The Greenworks 40V 12" Cordless String Trimmer is a lightweight, battery-powered trimmer with a 12-inch dual-line cutting system, auto-feed line and variable speed for efficient edging and trimming.

Designed for homeowners who want a fuss-free, cord-free trimming solution, this Greenworks trimmer pairs a compact 40V motor with a 0.065" dual-line head and an included 2.0 Ah battery and charger. It removes the hassle of gas maintenance and extension cords while delivering consistent cuts around sidewalks, flower beds, fences and driveways. The tool’s auto-feed line system and variable-speed trigger let you focus on the job instead of constant adjustments.

How does the 12" dual-line cutting system perform on typical yard tasks?

The 12-inch cutting path with dual 0.065" lines provides clean, even cutting for grass and light weeds without excessive passes. It balances coverage and maneuverability, making it ideal for trimming around obstacles and reaching narrow spots where a mower can’t go.

• 12" cutting swath for efficient passes around lawns and edges
• Dual 0.065" lines for consistent, even cuts
• Suitable for grass, light weeds and edging near hard surfaces

What convenience features reduce downtime and user fatigue?

The auto-feed line system advances cutting line during operation so you don’t have to stop to bump or manually feed line. The lightweight, ergonomic design and well-balanced shaft minimize strain for longer trimming sessions, and the variable-speed trigger helps tailor power to the task, conserving battery when full power isn’t needed.

• Auto-feed line system for uninterrupted trimming
• Variable-speed trigger for precise control and battery conservation
• Ergonomic, lightweight build to lower user fatigue

How long will the included 2.0 Ah battery last and how fast does it recharge?

Runtime depends on speed setting and task density: light edging on low speed can run longer, while heavy trimming on high speed uses more power. The included 2.0 Ah battery provides enough charge for typical small- to medium-sized yards, and the packaged charger returns the battery to full charge without needing separate purchases.

• 2.0 Ah battery suited for routine yard maintenance
• Charger included to restore charge between sessions
• Runtime varies with speed and vegetation density
