Best Cordless Weed Whacker for Different Yard Sizes

#1 · Best Overall

1. Greenworks 80V Trimmer

• Dimensions L x W: 65"L x 7.5"W
• Weight: 16 lb
• Size: 16" Brushless – Gen 1 (2.0Ah)

Best for: Wide-path demanding yard work.

Why it ranks #1: Its 80V platform, 16-inch cutting path, .080-inch dual line, and included 2.0 Ah battery suit demanding trimming and wider areas.

A 16-inch cutting path with .080-inch dual line gives the Greenworks 80V trimmer a broad sweep for demanding yard maintenance and larger lawns. Its brushless motor runs on the 80V platform, and bump-feed line advancement lets users release more line by tapping the head rather than stopping to adjust it manually.

The wide dual-line cutting path can cover more ground per pass, while .080-inch line is specified for efficient trimming and cleaner cuts through tough grass and weeds. Bump-feed advancement keeps line management in the user’s hands during work. The kit includes a 2.0Ah battery, charger, guard, and auxiliary handle. As part of Greenworks’ 80V platform, the battery system is positioned for users who want compatible tools within that voltage family.

Skip it if you want a 40V combo with a blower for cleanup; the Greenworks STBA40B210 includes both tools.

Consider it for larger lawns or demanding trimming where a wide path and dual line matter. The included 2.0Ah battery and 80V platform are central fit considerations, particularly for buyers planning extended sessions or choosing compatible yard tools.

#2 · Longest Stated Runtime

2. CRAFTSMAN V20 Trimmer

• Dimensions L x W: 31.72"L x 7.72"W
• Size: 13 in

Best for: Longer sessions across wider lawns.

Why it ranks #2: It offers up to 63 minutes of stated runtime, a 13-inch cutting swath, and a 4Ah battery and charger in the kit.

CRAFTSMAN lists up to 63 minutes of runtime from the V20 kit’s 4Ah battery, making it a candidate for longer trimming sessions without a mid-job battery change. Its 13-inch cutting swath and motor rated for 52% more power support faster coverage through thick grass, while the same tool also serves as an edger.

The 13-inch swath covers a broader strip per pass than a narrow trimmer, helping reduce passes across lawn edges and open areas. For longer sessions, the included 4Ah battery is rated for up to 63 minutes of runtime. An adjustable handle can be set to the user’s preference, and Turn-To-Edge operation lets the tool switch roles without carrying a separate edger. The stated power increase is intended for cutting through thick grass.

Skip it if you want a specified automatic or bump-feed system; the BLACK+DECKER LST300 lists automatic spool feed.

A strong fit for users who value a longer stated runtime, a 13-inch path, and trimming-to-edging versatility in one kit. The adjustable handle supports personalized positioning, while buyers focused on line-feed details should check that feature before choosing.

#3 · Power Control

3. BLACK+DECKER LST136

• Dimensions L x W: 13"L x 2"W
• Weight: 7.8 lb
• Size: 46.5"L x 13.5"W x 11"H

Best for: Adjustable power for varied weeds.

Why it ranks #3: The 40V kit includes a battery and charger, while its PowerCommand dial lets users prioritize maximum power or runtime.

The LST136’s PowerCommand dial lets you choose maximum power for thick weeds or maximum runtime for longer trimming, matching output to the task. Its 40V battery has a state-of-charge indicator, and the tool converts between trimming and edging, giving buyers useful control over both workload and lawn finish.

POWERDRIVE transmission sends more power from the motor to the cutting string, while the dial lets you favor cutting strength or runtime as conditions change. A 13-inch cutting path covers a useful strip per pass, and the included telescoping pole and auxiliary handle allow adjustment to the user. The kit supplies a 40V battery, fast charger, spool, and guard. Its battery indicator also makes charge status visible during extended yard work.

Skip it if you prioritize the lightest listed handling for edging; the WORX WG163 weighs 5.5 pounds and includes an edger wheel.

A good match for users who face both thick weeds and longer trimming sessions and want to adjust power accordingly. The 13-inch path and included battery kit add versatility, though buyers prioritizing lower listed weight may prefer a lighter tool.

#4 · Edging Versatility

4. WORX WG163

• Dimensions L x W: 44.6"L x 35"W
• Weight: 5.5 lb
• Size: 20V GT 3.0 Trimmer / Edger

Best for: Guided edging on uneven ground.

