A crisp lawn border can sharpen the appearance of your entire yard, especially around walkways, driveways, and garden beds. You need either a dedicated blade edger or a string trimmer that pivots into edging mode, along with enough runtime and maneuverability for your yard size. The six options below include compact cordless models, multi-tool systems, mower conversions, and replacement line designed for compatible BLACK+DECKER equipment.
Your Options, Compared
More On The Choices That Made The List
The Greenworks 40V 16 in Cordless Trimmer is built for broad passes around fences, garden beds, and driveway edges. Its 16-inch cutting swath reduces the number of strokes across long borders, while the included 4.0 Ah battery removes cord management from routine yard work.
For most suburban lawns, the balance of reach and cordless operation looks useful. You’ll handle ordinary grass and light overgrowth without setting up a fuel supply, although a dedicated blade edger may produce a straighter line against hard surfaces.
Useful Strengths
- The 16-inch swath covers substantial border length per pass.
- Its 40V battery platform supports convenient cordless cleanup.
- The wider reach suits long fences and open lawn perimeters.
Points To Note
- String wear, debris removal, and occasional line replacement require basic maintenance.
- A wide head can be less precise in very narrow planting beds.
At A Glance
Who Will Love This
You’ll appreciate this trimmer most as a homeowner maintaining long edges around a medium or large lawn.
Where Another Pick Shines
The WORX WG898.9 suits you better when precise blade edging matters more than a wide trimming pass.
This two-pack contains replacement trimmer line rather than a mower, edger, or motor. It serves the practical role of keeping compatible BLACK+DECKER equipment supplied, especially for homeowners who prefer corded tools and already own a supported conversion model.
The 30-foot spools and autofeed format simplify replacements after line breaks down. You still need a compatible mower, trimmer, or edger, so this selection has little standalone value for someone starting from an empty tool shed.
A Few Highlights
- Two spools provide more line for continued yard work.
- Autofeed line suits tools with compatible feed mechanisms.
- The 0.065-inch diameter supports several listed mowers and trimmers.
Practical Considerations
- Check your tool’s model number against the compatibility list before ordering.
- Line can tangle or wear around nozzles, so periodic inspection remains necessary.
- This package does not provide the cutting head or power unit.

Made For In Mind
This package fits you best as an existing BLACK+DECKER owner maintaining a compatible corded yard tool.
Consider Something Else When
The CRAFTSMAN V20 kit is a better fit when you need a cordless machine, battery, charger, and two operating modes.
A dedicated blade makes more sense than string for many hard-edged surfaces, and the WG898 keeps that approach compact. Its 7.1-inch blade and three depth settings, covering 1.5, 1.75, and 2 inches, let you tune the cut for sidewalks, patios, and modest garden borders.
For smaller lawns, this focused design may feel easier to manage than a wide mower conversion. The tradeoff is a narrower work area, so long perimeter jobs take more passes and a brushless motor still needs a compatible 20V battery and charger.
Real-World Strengths
- The blade supports cleaner cuts against sidewalks and patios.
- Three depth settings adapt the visible edge to different beds.
- Its compact format suits narrow paths and smaller storage areas.
Worth Bearing In Mind
- A 7.1-inch blade covers less ground than a string-trimmer head.
- Battery and charger availability should be checked before purchase.
Right Fit For
You’ll find this model most useful for precise edging in compact yards with frequent patio or sidewalk borders.
Reach For A Different Pick When
The Greenworks 40V 16 in Cordless Trimmer better serves long lawn edges where grass dominates.
The WG898.9 carries the dedicated-edging approach of the earlier WG898 with a streamlined blade and brushless motor. Its 7-inch cutting area and guide make it practical beside driveways, garden paths, and patios where a crisp separation between pavement and grass matters.
With a 4.0 Ah PowerShare Pro battery, the listed configuration can cover as much as 2,800 feet per charge, depending on grass density and cutting conditions. That makes the compact blade more useful across a medium yard, though the battery’s exact inclusion should be confirmed on the listing.
The Good Stuff
- The streamlined blade supports controlled edging beside hard surfaces.
- Up to 2,800 feet of listed coverage suits long border projects.
- The brushless motor reduces routine maintenance demands.
Small Caveats
- A dedicated blade handles less width per pass than a mower.
- Guide placement demands a steady pace to avoid wandering.
Quick Facts
Who Should Grab It
You’ll appreciate the WG898.9 most for medium-yard edging where cordless freedom and a defined blade path both matter.
