What Sets It Apart
Key specification highlights based on our analysis.
21.0-Inch Cutting Deck
Wide cutting path reduces passes (walk-behind avg: 18.0 in)
3-in-1 Discharge
Mulch, side discharge, and rear bag (59 of 364 mowers have all three)
60V Battery System
High-voltage platform for more power (database avg: 38.1V)
Rear-Wheel Drive
Better traction on hills and slopes vs front-wheel drive
Considerations
Polymer Cutting Deck
Lightweight but less durable than steel; won't rust
Why We Recommend It
- 01.
High-voltage 60V brushless motor outperforms lower-voltage cordless competitors and handles tall, dense grass that would bog down 40V systems
- 02.
21-inch cutting deck is 3 inches wider than the 18-inch walk-behind average, meaningfully reducing the number of passes on medium yards
- 03.
Rear-wheel drive delivers better hill traction than front-wheel-drive models, making it adequate for gentle slopes
- 04.
3-in-1 discharge (mulch, side discharge, rear bag) offers flexibility only 59 of 364 mowers in class provide
- 05.
Zero maintenance compared to gas mowers , no oil changes, spark plugs, air filters, or fuel stabilizer required
Considerations
- 01.
Polymer cutting deck is lighter and rust-proof but less impact-resistant than steel decks if you regularly hit rocks or roots
- 02.
45-minute runtime per battery pair may fall short on larger yards over half an acre, requiring a mid-mow recharge
- 03.
At 65 lbs, it's heavier than many cordless competitors, which can be noticeable on longer mowing sessions despite the self-propelled assist

Power & Performance
The 60V brushless motor sits well above the 38.1V platform average found across the cordless mower database, translating to more torque under load when cutting high grass or pushing through thick, wet conditions. Brushless motors also run cooler and more efficiently than brushed alternatives, which helps preserve battery capacity over longer mowing sessions.
Customers consistently report the mower handles overgrown and high grass with ease , a common weak point for lower-voltage cordless models.
Cutting System
The 21-inch rotary deck is made from polymer, which keeps weight down and eliminates rust concerns but is less forgiving of impacts than steel. Cutting height is adjustable to accommodate different grass types and seasonal needs.
The 3-in-1 discharge system , mulching, side discharge, and rear bagging , gives homeowners the flexibility to fertilize naturally with clippings or collect them cleanly, and this combination is found in fewer than 20% of comparable walk-behind mowers.
Drive & Handling
Rear-wheel drive is the preferred drive configuration for slopes and uneven terrain because the weight of the mower is over the drive wheels, improving traction when the front wheels lift slightly on inclines. The variable speed control lets you match the mower's pace to your natural walking speed and terrain, reducing the tendency to fight the mower or get pulled along.
At 65 lbs it's on the heavier end for cordless, but the self-propelled system offsets most of that on flat and moderate slopes.
Battery / Fuel
Two 60V 4.0Ah batteries are included alongside a rapid dual-port charger that can charge both simultaneously, minimizing downtime between uses. Runtime is rated up to 45 minutes with both batteries, which is competitive for high-voltage cordless mowers and sufficient for most medium-sized yards in a single session.
Unlike gas mowers, there's no seasonal maintenance , no fuel stabilizer, no carburetor cleaning, and no cold-start issues , making spring startup as simple as charging the batteries.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with medium yards (1/4 to 1/2 acre) who want gas-level cutting power without fuel, oil changes, or pull-cord frustrations
- ✓ Eco-conscious users switching away from gas mowers , zero direct emissions, significantly quieter operation, and compatible with Greenworks' 75+ tool battery ecosystem
- ✓ Anyone mowing on gentle slopes or uneven terrain, where rear-wheel drive traction and variable speed control provide a clear advantage over front-wheel or push models
- ✓ Early-morning or evening mowers who will appreciate the LED headlights and quieter brushless motor in noise-sensitive neighborhoods
Not Ideal For
- ✕ Large property owners with half an acre or more , 45-minute runtime may require stopping to recharge mid-lawn, disrupting workflow
- ✕ Users with steep hills or heavily terraced yards where a more powerful self-propelled drive system or even a riding mower would be safer and more effective
- ✕ entry-level-first buyers who already own a different battery platform, since the 60V system won't cross-charge with other brands' tools
Assembly is required out of the box but is straightforward for most users , typically involving attaching the handle, installing the grass bag, and charging the batteries before first use. The deck height adjustment mechanism has been specifically noted by customers as easy to operate.
