Introduction
The cordless lawn mower market has exploded in recent years, and for good reason. Homeowners are increasingly looking for alternatives to traditional gas-powered mowers — machines that are quieter, cleaner, and far less demanding in terms of maintenance. Among the many brands competing for your attention in August 2026, Greenworks has carved out a reputation as one of the most reliable names in battery-powered outdoor equipment.
In this in-depth review, we’re taking a close look at the Greenworks 80V 21″ Brushless Cordless Push Lawn Mower, a product that promises gas-like performance without the headaches of fuel, oil, and emissions. Priced at $399 and boasting a solid 4.4 out of 5-star rating across more than 2,600 reviews, this mower has clearly resonated with a large audience. But does it truly live up to the hype?
We’ll break down every aspect of this Greenworks 80V Brushless Cordless Lawn Mower Review — from its brushless motor technology and battery ecosystem to its real-world cutting performance and long-term durability. Whether you’re a first-time buyer shopping for a new mower or a current owner wondering whether to stick with Greenworks for your next upgrade, this review is designed to give you the clarity you need to make a confident purchase decision.
Product Overview
At its core, the Greenworks 80V 21″ Brushless Cordless Push Lawn Mower is designed to be a direct replacement for a standard gas-powered walk-behind mower. It comes bundled with two 2.0Ah 80V batteries and a 30-minute rapid charger, which means you can theoretically mow, swap batteries, charge the depleted one, and keep going with minimal downtime.
Here are the key specifications and features at a glance:
- Voltage Platform: 80V lithium-ion battery system
- Deck Size: 21 inches
- Motor Type: TruBrushless (brushless electric motor)
- Run Time: Up to 60 minutes with two fully charged 2.0Ah batteries
- Height Adjustment: Single-lever, 5-position system
- Mowing Modes: 3-in-1 — mulching, rear bagging, and side discharge
- Start Type: Push-button electric start
- Charger: 30-minute rapid charger included
- Ecosystem Compatibility: 75+ Greenworks 80V tools
- Rating: 4.4 / 5 stars (2,644 reviews)
- Price: $399
The inclusion of two batteries and a rapid charger at this price point is notable. Many competitors in the cordless mower space either sell batteries separately or include only a single battery with a slower charger. Greenworks’ approach here is clearly aimed at eliminating range anxiety — the fear that your mower will die halfway through the job.
Perhaps the most compelling aspect of this product, however, is its place within the broader Greenworks 80V ecosystem. With over 75 compatible tools — including string trimmers, leaf blowers, chainsaws, snow blowers, and more — purchasing this mower effectively gives you a gateway into an entire battery-powered yard care arsenal. If you already own other Greenworks 80V tools, this mower shares the same batteries, which adds tremendous value and reduces long-term cost.
Pros: Why This Mower Stands Out
1. Impressive Brushless Motor Performance
The TruBrushless motor is the heart of this mower, and it delivers. Brushless motors are fundamentally superior to their brushed counterparts in several ways: they generate up to 2x more torque, run more efficiently, produce less heat, and last significantly longer. In practical terms, this means the Greenworks 80V mower cuts through thick, wet grass with surprising authority — a task that has historically been the Achilles’ heel of battery-powered mowers. The motor also runs noticeably quieter than a gas engine, which is a welcome quality-of-life improvement for both the operator and the neighbors.
2. Genuine Gas-Like Cutting Performance
Greenworks doesn’t use the phrase “gas-like performance” lightly with this model. The combination of the 80V platform and the brushless motor produces enough power to handle most residential lawn conditions with ease. Whether you’re tackling a weekly maintenance cut on a well-manicured lawn or pushing through a week’s worth of overgrown grass, this mower holds its own. It won’t match the raw, unrelenting power of a high-end commercial gas mower, but for the vast majority of homeowners with yards up to a half-acre, it’s more than sufficient.
3. Excellent Battery Ecosystem and Value
At $399, the inclusion of two 2.0Ah batteries and a 30-minute rapid charger represents genuine value. Many competing products at this price point include only one battery, leaving you stranded if you have a larger yard or if the grass is particularly demanding. The rapid charger is especially useful — it can bring a depleted battery back to full charge in roughly 30 minutes, which means one battery can be charging while you mow with the other. Furthermore, these batteries are compatible with 75+ Greenworks 80V tools, making every subsequent tool purchase more affordable since you won’t need to buy additional batteries.
4. Effortless 5-Position Height Adjustment
The single-lever, 5-position height adjustment is a small but significant convenience feature. Rather than fiddling with individual wheel adjustments, you can change the cutting height with one hand in seconds. This makes it easy to adapt to different grass types, seasons, and aesthetic preferences. Whether you prefer a close, golf-course-style cut or a longer, more natural look, switching between settings is quick and intuitive.
