Detailed Description
Effortless, Powerful, and Gas-Free Lawn Care. The Greenworks cordless mower delivers professional-grade cutting power without the noise, fumes, or maintenance of gas mowers. Perfect for lawns up to 1/4 acre, it combines two 24V 5.0Ah lithium-ion batteries for 48V performance—giving you up to 45 minutes of runtime (varies by grass thickness).
Why You’ll Love It:
- Self-Propelled & Adjustable: The variable-speed rear-wheel drive tackles hills easily, while 7 cutting heights adapt to any lawn.
- 4-in-1 Flexibility: Choose mulching, rear bagging, side discharge, or turbo mode for heavy debris.
- Brushless Motor Tech: Around 30% quieter than comparable gas models, with more torque, longer life, and less vibration.
- Smart Battery System: The included batteries even feature USB ports for charging devices and are compatible with 200+ Greenworks tools.
- No More Gas Hassles: Instant electric start, no oil changes, and eco-friendly operation.
Performance and Runtime
Cutting Performance
The brushless electric motor gives strong, consistent torque. In my testing on medium-thick grass, the 21-inch brushless mower handled 2–3 inch grass without bogging down, and the turbo mode makes leaf cleanup practical. The 21" deck hits a sweet spot for medium yards—fast coverage with good maneuverability.
Battery & Charging
With two 5.0Ah batteries you can expect up to 45 minutes of run-time under ideal conditions. The dual port rapid charger brings both batteries back to full much faster than single-port chargers, and the batteries are compatible across many Greenworks tools — a real plus if you already own the brand.
Pros and Cons
Pros
- Quiet, powerful brushless motor—less maintenance and longer life.
- Dual 24V batteries combine to provide 48V performance.
- Self-propelled and variable speed—great for hills and larger yards.
- 4-in-1 deck for mulching, bagging, and side discharge.
- LED headlight for early morning or late evening mowing.
- Includes batteries and rapid charger—no need to buy separately.
Cons
- Runtime varies widely with grass height and terrain; very dense lawns may need a recharge.
- Heavier than push-only battery mowers due to batteries and self-propel system.
- Not ideal for very large properties (over 1/2 acre) unless you have spare batteries.
Who Should Buy This Product
If you’re searching for the best cordless self-propelled mower to buy for medium-size lawns, the Greenworks 48V lawn mower is a top pick. Choose this mower if you:
- Want a battery powered lawn mower with professional-level cutting and low maintenance.
- Own other Greenworks tools and want batteries that cross-compatibility matters.
- Need a quiet brushless 21-inch battery mower for medium yards.
- Prefer a low maintenance brushless cordless lawn mower with practical runtime and fast charging.
Comparison with Similar Products
Compared to other 21" battery mowers, the Greenworks stands out for its included dual 5Ah batteries and dual-port rapid charger. Some competitors sell the mower bare (no battery), which increases upfront cost if you need batteries. If your priority is a 48V mower with two 5.0Ah batteries and dual port rapid charger, this kit offers better immediate value.
For hilly terrain, the self-propelled drive and variable speed give it an advantage over non-propelled battery models. If you need the absolute longest runtime though, look at higher-voltage or larger battery platforms—but you’ll likely pay more.
