WORX WG170 GT Revolution 20V 12" 3-in-1 Cordless String Trimmer
| Power Source | Battery Powered |
|---|---|
| Cutting width | 12 inches |
| Speed | 7600 rpm |
| Number of Batteries | 2 Lithium Ion batteries required. (included) |
The WORX WG170 GT Revolution is a versatile battery-powered tool that serves as a string trimmer, in-line wheeled edger, and a small-area mini-mower. It is typically used for routine yard cleanup, precision edging along sidewalks and beds, and finishing strips that a full-size mower cannot reach. Notable features include a patented Command Feed button that advances fresh line without bumping, a seven-position adjustable handle for comfortable use, and twin support wheels for steady, accurate edging. The included two 20V batteries let you work through a typical quarter-acre yard without swapping brands, and the 12-inch cutting width and 7600 rpm motor provide effective cutting for small to medium lawns. Practical benefits are reduced fatigue from the 5.5 lb weight and easier, neater edges thanks to the wheeled guide and pivoting head. Limitations are typical of compact 20V tools: the 12-inch cutting swath and 2.0Ah batteries mean it is not ideal for heavy brush or large properties and run time is shorter than higher-voltage cordless models.
Best for: Buyers who want one compact tool to handle regular trimming and precise edging around a small to medium yard and who value convenience and low fatigue over raw power.
Less Ideal for: Homeowners with large acreage, dense overgrowth, or frequent heavy-duty clearing needs should consider higher-voltage or dedicated landscaping equipment instead.
- Three-function design converts quickly between trimmer, wheeled edger, and mini-mower for versatile yard work.
- Command Feed automatic line advance speeds work by adding fresh line at the push of a button.
- Lightweight 5.5 lb body and adjustable handle reduce user fatigue during longer edging or trimming sessions.
- Includes two 20V PowerShare batteries and charger so you can finish small-to-medium lawns without buying extras.
- 12-inch cutting width and 2.0Ah batteries limit continuous run time and make it unsuitable for heavy-duty clearing.
- Not designed for thick brush or very large lawns where higher-voltage or gas models perform better.
Verdict: Choose this if you want a lightweight, multi-function trimmer that makes clean edging and quick small-area mowing easy.

Choosing the Right Lawn Edging String Trimmer: Key Factors to Consider
Cutting Width and Line Strength
How wide the tool cuts in a single pass affects how many passes you need along a border. A wider cutting width speeds work on long runs but can make precise vertical edges harder if the line is too flexible. Line diameter and material influence how cleanly the edge cuts through grass and light roots. Thicker or reinforced lines hold shape better for a sharp vertical face, while thin, flexible lines are less likely to damage delicate plantings but may require more passes.
Also consider whether the head supports different line sizes or quick-change spools. Being able to swap to a heavier line for tough edges and a lighter line for fine work adds versatility without buying a second tool.
Handling, Balance, and Vibration
Edging is often a repetitive side-to-side motion close to beds and hardscaping, so comfort matters. Tools with poor balance or high vibration lead to fatigue and less accurate lines. Look for machines with anti-vibration features, comfortable grips, and adjustable harness or shoulder strap compatibility for longer jobs. Shaft length and whether the tool is straight or curved also change how you position the head next to borders.
A lighter tool helps for short, detailed edging, while a slightly heavier, well-balanced model can be easier to control over a straight run. Consider your typical edging session length when weighing weight versus vibration reduction.
Head Design and Ease of Line Replacement
A head that is simple to reload and that holds line securely reduces downtime. For edging, a head that offers stable spool retention prevents uneven cutting lines that can ruin a sharp edge. Some designs allow bump-feed advancement, while others use fixed-length spools or automatic systems. Each has tradeoffs in reliability and user convenience.
Also check how exposed the head is near plants and hardscaping. A protective cover or well-placed guard helps avoid nicking pavers and bark when working close to edges.
Power Source and Endurance for Typical Edging Jobs
Consider whether battery runtime or fuel capacity matches how you maintain borders. For small yards, a single battery charge or a compact fuel tank may be enough. Larger lawns or frequent edging sessions demand longer endurance or quick-change battery systems. Power delivery should be steady at the moderate speeds used for edging; tools that bog down under load will make clean edges harder to achieve.
Also factor in recharge or refueling logistics. Battery tools add simplicity and lower vibration, while gas options often provide longer continuous run time and higher torque for stubborn roots.
Reach, Shaft Type, and Maneuverability
Shaft length and shape affect access behind obstacles and the precision of the edge line. A straight shaft often reaches under low branches and into tight spots, while a curved shaft can offer slightly lighter handling and better balance for close-in trimming. Adjustable lengths and pivoting heads help you maintain a consistent angle along uneven terrain and around corners.
Maneuverability also matters when following long borders that change direction. A head that tilts or rotates smoothly lets you maintain the same cutting plane without reorienting your body constantly.
Edging Techniques for a Crisp Vertical Face
The basic technique is to hold the head at a slight angle so the line bites vertically into the turf, then walk a slow, steady line keeping your wrist motion minimal. For tight corners, use short controlled strokes rather than long swings to avoid scalloped edges. When starting a new boundary, make a shallow guide cut first and then deepen it in a second pass for a sharper face.
Work with the grass when it is drier and slightly longer; wet turf clumps and can tear rather than slice cleanly. After a pass, use a flat-edged tool or half-moon edger to tidy any remaining material for a museum-quality finish.