5. Versatile 3-in-1 Design
The 3-in-1 functionality — mulching, rear bagging, and side discharge — gives you flexibility in how you manage grass clippings. Mulching returns finely chopped clippings to the lawn as natural fertilizer, bagging gives you a clean, manicured appearance, and side discharge is useful when grass is tall and you don’t want to clog the bag. Having all three options available means this mower adapts to your preferences rather than forcing you into a single mowing style.
6. Virtually Maintenance-Free Operation
One of the strongest selling points of any cordless mower is the elimination of gas-engine maintenance. With the Greenworks 80V, there’s no oil to change, no spark plugs to replace, no fuel to mix, and no carburetor to clean. The push-button start eliminates the frustration of pull cords, and the brushless motor requires virtually no servicing over its lifespan. For homeowners who view yard work as a chore, this reduction in maintenance is a major quality-of-life improvement.
7. Strong Brand Reliability and Warranty Support
Greenworks has been a consistent player in the cordless outdoor power equipment space for over a decade. The company offers a solid warranty on its 80V products, and its customer service infrastructure is well-established. With a 4.4-star rating across more than 2,600 reviews, the product has a strong track record of customer satisfaction, which provides added confidence for prospective buyers.

Cons: Where This Mower Falls Short
1. Push-Only Design May Fatigue Larger Yards
This model is a push mower, meaning it lacks self-propulsion. For flat, small-to-medium lawns, this is perfectly fine. However, if your yard has slopes, uneven terrain, or exceeds a quarter-acre, you may find yourself working harder than you’d like. Greenworks does offer self-propelled models in its 80V lineup, but they come at a higher price point. For some buyers, the lack of self-propulsion at $399 may feel like a missed opportunity.
2. 2.0Ah Batteries Offer Limited Run Time for Large Yards
While two 2.0Ah batteries provide up to 60 minutes of combined run time, that figure is optimistic and assumes ideal conditions. In reality — with thick grass, tall growth, or hilly terrain — you may see run times closer to 40-45 minutes total. For homeowners with yards larger than a third of an acre, you may need to invest in additional batteries (which are not inexpensive) to complete the job in a single session. Upgrading to 4.0Ah or 5.0Ah batteries is an option, but it adds to the overall cost.
3. Mulching Performance Is Good, Not Great
While the 3-in-1 design is versatile, several users have noted that the mulching capability is adequate but not exceptional. In very thick or wet grass, the mower may leave visible clumps of clippings rather than distributing them evenly. This is a common limitation among cordless mowers in general, but it’s worth noting if mulching is your primary mowing style and you have a particularly lush lawn.
4. No headlights or advanced features
At this price point, some competing models include features like LED headlights for early morning or evening mowing, USB charging ports, or digital displays showing battery life and motor load. The Greenworks 80V push mower is a straightforward, no-frills machine. While it does its core job well, buyers looking for premium convenience features may find the offering a bit basic.
5. Plastic Deck Construction
The mower deck is made of high-impact polymer (plastic) rather than steel. While this keeps the weight down and eliminates concerns about rust, it may raise durability concerns for buyers who plan to use the mower in rough conditions or store it in less-than-ideal environments. A steel deck would inspire more confidence in long-term structural integrity, though it would also add weight and cost.
Customer Reviews Analysis
With a 4.4 out of 5-star rating across 2,644 reviews, the Greenworks 80V 21″ Brushless Cordless Push Lawn Mower enjoys a strongly positive reputation among buyers. Let’s examine what the majority of customers are saying — both the praise and the criticism.
What Customers Love
The most frequently praised aspects of this mower include its ease of use, quiet operation, and surprising power. Many reviewers express genuine surprise at how well the mower handles grass that they previously thought required a gas mower. The push-button start is consistently highlighted as a favorite feature, with multiple reviewers noting the sheer joy of starting their mower with a single press rather than wrestling with a pull cord. Battery life also receives positive marks from owners with small to medium-sized yards, who report being able to complete their mowing in a single charge cycle.
Customers who are already part of the Greenworks ecosystem particularly appreciate the battery compatibility. Several reviewers mention that they purchased this mower to complement an existing collection of Greenworks 80V tools, and the shared battery platform represents significant savings and convenience.
What Customers Criticize
The most common complaints revolve around battery run time on larger or thicker lawns. Some customers report that the included 2.0Ah batteries don’t last as long as they expected, particularly when dealing with tall or dense grass. A smaller subset of reviewers mention that the mulching performance leaves something to be desired, with clumping occurring in wet or overgrown conditions. A few customers have also noted that the mower struggles slightly on steep inclines, which is compounded by the lack of self-propulsion.