A Better Fit Elsewhere
The Worx WG733.1 mower fits larger small-space lawns that also need regular mowing between edging sessions.
One machine can handle tall grass and then pivot into an edging position, which makes the CRAFTSMAN V20 kit appealing for mixed garden maintenance. Its 13-inch swath covers a useful middle ground between the Greenworks’ 16-inch reach and the narrow WORX blade.
Turn-To-Edge operation changes the head’s orientation for border work, while two speed settings let you favor cutting output or runtime. The included 4 Ah battery and charger make the package more complete than several bare-tool choices, and up to 63 minutes of listed runtime provides room for a medium lawn.
What Pays Off
- Its two speed settings suit grass density and runtime priorities.
- The 13-inch swath handles both trimming and edging duties.
- Included battery and charger reduce extra accessory planning.
Possible Compromises
- The line head may be less exact than a dedicated blade.
- Its listed runtime varies with speed and grass conditions.
- Keep the head clear of stones and hard debris during use.
Built For In Mind
This kit suits you well as a homeowner who wants one cordless tool for overgrowth, open borders, and occasional edging.
Another Choice May Suit
The WORX WG898.9 fits you better when a dedicated blade is the priority and precise lines outrank trimming versatility.
The WG733.1 is primarily a small mower with a secondary edging mode, which makes it more useful than a narrow edger for complete lawn maintenance. Its 14-inch cutting deck handles compact plots, while a brushless motor supports efficient cordless operation and reduced mechanical upkeep.
The included 20V 5.0 Ah PowerShare Pro battery is rated for lawns up to 3,200 square feet on one charge. For urban yards with tight storage, that balance may be useful, though you’ll trade the dedicated control of a blade edger for broader mowing capability.
Everyday Wins
- The 14-inch deck suits compact lawns and narrow storage spaces.
- Two-in-one design handles mowing and edge detailing.
- The included battery supports small-yard lawn coverage.
Less-Strong Areas
- The 14-inch deck is less efficient on broad open lawns.
- Conversion mode may need more frequent alignment checks.
The Right Fit
You’ll find this mower most practical for apartment yards, townhouse lawns, and other compact spaces needing mowing and edging.
Swap It Out When
The CRAFTSMAN V20 kit better fits larger mixed tasks requiring wider trimming reach and a separate edging conversion.
Choosing A Machine For Clean Lawn Borders
Blade or String
A blade edger cuts with a sharpened metal disk, which gives you a more defined line along sidewalks and patios. A string trimmer uses a rotating nylon line and handles grass, weeds, and irregular garden edges with greater reach.
Battery System And Runtime
Cordless equipment needs enough energy for your lawn’s perimeter rather than just its open center. A 4.0 Ah or 5.0 Ah battery can reduce interruptions, but battery size alone doesn’t determine runtime. Speed, grass density, blade width, and battery condition also affect each session.
Width And Maneuverability
A 13- to 16-inch trimmer covers long fences efficiently, while a 7-inch blade gives you finer control near obstacles. In compact yards, maneuverability often matters more than maximum cutting width, especially around trees, garden ornaments, and tight corners.
Included Accessories
Check the package before shopping. A bare edger or mower may require separate batteries and a charger, while the CRAFTSMAN V20 kit includes both. The BLACK+DECKER pack contains replacement line rather than a powered machine, so verify your existing tool’s compatibility.
Avoiding Common Category Errors
Common Shopping Slip Ups
Choosing by cutting width alone can leave you with an awkward machine. A narrow blade suits precision work, while a wide trimmer reduces passes across open borders. Also confirm battery and charger inclusion, since bundles vary widely.
What The Upgrade Payoff Covers
A brushless motor can reduce routine maintenance compared with a conventional brushed motor, while a larger battery extends useful work between charges. Those additions matter most for medium or large lawns where interruptions become inconvenient.
Frequently Asked Questions
Can a lawn mower edge a lawn effectively?
A mower with a dedicated edging mode can detail lawn borders, though a separate edger usually provides more precise control.
Are cordless lawn edgers suitable for large yards?
Battery capacity, cutting width, and grass density determine suitability. Larger yards generally benefit from wider blades or higher-capacity batteries.
Is trimmer line less precise than a blade?
Yes, string is usually better for flexible vegetation, while a blade creates a cleaner line against pavement and hard borders.
Do replacement spools include a battery?
No, BLACK+DECKER trimmer-line spools contain line only, and you need a compatible powered tool to use them.
Can one tool handle both mowing and edging?
Some multi-function models combine mowing and edging modes, but dedicated tools often provide better control for each task.