- Hold the trimmer so the cutting plane is vertical for a straight edge
- Make two passes-shallow then deeper-to control accuracy
- Use short strokes around tight curves to prevent scalloping
Battery Versus Gas: Which Fits Your Edging Routine
Battery models usually offer quieter operation, lower vibration, and easier start-up, which is helpful for short to medium sessions and for neighborhoods with noise restrictions. If your borders are small or you own exchangeable batteries, battery trimmers often cover routine edging comfortably.
Gas tools still lead on continuous runtime and torque for larger properties or when edging through thicker, damp grass and shallow roots. They require more maintenance but can finish long runs without battery swaps. Consider the storage and maintenance tradeoffs when picking a power type.
- Battery: quieter, less vibration, convenient for short tasks
- Gas: longer continuous run, more torque for tough edges
Maintaining a Sharp Edge Over the Season
Regularly inspect and replace worn line so cuts remain clean. Worn or frayed line causes jagged edges and increases the number of passes needed. Check the head for debris build-up and clear grass clippings and soil after each use to prevent imbalance and wear.
Rotate where you edge slightly each season to avoid creating a permanent trench that hampers mower wheels and irrigation. Repair any soil collapse with fresh topsoil and reseeding if necessary to maintain a solid, vertical edge.
- Replace line at the first sign of fraying
- Clean the head after use to prevent imbalance
- Seasonally reset and reseed high-traffic borders
Accessories That Improve Edging Results
Simple accessories can make a big difference. A shoulder strap or harness reduces fatigue on long runs and helps maintain a consistent cutting plane. Edge guides or temporary stakes help you follow a straight line when installing new borders. A small hand edger or half-moon tool is useful for finishing touches where the string trimmer cannot reach cleanly.
Also consider spare spools, a line-winding tool, and a small toolkit for head repairs. Having the right spare line diameter on hand saves time when you need to swap from fine to heavier line for tougher sections.
- Use a strap or harness for long edging sessions
- Edge guides help lay in a straight new boundary
- Keep spare spools and a basic toolkit ready
Safety Practices When Edging Near Landscaping
Wear eye protection and long pants; edging throws small debris that can chip pots or injure bare skin. Be mindful of plants and tree trunks when angling the head to avoid bark damage. Work slowly around hard edges like concrete and pavers to prevent chipping or accidental strikes.
Clear the area of small stones, toys, and garden tools before starting. Turn off the tool before making adjustments or clearing jammed line to avoid accidental starts and injuries.
- Wear safety glasses and protective clothing
- Keep a safe distance from hardscaping and delicate plants
- Power down before servicing the head or clearing jams
How We Chose the Best Lawn Edging String Trimmer
We focused on features that matter for clean, repeatable edging rather than general-purpose trimming. Key evaluation criteria were cutting width and line control, because an even edge depends on how the line behaves and how wide a single pass will be. Handling and vibration were assessed to reflect real gardener comfort during extended edging sessions. Battery life or fuel endurance was considered in relation to typical edging jobs rather than maximum run time alone. Durability of the head and ease of replacing or advancing line were included to minimize downtime and maintenance. Maneuverability and shaft length choices were judged for how they affect access around beds, fences, and tight corners. Excluded from consideration were units designed exclusively for heavy brush clearing, commercial contractor-spec machines, and tools that require specialized fuels or fittings. We prioritized practical homeowner use cases and equipment that balances edging precision with straightforward maintenance and ergonomics.
FAQ
How often should I replace the trimmer line for edging?
Replace the line when you notice fraying or a drop in cutting quality, which is often after several hours of use depending on grass type. For regular seasonal maintenance, check the line before each major edging session and carry spare spools.
Can I use a standard string trimmer for precise edging?
Yes. Many string trimmers can produce a precise edge if you use the correct line diameter and technique. Some models have dedicated edging modes or pivoting heads that make achieving a vertical face easier.
Is a straight shaft or curved shaft better for edging?
Straight shafts often reach further and can be better behind obstacles and under low branches, while curved shafts can feel lighter and better balanced for close-in work. The best choice depends on the layout of your borders and personal comfort.
What line type works best for clean edges?
A round or star-shaped reinforced line tends to hold its shape and cut cleaner vertical faces, while very thin line may flex and tear. Thicker lines resist wear from hitting soil at the edge of the grass, which helps maintain a crisp line.
How do I avoid scalloped or uneven edges?
Use short controlled strokes around curves, keep the cutting plane vertical, and make a shallow first pass before a deeper follow-up pass. Consistent walking speed and minimizing wrist movement also help produce an even edge.
Are there maintenance steps to extend head life?
Yes. Clean the head after each use to remove grass and dirt, inspect for cracks or wear, and replace worn components promptly. Proper storage and avoiding contact with hard surfaces reduce premature damage.
Final Verdict
When choosing a lawn edging string trimmer, prioritize how and where you will use it. If you need quiet, low-vibration work for small to medium borders, battery-powered, well-balanced tools are often best. For longer runs or tougher grass and shallow roots, prioritize endurance and torque. Consider head design and line options to keep edges clean with minimal maintenance. Balance reach, handling, and head durability against the typical size of your borders. With those tradeoffs in mind, you can pick an edging-focused trimmer that makes routine border maintenance quicker and yields consistently sharper results.
