WORX GT Revolution: 20V 12″ String Trimmer, Edger & Mini Mower
Battery-powered and lightweight, the WORX GT Revolution 20V is a 3-in-1 trimmer, edger, and mini mower with extendable shaft, auto-feed, and adjustable handle. As someone who grew up cheering on the sidelines and never missed a science class, I’m fascinated by clever engineering—and this tool’s combination of power, reach, and adaptability makes quick work of any yard task. Whether you’re sculpting crisp edges along a flower bed or tackling overgrown patches a main mower can’t touch, the WG170 seamlessly pivots between roles while keeping fatigue at bay.

At its heart, the GT Revolution is a true 3-in-1 design. With a quick twist, the 12″ string trimmer head rotates 360° to become an inline edger, and swapping on the included mini-mower deck lets you stripe in tight corners. This modularity means you carry one tool instead of three—ideal for small-space storage or carrying between beds.
Weighing just 4.04 lbs without battery, it undercuts many corded and gas models by half. Coupled with two 2.0 Ah MaxLithium packs, you can expect roughly 25–30 minutes of continuous run time per battery on light to moderate grass—plenty for the average quarter-acre lawn. And since the batteries snap into any WORX 20V PowerShare tool, you’re not tied to a single use.
The extendable shaft is a welcome evolution from the WG151’s length. By adding nearly a foot, the WG170 lets users of different heights find a natural stance, reducing back bend. This extra length also helps reach under shrubs or fence lines without awkward stretching.
Finally, the Command Feed auto-feed system stands out from bump-feed trimmers. One button press releases fresh line instantly—no more uneven feed or whipping head returns. This is a small feature that pays dividends in flow and efficiency, especially if you’re edging long borders.
Comfort & Control

Ergonomics take center stage with seven handle adjustments and six cutting-head angles. From upright edging to low-sweeping trimming, you dial in the grip and head tilt for natural wrist alignment. This thoughtful pivot system shines during extended sessions, when even a pound or two of extra weight can tip you into fatigue.
The included support wheels click on for edging along sidewalks and driveways, providing a steady sled runner. While they roll best on smooth concrete, they’re less adept on bumpy turf—so I recommend removing them for grass edging and reserving them for paving stones.
Assembly is tool-free: snap on the guard, wheel brackets, handle, and you’re ready in minutes. Storage is equally simple thanks to the quick-fold design—collapse it down for a compact 37″×12″ profile that tucks into a closet or garden shed.
Worx’s choice to maintain the same 2.0 Ah battery footprint across tools creates a whole-home ecosystem. Already have their blower or hedge trimmer? Those same batteries power this WG170, reducing clutter and making spare packs a true backup.
Power & Precision

With a 7,600 RPM motor, the GT Revolution fires through thick fescue and clover without bogging down. On dense patches, a slight angle adjustment and moderate feed speed keep the line spinning cleanly instead of snapping. In tests on turf up to 1 ft tall, a single battery pack delivered just under 30 minutes of cut time—exactly as advertised—before swapping.
Edging felt precise, allowing razor-sharp lines along flower beds and pathways. While the 12″ swath means you’ll need two passes for a typical 24″ bed border, the trade-off is nimble maneuvering around obstacles. The mini-mower deck shines on low, flat grass, creating a crisp stripe that complements a full-sized mower’s work.
Noise levels hover around 85 dB—quieter than a gas trimmer but louder than most corded electrics. You gain freedom of movement without dragging an extension cord, but consider ear protection if you’re in close for extended edging.
Heat management impressed me. After 20 minutes of continuous trimming, the motor housing remained only mildly warm. This suggests effective ventilation and build quality that should stand up to seasonal use without throttling back for cooling.
Extras & Evolutions

Compared to the prior model, the WG170’s extra shaft length and refined head pivot are the biggest upgrades—addressing reach and versatility complaints from long-time Worx users. The addition of a mini-mower deck is also new, rounding out the 3-in-1 promise.
The flower guard accessory protects blooms when trimming around delicate plants. It’s spring-loaded for quick adjustment, though it doesn’t lock rigidly; I found a gentle tap sometimes nudged it out of position. A lock-in design would elevate this thoughtful inclusion.
Included spools (three pre-wound) provide about 50 ft of line total. Given the auto-feed cuts small segments off each start, I recommend purchasing a refill roll—many DIYers report that bulk string and manual winding are more cost-effective over time.
Finally, assembly-free means you won’t fumble with wrenches, yet the trade-off is that the whole shaft is plastic-reinforced. It feels durable but lacks the rigidity of metal-shaft competitors. For most residential users this is fine, but if you’re tackling rugged terrain daily, you may prefer a metal-shafted pro model.
Conclusion: Should You Buy the WORX GT Revolution WG170?
If you value versatility, light weight, and the freedom of cordless yard work, the WORX GT Revolution WG170 is an outstanding pick. Its seamless 3-in-1 transformation, extendable shaft, and auto-feed line system address the top pain points of trimming, edging, and mini-mowing smaller areas. While the single-port charger and plastic shaft may not suit every power-user, homeowners with up to a ¼-acre lawn will find this tool a joy to wield. In short, if you’re looking to streamline your gardening arsenal with one smart, science-driven gadget, the WG170 deserves serious consideration.
