WORX 20V 12-inch 3-in-1 Cordless String Trimmer, Edger & Mini Mower WG170.9 — Bare Tool, DNA2 Line

The WORX GT 20V WG170.9 is a lightweight, 3-in-1 cordless yard tool that converts between a string trimmer, in-line wheeled edger, and compact mini-mower for fast, professional-looking lawn edges and touch-ups.

This compact powerhouse combines agility, reach, and patented cutting line technology into a single bare-tool unit (battery and charger sold separately). At about 5.5 pounds with a battery attached and a motor spinning at 7,600 rpm, the GT is designed to handle routine trimming, precise edging, and small-area mowing without the bulk of separate devices. Its DNA2 double-helix line and on-board spool storage are built to keep you cutting longer with fewer interruptions.

How does the GT switch between trimmer, edger, and mini-mower?

Transitioning modes is tool-free and intuitive: reconfigure the head and wheel assembly to match the task. The unit’s modular design lets you move from vertical trimming to a wheeled in-line edge or a low-profile mini-mow in minutes, so one tool serves three common yard chores.

• Quick-change head and wheels for each mode
• Support wheels included for stable edging and mini-mower use
• Compact mini-mower profile for small clearings and touch-ups

What makes the cutting line more durable and easier to use?

The GT uses the patented DNA2 double-helix cutting line engineered to cut efficiently and resist breakage. An automatic command-feed system lets you advance fresh line with a button press, eliminating frequent stops to manually feed line.

• DNA2 double-helix line for lower drag and higher tensile strength
• On-board spool holder stores a spare spool for quick swaps
• Spools for Life program available—replacement spools shipped for shipping and processing

Will the GT be comfortable for different user heights and long jobs?

Yes — the GT features a telescoping shaft and multiple handle/head settings so taller and shorter users can find a comfortable working posture. At roughly 5.5 pounds (with battery) it’s light enough to use for extended periods without excessive fatigue.

• Telescoping shaft extends one foot beyond the previous model
• Seven handle positions and six rotating head angles for ergonomic control
• Lightweight design helps reduce user fatigue during longer sessions

What battery options and compatibility should I know about?

The GT is sold as a bare tool and uses WORX 20V batteries from the PowerShare family. That same 20V battery platform powers many WORX tools, so batteries and chargers can be shared across compatible products.

• Bare-tool model: battery and charger sold separately
• Compatible with WORX PowerShare 20V batteries for cross-tool use
• Works with over 75 WORX products across 20V, 40V, and 80V ranges (where adapters or platform compatibility apply)

Who is this for: The WORX GT WG170.9 is ideal for homeowners, renters, and small-property owners who want one versatile, lightweight tool to handle trimming, edging, and small-area mowing without juggling multiple machines. It fits users who value portability, interchangeable battery convenience, and quick line changes, but note that a 20V WORX battery and charger are required and sold separately.
