Complete combo kit value: mower + 12" string trimmer + 320CFM blower plus two 5.0Ah batteries and a 4A dual-port charger , no separate tool purchases needed
- 02.
Brushless self-propelled rear-wheel drive handles inclines and uneven terrain with better traction than front-wheel drive systems
- 03.

- 04.
Zero direct emissions, push-button start, and no oil changes or spark plug maintenance , far lower upkeep than gas alternatives
- 05.
Industry-leading 3-year warranty covers every component in the kit including batteries and charger
Considerations
- 01.
Battery runtime is mixed in practice , two 5.0Ah batteries may not complete larger medium yards in a single charge cycle depending on grass conditions
- 02.
At 78.3 lbs, the mower is on the heavier side for a battery-powered unit, which can affect maneuverability in tight spaces despite the self-propelled feature
- 03.
20.5" cutting deck is slightly narrower than standard 21" gas mowers, meaning slightly more passes on wider open areas

Power & Performance
The 48V brushless motor (running on two 24V batteries in series) delivers efficient, sustained power well-suited for maintained lawns with regular grass heights. Brushless technology reduces friction and heat, translating to longer runtime per charge, a longer motor lifespan, and quieter operation compared to brushed alternatives.
For thick or neglected grass, performance may require multiple passes, but for weekly-maintained medium yards, output is consistently strong.
Cutting System
The 20.5" composite rotary deck strikes a balance between maneuverability and coverage speed, and composite construction resists corrosion better than steel in wet or humid conditions. The full 3-in-1 discharge system , mulching, side discharge, and rear bag , is a standout Mower Feature found on fewer than 1 in 5 mowers in this category, giving users full flexibility depending on clipping volume, season, and lawn health goals.
Cutting height adjustment range allows adaptation to different grass types and seasonal needs.
Drive & Handling
The rear-wheel drive self-propelled system is a meaningful upgrade over front-wheel drive, providing better traction on hills and slopes where the mower's weight shifts to the rear during operation. At 78.3 lbs, the mower is moderately heavy for a battery unit, but the self-propelled drive largely compensates for this on flat and gently sloped terrain.
Handle design and general maneuverability receive positive marks in customer feedback, with users noting ease of use in backyards with typical obstacle layouts.
Battery / Fuel
The combo kit ships with two 5.0Ah 24V batteries (48V combined) and a 4A dual-port charger that can charge both simultaneously, minimizing downtime between the mower and the string trimmer or blower. Runtime is adequate for most medium-sized yards in a single charge, though customer feedback is mixed , heavy grass or high self-propel speeds will drain batteries faster.
The dual-port charger is a practical inclusion in the storage design, and since the same batteries power all three tools, swapping between yard tasks is seamless.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with medium-sized yards (up to ~1/2 acre) who want a single-brand, battery-powered ecosystem to handle mowing, trimming, and blowing in one purchase
- ✓ Eco-conscious users seeking zero direct emissions and quieter operation compared to gas , the 48V brushless platform delivers on both
- ✓ Homeowners with moderately hilly or sloped terrain who need rear-wheel drive traction without the hassle of gas engine maintenance
- ✓ First-time lawn equipment buyers who want a complete, low-maintenance setup with a strong 3-year warranty covering every piece of the kit
Not Ideal For
- ✕ Owners of large properties (over 1/2 acre) who need extended uninterrupted runtime , two batteries may require recharging mid-session on bigger lots
- ✕ Users with very thick, overgrown, or wet grass who need peak sustained power , a gas-powered mower will outperform battery in the most demanding cutting conditions
- ✕ Those who already own Greenworks or other brand 48V batteries and don't need the bundled batteries, as the combo kit tier is built around the full package
Customers consistently report that assembly is straightforward and quick, with the mower ready to use in under 30 minutes out of the box. The battery-powered platform eliminates any fuel mixing or priming steps, making initial setup simpler than comparable gas models.
Charge both batteries fully before first use using the included 4A dual-port charger , the dual-port design means both are ready at the same time

FAQ
How long does the battery last on the Greenworks 48V mower?
With two 5.0Ah batteries, most users report enough runtime to cover a medium-sized yard (up to roughly 1/3 to 1/2 acre) in a single session under normal conditions. Heavy, wet, or tall grass will reduce runtime, and using the self-propelled drive at higher speeds draws more power.
The included dual-port charger recharges both batteries simultaneously to minimize downtime.
Does this Greenworks combo kit include everything I need, or do I need to buy batteries separately?
The combo kit includes everything out of the box: the 21" self-propelled mower, 12" string trimmer, 320CFM blower, two 5.0Ah batteries, and a 4A dual-port charger. No additional battery purchases are needed to get started, which is a key part of the value proposition of this bundle.
Is the Greenworks 48V mower good for hills?
Yes , the rear-wheel drive self-propelled system is specifically better suited for hills and slopes than front-wheel drive designs, because the weight of the mower shifts toward the rear wheels on inclines, maintaining traction where it's needed. Customer feedback confirms the self-propelled feature performs well on moderate slopes, though very steep terrain would benefit from a more purpose-built mower.
What is the cutting width of this Greenworks mower?
The cutting deck is 20.5 inches wide with a composite construction that resists rust and corrosion. It supports 3-in-1 discharge , mulching, side discharge, and rear bagging , giving you flexibility based on your lawn conditions and the season.
How does the Greenworks 48V compare to a gas mower for maintenance?
Maintenance is significantly lower with this battery-powered mower , there are no oil changes, spark plug replacements, air filter cleanings, or fuel system upkeep. Operation is push-button start with no pull cord.
Ongoing maintenance is essentially limited to blade sharpening and keeping the deck clean, making it a much simpler long-term ownership experience.
Can the batteries from the mower be used with the string trimmer and blower in this combo?
Yes , all three tools in this combo kit share the same 24V/48V Greenworks battery platform, so you can swap the 5.0Ah batteries between the mower, 12" string trimmer, and 320CFM blower freely. This interchangeable battery system is one of the core advantages of the combo kit, reducing cost and storage clutter compared to buying separate battery sets.
Bottom Line
The Greenworks 48V Combo Kit is the right choice for medium-yard homeowners who want a complete, low-maintenance battery-powered outdoor toolkit in a single purchase. The brushless self-propelled mower holds its own against gas competition for regular maintenance mowing, and the included string trimmer and blower with shared batteries make this a standout value.
Those with very large properties or particularly demanding cutting conditions will likely need to look at higher-capacity gas or commercial-grade options.
Best for medium-yard homeowners wanting a complete zero-emissions combo kit , mower, trimmer, and blower , with no extra battery purchases needed.
Consider alternatives if you have a large property over 1/2 acre, frequently deal with thick or overgrown grass, or need maximum sustained cutting power in challenging conditions.
