WORX Cordless 20V 12-inch String Trimmer & Edger WG163.9 — Telescoping Shaft, One‑Button Command Feed

The WORX WG163.9 is a lightweight 20V cordless 2-in-1 string trimmer that converts to an edger in seconds and uses a one-button Command Feed for instant line extension.

This compact battery-powered trimmer combines a 12-inch cutting swath with a telescoping shaft, multi-position handle and a 100% single-line feed system so you can trim and edge without frequent stops. At just 4.63 pounds, it balances cutting performance with easy maneuverability, making it useful for small to medium yards, borders, and tight spaces where corded tools or heavier gas models are impractical.

How does the Command Feed make trimming faster?

The Command Feed replaces bump-head systems with a push-button that advances trimming line instantly while you work. That avoids flipping or tapping the tool, keeping your workflow steady and reducing interruptions.

• Push-button instant line extension—no bumping required
• Single-line spool for simpler reloading and consistent feed
• Extended run time from the 20V max lithium battery

Can this unit really switch to an edger, and is it stable?

The WG163.9 converts to an edger by rotating and locking the cutting head; dual-position inline wheels guide straight edging along sidewalks and flower beds. A flower-space guard also doubles as an edger guide to protect plants while keeping a clean line.

• Pull-and-turn head locks into edger mode quickly
• Rubberized twin wheels stabilize edging and produce uniform results
• Flower-space guard shields vegetation and acts as an edging guide

What comfort and control features reduce fatigue?

This trimmer is built for longer sessions: the telescoping shaft and a front auxiliary handle with seven locking positions adapt to different users and postures. A quick-release trigger lever and a 90° tilting shaft let you reach slopes and awkward angles with less strain.

• Telescopic shaft for height adjustment and ergonomic reach
• Front handle with 7 positions for personalized balance and grip
• 90° tilt for sloped areas and hard-to-reach spots

How much yard can I cover on a single charge?

Run time depends on battery capacity and cutting conditions, but the 20V max lithium platform offers longer operation than old NiCd packs. The efficient single-line feed and 12-inch cutting diameter reduce wasted passes so you cover more area in fewer battery cycles.

• 12-inch cutting swath trims more grass per pass
• Lightweight 4.63 lb design reduces user fatigue for longer sessions
• Efficient line feed and motor use battery power effectively

Who is this for? The WORX WG163.9 suits homeowners who want cordless convenience and quick transitions between trimming and edging without the weight or noise of gas tools. It’s ideal for small-to-medium lawns, tight borders, patios, and gardeners who value maneuverability, ease of use and straightforward maintenance. If you prefer a compact, battery-driven tool with simple controls and practical comfort features, this 2-in-1 trimmer/edger delivers professional-looking edges and tidy grass lines with less effort.
