Power & Performance
The 40V brushless motor at the heart of this lawn mower delivers efficient, consistent power well-suited for routine cuts on maintained grass in small yards. Brushless motor technology means more torque-to-size ratio than brushed alternatives, quieter operation, and a longer motor lifespan since there are no carbon brushes to wear down.
For standard lawn maintenance on flat, well-kept turf, the motor handles the job cleanly without bogging down.
Cutting System
The 14-inch steel cutting deck is compact by design, making this mower a natural fit for narrow gate access, tight corners, and landscaping with obstacles. Cutting height adjusts across 5 positions , from 1.25 inches to 3.375 inches , using a single lever for quick transitions between settings.
The mower supports both rear bag collection and mulching discharge, letting you choose between a clean finish or returning nutrients to the lawn.
Drive & Handling
At 36.4 lbs, this push lawn mower is one of the lighter options in the cordless category, making it easy to maneuver on flat surfaces and simple to lift over steps or obstacles. The push-only drive is best suited to level terrain; users with even mild slopes will feel the difference without self-propelled assistance.
The handle and compact footprint combine to make it genuinely nimble in tight spaces where larger mowers can't reach.
Battery / Fuel
The included 40V 4.0Ah battery delivers up to 45 minutes of runtime per charge , sufficient for most small lots on a single battery. The Greenworks 40V platform means this battery is compatible with other tools in the ecosystem, adding flexibility if you already own Greenworks equipment.
No fuel mixing, no oil changes, and no carburetor issues to worry about; charge time should be verified against the included charger specs for planning back-to-back mowing sessions.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with small yards (under 1/4 acre) , the 14" deck and 45-minute runtime are perfectly sized for compact lots
- ✓ Eco-conscious users wanting zero direct emissions and quieter operation compared to gas lawn mowers
- ✓ Low-maintenance seekers who want to skip oil changes, spark plugs, and fuel stabilizer entirely , push-button start and done
- ✓ Renters or condo owners with a small patch of grass who need a lightweight, easy-to-store mower
Not Ideal For
- ✕ Owners with hilly or sloped terrain , the push-only drive offers no propulsion assist on inclines
- ✕ Medium-to-large yard owners (1/2 acre or more) , the 14" deck and single-battery runtime will require too many passes and recharges
- ✕ Users with thick, overgrown, or tall grass , a 3.375" max cutting height and compact motor may struggle with heavy-duty clearing
Assembly is minimal and typically takes around 5 minutes , most users report simply attaching the handle and snapping in the battery before their first cut. No tools are required for the basic setup.
Fully charge the 4.0Ah battery before your first use to maximize initial runtime and battery longevity
Set your cutting height one notch higher than usual for the first pass on an overgrown lawn to reduce motor strain
Greenworks backs this mower with a 3-year warranty on both the tool and the battery , a strong coverage commitment that exceeds many competing brands. For specific claim procedures or extended coverage options, verify directly with Greenworks customer support at the time of purchase.
FAQ
How long does the battery last on the Greenworks 40V 14" lawn mower?
The included 4.0Ah 40V battery provides up to 45 minutes of runtime per charge under typical conditions. For most small yards under 1/4 acre, that's enough to complete the job on a single charge.
Thicker grass or frequent blade engagement can reduce runtime slightly.
Is this lawn mower self-propelled or push-only?
This is a push lawn mower , there is no self-propelled drive system. It's designed for flat or gently sloped small yards where manual pushing is easy given the mower's 36.4 lb weight.
If you have hills or a larger property, a self-propelled model would be a better fit.
Can this mower mulch grass clippings or does it only bag?
Yes, this mower supports both mulching and rear bag collection. Mulching mode chops clippings finely and returns them to the lawn as natural fertilizer, while the rear bag collects clippings for disposal.
You can switch between modes depending on your preference or grass conditions.
How does the 14" cutting deck compare to standard lawn mowers?
The 14-inch deck is narrower than the typical walk-behind mower average of around 18 inches, which means you'll make more passes to cover the same area. This is a deliberate tradeoff , the compact deck makes this mower significantly more maneuverable in tight spaces, around raised beds, and through narrow gates.
For small yards, the extra passes are a minor inconvenience compared to the handling benefits.
Is the Greenworks 40V battery compatible with other Greenworks tools?
Yes , the 40V 4.0Ah battery included with this mower is part of Greenworks' 40V platform, which is compatible across a wide range of Greenworks lawn and garden tools. If you already own other 40V Greenworks tools, you can share batteries between them, which is a practical advantage for homeowners building out a cordless yard tool collection.
How much assembly does this lawn mower require?
Assembly is very light , most users report completing setup in approximately 5 minutes right out of the box. The process typically involves attaching the handle and installing the battery; no significant mechanical assembly is required.
It's beginner-friendly and doesn't require specialized tools.
Bottom Line
The Greenworks 40V 14" Brushless Cordless Lawn Mower is a well-matched tool for small-yard homeowners who want the convenience of cordless power, the simplicity of push-button start, and the peace of mind of a 3-year warranty , all in a lightweight, easy-to-store package. It won't replace a self-propelled or wide-deck mower for larger properties, but for its intended use case it's hard to beat.
If your yard is compact, flat, and you're done dealing with gas maintenance, this mower deserves serious consideration.
Best for small flat yards under 1/4 acre where lightweight handling, zero emissions, and low maintenance are the priority.
Consider alternatives if your yard has significant slopes, exceeds 1/4 acre, or you regularly deal with thick or overgrown grass that demands more cutting width and power.
