Key Features & Specifications

Standout Features

After unboxing and assembling the kit, several features immediately stood out as game-changers. Here’s a breakdown of what makes this system unique:

• Smart Pace Self-Propulsion: This isn’t a simple on/off self-propel. The system uses a variable-speed dial and a drive bar that automatically adjusts the mower’s speed to your natural walking pace. It creates an incredibly smooth, almost effortless mowing experience, especially on inclines.
• Brushless Motor Technology: Both the mower and leaf blower utilize brushless motors. This means more torque, less heat generation, significantly quieter operation, and a longer overall tool life compared to brushed motors.
• 3-in-1 Mowing Capability: The mower deck easily converts between mulching, bagging, and side-discharge modes with simple plug adjustments. The included rear bag is generously sized, reducing how often you need to empty it.
• Dual 4.0Ah Battery System: The inclusion of two high-capacity batteries is crucial. While one is in use, the other can be charging, virtually eliminating downtime for most yards and providing the advertised up to 70 minutes of runtime.
• Vertical Storage: The mower is designed to stand on its rear end, with the handle folding down. This saves a massive amount of garage or shed floor space—a huge benefit for those with limited storage.
• Powerful 130 MPH Leaf Blower: This isn’t an afterthought accessory. The blower is genuinely powerful, with a variable speed trigger and a “turbo” button for stubborn, wet leaves. At 550 CFM, it competes with many gas-powered models.
• Easy-Load String Trimmer: The trimmer features an automatic feed spool (AFS) system that advances the dual-line .065″ string as needed, minimizing frustrating bump-and-tap rituals.

When evaluating if the Greenworks 40V lawn mower kit worth it, these features collectively build a strong case for its value proposition over buying tools individually.

What’s Included in the Box

The kit arrives in a large, well-packed box with each component securely nestled in molded cardboard. The unboxing experience feels premium and organized. Here’s the complete itemized list:

• Greenworks 40V 21″ Self-Propelled Lawn Mower (with rear bag, mulching plug, and side discharge chute)
• Greenworks 40V Brushless Leaf Blower (130 MPH / 550 CFM)
• Greenworks 40V 12″ String Trimmer
• Two (2) Greenworks 40V 4.0Ah Lithium-Ion Batteries
• One (1) Dual-Port 40V Charger
• Mower Assembly Hardware (handle bolts, etc.)
• Operator’s Manuals for all three tools

The build quality upon first inspection is impressive. The mower’s steel deck feels solid, the plastic housings are robust without being cheap, and the batteries have a substantial heft. All necessary tools for assembly (a wrench is typically included) are in the box. There are no glaring missing items; it’s a true “ready-to-work” kit. You will need to attach the mower handle, which is a straightforward 15-minute process. This comprehensive package is a key part of the Greenworks 40V pros cons analysis, as it eliminates the need for separate purchases.

How to Use Greenworks 40V 21 Brushless Cordless (Smart Pace) Self-Propelled Electric Lawn Mower, Brushless Leaf Blower (130 MPH / 550 CFM), String Trimmer, (2) 4.0Ah Batteries and Charger: Complete Guide

Step 1: Initial Setup and Installation

1. Unbox all components and lay them out. 2. For the mower, attach the upper handle to the lower handle using the provided bolts and wrench. It’s a simple pin-and-bolt system. 3. Install the rear bag by hooking it onto the designated brackets on the mower deck. 4. Insert a battery into the mower, blower, and trimmer to ensure they click securely into place. 5. Plug the dual-port charger into a standard wall outlet.

Step 2: First-Time User Guide

Before your first mow, fully charge both batteries. To start the mower, insert a battery, press the safety button on the handle, and squeeze the start lever. The mower will not start unless the safety bail (the bar you hold down) is engaged. For the blower and trimmer, simply insert a battery and use the trigger. Familiarize yourself with the mower’s single-lever height adjustment; pull the lever toward you and move it to one of the seven notches to set your cutting height.

