Greenworks 40V 16in Brushless Cordless String Trimmer - Gen 2

In this review of the Greenworks 40V 16in Brushless Cordless String Trimmer (Gen 2) the bottom line is simple: this is a practical, low-maintenance trimmer for homeowners who want near gas-level power without engines, fumes, or routine tune-ups. It shines for routine trimming and edging around sidewalks, driveways, flower beds and fence lines, and the included 4.0Ah battery and charger make it ready to use out of the box. The brushless motor delivers more power and longer run-times than brushed models, and the attachment-capable design adds long-term versatility for those who want a single platform for multiple yard tasks.

Key Features

• 16in cutting swath: The 16in head is wide enough to finish most small-to-medium lawns quickly while still allowing precise edging along beds and paths.
• Brushless motor: The brushless design provides stronger performance, improved efficiency and extended motor life compared with brushed motors.
• Attachment capable: Compatible with multiple Greenworks PAC attachments so the same powerhead can become an edger, hedge trimmer, polesaw, cultivator or blower.
• Compact and lightweight: At roughly 25% lighter than comparable gas models, it is easier to maneuver for longer sessions with less fatigue.
• Two-speed modes: Variable speed trigger plus two selectable speeds let you balance runtime and cutting force depending on grass conditions.
• Maintenance free: No gas or oil to mix, instant starts and quiet operation simplify ownership and storage.

Who It's For

The Greenworks 40V 16in Brushless Trimmer is best for homeowners with small to medium yards (up to about a half acre with the broader platform batteries) who want cordless convenience and the power to handle thicker grass and roots without gas maintenance. It also suits buyers who value a single battery platform that powers multiple outdoor tools and who may add attachments later for extra versatility.

It may be less suited for large-acreage properties where continuous heavy-duty work is required or for users who need commercial-grade, full-shaft gas power for sustained, professional workloads. Buyers who prioritize ultra-heavy professional use should evaluate commercial gas trimmers instead.

Pros & Cons

Pros

• Brushless motor delivers strong cutting performance and longer runtime compared with brushed alternatives.
• Included 4.0Ah battery and charger get the tool in use immediately and provide good battery life for typical residential trimming.
• Attachment-capable system gives future expandability to edger, hedge, polesaw, cultivator and blower functions.

Cons

• Some users report mixed durability experiences, with a minority encountering early failures; careful handling and proper assembly help mitigate this risk.
• For very large properties or continuous commercial use the cordless platform may require multiple batteries and charging cycles.

Our Verdict

Its combination of a brushless motor, included 4.0Ah battery and attachment capability makes it good value for seasonal yard care, while users with very large or commercial workloads should consider more heavy-duty options.
