What Sets It Apart
Key specification highlights based on our analysis.
Considerations
Polymer Cutting Deck
Lightweight but less durable than steel; won't rust
30-Minute Runtime
Below-average runtime (database avg: 52.7 min)
Why We Recommend It
- 01.
Push-button start eliminates the frustration of pull-cord starting, especially for users with limited upper body strength
- 02.
33.5 lb weight is well below the gas-mower average, making lifting, storing, and maneuvering around obstacles noticeably easier
- 03.
16" deck size is purpose-built for compact yards and tight spaces between garden beds and fences
- 04.
Zero direct emissions and quieter operation than gas , suitable for early morning mowing without disturbing neighbors
- 05.
3-year warranty on both the tool and 4.0Ah 40V battery is above average in this tier
Considerations
- 01.
30-minute runtime is below the category average of ~53 minutes , larger small yards (5,000-10,000 sq ft) may require recharging mid-job
- 02.
Polymer cutting deck, while rust-proof and lightweight, is less impact-resistant than steel decks on rough terrain with debris
- 03.
Push-only design means no self-propelled assist , tiring on uneven or sloped lawns without drive support

Power & Performance
The brushless 40V motor delivers cleaner, more efficient power than brushed alternatives , brushless designs run cooler, last longer, and extract more usable runtime from the 4.0Ah battery. For dry, regularly maintained grass in small yards this motor handles the task confidently.
In thick or damp conditions, however, the 30-minute ceiling limits how much territory you can realistically tackle before the battery needs a 120-minute recharge.
Cutting System
The 16-inch rotary deck is made from polymer rather than steel, keeping weight low and eliminating rust entirely , a genuine advantage for users who store their mower outdoors or in humid conditions. Cutting height adjusts across 5 positions from 1.25 to 3.375 inches via a single lever, covering typical lawn care needs.
Both mulching and rear bagging are supported, giving users flexibility to feed clippings back into the lawn or collect them for disposal.
Drive & Handling
At 33.5 lbs this is one of the lighter cordless mowers on the market, and the compact 16" deck makes maneuvering around flower beds, trees, and narrow side yards genuinely easy. There is no self-propelled drive , this is a push mower , so handling on flat terrain is effortless but moderate inclines will add to user effort.
The handle design is standard for this class; no standout ergonomic features, but nothing problematic reported.
Battery / Fuel
The included 40V 4.0Ah battery is part of Greenworks' 40V platform, compatible with 75+ tools , a meaningful value add if you already own or plan to buy other Greenworks equipment. Runtime caps at approximately 30 minutes per charge, which is below the ~53-minute average for cordless mowers in this category.
The 120-minute full recharge time means back-to-back mowing of larger areas requires either a second battery or patience.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with yards up to ~5,000 sq ft who can complete a mow within the 30-minute runtime window
- ✓ Eco-conscious users wanting zero direct emissions and quieter operation compared to gas mowers
- ✓ Users who prioritize low maintenance , no oil changes, no spark plugs, no fuel stabilizer needed
- ✓ Apartment dwellers or homeowners with limited storage who need a compact, lightweight mower that's easy to lift and tuck away
Not Ideal For
- ✕ Owners of medium-to-large yards (over 10,000 sq ft) where the 30-minute runtime will require multiple charges or battery swaps
- ✕ Users with hilly or sloped terrain who would benefit from a self-propelled drive system to reduce physical effort
- ✕ Those who frequently encounter thick, overgrown, or wet grass that demands more sustained cutting power than a 40V system delivers
Most users report straightforward assembly with basic tool-free or minimal-tool steps; the mower is typically ready to use within 15-20 minutes out of the box. Push-button start means there's no priming, choking, or pull-cord ritual , insert the battery, press the button, and mow.
Set your cutting height before the first use , the single-lever adjustment is easiest to access when the mower is on a flat surface
Charge the battery fully before the first mow to calibrate runtime expectations and ensure the battery management system initializes correctly
Greenworks covers this mower with a 3-year warranty on both the tool and the 4.0Ah battery , one of the stronger warranty packages in the cordless mower segment. Verify current warranty terms and registration requirements directly with Greenworks, as coverage conditions may vary by region.
FAQ
How long does the battery last on the Greenworks 40V 16" mower?
The included 4.0Ah 40V battery provides approximately 30 minutes of runtime per charge. That's enough to cover most small yards under 5,000 sq ft in one session.
Recharging takes about 120 minutes, so plan accordingly if your yard requires more than one pass.
Is the Greenworks 40V 16" mower self-propelled?
No , this is a push mower with no self-propelled drive. For flat, compact yards this is rarely an issue given the 33.5 lb weight, but users with sloped or hilly terrain will need to supply all the forward momentum themselves.
If you need drive assist, look at Greenworks' self-propelled 40V models.
Can this mower bag and mulch grass clippings?
Yes, it supports both rear bagging and mulching. Mulching mode recycles clippings back into the lawn as a natural fertilizer, while the included rear bag collects clippings for disposal.
Side discharge is not listed as a supported option.
Is the Greenworks 40V 40V battery compatible with other Greenworks tools?
Yes , the 40V battery platform is compatible with 75+ Greenworks tools including blowers, trimmers, chainsaws, and more. If you're building out a battery-powered yard care toolkit, this mower is a practical entry point into that ecosystem.
How heavy is the Greenworks 40V 16" cordless mower?
The mower weighs 33.5 lbs with the battery installed, which is meaningfully lighter than most gas mowers and many larger cordless competitors. This makes lifting it over steps, loading it into a vehicle, or storing it on a shelf much more manageable.
What size yard is the Greenworks 40V 16" mower designed for?
Greenworks rates it for yards up to 21,780 sq ft (half an acre), but that figure assumes ideal conditions and potentially multiple battery charges. Realistically, the 30-minute runtime per charge makes it best suited for yards in the 2,000-6,000 sq ft range where a single charge comfortably covers the full area.
Bottom Line
The Greenworks 40V 16" Brushless Cordless Mower earns its place as a top pick for small-yard owners who want gas-free simplicity, a lightweight design, and long-term platform value from the 40V battery ecosystem. The 30-minute runtime is its most notable constraint , users with larger lawns or thicker grass will feel that ceiling.
For the right yard, though, the push-button convenience, 3-year warranty, and near-zero maintenance make it a genuinely satisfying mower to own.
Best for flat suburban yards under 6,000 sq ft where low maintenance, lightweight handling, and zero-emissions cordless mowing are the priority.
Consider alternatives if your yard exceeds 8,000 sq ft, includes significant slopes, or if you need a self-propelled drive to reduce pushing effort.