Step 3: Core Functions and Daily Use

For mowing, set your desired speed on the Smart Pace dial (1-5). As you walk and hold down the drive bar, the mower will move forward. Release the bar to stop propulsion. Use the deck plug for mulching, attach the side discharge chute for clippings, or use the bag for a clean finish. For trimming, hold the trimmer at a slight angle and use a sweeping motion. The auto-feed head will keep line length optimal. For blowing, use the variable trigger for light debris and press the turbo button (located near your thumb) for maximum power on wet leaves or gravel driveways.

Step 4: Advanced Techniques

Use the “self-propel assist” to start the mower on a slope without it rolling back. For a perfect stripe, mow in alternating directions each week. With the blower, use a low, sweeping motion to gather leaves into piles rather than just scattering them. The trimmer’s head can be rotated 90 degrees for easy edging along sidewalks.

Step 5: Maintenance and Care

After each use, clean grass clippings from under the mower deck (tip the mower back, never on its side, with the battery removed). Wipe down the tools with a dry cloth. Periodically check the trimmer head for tangled line. Store the batteries in a cool, dry place, ideally at a 40-80% charge if storing for more than a month. For detailed seasonal maintenance, see our lawn mower care guide.

Step 6: Troubleshooting Common Issues

Issue: Mower won’t start. Solution: Ensure the battery is fully seated and charged. Check that the safety bail is fully engaged. Issue: Poor cutting performance or ragged grass. Solution: Sharpen or replace the mower blade. Ensure you’re not mowing wet grass or trying to cut too much at once. Issue: Trimmer line not feeding. Solution: Tap the head on the ground while at full speed to trigger the auto-feed. If that fails, manually pull out more line. Following this guide is essential to forming your own Greenworks 40V kit honest opinion based on proper use.

Performance & Real-World Testing

Testing Methodology

We tested this kit over four weeks on a 0.3-acre suburban lot with a mix of Kentucky bluegrass and fescue. Testing included weekly mowing, post-mow trimming, and seasonal leaf cleanup. We measured battery runtime, cutting quality, noise levels, and overall ease of use, comparing the experience directly to a traditional gas-powered mower and trimmer.

Performance Metrics

The performance was consistently impressive. The mower’s brushless motor provided ample torque, even in slightly taller, damp grass. The cut quality was clean and even, rivaling our gas mower. Noise reduction was the most immediately noticeable benefit—conversation at a normal volume is possible while mowing. With two batteries, we completed the entire lawn (mowing and trimming) with about 25% battery remaining, confirming the 70-minute runtime claim for average conditions.

Real-World Scenarios

On a moderate incline, the Smart Pace system shined, providing steady propulsion without lag or surge. The leaf blower handled a late-fall cleanup of dry oak leaves with ease; the turbo mode was necessary for damp, matted leaves in garden beds. The trimmer made quick work of edge trimming and around landscape beds, though very thick, woody weeds required multiple passes.

Claims vs. Reality

Greenworks’s claims largely held up. The 70-minute runtime is achievable under normal mowing conditions (dry grass, reasonable height). The “gas-like power” claim is valid for the mower and blower. The one area where expectations slightly diverged was in very thick, wet grass; like most mowers (including gas), it can bog down and require a slower pace or a higher cut setting. This real-world performance is central to answering should I buy the Greenworks 40V kit.

Pros and Cons

What We Loved (Pros)

• Unmatched Convenience & Quiet Operation: No gas, no oil, no pull cords, and dramatically less noise. Starting is instant and silent.
• Smart Pace is a Game-Changer: The self-propulsion system feels intuitive and reduces fatigue significantly, especially on hills.
• Excellent System Integration: Two batteries power three robust tools seamlessly. The shared battery platform is incredibly convenient.
• Superior Cut and Blow Quality: The mower delivers a manicured, even cut, and the blower has genuine clearing power.
• Space-Saving Vertical Storage: This feature alone justifies the purchase for homeowners with cramped sheds or garages.

