A strong yard trimmer should match your lawn’s size and growth, with enough cutting width and runtime to finish the work and a power source that suits your setup. The EGO Power+ ST1502SA leads this group with a 15-inch cutting swath, professional-grade 0.095-inch line, a 2.5Ah battery, and up to 45 minutes of runtime. Other picks serve different needs: the Greenworks 80V has a 16-inch path for wider coverage, while the BLACK+DECKER BESTA510 plugs into an outlet and offers a 14-inch path.
This roundup compares cordless kits, a corded trimmer, trimmer-edger combinations, and a blower combo. Check whether a battery and charger are included before choosing, especially if you already own tools from a compatible battery system.
The EGO Power+ ST1502SA is the Best Trimmer For Yard overall in this lineup. Its 15-inch cutting swath and 0.095-inch line suit general lawn trimming, while the included 2.5Ah battery is rated for up to 45 minutes of runtime. A Rapid Reload head makes line changes easier, and variable speed lets you adjust output.
Choose it for a cordless trimmer kit with a useful balance of cutting width and included battery; consider a wider 16-inch model for large areas or a trimmer-edger combo if edging is a priority.

#1 · Best Overall
1. EGO Power+ ST1502SA
- Dimensions L x W: 71.7"L x 12.6"W
- Weight: 7.4 lb
- Size: 15"
Best for: For wider cordless trimming passes.
Why it ranks #1: Its 15-inch swath, 0.095-inch line, included 2.5Ah battery, and up to 45 minutes of runtime make it a well-equipped general-yard kit.
A 15-inch cutting swath paired with professional-grade 0.095-inch line gives the EGO POWER+ ST1502SA a wide path for clearing lawn edges and grass in fewer passes. Its included 56V, 2.5Ah battery is rated for up to 45 minutes of runtime, supporting cordless work without a power cord.
The Rapid Reload head makes replacing line simpler, helping reduce interruption when a spool needs attention during routine yard work. Variable speed lets you match cutting pace to the task, while the 15-inch swath covers a wider strip than a 12-inch tool. The included battery and charger make this a ready-to-use cordless kit, and the stated runtime provides a useful planning boundary for a cleanup session. Consider the 45-minute maximum when estimating larger jobs.

#2 · Longest Runtime
2. CRAFTSMAN CMCST901M1
- Dimensions L x W: 31.72"L x 7.72"W
- Size: 13 in
Best for: For longer cordless trimming sessions.
Why it ranks #2: The 13-inch cordless trimmer-edger kit includes a 4Ah battery and claims up to 63 minutes of runtime for longer trimming sessions.
Up to 63 minutes of stated runtime from its included 4Ah battery gives the CRAFTSMAN V20 kit a useful edge for longer trimming sessions. Its 13-inch cutting swath and turn-to-edger operation let you handle lawn passes and border work with the same cordless tool.
The 13-inch swath covers a wider area per pass than a 12-inch trimmer, while the adjustable handle lets you set a more comfortable working position. CRAFTSMAN states 52% more power for tackling thick grass, and the included charger and 4Ah battery make this a complete kit. The turn-to-edger feature supports switching tasks without changing tools. Runtime is listed as up to 63 minutes, so actual work planning should account for that being a maximum.
- Up to 63 minutes of stated runtime
- 13-inch cutting swath
- Adjustable handle
- Turns from trimmer to edger
- Its 13-inch cutting path is narrower than the Greenworks ST80L210’s 16-inch path.
Skip it if you need a wider pass across a large lawn; the Greenworks ST80L210 has a 16-inch cutting path.
The CMCST901M1 suits homeowners who want a longer stated runtime, adjustable handling, and edging capability in one cordless kit. Its 13-inch swath is a fit consideration for buyers covering especially broad open areas.

#3 · Widest Cutting Path
3. 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: For demanding, wide-area trimming.
Why it ranks #3: Its 16-inch path and .080-inch dual line suit wider areas, while the 80V platform is specified for demanding yard maintenance.
A 16-inch cutting path with .080-inch dual line makes the Greenworks ST80L210 a strong match for covering wide areas and demanding grass cleanup. Its 80V battery platform supplies cordless power, while bump-feed line advancement lets you add line during work without stopping for a separate adjustment.
The wider path can reduce the number of passes across an open lawn compared with a narrower trimmer, and the dual-line setup is specified for efficient trimming and cleaner cuts. Greenworks identifies the 80V platform as suited to tough grass, weeds, and demanding yard maintenance. The bump-feed head supports quick line advancement during a session. This kit includes a 2Ah battery and charger, so it arrives with the components needed for cordless operation rather than being a bare tool.
- 16-inch cutting path
- .080-inch dual line
- 80V platform for demanding yard maintenance
- Bump-feed head advances line during trimming
- The 16-inch cordless kit weighs 16 pounds as listed.
Skip it if you prioritize a lighter listed tool for handling; the BLACK+DECKER BESTA510 weighs 6.3 pounds and has a 14-inch path.
Choose the ST80L210 for larger lawns and tougher grass where a wide dual-line path is useful. Its 16-pound listed weight is important to consider if you prioritize carrying and maneuvering ease.