Why it ranks #4: This 20V, 5.5-pound tool converts between trimming and edging, with a tilting head and rubberized wheels for guided edging.

The WORX WG163’s 90-degree tilting head lets you trim sloped terrain and reach awkward spots, then convert to an edger in seconds. Rubberized wheels guide the edging pass, helping keep lines straighter, while push-button Command Feed releases line when you need it rather than relying on bumping.

For lawn borders, the included edger wheel supports a guided pass, while the tilting head can help reach slopes and difficult corners without changing tools. Command Feed advances line at the push of a button, giving users direct control over line release. The kit lists two batteries, a charger, guard, flower guard, wheel, spool, and spool caps. At 5.5 pounds, the tool is also relatively light for maneuvering around planting areas.

Skip it if you need a wider cutting path for broad areas; the Greenworks ST80L210 has a 16-inch cutting path.

A useful choice for homeowners who edge along sloped borders, flower beds, and awkward corners as well as trim grass. Its wheel and tilting head support controlled work, while the 12-inch format suits detail work better than covering broad areas quickly.

#5 · Brushless Motor

5. Makita XRU23Z

• Dimensions L x W: 8.07"L x 40.28"W
• Weight: 9.2 lb
• Size: 13 in

Best for: Quiet, controlled precision trimming.

Why it ranks #5: Its brushless motor reaches up to 6,000 RPM and offers high/low speed control, but the tool-only listing excludes the battery.

Makita’s brushless motor delivers up to 6,000 RPM, while a variable-speed trigger gives the user control over cutting speed for precision trimming and edging. The high/low button balances power against runtime, and the 18V LXT tool avoids gas, oil mixing, and pull starts; it is supplied without a battery or charger.

The variable-speed trigger helps adapt cutting speed to the area being trimmed, while the high/low button offers a separate choice between power and runtime. Makita specifies up to one hour with an 18V LXT 4.0Ah battery, which is sold separately. The brushless motor and cordless operation avoid oil mixing and pull starts, and the product description cites lower noise and reduced maintenance compared with gas-powered operation.

Skip it if you need a battery and charger included in the kit; the BLACK+DECKER LST136 includes both.

A fit for users already on Makita’s 18V LXT platform who want variable-speed precision and reduced gas-tool upkeep. Remember that the stated hour of runtime requires a separately sold 4.0Ah battery, so kit completeness depends on what you own.

#6

6. Greenworks 40V Combo

• Dimensions L x W: 64.5"L x 7.5"W
• Weight: 16.5 lb
• Size: 40V 12" + 390CFM (2.0Ah)

Best for: Trimming plus driveway cleanup.

Why it ranks #6: The kit pairs a 12-inch string trimmer with a blower and 2.0 Ah battery, making it useful for buyers who need both tools.

This Greenworks kit pairs a 12-inch auto-feed trimmer with a 390 CFM blower, so one battery platform can handle fence-line weeds and post-trimming cleanup. The 40V 2.0Ah battery is listed as compatible with more than 75 Greenworks tools, giving the combo a role beyond the two included yard tools.

The trimmer’s .065-inch auto-feed line is specified to cut weeds up to one inch along fences, helping with growth where a mower cannot reach. After trimming, the blower’s listed 110 mph air speed can clear wet leaves from driveways, avoiding a separate cleanup pass with a rake. The package uses a 40V 2.0Ah battery, which the supplied facts say recharges in 60 minutes and powers over 75 Greenworks tools.

Skip it if you only need a trimmer and want a wider cutting path; the Greenworks ST80L210 has a 16-inch path.

Choose this combo if your routine includes both fence-line trimming and clearing leaves from driveways. Its shared 40V battery platform adds compatibility with other Greenworks tools, while the 12-inch trimmer and 2.0Ah battery are relevant limits for larger jobs.

#7

7. BLACK+DECKER LST300

• Dimensions L x W: 36.23"L x 8.5"W
• Weight: 5.7 lb
• Size: One Size

Best for: Quick trim-and-edge jobs.

Why it ranks #7: This 5.7-pound 20V kit includes a battery and charger, and its 12-inch trimmer converts to a wheeled edger.

The LST300 switches between string trimming and wheeled edging in seconds, letting you finish lawn edges without changing tools. Its 20V battery and charger are included, while the automatic feed spool advances line as needed, so routine trimming does not require bumping the head to release more line.