Charge both batteries fully before the first mow so you can confirm total runtime on your specific yard size
Use the dual-port rapid charger to charge both batteries simultaneously , it significantly cuts total charge time compared to charging them sequentially
Greenworks covers this mower with a 4-year warranty on both the tool and the batteries , one of the strongest warranty packages in the cordless mower category, where 2-year battery coverage is far more common. Always register the product with Greenworks after purchase to ensure full warranty activation.
FAQ
How long does the battery last on the Greenworks 60V 21" mower?
Greenworks rates the two included 4.0Ah batteries at up to 45 minutes of combined runtime. Real-world duration depends on grass height and density , thick, high grass draws more power and will shorten that window.
For most medium yards under half an acre, one full charge is typically enough to finish the job.
Is this mower good for hills and slopes?
The rear-wheel drive system provides better traction on slopes than front-wheel-drive models because the drive wheels sit beneath the heavier rear of the mower. It's rated adequate for gentle to moderate slopes, and the variable speed control lets you set a pace that feels stable on inclines.
For steep or heavily terraced terrain, a higher-torque model would be more appropriate.
Does the Greenworks 60V mower work with other Greenworks tools?
Yes , the 60V batteries are compatible with Greenworks' 75+ tool lineup including blowers, string trimmers, chainsaws, and snow blowers. This makes it a strong anchor purchase if you're building out a battery-powered yard care ecosystem, since you can share batteries across tools.
How does this compare to a gas mower for cutting power?
The 60V brushless motor delivers performance that rivals entry-level to mid-range gas mowers for typical residential grass cutting. It handles high grass well according to customer feedback, though an exceptionally overgrown yard may require a slower pace.
The key trade-off versus gas mowers is runtime versus refueling , instead of a quick tank fill, you're working within a 45-minute battery window.
What are the cutting height options on this mower?
The Greenworks 60V features adjustable cutting height to suit different grass types and seasonal cutting preferences. The single-lever or wheel-adjustment system (verified easy to use by customers) lets you quickly raise or lower the 21-inch deck without tools.
Check the product listing for the specific height range in inches for your grass type needs.
Is the Greenworks 60V mower hard to maintain?
Maintenance is minimal compared to gas mowers , there's no engine oil, spark plugs, air filter, fuel line, or carburetor to service. Routine care involves keeping the blade sharp, cleaning grass clippings from the underside of the deck after use, and storing batteries in a cool, dry location during off-season.
This low-maintenance profile is one of the top reasons homeowners switch from gas to cordless electric.
Bottom Line
The Greenworks 60V 21" Self-Propelled delivers a compelling combination of high-voltage cutting power, rear-wheel drive traction, and zero-maintenance convenience that makes it a strong pick for suburban homeowners ready to leave gas mowers behind. The inclusion of two batteries, a dual-port rapid charger, and a 4-year warranty makes the value case even stronger.
If your yard is over half an acre or heavily sloped, the 45-minute runtime or the drive system may leave you wanting more , but for the majority of medium-yard homeowners, this mower is hard to beat in its class.
Best for medium suburban yards up to 1/2 acre where homeowners want gas-level power, rear-wheel drive traction, and zero ongoing maintenance
Consider alternatives if your property exceeds half an acre, features steep slopes, or you need more than 45 minutes of continuous runtime per session
