WORX String Trimmer Cordless GT3.0 20V PowerShare 12" Edger & Weed Trimmer (2 Batteries & Charger Included) WG163

A lightweight trimmer can be the difference between a quick tidy-up and an afternoon chore. The Worx GT 3.0 cordless trimmer/edger hits that sweet spot for homeowners who want respectable power without the noise, fumes, and heft of gas. After several weeks of cutting grass along fences, beds, and a long driveway, here’s how it stacked up.

What it is and what you get

The GT 3.0 is a 20V, 12-inch, single-line trimmer that converts to an edger. In the box you’ll find the tool, two 20V lithium batteries, a charger, a pre-loaded spool, support wheels, and a safety guard. On paper: 7,600 rpm no-load speed, 0.065-inch line, and a bare weight of about 5.3 lbs. In practice, it’s a compact setup that’s easy to carry around the yard and simple to store.

Design and ergonomics

The GT 3.0’s head pivots 90 degrees, which sounds like a minor feature until you’re trimming under shrubs or along a sloped section of lawn. That tilt, combined with the rubberized guide wheels for edging, makes it straightforward to reach awkward spots and keep a line straight at the curb.

Balance is generally good in trimmer mode, with most of the weight low and close to the cutting head, which helps accuracy around delicate borders. Swapping to edger mode shifts the balance a bit forward, and it can take a minute to find the best hand position, but once you do the wheels do their job. The adjustable spacer guard is genuinely useful; flip it out near fences, garden edging, or landscape lights and it saves you from nicking things you’d rather not.

At just over five pounds without a battery, it’s easy to handle for extended sessions. With a battery installed, it’s still light enough that fatigue isn’t a major issue for most folks. Vibration is low, and the sound level is typical of a compact cordless trimmer—audible, but nowhere near a gas unit.

Performance as a trimmer

The 12-inch cutting swath is a good match for small to medium suburban yards. It’s wider than compact 10-inch models, so you cover ground faster, but it doesn’t demand the power of a larger 13–15 inch head. At 7,600 rpm, the GT 3.0 has enough speed to slice through lawn grass cleanly and handle moderate weeds. Where it starts to show limits is in dense, woody stems or very tall, thick growth; the 0.065-inch line can chew through those, but it takes patience and multiple passes.

The cut quality on typical turf is neat, and the tool’s lighter weight actually helps with precision near edging stones and flower beds. It’s not a brushcutter, and it doesn’t pretend to be, but for weekly lawn maintenance it has the right balance of power and control.

Edging capability

Switching to edger mode is quick, and once you’ve dialed in your hand position, the wheels keep the path straight. I found the best results by letting the wheels lightly ride the hard edge (curb or walkway) with the spacer guard retracted. It won’t bite into compacted soil like a dedicated, bladed edger, but for maintaining an existing edge it does a tidy job and noticeably sharpens the lawn’s look.

On longer edging runs, the single-line setup is fine, though it will require the occasional line advance to maintain a crisp cut. If you’re maintaining hundreds of feet of edge every week, you may crave a beefier double-line system, but the GT 3.0 is more than adequate for typical residential edges.

Line management and the Command Feed

The push-button Command Feed is one of the reasons this tool is approachable. Instead of bumping the head, you tap a button on the handle to advance line. It’s consistent and keeps you from inadvertently feeding out too much line on a bump. A practical tip: tap the button once before you start a new pass or if you notice the cutting width narrowing. Over-advancing wastes line; under-advancing leads to ragged cuts. The included pre-wound spool is easy to swap, and using 0.065-inch line means plenty of aftermarket options if you prefer to wind your own.

Worx promotes free spools for life for this platform—worth checking the current terms and shipping costs—so you’re not locked into expensive consumables.

Battery life and charging

With two 20V packs included, the GT 3.0 is “ready to mow” in cordless terms. Runtime varies with grass thickness and how often you edge, but expect roughly one typical trimming session per battery on a modest yard. On my 1/4-acre lot—with fence lines, beds, and a driveway edge—I can trim and touch up some edging on a single battery if I work efficiently. Heavier growth and lots of edging will dip that runtime. The second battery eliminates range anxiety, and swapping packs is quick.

The included charger is compact and uncomplicated. It’s not a rapid charger, so plan to rotate batteries if you’re doing marathon yard days. For most users, charging between weekly sessions is a non-issue.

Build quality

Construction is sturdy for the weight class. The plastics feel dense, the locks and latches click positively, and the guard doesn’t flex excessively. I appreciate the clear line-cutting blade on the guard—it trims excess line to the correct length automatically. After bouncing off a few stones and edging along concrete, the head shows normal wear but nothing alarming. Keep the tool clean and inspect the wheels occasionally; they’re what keep your edges straight.

Platform and compatibility

This trimmer runs on the Worx PowerShare platform, so the included 20V batteries can power other compatible 20V and 40V Worx tools. I’ve run the same packs in a compact blower for cleanup after trimming, and the interchangeability is convenient. If you’re mixing batteries from different generations or buying tools in different regions, verify that the pack interface matches your tool—PowerShare is broad, but there are variants. For most buyers staying within the current Worx lineup, it’s a straightforward, useful ecosystem.

Where it fits

• Best for: Small to medium lawns, weekly maintenance, homeowners who value light weight and convenience over raw grunt.
• Acceptable for: Occasional edging of established edges, moderate weeds, light work on slopes and under shrubs.
• Not ideal for: Thick, woody weeds, acres of overgrowth, or users who expect a double-line, heavy-duty cut.

What I’d improve

• Line size and head: A dual-line head or support for 0.080-inch line would extend capability into heavier growth. The 0.065-inch line is efficient but not robust.
• Edger balance: The edger wheels work, but the balance shifts forward in edger mode. A slightly different wheel placement or a micro-adjust would make it even steadier.
• Charger speed: A faster charger option in-box would benefit users who plan to work longer sessions in a single day.

Practical tips for better results

• Tackle thicker patches first on a fresh battery; finish with lighter touch-ups as voltage sags.
• Use the spacer guard whenever you’re near fences, mulch edging, or low landscape lights.
• Advance line with a quick button tap before starting longer passes; resist the urge to overfeed.
• Keep a spare spool on hand. Swapping mid-job takes seconds and keeps your rhythm.
• Let the wheels guide you when edging—light contact beats pressing hard into concrete.

Verdict and recommendation

The Worx GT 3.0 earns its keep by being easy to pick up, simple to operate, and capable of leaving a yard looking clean without a lot of fuss. It’s not built for battle with saplings, and it won’t replace a dedicated, bladed edger for cutting new edges into compacted soil, but that’s not its mission. As a lightweight, do-most-of-what-you-need trimmer/edger with smart line feeding and a genuinely useful tilt head, it hits the mark.

I recommend the GT 3.0 for homeowners with small to medium lawns who want a no-hassle cordless trimmer that also edges well enough to maintain established lines. The included second battery, the approachable weight, and the thoughtful features—Command Feed, pivoting head, edger wheels, and spacer guard—make it a practical, good-value choice for weekly lawn care. If your yard routinely throws heavy, woody growth at you, or you demand double-line cutting power, look toward a heavier-duty model. For everyone else, this is an easy tool to live with and a solid addition to a 20V yard-care kit.
