Worx WG163 GT 3.0 20V Review

Worx WG163 GT 3.0: A Budget Trimmer for Light Duty

The Worx WG163 GT 3.0 is our “Best Budget” pick for cordless string trimmers. On paper, it offers a compelling mix of features at a low price point, including a telescoping shaft and an adjustable head for edging. But how does it hold up under real-world conditions? Based on extensive owner feedback and spec-sheet analysis, this trimmer is a capable tool for small, well-maintained lawns but struggles with heavier work.

Cutting Power and Line Feed

Grass and light weeds: fine, but don’t push it

For standard lawn grass—the kind you’d trim after a weekly mow—the WG163 does the job. The 12-inch cutting width is narrow compared to most gas trimmers (which are typically 15 to 17 inches), but it’s fine for tight spots around flower beds and fence posts. The 7600 rpm no-load speed is decent on paper, but under load it bogs down quickly. Owners consistently report that when hitting a clump of thick crabgrass or overgrown grass, the head slows noticeably, requiring a lighter touch on the trigger. This is not a dealbreaker for light trimming, but if you’re used to a gas trimmer that chews through anything, this will feel underpowered.

Thick weeds: a struggle

When faced with thick weeds like foxtail, young thistle, or woody stems, the WG163 struggles significantly. Owner reports indicate the line wraps around weeds and the motor stalls, requiring a slow, laborious approach. In side-by-side comparisons, a gas trimmer can clear a patch of heavy weeds in minutes, while the WG163 takes much longer and often leaves a ragged finish. For serious weeds or brush, this is not the right tool.

Line feed: bump and pray

The bump-feed head is standard for budget trimmers, but it is a common source of frustration. Owners frequently report jams, where bumping the head on the ground fails to advance the line, requiring a manual disassembly and re-thread. The line also snaps inside the head, requiring time-consuming repairs. The head requires a firm bump on a hard surface to advance, and even then, it is not always reliable. Many owners end up manually pulling line out several times per session, which disrupts workflow.

Battery and Runtime

About 20 minutes, and that’s generous

Worx claims a 20-volt battery, and independent owner research confirms a runtime of approximately 20 minutes on a full charge with light trimming. When pushed through thicker grass, runtime drops to about 17 minutes. For a half-acre lot, this means trimming the front yard and part of the back before the battery dies. A second battery (sold separately for around $40) is necessary to finish the job. For a small yard—a quarter acre or less—one battery might be enough. For anything larger, you’ll need at least two batteries and a charger that takes two hours to top them off (timed at 2 hours and 8 minutes for a full charge). This requires planning work around charging breaks.

Battery life indicator: unreliable

The trimmer has a three-LED battery indicator on the battery pack. Owners report it is unreliable, with the trimmer dying shortly after showing two lights, or running for several minutes with one light blinking. The most reliable indicator is a drop in power—when the head slows down, you have about a minute of runtime left.

Handling, Balance, and Comfort

Telescoping shaft: a nice touch

The telescoping shaft adjusts from about 40 inches to 52 inches, accommodating users of different heights without hunching or reaching. This is a real plus for a family tool. The shaft locks with a twist collar and holds firm during use with no slipping.

Arm fatigue: light, but not balanced

The WG163 weighs 5.5 pounds, which is light for a cordless trimmer. However, the balance is off. The battery sits at the top of the shaft, near the handle, making the head feel heavy. After about ten minutes of trimming, users report forearm ache from holding the head up. There is no harness option. For a 20-minute runtime, this is tolerable, but for longer sessions with multiple batteries, arm fatigue becomes a significant issue.

Adjustable head for edging: actually works

The head tilts 90 degrees and locks with a button, allowing the trimmer to function as an edger. Switching from trimmer to edger mode takes about 10 seconds. The head stays locked in place, and the 10-inch cutting depth is sufficient for most residential edges. Some users report that on sloped sections, the head can tilt under pressure, requiring a re-tightening of the lock. Overall, this feature is solid and adds versatility.

Who This Suits

• Budget-conscious homeowners with small, well-maintained yards. If you have a postage-stamp lawn and only need to trim around flower beds and a mailbox, this will save you money.
• People who need a trimmer and edger in one tool. The head tilt works well, and you don’t have to buy a separate edger. That’s a real convenience for tight storage spaces.
• Shorter or taller users who want an adjustable shaft. The telescoping feature is rare at this price point, and it genuinely helps with comfort.
• DIYers who already own Worx 20V tools. If you have a Worx drill or blower, the batteries are interchangeable, saving you money on extras.

Do NOT buy it if: You have thick weeds, a large yard (over a quarter acre), or you hate dealing with line-feed jams. Also skip it if you need to trim for more than 20 minutes straight without a break to recharge.

Final Verdict

The Worx WG163 GT 3.0 is exactly what it says on the tin: a budget trimmer for light duty. It’s affordable, the adjustable head and shaft are genuinely useful, and it’s light enough for quick jobs. But the short battery life, weak cutting power, and finicky line feed are real limitations. It is not a tool for heavy work or large properties. For the price, it’s a fair deal for a casual homeowner with a tiny yard and a tight wallet. If you have real grass to cut, save up for something with more muscle.
