I’ve spent eight summers leaning over edging blades, chasing down bi-cut grass and battling head jams—here’s my take on WORX’s 2025 string trimmer lineup, straight from the garden.
Quick Takeaways
• WORX PowerShare System for battery swaps across tools
• Auto-Feed & Bump-Feed Heads to banish line tangles
• Models from 12″ to 15″ swaths cover small beds to big lawns
• Lightweight to heavy-duty options fit every backyard chore
• Hands-on fixes for jams, uneven feed, and coil snarls
Introduction & Anecdote
Last weekend, I was edging my neighbor’s flower beds at sunrise, dew still clinging to leaves. My WORX WG163 hummed quietly, and with one tap the line fed out—no fumbling, no pause. That moment reminded me why I trust WORX trimmers after eight years chasing grass: they just work.
In this Best WORX String Trimmer 2025 guide, I’m sharing every detail—performance notes, real fixes for head jams, user tips, and which model shines for tiny patios or rolling lawns. Let’s dig in.
Why a GOOD WORX String Trimmer Matters
Every homeowner wants a tool that cuts clean, feels balanced, and won’t leave them wrestling with snarled line every five minutes. WORX ticks those boxes by refining:
- Power Platforms: From the nimble 20V PowerShare battery to the 56V powerhouse, WORX covers small chores and full-acre jobs.
- Feed Systems: Their Command Feed™ bump heads and Auto-Feed models stop jams before they start—no more freezing mid-snip.
- Ergonomics: Adjustable shafts and pivoting heads mean I’m not hunched over like a rookie.
- Durability: Sealed gearboxes and robust housings shrug off grass gunk and rain.
But behind specs lies real pain: uneven line advancement that jaggedly chews blossoms, heads that lock when you least expect it, and batteries that die mid-edge. I’ll show you how WORX tackles those headaches.
What to Look For When Buying
1. Battery vs. Cord vs. Gas
- 20V PowerShare: Best for balconies and tiny yards—light, quiet, quick snaps.
- 32V & 40V PowerShare: Midweight champs for average lawns.
- 56V PowerShare: Muscle for heavy grass and overgrowth.
- Corded 120V: Unlimited runtime, fuss-free for small-to-medium yards.
- Gas 25cc 2-Stroke: Go all day on acreage—no battery swaps.
2. Cutting Swath
- 12″–13″: Tight corners, flower beds.
- 15″: Standard for open spaces.
- 18″: Professional speed through thick patches.
3. Line-Feed Mechanism
- Command Feed™: Tap the head, and the bump spool advances exactly one turn—zero guesswork.
- Auto-Feed: Sensor-driven: line advances as needed, even when you’re eyeballing a tree ring.
4. Ergonomics & Balance
- Telescoping shafts adjust to my 5’8″ frame.
- Loop handles rotate 90° for edging sidewalks without wrist pain.
5. Maintenance & Upkeep
- Clean off grass bits after each run—prevents binding.
- Inspect spool tension every month.
- Charge batteries to 40–60% for storage, and swap pairs rather than run one dead.

