WORX 3 in 1 Cordless String Trimmer/Lawn Edger/Mini Mower, 13" Electric Weed Wacker with Command Feed, 20V Weed Eater with Brushless Motor, 4.0 Ah Battery & Charger Included, WG173

What It Is

This is a complete WORX WG173 string trimmer kit—not a standalone battery or charger. It includes a 13-inch brushless 20V trimmer that converts to an edger and mini mower, with a 4.0 Ah battery and charger. Ideal for small to medium lawns, light trimming, and edging along walkways and fences.

Fitment & Compatibility

• Model check: This is the WG173 model itself, not a battery or charger accessory. It fits no other WORX trimmer—the battery is compatible with all WORX 20V Power Share tools, but the trimmer head and attachments are specific to this model.
• Deck size: 13-inch cutting width. Not for large lawns—expect 30–45 minutes of runtime on the included 4.0 Ah battery.
• OEM vs aftermarket: This is OEM WORX. Aftermarket batteries (non-WORX) may fit but risk poor performance or voiding warranty.
• Measurements: Trimmer head uses 0.065-inch line; spool is pre-wound. No special adapter needed for edger or mower conversion.

Key Things to Know

• Installation difficulty: Very easy—no tools required. The three-in-one conversion (trimmer, edger, mini mower) is tool-free with a simple twist-lock mechanism.
• Quality: Brushless motor is quieter and more efficient than brushed, but the plastic housing feels light. The 4.0 Ah battery delivers solid runtime for small yards but won’t handle heavy weeds.
• Common gotcha: The Command Feed bump head works only when the line is under 12 inches; it can jam if you bump too hard or run thick string. Use 0.065-inch line only—thicker will clog.
• Battery note: The included charger is a standard 20V fast charger (1.5A). It takes about 2.5 hours to fully charge a depleted 4.0 Ah battery.

Should You Buy It

Buy this if you have a small to medium lawn (under ¼ acre) and want a single tool that trims, edges, and mows tight spots. It’s lightweight, easy to convert, and the brushless motor extends battery life. Skip it if you need heavy-duty weed whacking or have a large property—you’ll want a gas or higher-voltage cordless model.
