storage space — this lightweight design is a genuine game-changer. You can easily navigate around flower beds, garden obstacles, and tight corners without the fatigue that comes with heavier machines.
2. Effortless Push-Button Start
Say goodbye to yanking a pull cord. The push-button start on this Greenworks mower fires up instantly every single time. There’s no priming, no choking, and no wrestling with a stubborn engine on cold mornings. This alone is one of the most appreciated features among users who have transitioned from gas-powered mowers. It’s a small convenience that makes a big difference in your weekly mowing routine.
3. Virtually Maintenance-Free Operation
This is where battery-powered mowers truly shine, and the Greenworks 40V is no exception. There is no gas to mix, no oil to change, no spark plugs to replace, and no air filters to clean. Over the lifespan of the mower, the time and money saved on routine maintenance can be substantial. For busy homeowners who simply want to mow the lawn without thinking about engine upkeep, this is a major selling point.
4. Quiet Operation
If you’ve ever been glared at by a neighbor for mowing at 8:00 AM on a Saturday, this mower will be your peacekeeper. The Greenworks 40V operates at a significantly lower noise level compared to gas mowers. You can comfortably mow early in the morning or later in the evening without disturbing your household or your neighbors. It’s also much easier on your ears, reducing the need for hearing protection during extended mowing sessions.
5. Versatile 2-in-1 Mulching and Rear Bagging
The 2-in-1 system gives you the flexibility to either mulch clippings back into the lawn for natural fertilization or collect them in the rear bag for a cleaner look. Switching between modes is straightforward, and both options perform well for their intended purpose. For most homeowners with average lawn conditions, this dual functionality covers all the bases without needing to purchase a separate side-discharge attachment.
6. Single-Lever 5-Position Height Adjustment
Adjusting the cutting height is quick and painless thanks to the single-lever design. Rather than fiddling with individual wheels, one lever adjusts all four wheels simultaneously across five height positions. This makes it easy to adapt to different grass types and seasonal growth patterns. Whether you’re cutting tall spring growth or maintaining a short summer cut, switching heights takes just seconds.
7. Massive Ecosystem Compatibility
One of the smartest aspects of investing in the Greenworks 40V platform is the compatibility with over 75 tools. The same battery that powers this mower can also run trimmers, blowers, chainsaws, snow blowers, and much more. If you’re building out a full suite of cordless outdoor power equipment, the cost savings from sharing batteries across multiple tools are significant. This ecosystem approach also future-proofs your investment — you’re not locked into a single-use battery.
Cons: Where the Greenworks 40V 16″ Falls Short
1. Limited Cutting Width for Larger Yards
At just 16 inches of cutting width, this mower is best suited for small to medium lawns. If you have a yard approaching or exceeding one-third of an acre, expect noticeably longer mowing times compared to wider-deck mowers (20 inches or more). The smaller deck means more passes to cover the same area, which can turn a quick mow into a time-consuming chore on larger properties.

2. Battery Life May Require Planning on Thicker Grass
While the included 4.0Ah battery is rated for up to one-third of an acre, real-world battery life varies significantly based on grass height, thickness, moisture, and how frequently you overlap your mowing passes. Users with thick, fast-growing grass or hilly terrain have reported that the battery can run out before completing their full yard. If your lawn conditions are demanding, you may want to budget for a second battery — which adds to the overall cost.
3. Plastic Deck Construction
The lightweight design comes with a trade-off: the deck is made of polymer plastic rather than steel. While this keeps the weight down and eliminates rust concerns, it may not be as durable over the long term, particularly if you frequently encounter rocks, sticks, or other debris that could crack or chip the deck. For homeowners with rough or debris-laden yards, a steel deck mower may hold up better over years of hard use.
4. No Self-Propelled Option
This is a push mower only. While the lightweight design makes pushing manageable on flat terrain, homeowners with hilly or uneven yards may find themselves working harder than they’d like. If self-propulsion is a must-have feature for your property, you’ll need to look at higher-end models in the Greenworks lineup or competing brands.
5. Rear Bag Capacity Is Modest
The rear collection bag, while functional, is relatively small. If you prefer bagging over mulching, expect to empty it frequently, especially during peak growing season when grass clippings accumulate quickly. This adds time and effort to your mowing routine and may be frustrating for users who prioritize a bagged finish.
Customer Reviews Analysis
With over 12,000 reviews and a cumulative rating of 4.2 out of 5 stars, the Greenworks 40V 16″ Cordless Lawn Mower has been thoroughly vetted by a large and diverse user base. Here’s what the collective feedback tells us:
What Customers Love
The most frequently praised aspects among verified buyers include the ease of use, lightweight design, and quiet operation. Many reviewers specifically highlight how refreshing it is to simply press a button and start mowing without dealing with gas, oil, or pull cords. First-time cordless mower owners are particularly enthusiastic, often noting that the transition from gas to battery was smoother than expected.
Several reviewers also commend the cut quality, noting that for a mower in this price range, the Greenworks delivers a clean, even cut on well-maintained lawns. The mulching capability receives generally positive marks, with users reporting that clippings are finely chopped and decompose quickly.