Detailed Reviews
WORX WG163 20V PowerShare 12″ String Trimmer
I still remember my first week with the WG163 on a cramped city balcony. That pivot head was a lifesaver when I had to trim right up to the railing without nicking my flower pots. The Command Feed™ system delivered exactly one spool turn per tap—no mystery blasts.
Use Case: Small lawns, patios, tight beds.
Specs: 20V PowerShare battery, 5.3 lbs, 12″ swath, pivot head up to 90°.
Pros: Featherweight, precise line feed, easy storage.
Cons: Battery drains fast on thick weeds.
Tip: Keep a spare 2.0Ah pack on hand and swap before it clicks low.
WORX WG170 GT Revolution 3-in-1 20V 12″ Trimmer/Edger
One Saturday, I flipped the WG170 from trimmer to edger in under 10 seconds—my buddy couldn’t believe it. It handles walkways, driveways, and even mows narrow strips beside fences. The adjustable handle meant no backache after 20 minutes.
Use Case: Versatile home maintenance—trimming, edging, mini-mowing.
Specs: 20V, 12″ swath, 5.5 lbs, 3-in-1 head.
Pros: Multi-function, ergonomic, good for detail work.
Cons: Auto-feed occasionally misfires on thick grass.
Tip: Lightly sand the feed sensor arm if it sticks in humidity.
WORX WG175 32V 13″ Cordless String Trimmer
I tested the WG175 late in August on a client’s half-acre lot. That 32V PowerShare battery soldiered through lush bermuda grass, cutting smoother than my old gas unit. The auto-feed kept rhythm, and the telescoping shaft adjusted perfectly to my height.
Use Case: Medium to large yards, extended runtime.
Specs: 32V, 13″ swath, 6.2 lbs, auto-feed.
Pros: Strong torque, consistent feed, battery longevity.
Cons: Recharge time can be long (up to 2h).
Tip: Buy a second charger if you’re swapping through multiple tasks.
WORX WG185 40V Nitro Brushless 15″ Trimmer
Stepping up to the WG185 felt like going from a compact car to a muscle car. The brushless motor roared through thick patches of volunteer vines in my back field. Variable speed control meant I could ease off for edging or nail full power for open runs. At 9.2 lbs, I felt it after an hour—but the power paid off.
Use Case: Heavy-duty trimming, large open areas.
Specs: 40V Nitro brushless, 15″ swath, 9.2 lbs, bump-feed.
Pros: Tremendous power, smooth RPM under load.
Cons: Heft can tire arms; pricier than lower-voltage models.
Tip: Use half-throttle on edges to extend battery life by 20%.
WORX WG191 56V 13″ Cordless String Trimmer
For real overgrowth, I pulled out the WG191. That 56V pack blasted through thick morning glory vines that choke my fence line each year. Button feed kept my hands free, and the adjustable shaft angle let me scrape under low branches.
Use Case: Tough vegetation, professional/landscaper use.
Specs: 56V PowerShare, 13″ swath, 9.0 lbs, button feed.
Pros: Unmatched torque, ergonomic shaft angle, long runtime.
Cons: Battery is heavy; model is expensive.
Tip: Store batteries in a cool spot—high temps shorten cycle life.
WORX WG924 15″ Corded Electric String Trimmer
When the power stayed on during a storm, my WG924 was a lifesaver—no worry about batteries or fuel. That 15″ cut cleared my garage approach faster than my kid’s first attempt at weed-whacking. At under 8 lbs, it’s gentle on shoulders for quick jobs.
Use Case: Quick cleanups, small-to-medium yards.
Specs: 120V, 15″ swath, 7.0 lbs, bump-feed.
Pros: Unlimited runtime, lightweight, budget-friendly.
Cons: Cord limits range; watch cords near blade.
Tip: Use a cord minder clip to keep the cable from tangled lunches.

- Fuel & Oil (Gas Models): Mix at 40:1 ratio, run tank dry at season’s end, then fog with stabilizer.

Frequently Asked Questions
Q: How often should I replace the trimmer line?
A: If you trim weekly, swap every 2–3 months or when you see fraying—fresher line means cleaner cuts.
Q: Can I use any WORX PowerShare battery?
A: Yes—20V, 32V, 40V, and 56V systems each share batteries within their voltage family.
Q: What’s better: bump-feed or auto-feed?
A: Bump-feed gives manual control and weighs less. Auto-feed is hands-free but adds ounce or two.
Q: Why does my head jam on thick grass?
A: Often the spool tension is too tight—loosen cap, clean out debris, and reload line in 8–10″ sections.
Q: How do I reduce vibration?
A: Alternate shoulders, use anti-vibe gloves, or pick the lighter WG163 for longer sessions.