What Could Be Improved (Cons)

• Premium Price Point: The initial investment is higher than a basic gas mower, though the long-term savings on fuel and maintenance offset this.
• Battery Management for Large Yards: For properties over 0.5 acres, you might need to pause for a battery recharge mid-job, or consider purchasing an extra battery.
• Plastic Components on Accessories: While the main tools are sturdy, parts like the trimmer’s guard and blower tube feel adequate but not premium.

Greenworks 40V 21 Brushless Cordless (Smart Pace) Self-Propelled Electric Lawn Mower, Brushless Leaf Blower (130 MPH / 550 CFM), String Trimmer, (2) 4.0Ah Batteries and Charger vs. Competitors

How does this kit stack up against other players in the cordless arena? Let’s compare it to two major competitors: the Ego Power+ Select Cut and the Ryobi 40V HP Brushless system.

When to Choose This Product

Choose this Greenworks kit if you want a complete, ready-to-go system with the most intuitive self-propulsion on the market, excellent overall power, and don’t want to piece together tools and batteries separately. It’s the best “out-of-the-box” solution.

When to Consider Alternatives

Consider Ego if your primary concern is having the absolute highest power and cutting performance from the mower itself, and you’re willing to pay a premium and buy tools à la carte. Consider Ryobi if budget is the foremost constraint and you plan to invest heavily in their expansive 40V or 18V ONE+ ecosystem for other tools. For a detailed brand showdown, read our comparison of Ego vs. Greenworks.

Who Should Buy Greenworks 40V 21 Brushless Cordless (Smart Pace) Self-Propelled Electric Lawn Mower, Brushless Leaf Blower (130 MPH / 550 CFM), String Trimmer, (2) 4.0Ah Batteries and Charger?

Ideal For:

• Suburban Homeowners (Up to 0.5 Acres): This is the sweet spot. The battery runtime is perfect, and the system handles all core tasks efficiently.
• Those Seeking Quiet, Fume-Free Operation: Perfect for early morning or evening mowing without disturbing neighbors, and for those sensitive to gas fumes.
• DIYers Who Value Low Maintenance: No more spark plugs, air filters, oil changes, or stale gas. It’s virtually maintenance-free beyond blade sharpening and cleaning.
• Users with Limited Storage Space: The vertical storage capability is a major selling point for townhouses or homes with small garages.

Not Recommended For:

• Owners of Very Large Properties (1+ Acres): Even with extra batteries, the runtime and recharge cycle may become frustrating for extensive mowing.
• Those on an Extremely Tight Budget: While the value is excellent for a kit, the upfront cost is higher than a basic gas mower. If the budget is under $500, consider a corded model or a less comprehensive kit.
• Professional Landscapers: The durability is great for residential use, but daily commercial-grade abuse requires professional-grade equipment.

Expert Tips for Maximum Value

Tip #1: Master the Smart Pace Dial

Don’t just set it to max. Start on a lower setting (2 or 3) to get a feel for the auto-adjust. You’ll use less battery and have more precise control, especially around flower beds.

Tip #2: Mulch for Healthier Grass & Less Work

Use the mulching plug regularly. It returns nutrients to your soil, eliminates bag-emptying stops, and can extend your mowing runtime by up to 20%.

Tip #3: Invest in a Spare Battery or Fast Charger

For peace of mind or slightly larger yards, a third battery or Greenworks’s rapid charger can ensure you’re never waiting. Check the kit page for compatible add-ons often sold together.

Tip #4: Keep the Mower Blade Sharp

A sharp blade is the single biggest factor in cut quality and battery efficiency. Sharpen it at least twice per mowing season.

Tip #5: Store Batteries Indoors in Off-Season

Extreme cold can permanently damage lithium-ion batteries. Store them in a climate-controlled environment during winter months.

Tip #6: Use the Right Tool for the Job

Don’t use the trimmer to tackle small saplings or the blower to move heavy gravel. Using tools within their design limits drastically extends their life.

Tip #7: Leverage the Vertical Storage Daily

Make it a habit. Folding the handle and standing the mower up takes seconds and will transform your storage space.

