The Greenworks 48V (24V x 2) Cordless Lawn Care Combo Kit bundles a 21″ brushless self-propelled mower, a 12″ string trimmer, and a 320 CFM blower into one package — along with two 5.0Ah batteries and a dual-port charger — all for $699 and backed by a 3-year warranty. With a 4.0-star rating across 272 reviews, it has enough buyer feedback to take seriously. For a hands-on look at a higher-voltage alternative, see our Greenworks 80V lawn care kit review.

Before we dive in, our team also has a full breakdown of the Greenworks 80V 42-inch riding mower if your property outgrows a walk-behind setup.

Quick Verdict

Verdict: A strong-value midrange cordless combo — buy it if you want a complete 3-tool system with real batteries included.

The brushless self-propelled mower is the star here, and two 5.0Ah batteries put this kit ahead of most budget bundles. The trade-off: the trimmer and blower use brushed motors, so they lack the raw power and longevity of premium-tier tools. At $699 with a 3-year warranty, it’s an easy recommendation for small-to-mid suburban lawns — but serious trimming work or large properties should look at the 80V lineup.

What’s in the Kit

The 21″ Brushless Self-Propelled Mower

The mower is the centerpiece and the best-engineered tool in the box. Its brushless motor wastes less energy than brushed designs, which translates to better runtime per battery and fewer maintenance headaches over the ownership period. The 21-inch steel deck hits the sweet spot for suburban lawns — wide enough to cut down on passes, narrow enough to navigate tighter yards and gates.

The self-propelled drive is the single biggest quality-of-life feature here. If your yard has slopes, uneven ground, or long runs of grass, it turns mowing from a workout into a walk. Add the 3-in-1 cutting system (mulching, rear bagging, side discharge) and 7-position height adjustment, and you have a mower that adapts to thick spring growth, fall leaf management, and everything in between. The vertical storage design is a genuinely useful bonus for garages where floor space is tight.

The 12″ String Trimmer

The trimmer uses a brushed motor with a 0.065″ line and an auto-feed head. It’s well-suited to routine edging and trimming around beds, fences, and walkways. The auto-feed system spares you the bump-and-advance ritual, though 0.065″ line will struggle with thick woody weeds — that’s normal at this class, not a defect. Just don’t expect it to match the torque of a premium brushless trimmer.

The 320 CFM Blower

Rated at 320 CFM and 90 MPH with a variable-speed dial, the blower handles leaves, grass clippings on the driveway, and light debris comfortably. Expect up to 20 minutes of runtime per charge, which is enough for most driveway-and-patio cleanup sessions on a typical lot. Like the trimmer, it’s a brushed motor — fine for seasonal cleanup, but heavy-duty leaf clearing on large properties will expose its limits.

The Battery System: The Real Value Play

The battery package is one of the strongest parts of the value equation. Two 5.0Ah batteries plus a 4A dual-port charger means you can mow on one pack while the other charges — and rotate batteries between the trimmer and blower without waiting. Many competing bundles cheap out with a single smaller battery; this kit doesn’t.

What this means for you is… this combo sits in a practical middle ground: stronger than most budget kits thanks to the brushless mower and dual 5.0Ah batteries, but not as aggressive or refined as top-tier systems where all three tools would be brushless.

Pros & Cons

✅ Pros

  • Brushless mower motor improves efficiency — wastes less energy, extends runtime, and reduces long-term maintenance.
  • Two 5.0Ah batteries add real utility — rotate between tools and keep mowing while one charges; most budget bundles include less.
  • Self-propelled drive reduces physical effort — a major upgrade on slopes and long lawns, and a key reason to pick this over push-mower combos.
  • 21-inch steel deck covers ground efficiently — the right width for suburban lots, with durable steel construction.
  • 3-in-1 versatility is genuinely useful — mulch, rear bag, or side discharge depending on season and conditions.
  • Complete 3-tool system out of the box — mower, trimmer, blower, batteries, and charger means nothing else to buy to start.
  • 3-year warranty — solid coverage for a multi-tool package.

❌ Cons

  • Trimmer and blower use brushed motors — less power and shorter motor life than premium brushless equivalents.
  • Blower runtime tops out around 20 minutes — larger cleanup jobs will need a battery swap or recharge.
  • 0.065″ trimmer line limits heavy-duty use — thick weeds and brush will demand patience.
  • 48V (24V × 2) platform has a power ceiling — if you later upgrade, the 80V lineup offers more headroom.
  • $699 requires budget justification — cheaper single-tool entry points exist if you don’t need all three tools at once.

Who Should Buy This Kit?

Buy the Greenworks 48V combo if: you have a small-to-mid suburban lawn (roughly up to half an acre), you’re tired of gas maintenance, and you want a complete cordless system in one purchase. The self-propelled mower alone justifies much of the price, and the two 5.0Ah batteries make the whole ecosystem practical.

Skip it if: you need serious trimming power, you’re clearing large or heavily wooded lots, or you’d rather invest step-by-step in a higher-voltage platform like the Greenworks 80V system.

Frequently Asked Questions

Q: How long will the batteries run the mower?

With two 5.0Ah batteries, you can expect enough combined runtime to handle most suburban lawns up to about half an acre on a single mowing session. The dual-port charger lets you rotate packs, so a mid-mow battery swap costs you only a few minutes of downtime.

Q: Can I use the 48V (24V × 2) batteries with other Greenworks tools?

Yes — the two 5.0Ah batteries work across Greenworks’ 24V tool lineup, and the kit’s dual-battery architecture powers the 48V mower. Check compatibility with any specific 24V tool before buying, but this is one of the platform’s biggest advantages: batteries you buy keep working as your collection grows.