POWERDRIVE transmission delivers more power from the motor to the cutting string, and the stated 6,200 RPM supports a brisk pace through ordinary overgrowth. The 12-inch cutting width suits edging and general lawn maintenance, while the adjustable handle and lightweight 5.7-pound body help with maneuvering. Automatic line feed removes the need for bumping during use. The kit includes a battery, charger, spool, and guard, so the listed components cover basic setup.

Skip it if you need a wider swath for a large, demanding yard; the Greenworks ST80L210 cuts a 16-inch path.

A practical fit for homeowners who want one cordless tool for trimming and edging around a modest lawn. The included battery and automatic feed simplify setup and use, while the 12-inch cutting width is a consideration for wide, open areas.

#8

8. Kobalt 40V Trimmer

• Dimensions L x W: 38"L x 12"W
• Size: 15-in

Best for: Kobalt 40V platform owners.

Why it ranks #8: Its 15-inch cutting width and 40V platform suit broad trimming, but it is a bare tool with battery and charger sold separately.

The Kobalt 40V Max trimmer’s 15-inch cutting path covers a broad strip per pass, supporting routine lawn-edge and weed trimming without a cord. Its straight-shaft format is listed at 38 inches long, and compatibility with Kobalt 40V Max batteries makes it a straightforward bare-tool option for owners of that platform.

The 15-inch cutting width can reduce the number of passes needed compared with a narrower trimmer, while cordless operation avoids managing a power cord across the yard. The 40V Max battery system is compatible with all Kobalt 40V Max batteries, giving existing platform owners a way to use a battery they already have. This listing is a bare tool: battery and charger are sold separately, so setup depends on owning or acquiring compatible power equipment.

Skip it if you need a complete kit with battery and charger; the BLACK+DECKER LST300 includes both.

A sensible bare-tool choice for Kobalt 40V Max owners who want a 15-inch cordless trimmer for routine yard work. It is less convenient for newcomers to the platform, since the battery and charger must be obtained separately.

#9

9. goodjob 20V Trimmer

• Dimensions L x W: 1"L x 1"W

Best for: Lightweight yard touch-ups.

Why it ranks #9: At a stated 3.5 pounds, it is the lightest listed option and includes two batteries, though its cutting width is not provided.

At 3.5 pounds, the goodjob cordless trimmer keeps the tool light in hand, a useful advantage for quick cleanup around lawns, gardens, patios, and sidewalks. Its 20V battery system supports trimming, edging, and weed clearing, and the package includes two batteries for swapping between them during yard work.

The low listed weight can make repositioning around garden edges and patio boundaries less tiring than handling a heavier tool. Its 20V lithium-ion system is specified for trimming, edging, and clearing weeds, giving it several basic yard-maintenance roles. Two batteries are included, so one can be available while the other is in use; the supplied information does not state their capacity or a runtime. The product details also do not specify cutting width or line-feed method.

Skip it if you need a stated cutting width or runtime before choosing; the BLACK+DECKER LST136 lists a 13-inch path and battery indicator.

Consider it for lighter routine maintenance around a lawn, garden, patio, or sidewalk, especially if low tool weight matters. Buyers who need a defined cutting width, runtime, or feed system should compare those specifications before selecting it.

#10

10. RAXONE 24V Trimmer

• Dimensions L x W: 22.83"L x 8.66"W
• Weight: 6.2 lb
• Size: 8 in

Best for: Multi-task trimming and pruning.

Why it ranks #10: Its 8-inch head and three replaceable blades add versatility, but the blade-based setup is less directly suited to conventional string trimming.

Three replaceable blades give the RAXONE separate options for grass trimming, weed cutting, and shrub pruning, extending its role beyond a conventional string trimmer. The 8-inch cutting width and compact body suit maneuvering around flower beds and trees, while tool-free blade changes let users switch tasks without reaching for a tool.

The 24V high-torque motor is paired with a stated runtime of up to 60 minutes, supporting a range of small yard-maintenance tasks. Its three blades cover grass, weeds, and shrub pruning, and the tool-free replacement system makes changing between those jobs simpler. An 8-inch cutting width favors control around trees and flower beds over covering broad lawns in each pass. The listed package includes two 4,000mAh batteries, and the body folds for storage.

Skip it if you need to clear broad lawn areas in fewer passes; the Greenworks ST80L210 has a 16-inch cutting path.

A fit for gardeners who want one compact tool for grass, weeds, and light shrub pruning around beds and trees. Its foldable body and blade changes suit varied small-yard tasks, but the 8-inch path is a boundary for large open lawns.
