What Sets It Apart
Key specification highlights based on our analysis.
Considerations
Plastic Cutting Deck
Lightweight but less durable than steel; won't rust
Why We Recommend It
- 01.
Brushless 40V motor delivers strong cutting power while maximizing the 4.0Ah battery's 35-minute runtime
- 02.
Lightweight at 46.7 lbs , noticeably easier to push and turn than comparable gas mowers
- 03.
Push-button start means zero pull-cord frustration, even after winter storage
- 04.
6 cutting height positions via single lever (1.25" to 3.375") cover most common lawn care needs
- 05.
Supports both mulching and rear bagging discharge , flexible for different mowing preferences
Considerations
- 01.
35-minute runtime on a single 4.0Ah charge limits coverage to smaller yards; a second battery may be needed for yards over ~5,000 sq ft
- 02.
Plastic cutting deck is lighter than steel but less impact-resistant , avoid heavy debris in the mowing path
- 03.
No self-propelled drive, so slopes and larger areas require full manual effort

Power & Performance
The 40V brushless motor is the key differentiator here , brushless technology runs cooler, more efficiently, and has a longer lifespan than brushed motors, translating to stronger sustained cutting power through the battery charge. Customers report it handles tough and thick grass quietly without bogging down, which speaks to the motor's consistent torque delivery.
For typical suburban lawn grasses (fescue, bluegrass, St. Augustine), this power level is well-matched to routine weekly mowing.
Cutting System
The 17-inch plastic cutting deck is sized right for small yards , narrow enough to navigate gates and tight spaces, but wide enough to mow efficiently without excessive passes. The single-lever height adjustment spans 1.25 to 3.375 inches across 6 positions, covering scalp-short cuts up to a healthy tall-grass height.
Both mulching and rear bagging are supported, giving users the flexibility to return clippings to the lawn or collect them for disposal.
Drive & Handling
This is a push mower , all forward motion comes from the operator, which keeps the design simple, lightweight, and accessible. At 46.7 lbs, it's on the lighter end for a battery push mower, and customers consistently note how easy it is to push and turn.
The front-wheel drive configuration aids in maneuvering around obstacles. On flat to gently rolling terrain, the light weight makes mowing feel natural; on steep slopes, the lack of self-propel assist becomes more apparent.
Battery / Fuel
The included 40V 4.0Ah lithium-ion battery delivers an estimated 35 minutes of runtime per charge , enough to cover approximately 2,000-5,000 sq ft depending on grass density and cutting conditions. Charging time is not specified, so planning for a recharge window between sessions is wise if your yard is near the upper limit.
Compared to gas, there's no fuel to store, no oil to change, and no carb to clean , battery maintenance is limited to proper storage over winter.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with small yards (up to ~5,000-6,000 sq ft) where the 35-minute runtime is sufficient to complete a full mow
- ✓ Eco-conscious users who want zero direct emissions and significantly quieter operation than a gas mower
- ✓ Low-maintenance lawn owners who prefer push-button start and no oil changes, spark plugs, or fuel to manage
- ✓ Suburbanites with flat or gently sloped yards who value a lightweight 46.7 lb mower that's easy to store and maneuver
Not Ideal For
- ✕ Owners of large yards over a quarter acre , the 35-minute battery runtime will likely require mid-mow recharging or a second battery
- ✕ Hilly or steep terrain users who need self-propelled drive assist to manage inclines safely and comfortably
- ✕ Those dealing with overgrown or thick, tall grass regularly, where a higher-voltage or more powerful mower would perform better
Customers consistently report straightforward, tool-minimal assembly that most users complete in under 30 minutes. The push-button start means you're ready to mow immediately after charging the battery.
Charge the 4.0Ah battery fully before first use to condition it and get accurate runtime expectations
Set your cutting height one notch higher than you think you need on the first pass over an established lawn , the 17" deck can scalp uneven ground at lower settings
Greenworks backs this mower with a 3-year warranty on both the tool and the battery , one of the more generous coverage packages in the cordless push mower category. Verify specific terms and registration requirements directly with Greenworks, as warranty activation may require product registration.
FAQ
How long does the battery last on the Greenworks 40V 17" mower?
The included 4.0Ah 40V battery provides approximately 35 minutes of runtime per charge. In practice, customers report this is sufficient for lawns up to around 2,200-5,000 sq ft depending on grass thickness and cutting height.
For larger yards, a second 40V 4.0Ah battery would allow back-to-back mowing without waiting for a recharge.
Is this lawn mower self-propelled or push only?
This is a push lawn mower , there is no self-propelled drive system. However, at just 46.7 lbs, it's light enough that most users find it easy to push on flat to moderately sloped terrain.
If your yard has significant hills, consider a self-propelled model for easier operation.
Does this mower mulch, or does it only bag clippings?
The Greenworks 40V 17" supports both mulching and rear bagging discharge options. Mulching recycles clippings back into the lawn as natural fertilizer, while the rear bag collects clippings for disposal.
A side discharge option is not listed in the specifications.
Is the 40V Greenworks battery compatible with other Greenworks tools?
Yes , Greenworks uses a shared 40V battery platform across many of their cordless outdoor tools. The included 4.0Ah battery is compatible with Greenworks 40V trimmers, blowers, chainsaws, and other tools in the same voltage family, making it a practical platform if you're building a cordless yard tool collection.
How does this mower perform on thick or overgrown grass?
Customers report that the brushless motor handles tough, thick grass quietly and without stalling under normal mowing conditions. For heavily overgrown grass (several inches above normal height), it's best to raise the cutting height to the maximum 3.375" setting for a first pass, then lower and re-mow , this protects both the motor and battery runtime.
What yard size is the Greenworks 40V 17" push mower best suited for?
Greenworks recommends this mower for small yards, and customer feedback confirms it works best on properties up to about 5,000-6,000 sq ft. One customer specifically noted it's ideal for a 2,200 sq ft lawn. Beyond that range, the 35-minute battery runtime may require a mid-session recharge, making a larger-deck or higher-capacity model worth considering.
Bottom Line
The Greenworks 40V 17" Brushless Cordless Lawn Mower is a well-executed battery push mower for small suburban yards. The brushless motor, push-button start, and included 4.0Ah battery make it genuinely low-effort to maintain and use, while the 3-year warranty on both tool and battery adds real value.
Owners of larger yards or steep terrain will hit the limits of the 35-minute runtime and push-only drive, but for its intended use case it's a strong, quiet, eco-friendly performer.
Best for small flat yards under 5,000 sq ft where quiet, zero-emissions, low-maintenance mowing is the priority.
Consider alternatives if your yard exceeds a quarter acre, features steep slopes, or requires more than 35 minutes of continuous mowing per session.
