Greenworks 24V 12" Cordless String Trimmer & Edger — 4.0Ah Battery, Brush Cutter, 20 Blades

The Greenworks 24V 12" Cordless String Trimmer & Edger is a lightweight, tool-free 2-in-1 yard tool that converts between trimming and edging in seconds and runs on a 4.0Ah rechargeable battery.

This compact battery-powered trimmer blends easy handling with enough cutting power to maintain small to medium yards, tackle thick weeds with the included brush-cutter attachment, and edge sidewalks without bending or fuss. Its telescoping aluminum shaft adapts to users from 4'8" to 6'5", and the 4.0Ah battery delivers up to about 45 minutes of runtime while working with Greenworks' 24V platform so you can share batteries across compatible tools.

How quickly does it switch between trimming and edging?

Switching modes is designed to be fast and tool-free: press a single button to flip between trimming and edging functions so you can move from lawn edges to wide swaths of weeds without stopping to reconfigure the tool.

• One-button mode change—no tools required.
• 12" cutting width for efficient passes across grass and weeds.
• Brush cutter attachment included for denser vegetation.

Can the trimmer handle heavy growth and brush?

Yes—this model comes with a brush cutter attachment and 20 reinforced plastic replacement blades, which extend its capability beyond light grass to tackle overgrown beds and thicker weeds while minimizing nicking on nearby plants.

• Brush cutter configuration chops through thick weeds and small shrubs.
• 20 reinforced blades included plus a tool-free replacement kit.
• .065" single-line auto-feed head reduces jams and downtime.

How comfortable is it to use for different heights and long sessions?

The telescoping aluminum shaft adjusts to fit users from 4'8" up to 6'5", which helps maintain an ergonomic posture and reduces bending. The unit is significantly lighter than standard gas trimmers, easing fatigue for extended yard work.

• Telescoping shaft customizes length for better posture.
• 65% lighter than comparable gas models for easier handling.
• Push-button start eliminates pull cords—simple and quick.

What does the battery support and how long will it run?

The included 4.0Ah battery is rated to power up to roughly 45 minutes of runtime depending on conditions, and the rapid charger gets it back to work quickly. It also belongs to Greenworks' 24V battery family, so the same battery fits 125+ compatible tools for convenient sharing.

• 4.0Ah battery offers about 45 minutes typical runtime.
• Fast charger included to minimize downtime between jobs.
• Compatible across Greenworks 24V tools to expand your cordless toolkit.

Who this tool is for: homeowners with small to medium yards, renters who need quiet, low-maintenance lawn care, seniors and teens who prefer lighter tools, and anyone building out a cordless Greenworks 24V ecosystem. It’s ideal if you want a simple, convertible trimmer/edger that balances portability, battery runtime, and enough cutting muscle for tougher patches without gasoline or complex maintenance.