Common Mistakes to Avoid

1. Mistake: Mowing wet or excessively tall grass. → Solution: Wait for the grass to dry and follow the “one-third rule”—never cut more than one-third of the grass blade height at once.
2. Mistake: Letting batteries fully discharge before charging. → Solution: Charge batteries when they have one bar of power remaining. Deep discharges can shorten overall battery lifespan.
3. Mistake: Forcing the trimmer line into thick obstacles. → Solution: Use a gentle sweeping motion. For very thick weeds, use a dedicated brush cutter attachment or manual tools.
4. Mistake: Storing the mower horizontally with the battery installed. → Solution: Always remove the battery before storing, and utilize the vertical storage feature to prevent deck warping and save space.
5. Mistake: Neglecting to clean the mower deck after mowing. → Solution: A quick scrape or hose-down after each use prevents corrosive grass buildup and ensures proper airflow for a better cut.

Pricing & Where to Buy

The Greenworks 40V lawn mower kit has a current price of $689.44. Compared to buying a comparable self-propelled mower, blower, and trimmer separately (even within the Greenworks ecosystem), this kit represents a significant savings of $150-$200. When you factor in the lifetime savings on gasoline and engine maintenance, the value proposition becomes very strong. The kit is primarily sold through major online retailers and home improvement stores. Amazon often has the most competitive pricing and fast shipping, and it’s an authorized retailer. Be wary of deals that seem too good to be true from unknown sellers, as warranty support may be affected.

Warranty & Support

Greenworks typically offers a 4-year warranty on the mower and blower (tool only) and a 2-year warranty on the string trimmer when purchased from an authorized retailer. The batteries are covered by a 4-year warranty as well. This is an above-average warranty in the cordless tool industry. Customer support is accessible via phone and email, and parts (like blades and trimmer spools) are readily available online. This strong warranty support mitigates risk and adds to the long-term value, making the question of should I buy the Greenworks 40V kit easier to answer affirmatively.

Our Recommendation

We highly recommend the Greenworks 40V Lawn Care Kit. On a scale of 1 to 5, it earns a solid 4.5 out of 5 stars.

Frequently Asked Questions

Is Greenworks 40V 21 Brushless Cordless (Smart Pace) Self-Propelled Electric Lawn Mower, Brushless Leaf Blower (130 MPH / 550 CFM), String Trimmer, (2) 4.0Ah Batteries and Charger worth the money?

Absolutely, for its target user. While the $689 price tag is an investment, you’re getting three commercial-grade tools, two large batteries, and a charger. When you consider the combined cost of a quality self-propelled gas mower, a powerful blower, and a trimmer—plus a lifetime of fuel, oil, and maintenance—this kit offers excellent long-term value and immediate convenience. It’s a classic case of “pay more now, save more later.”

How does it compare to a gas mower?

The kit is complete. The only additional items you might want are a spare trimmer spool (available here), a blade sharpening kit, and perhaps a pair of safety glasses for trimming. No mandatory extra purchases are required.

What warranty and customer support does it offer?

Greenworks provides a strong 4-year warranty on the mower, blower, and batteries, and a 2-year warranty on the trimmer (tool-only). This is industry-leading coverage that demonstrates confidence in their product. Customer support channels are standard and effective for warranty claims and parts.

Where can I buy it at the best price?

We recommend purchasing from this authorized retailer for competitive pricing, authentic products, reliable shipping, and secure warranty validation. Prices can fluctuate, so it’s wise to check the link for current deals.

Can the batteries be used with other Greenworks 40V tools?

Yes, that’s a major advantage. The two 4.0Ah batteries included in this kit are compatible with the entire Greenworks 40V platform. This means you can power their chainsaws, snow blowers, cultivators, and more without buying new batteries.

How do I dispose of the batteries when they eventually wear out?

Do not throw lithium-ion batteries in the trash. Greenworks recommends taking them to a certified battery recycling center. Many home improvement stores (like Home Depot or Lowe’s) and electronics retailers offer free battery recycling drop-off services.