#4 · Best Trimmer-Edger
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: For edging and sloped lawns.
Why it ranks #4: This 5.5-pound 20V tool converts between trimming and edging, includes two batteries, and has a tilting head and guiding wheels.
A tool-free conversion from string trimmer to edger makes the WORX WG163 useful when one yard-care pass includes both grass cleanup and crisp borders. Its head tilts 90 degrees for sloped terrain and hard-to-reach spots, while rubberized wheels help guide the edging cut along a straighter line.
The push-button Command Feed advances line when you need it, so you can resume trimming without bumping the head. Switching between trimming and edging takes seconds, avoiding the need to store a separate edger. The 90-degree tilting head helps reach awkward angles, and the rubberized wheels support steadier edging. The listed package includes two batteries, a charger, an edger wheel, and spool components, giving you key parts for cordless yard work and line management.
- Converts between trimmer and edger in seconds
- Push-button feed advances line on demand
- 90-degree tilting head reaches slopes and awkward spots
- Rubberized wheels guide straighter edging cuts
- The cutting path is 12 inches, narrower than the 15-inch EGO ST1502SA.
Skip it if you want a wider 15-inch cutting path; the EGO Power+ ST1502SA offers that broader swath.
Choose the WG163 for a yard where edging, trimming, and sloped areas all matter, especially if you want one cordless tool for both jobs. Its 12-inch path is a boundary to weigh for wider lawns.

5. BLACK+DECKER LST300
- Dimensions L x W: 36.23"L x 8.5"W
- Weight: 5.7 lb
- Size: One Size
Best for: For lightweight trimming and edging.
Why it ranks #5: The cordless 12-inch trimmer converts to an edger and includes a battery and charger, making it a convenient kit for routine yard edges.
At a listed 5.7 pounds, the BLACK+DECKER LST300 is a lightweight cordless option that converts from trimming to edging in seconds. Its 12-inch cutting width, included 20V battery and charger, and automatic feed spool make it a practical kit for routine lawn borders and grass cleanup.
POWERDRIVE transmission delivers more power from the motor to the cutting string, with a stated 6,200 RPM, supporting quicker work through weeds and overgrowth. Automatic Feed Spool supplies line as needed without bumping, reducing interruptions while trimming. Switching to edger mode lets you finish borders with the same tool. The adjustable handle supports a customized grip, and the included battery and charger mean there is no separate kit purchase required for cordless operation.
- Listed weight of 5.7 pounds
- Converts between trimmer and edger
- Automatic Feed Spool advances line without bumping
- Includes 20V battery and charger
- Its 12-inch cutting path is narrower than the BLACK+DECKER BESTA510’s 14-inch path.
Skip it if you want a wider path for covering ground in fewer passes; the BLACK+DECKER BESTA510 has a 14-inch cutting width.
The LST300 suits homeowners seeking a lightweight cordless tool for ordinary trimming and edging, with battery and charger included. Its 12-inch path is a sensible boundary to weigh for larger open lawns.

#6 · Best Blower Combo
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: For trimming plus leaf cleanup.
Why it ranks #6: The kit pairs a 12-inch trimmer with a 390 CFM blower and 2.0Ah battery, covering trimming and debris cleanup in one package.
A combo package pairs Greenworks’ 12-inch string trimmer with a 390 CFM blower, letting you trim lawn edges and then clear debris without switching to a separate yard tool. The included 40V, 2.0Ah battery supports both tools, and the platform is compatible with more than 75 Greenworks tools.
The trimmer’s 12-inch cutting width suits edging and routine grass cleanup, while the blower adds a second task to the same kit for driveway clearing. Supplied product facts say the battery powers 75-plus tools and recharges in 60 minutes, which can make the battery useful beyond this combo. The kit weighs 16.5 pounds as listed, so consider handling and storage for the complete set, not just the trimmer.
- Includes a 12-inch string trimmer and 390 CFM blower
- One 40V, 2.0Ah battery powers the combo
- Battery works with more than 75 Greenworks tools
- Battery recharge time is listed as 60 minutes
- The listed trimmer cutting path is 12 inches, smaller than Greenworks’ 16-inch 80V ST80L210.
Skip it if you need a wider cutting path for broad lawn passes; the Greenworks ST80L210 has a 16-inch path.
This combo fits homeowners who want trimming and blower cleanup in one battery-powered package, with a battery platform that extends across Greenworks tools. The 12-inch trimmer path is a practical limit for large open areas.