Build quality receives mixed feedback. While most customers find the mower to be well-constructed for its price, a handful of reviewers have experienced issues with the grass bag attachment or the height adjustment lever over time. These appear to be isolated incidents rather than widespread defects, but they are worth noting.
Overall Sentiment
The overwhelming majority of reviews are positive, with most buyers recommending the product to others. The consensus is that the Greenworks 80V 21″ mower is an excellent value for homeowners with small to medium-sized lawns who want a reliable, low-maintenance alternative to gas. Buyers with larger properties or particularly demanding grass conditions tend to be less satisfied, often recommending the purchase of additional batteries or upgrading to a higher-capacity model.
Frequently Asked Questions
How long does the Greenworks 80V mower last on a single charge?
Greenworks advertises up to 60 minutes of combined run time using both included 2.0Ah batteries. In real-world conditions, most users report 40 to 55 minutes of actual mowing time, depending on grass thickness, cutting height, and terrain. For best results, it’s advisable to keep both batteries charged and swap them as needed during your mowing session.
Is the Greenworks 80V mower self-propelled?
No, this specific model is a push mower. It does not feature self-propulsion. If self-propulsion is important to you — particularly for hilly terrain or larger yards — Greenworks offers self-propelled models within its 80V lineup at a higher price point.
Can I use this mower on wet grass?
While the mower can technically cut wet grass, it’s not ideal. Wet grass is heavier, clumpier, and more likely to clog the mulching system or grass bag. For the best results and longest battery life, mowing dry or slightly damp grass is recommended. If you must mow wet conditions, using the side discharge mode can help prevent clogging.
Are the batteries compatible with other Greenworks tools?
Yes. This mower uses the Greenworks 80V battery platform, which is compatible with over 75 tools in the Greenworks 80V lineup, including string trimmers, leaf blowers, chainsaws, snow blowers, hedge trimmers, and more. This cross-compatibility is one of the strongest arguments for investing in the Greenworks ecosystem, as it reduces the need to purchase separate batteries for each tool.
How does this compare to a gas mower?
The Greenworks 80V mower delivers performance that is comparable to most residential gas mowers in terms of cutting power and quality. It will not match the extreme power of commercial-grade gas equipment, but for typical suburban lawns, the difference is negligible. The key advantages over gas are quieter operation, zero emissions, no fuel costs, and virtually no maintenance. The main trade-off is run time — a gas mower can run indefinitely as long as you have fuel, while a cordless mower is limited by battery capacity.
Who Should Buy This Product
The Greenworks 80V 21″ Brushless Cordless Push Lawn Mower is best suited for:
- Homeowners with small to medium-sized lawns (up to approximately one-third of an acre) who want a reliable, low-maintenance mowing solution.
- Environmentally conscious buyers who want to eliminate gas, oil, and emissions from their yard care routine.
- Noise-sensitive users — including those in neighborhoods with strict noise ordinances or who prefer to mow early in the morning or late in the evening.
- Existing Greenworks 80V tool owners who want to expand their battery-powered arsenal with a mower that shares their existing batteries.
- First-time mower buyers who want a simple, no-fuss machine that starts with the push of a button and requires virtually no mechanical knowledge to maintain.
- Older adults or anyone seeking reduced physical effort — the lighter weight compared to gas mowers and the elimination of pull-starting make this an accessible option.
This mower may not be the best fit for homeowners with large properties (over half an acre), very hilly terrain, or those who need commercial-grade cutting power. In those cases, investing in a self-propelled model with higher-capacity batteries — or even a gas-powered alternative — may be more practical.
Final Verdict
The Greenworks 80V 21″ Brushless Cordless Push Lawn Mower is a well-executed product that delivers on its core promises. At $399, it offers a compelling combination of power, convenience, and value — especially considering the inclusion of two batteries and a rapid charger. The brushless motor provides genuinely impressive cutting performance, the 3-in-1 design adds versatility, and the virtually maintenance-free operation is a significant lifestyle upgrade over gas-powered alternatives.
It’s not perfect. The push-only design limits its appeal for larger or hillier yards, the 2.0Ah batteries may leave some users wanting more run time, and the mulching performance, while good, doesn’t quite match the best gas mowers in the business. But for its target audience — homeowners with manageable lawns who prioritize ease of use and low maintenance — this mower hits a sweet spot that few competitors can match at this price.
With a 4.4-star rating and a track record of customer satisfaction across more than 2,600 reviews, the evidence strongly supports the conclusion that this is one of the best cordless lawn mowers available in the under-$400 category in 2026. If you’re looking to make the switch from gas to electric, this Greenworks mower is an excellent place to start.
Rating: 4.4 / 5 — Highly Recommended for Small to Medium Lawns
