Worx 3 in 1 Cordless String Trimmer/Lawn Edger/Mini Mower | 12" Electric Weed Wacker with Command Feed, 20V Weed Eater with 5.5 LBS, Battery & Charger Included, WG170.2

What It Is

This is the complete Worx WG170.2 20V cordless string trimmer unit—not a standalone battery or charger accessory. It functions as a 3-in-1 tool for trimming grass, edging sidewalks/driveways, and converting to a mini mower (with optional wheeled kit). Designed for small to medium residential lawns.

Fitment & Compatibility

• Model check: This is the WG170.2 complete tool (includes battery and charger). It is not a replacement battery for other Worx tools—the battery is a 20V 2.0Ah pack (part WA3550.1) and the charger is model WA3742. Only compatible with other Worx 20V Power Share tools.
• Deck/head size: 12-inch cutting width (not 10" or 14"). The trimmer head uses 0.065" or 0.080" line; the included spool is pre-wound with 0.065" line.
• OEM vs aftermarket: This is OEM Worx. Aftermarket batteries (e.g., generic 20V packs) may fit but can reduce runtime or void warranty. No adapter needed for Worx 20V line.
• Physical check: Overall length ~45", weight 5.5 lbs with battery. Ensure your lawn size is under 1/4 acre for comfortable runtime (battery lasts ~20-30 min on high speed).

Key Things to Know

• Battery runtime is limited: The included 2.0Ah battery gives ~20 minutes of continuous trimming. For larger yards, buy a second 20V Worx battery (4.0Ah recommended) or use the included charger (takes 3-5 hours to fully charge).
• Command Feed is finicky: The “tap-and-feed” line advancement works well only with the correct 0.065" line. Using thicker line (0.080") can jam the head. Manual line reloading is straightforward but requires removing the spool.
• Edging mode is easy to switch: Rotate the head 90° and lock it—no tools needed. However, the edging depth is fixed (no adjustable guide wheel), so expect to practice a steady hand.
• Mini mower conversion requires extra purchase: The “mini mower” feature needs the optional WA0189 wheeled kit ($30-40). Without it, you only have trimmer and edger modes.

Should You Buy It

Buy this if you have a small lawn (under 1/4 acre), want one tool for trimming and edging, and already own other Worx 20V tools (since the battery is shared). Skip it if you need longer runtime, prefer a gas trimmer for heavy weeds, or want a true stand-alone mower without buying extra parts.
