Key Features of Greenworks 48V 21″ Brushless

Self-Propelled Lawn Mower with 21-Inch Steel Deck

The mower features a durable 21-inch steel deck that handles most standard yard sizes with ease. Its self-propelled design makes mowing less strenuous, especially on uneven terrain or larger lawns. The 48V (24V x 2) power setup ensures ample torque, allowing the mower to cut through thick grass efficiently. It offers a 3-in-1 system—mulching, rear bagging, or side discharge—giving you versatile options based on your yard’s needs.

With seven adjustable height settings, you can customize the cutting height from a low of about 1.5 inches to a taller 3.75 inches, making it suitable for various grass types and conditions. Its vertical storage feature is a bonus for those tight on space, allowing the mower to stand upright when not in use.

Overall, this mower is designed for ease, efficiency, and space-saving storage, making yard work more manageable.

12-Inch Brushless String Trimmer

The included string trimmer boasts a 12-inch cutting path, ideal for edging, trimming around flower beds, and clearing hard-to-reach spots. Its brushless motor ensures smooth operation, reduced noise, and longer lifespan. The 0.065-inch auto-feed line simplifies line management, so you don’t have to constantly stop to adjust or replace line.

Lightweight and ergonomic, the trimmer reduces fatigue during extended use. Its compatibility with the same 48V batteries means you can swap power sources seamlessly between tools, enhancing convenience and reducing the need for multiple batteries.

320 CFM Blower with Variable Speed

Powering the blower is a brushed motor generating up to 320 CFM at 90 MPH—more than enough to clear leaves, grass clippings, and debris from driveways and lawns. It’s lightweight and features a variable speed dial, giving you control over airflow intensity. With approximately 20 minutes of runtime per battery charge, it’s perfect for quick cleanup tasks or small to medium-sized yards.

Its ergonomic design and lightweight build make it easy to maneuver, preventing fatigue during longer cleanup sessions.

Battery and Charger: 2 x 5.0Ah Batteries + Dual Port Charger

The kit includes two 5.0Ah batteries, providing extended runtime for all three tools. The dual-port charger allows you to recharge both batteries simultaneously, saving time and keeping your yard work flowing smoothly. Each component carries a 3-year warranty, giving peace of mind regarding durability and long-term use.

This setup ensures you always have a charged battery ready to go, minimizing downtime during yard maintenance.

The unified battery system simplifies operation, and the 3-year warranties across all items add confidence in their longevity and performance.

How Does Greenworks 48V 21″ Brushless Perform?

Handling Overgrown Grass

In my experience testing the mower, I found it handled overgrown grass surprisingly well. Even when grass was taller than the deck in some spots, the self-propelled feature and powerful brushless motor kept things moving smoothly. It’s not a heavy-duty commercial mower, but for typical residential lawns, it performs admirably. Expect to make a few passes on very thick or tall grass, but overall, it manages the task nicely.

Trimming and Edging with the String Trimmer

The string trimmer is lightweight and easy to control. I used it around flower beds and along fences, and it cut through dense weeds and wild grass without issue. The auto-feed line prevented interruptions, and the 12-inch cutting width made quick work of trimming tasks. It’s perfect for maintaining neat edges without the hassle of dealing with gas fumes or cords.

Clearing Debris with the Blower

The blower’s 320 CFM airflow and variable speed control provided excellent debris clearance. I used it on dry leaves and light debris, and it handled the job effortlessly. Although runtime is about 20 minutes per battery, it’s enough for quick cleanups, and swapping batteries is quick thanks to the dual charger. Its lightweight design made maneuvering comfortable, even during extended sessions.

Battery Performance and Runtime

The two 5.0Ah batteries provided ample power for all tools, with minimal performance drop-off during use. I was able to mow, trim, and blow in a single session without running out of juice. The quick-charging feature meant I could recharge batteries in about 1-2 hours, so I always had fresh power ready.

What Customers Are Saying About Greenworks 48V 21″ Brushless

Customer Review: “First use review. Used with a high-quality 15A power cable. Grass taller than the mower in some places. At the end of the day, it did the job well, and I have to admit I was expecting to be mildly disappointed, but I wasn’t. So I hit issues I would hit with any mower when the grass is this overgrown, but overall it handled it better than I thought.” – ★★★★☆

Customer Review: “I worked in automotive for 13 years, and really didn’t want to deal with a gas mower: fuel, 2-stroke/engine oil, carb, spark plug, leaks, pull-start, choke, prime, exhaust, heat, smelling up the garage, so much stuff! My reel mower can’t keep up with the grass in the summer, and string trimming the Greenworks 48V 21″ Brushless set made yard work so much easier.” – ★★★★☆
