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)
Steel Cutting Deck
Durable steel deck for long-term use
3-in-1 Discharge
Mulch, side discharge, and rear bag (59 of 364 mowers have all three)
Rear-Wheel Drive
Better traction on hills and slopes vs front-wheel drive
Why We Recommend It
- 01.
Wide 21-inch steel cutting deck covers more ground per pass than the 18-inch walk-behind average , fewer passes, less time mowing
- 02.
3-in-1 discharge system (mulching, side discharge, rear bag) available on only 59 of 364 mowers reviewed , exceptional versatility
- 03.
Rear-wheel drive self-propulsion delivers better hill traction than front-wheel drive models, reducing operator fatigue on slopes
- 04.
Push-button start with LED headlights , no pull cord frustration, mow earlier or later in the day
- 05.
No oil changes, spark plugs, or carburetor maintenance , the low-maintenance advantage of battery power with 3-year warranty coverage
Considerations
- 01.
35-minute runtime per battery charge may require mid-lawn battery swap for yards larger than ~1/3 acre (three batteries help offset this)
- 02.
At 43 lbs, it's heavier than lightweight push mowers , not the easiest to maneuver for users who prefer minimal physical effort
- 03.
Batteries are 24V units run in series to achieve 48V, meaning they're not interchangeable with standard 40V or 60V Greenworks platforms

Power & Performance
Running on a 48V system achieved by pairing two 24V 5.0Ah batteries in series, this Greenworks motor delivers power and torque comparable to mid-range gas mowers for typical suburban grass conditions. The brushless motor design extracts more efficiency from each charge cycle, making it effective on moderately thick, tall grass and weeds without the bogging common to underpowered battery mowers.
For standard Kentucky bluegrass, fescue, or Bermuda lawns kept at reasonable heights, this power level handles the job cleanly.
Cutting System
The 21-inch steel cutting deck provides a durable, wide cutting path that reduces the number of passes required compared to the 18-inch average for walk-behind mowers. Seven cutting height positions give fine-grained control over lawn height, and the 3-in-1 discharge system , mulching, side discharge, and rear bagging , is a standout feature found on fewer than 20% of comparable mowers.
Mulching mode returns nutrients to the lawn, while the rear bag option is ideal for cleanups or seasonal mowing where clipping removal is preferred.
Drive & Handling
Rear-wheel drive self-propulsion is a meaningful upgrade over front-wheel drive designs, particularly on inclines and slopes where rear traction keeps the mower moving forward without spinning out. At 43 lbs, it's a mid-weight machine , heavier than lightweight push models but manageable thanks to the self-propelled drive removing most of the physical effort.
The foldable handle collapses the mower into a compact footprint for garage or shed storage, an important consideration for users with limited space.
Battery / Fuel
Each of the three included 24V 5.0Ah batteries delivers approximately 35 minutes of runtime under typical mowing conditions. With two chargers included, you can keep one battery on charge while another is in use , a smart design choice that minimizes downtime for larger jobs.
Unlike gas engines, there's no fuel mixing, no oil maintenance schedule, and no carburetor to gum up over winter storage , simply charge the batteries before the season starts and the mower is ready to go.
Who Is This Mower For?
Ideal For
- ✓ Suburban homeowners with 1/4 to 1/2 acre flat-to-moderately-hilly yards who want zero-emissions mowing without sacrificing the wide 21-inch cut of a full-size mower
- ✓ Gas-to-electric switchers who want a complete yard tool bundle , the included trimmer and blower mean one purchase replaces three gas tools at once
- ✓ Low-maintenance users who are tired of oil changes, spark plugs, and pull-start frustrations , push-button start and battery power eliminate all of that
- ✓ Eco-conscious homeowners who want quieter, zero direct emissions operation and still need self-propelled drive for mild slopes
Not Ideal For
- ✕ Large property owners with 3/4 acre or more , the 35-minute runtime per battery may cause interruptions even with 3 batteries rotating
- ✕ Users with steep, demanding hillside terrain who need maximum torque and traction beyond what a rear-wheel drive battery mower can consistently deliver
- ✕ Existing Greenworks 40V or 60V platform users , the 24V batteries in this combo are not cross-compatible with other Greenworks voltage families
The Greenworks combo arrives largely pre-assembled with no significant build steps required , customers consistently report being able to unfold the handle, insert a battery, and start mowing within minutes of opening the box.
