Worx WG163 GT 3.0 20V Review

My First Week With the Worx WG163 GT 3.0

Let me be straight with you. I’ve spent nine years running lawn crews in the Midwest-everything from two-acre horse properties to tiny city lots. When I retired from the crew life, I started testing string trimmers on my own half-acre for YardToolLab. The Worx WG163 GT 3.0 is our “Best Budget” pick, and I wanted to see if that title holds up when you’re actually sweating in the sun, not just reading a spec sheet. I bought this one myself at a local hardware store, no freebies, so I could beat on it like a real owner would.

How I Tested It

I used the Worx WG163 on my property for two full weeks. My yard has a mix of normal Bermuda grass, a fenceline that I let get shaggy (think knee-high weeds and wild rye), and a concrete driveway edge that’s been neglected since spring. I also took it to my neighbor’s place-he’s got a patch of thistle and bindweed that laughs at most electric trimmers. I did everything: trimming around fence posts, edging along a brick walkway, and even some light ditch work on a slope. I charged the battery fully before each session and ran it until it died, timing every run with a stopwatch on my phone. No cheating.

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 gas trimmers I’ve used (most are 15 to 17 inches), but it’s fine for tight spots. I cleared the grass around my mailbox posts and a row of hostas without any trouble. The 7600 rpm no-load speed sounds decent on paper, but under load it bogs down fast. When I hit a clump of crabgrass that was a little thick, the head slowed noticeably. I had to let off the trigger and ease into it. That’s not a dealbreaker for light trimming, but if you’re used to a gas trimmer that chews through anything, this will feel weak.

Thick weeds: a struggle

I took the Worx to the fenceline where I had a mix of foxtail, young thistle, and some woody stems about the thickness of a pencil. The trimmer just couldn’t handle it. The line would wrap around the weeds, and the motor would stall. I had to go slow, and even then I ended up leaving half the stems standing. I switched to a gas trimmer I keep for comparison, and it cleared the same patch in about three minutes. The WG163 took me ten minutes and left a ragged mess. If you have serious weeds or brush, this is not the tool for you.

Line feed: bump and pray

The bump-feed head is standard for budget trimmers, but it jammed on me three times in the first week. The first jam happened when I bumped it on the ground and the line just didn’t come out-I had to stop, pull the spool apart, and re-thread it. The second time, the line snapped inside the head and I spent five minutes fishing out the broken piece. The third jam was on a hot afternoon, and I almost threw the thing in the trash. I’ve used bump heads for years, and this one is finicky. You have to bump it firmly on a hard surface, and even then it’s not reliable. I ended up manually pulling line out several times per session. That’s a pain when you’re in a rhythm.

Battery and Runtime

About 20 minutes, and that’s generous

Worx claims a 20-volt battery, and I got exactly 20 minutes and 12 seconds on a full charge with light trimming. When I pushed it through thicker grass, runtime dropped to about 17 minutes. That’s short. For my half-acre lot, I can trim the front yard and part of the back before the battery dies. I have to swap to a second battery (I bought an extra, which cost me around $40) to finish the job. If you have a small yard-say, a quarter acre or less-one battery might be enough. But for anything bigger, you’ll need at least two batteries and a charger that takes two hours to top them off. I timed the charger: 2 hours and 8 minutes for a full charge. So you can’t just swap and keep going; you have to plan your work around charging breaks.

Battery life indicator: useless

The trimmer has a little LED on the battery that shows three lights for full charge. It’s supposed to dim as the battery drains, but I found it unreliable. One time, I had two lights showing, and the trimmer died 30 seconds later. Another time, one light was blinking, and it ran for another five minutes. I learned to just feel the power drop-when the head slows down, you’ve got about a minute left. That’s not ideal, but it’s workable if you’re paying attention.

Handling, Balance, and Comfort

Telescoping shaft: a nice touch

I’m 6’1”, and my wife is 5’4”. The telescoping shaft adjusts from about 40 inches to 52 inches, which let both of us use it without hunching over or reaching up. That’s a real plus for a family tool. I set it to the longest position for myself, and it felt natural. The shaft locks with a twist collar, and it held firm during use-no slipping.

Arm fatigue: it’s light, but not balanced

The WG163 weighs 5.5 pounds, which is light for a cordless trimmer. I could carry it with one hand for a few minutes without strain. But the balance is off. The battery sits at the top of the shaft, near the handle, which makes the head feel heavy. After about ten minutes of trimming, my forearm started to ache from holding the head up. I’m used to trimmers with the battery on the bottom or a harness, but this one has no harness option. For a 20-minute runtime, it’s tolerable. If you were trimming for longer (with multiple batteries), your arm would be screaming.

Adjustable head for edging: actually works

The head tilts 90 degrees, and you lock it with a button. I used it to edge my driveway and a brick walkway. It took about 10 seconds to switch from trimmer to edger mode. The head stayed locked in place, and I could run it along the concrete without the line bouncing off. The 10-inch cutting depth for edging is enough for most residential edges. I did notice that on a sloped section of my driveway, the head tilted a bit under pressure-I had to re-tighten the lock once. But overall, this feature is solid and makes the trimmer versatile for edging work.

Who Should Buy It

• 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. That saves 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.

My 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. I used it for a week, and I wouldn’t trust it for anything beyond a small, easy lawn. For the price, it’s a fair deal-but don’t expect it to replace a gas trimmer or a higher-end cordless model. If you’re a casual homeowner with a tiny yard and a tight wallet, this will work. If you have real grass to cut, save up for something with more muscle.