What Customers Criticize
The most common complaints center around battery runtime limitations. Users with larger yards or thick grass frequently mention that the included 4.0Ah battery doesn’t quite last long enough to finish their entire lawn in one charge. This is a recurring theme in the lower-star reviews and represents the single biggest point of frustration among otherwise satisfied customers.
A smaller subset of reviewers have raised concerns about build quality and durability. Some users report issues with the height adjustment lever becoming loose over time, or the plastic deck showing wear after a couple of seasons of heavy use. However, these complaints appear to be in the minority, and many long-term users report that the mower holds up well with reasonable care.
Additionally, a handful of reviewers note that customer service and warranty claims can be slow to resolve, which is worth considering if you prioritize responsive after-sales support.
Overall Sentiment
The overwhelming majority of reviews are positive, with the mower earning strong marks for its value proposition. For homeowners with small to medium yards who are looking for an affordable, low-maintenance entry into cordless mowing, the consensus is clear: the Greenworks 40V 16″ delivers solid performance at a competitive price point.
Frequently Asked Questions
How long does the battery last on a single charge?
The included 4.0Ah battery provides approximately 45 minutes to 1 hour of runtime under typical conditions, which is sufficient for up to one-third of an acre. However, actual runtime depends heavily on grass height, thickness, moisture content, and your mowing pace. Thick or overgrown grass will drain the battery faster, while well-maintained, shorter grass will allow for longer run times. If you need extended runtime, purchasing an additional 4.0Ah or larger battery is recommended.
Can this mower handle thick or tall grass?
The Greenworks 40V 16″ handles moderately thick grass reasonably well, but it’s not designed for extreme conditions. If your lawn has been neglected and the grass is very tall or dense, you may experience reduced cutting performance and faster battery drain. For best results, it’s advisable to mow regularly and avoid letting grass grow too tall between sessions. Using the highest blade setting for initial passes on overgrown grass, followed by a second pass at your desired height, can help manage tougher conditions.
Is the battery compatible with other Greenworks tools?
Yes. The 40V battery included with this mower is fully compatible with over 75 Greenworks 40V tools, including string trimmers, leaf blowers, chainsaws, hedge trimmers, snow blowers, and more. This cross-compatibility is one of the biggest advantages of the Greenworks 40V ecosystem, allowing you to share batteries across your entire collection of cordless outdoor power equipment.
How does this compare to a gas mower in terms of cutting power?
For regular maintenance mowing on a well-kept lawn, the Greenworks 40V performs comparably to most residential gas mowers in its class. You’ll get a clean, even cut on typical suburban grass. However, it may struggle with extremely thick, wet, or overgrown grass where a gas mower’s sustained torque would have an advantage. For the vast majority of homeowners who mow on a weekly or biweekly schedule, the cutting power is more than adequate.
What is the warranty coverage?
Greenworks backs this mower with a 3-year limited warranty, which covers defects in materials and workmanship. The battery typically carries its own separate warranty period. It’s advisable to register your product upon purchase and keep your receipt to streamline any potential warranty claims. While the warranty period is competitive for this price range, some users have noted that the claims process can be slow, so patience may be required if issues arise.
Who Should Buy This Product?
The Greenworks 40V 16″ Cordless Lawn Mower is an excellent choice for:
- Homeowners with small to medium-sized yards (up to approximately 1/3 acre) who want a simple, no-fuss mowing solution.
- First-time cordless mower buyers who are transitioning from gas and want an affordable, low-risk entry point into battery-powered lawn care.
- Older adults or anyone with physical limitations who benefit from a lightweight, easy-to-push mower with effortless push-button starting.
- Noise-sensitive users who live in close proximity to neighbors or need to mow during non-traditional hours.
- Greenworks 40V ecosystem users who already own other tools in the platform and want to maximize their battery investment.
- Budget-conscious shoppers looking for a reliable, brand-name cordless mower without the premium price tag of self-propelled or wide-deck models.
This mower is not ideal for:
- Homeowners with yards significantly larger than 1/3 acre who need extended runtime and wider cutting paths.
- Users with hilly or uneven terrain who require self-propulsion.
- Those who frequently encounter heavy debris, rocks, or rough conditions that demand a more rugged steel deck construction.
Final Verdict
The Greenworks 40V 16″ Cordless Lawn Mower is a well-rounded, budget-friendly cordless mower that delivers where it matters most for its target audience. It’s lightweight, quiet, virtually maintenance-free, and backed by one of the most versatile battery ecosystems in the cordless outdoor power equipment market. At a price point of around $291, it represents solid value for homeowners with small to medium-sized lawns who want a reliable, no-hassle mowing experience.
It’s not without its limitations — the 16-inch deck and moderate battery life mean it’s not the right tool for every yard, and the plastic construction may give pause to those who prioritize long-term ruggedness. But for the price, the feature set, and the overwhelmingly positive reception from over 12,000 verified buyers, this mower earns a confident recommendation as one of the best entry-level cordless mowers available in 2026.
If your lawn fits within its capabilities, the Greenworks 40V 16″ is a smart, future-proof investment that will save you time, effort, and money on maintenance for years to come.