Charge all three batteries to full before your first mow to establish battery memory and get a baseline sense of your per-battery yard coverage
Attach the rear bag or confirm the mulch plug is seated before starting , the 3-in-1 system requires the correct accessory to be installed for optimal discharge
Greenworks covers this mower with a 3-year warranty, which is above average for battery-powered lawn mowers in this category. Verify full warranty terms including battery coverage directly with Greenworks, as battery warranty periods can differ from tool body coverage.
FAQ
How long do the batteries last on the Greenworks 48V mower?
Each of the three included 24V 5.0Ah batteries provides roughly 35 minutes of runtime under normal mowing conditions. With two chargers in the box, you can rotate batteries , charging one while the other runs , to extend your mowing session.
For yards under 1/3 acre, many users complete the entire yard on a single battery charge.
Is the Greenworks 48V mower self-propelled, and how well does it handle hills?
Yes, this is a rear-wheel drive self-propelled mower. Rear-wheel drive provides better traction on slopes and hills compared to front-wheel drive designs because the weight of the mower stays over the drive wheels.
It's adequate for moderate inclines, though very steep hillside terrain may push the limits of any battery-powered self-propelled mower.
Does the Greenworks 48V combo include a mulching bag?
Yes , the mower features a 3-in-1 discharge system supporting mulching, side discharge, and a rear collection bag. All three options are included with the mower, giving you full flexibility to mulch clippings back into the lawn, discharge to the side for fast cleanup, or bag for a pristine finished look.
Are the 24V batteries compatible with other Greenworks tools?
The batteries included with this combo are 24V units designed for Greenworks' 24V platform. They are not cross-compatible with Greenworks' 40V or 60V tool families.
If you already have Greenworks 40V or 60V tools, the batteries from those systems will not work in this mower , keep this in mind when evaluating total ecosystem value.
How loud is the Greenworks 48V battery lawn mower compared to gas?
Battery-powered mowers like this Greenworks model operate significantly quieter than gas mowers , typically in the 75-80 dB range versus 90-95 dB for comparable gas models. This makes it a solid choice for early morning or evening mowing without disturbing neighbors, a key benefit of zero-emissions electric operation that gas mowers simply can't match.
How much yard can the Greenworks 48V mower handle before needing a recharge?
With a 21-inch cutting deck and approximately 35 minutes per battery, most users with yards up to 1/3 acre can complete the job on a single charge. The three included batteries effectively extend your total capacity to over 100 minutes of runtime , enough to handle yards approaching 1/2 acre when rotating batteries with the two included chargers.
Bottom Line
The Greenworks 48V combo is one of the most compelling all-in-one battery lawn mower packages available , a wide 21-inch steel deck, rear-wheel drive self-propulsion, 3-in-1 discharge, and a full trimmer and blower kit make it exceptional value for suburban homeowners ready to go gas-free. The 35-minute runtime per battery is manageable given the three included batteries, but buyers with larger properties should weigh that limitation carefully.
For the target user, this mower delivers powerful, efficient, low-maintenance performance that genuinely pays for itself in eliminated fuel and maintenance investment.
Best for suburban homeowners with up to 1/2 acre wanting a complete, zero-emissions battery lawn mower combo with trimmer and blower included.
Consider alternatives if you have a large property over 1/2 acre, steep terrain demanding maximum torque, or an existing Greenworks 40V/60V battery platform you want to stay compatible with.