7. BLACK+DECKER BESTA510
- Dimensions L x W: 8.5"L x 4.88"W
- Weight: 6.3 lb
- Size: One Size
Best for: For corded trimming and edging.
Why it ranks #7: Its 6.5-amp motor, 14-inch path, automatic line feed, and wheeled edging guide suit buyers who prefer an outlet-powered tool.
A 14-inch cutting path and 6.5-amp motor give the BLACK+DECKER BESTA510 a broad pass for corded yard cleanup, while its rotating design converts the tool into a wheeled edger. Automatic Feed Spool advances line without bumping, helping keep work moving through grass and weeds.
POWERDRIVE transmission works with the 6.5-amp motor to tackle tough weeds, grass, and overgrowth, according to the supplied product details. The 14-inch path can cover more ground per pass than a narrower trimmer, and the wheeled edge guide supports finishing borders around driveways, sidewalks, and flower beds. Automatic line feeding removes the need to bump the head for line advancement. Its electric design is the key fit consideration for your yard setup.
- 14-inch cutting path
- 6.5-amp motor with POWERDRIVE transmission
- Rotates from trimmer to wheeled edger
- Automatic Feed Spool advances line without bumping
- Its corded electric design requires access to a power connection while working.
Skip it if you need cordless freedom across a large yard; the EGO Power+ ST1502SA includes a battery and charger.
Pick the BESTA510 for a yard with accessible power and a mix of grass trimming and defined borders. The wheeled guide and automatic feed simplify those tasks, but the corded setup limits where you can work.

8. DEWALT DCST922B
- Dimensions L x W: 39"L x 10"W
- Weight: 7.3 lb
- Size: 14 in
Best for: For compact storage and portability.
Why it ranks #8: The 14-inch brushless trimmer folds to reduce its length by 40%, but this listing is a bare tool without an included battery or charger.
A folding hinge reduces the DEWALT DCST922B’s length by 40%, making it easier to store or transport when garage space and portability matter. It still offers a 14-inch cutting swath, and its variable-speed trigger provides control over cutting pace during yard work.
The QuickLoad Spool is specified for fast, easy replacement of 0.080-inch line, helping simplify a routine maintenance step. A 14-inch path supports broader passes than a compact 12-inch trimmer, while the folding hinge reduces tool length for storage and transport. This listing is for the bare tool, so buyers need to account for the battery and charger separately if they do not already have compatible equipment. The 20V MAX system includes more than 250 tools, according to supplied facts.
- Folding hinge reduces length by 40%
- 14-inch cutting swath
- QuickLoad Spool for 0.080-inch line
- Variable-speed trigger
- It is a bare tool, with no battery or charger included.
Skip it if you need a complete kit with battery and charger; the EGO Power+ ST1502SA includes both.
The DCST922B is a fit for DEWALT 20V MAX users who value compact storage, portability, and adjustable speed. Its bare-tool format is the key boundary for buyers who need a battery and charger included.

9. WeGofly WEG21T
- Dimensions L x W: 33"L x 8"W
- Size: 13-Inch
Best for: For multi-function yard maintenance.
Why it ranks #9: Its 13-inch four-in-one design and two 21V 6.0Ah batteries offer versatility, though the supplied details do not state runtime or cutting-line size.
Four working modes—string trimmer, lawn edger, mini lawn mower, and brush cutter—make the WeGofly WEG21T a versatile option when yard tasks vary beyond routine grass trimming. Its 13-inch format and included pair of 21V, 6.0Ah batteries support a kit approach to several kinds of garden cleanup.
The different tool modes let you switch the type of yard work handled by one device, from edging borders to cutting small shrubs, as described in the supplied facts. Two 6.0Ah batteries and a matched charger are included to support extended use without relying on a single battery. The listed weight is 5.2 pounds, a useful consideration when moving among tasks. A storage bag is provided for accessories, screws, and blades, helping keep changeover parts together after use.
- Four modes: trimmer, edger, mini mower, and brush cutter
- Includes two 21V, 6.0Ah batteries and charger
- Listed weight is 5.2 pounds
- Storage bag holds accessories, screws, and blades
- A 13-inch cutting path is narrower than Greenworks’ 16-inch ST80L210.
Skip it if you want the wider 16-inch path for large open areas; the Greenworks ST80L210 is listed with that cutting width.
Choose the WEG21T if you value one kit for trimming, edging, small-area mowing, and brush-cutting tasks. Its included storage bag helps organize accessories, while its 13-inch path is a consideration for broad lawns.

10. KOMASTY 20V Trimmer
- Dimensions L x W: 40"L x 8"W
- Size: 12 in
Best for: For compact-space storage.
Why it ranks #10: The folding shaft and adjustable head help with storage and reach, but the product is specified for regular lawn grass rather than thick or overgrown growth.
A shaft that folds 180 degrees in three ways gives the KOMASTY cordless trimmer a storage advantage for crowded garages and tight corners. Its 90-degree adjustable head and 180-degree rotating handle also help position the 12-inch cutter for slopes, under benches, and other awkward garden areas.
The folding shaft can reduce the space needed to put the tool away, a practical benefit when storage is limited. During trimming, the adjustable head and rotating handle offer different working angles for reaching under benches or along slopes. The product is specified for regular lawn maintenance, and supplied facts caution against excessively thick, wet, or overgrown grass. That limitation makes it better suited to upkeep than heavy clearing. Two 2.0Ah batteries and a charger are included.
- Shaft folds 180 degrees in three ways
- 90-degree adjustable head
- 180-degree rotatable handle
- Includes two 2.0Ah batteries and charger
- It is intended for regular lawn grass, not excessively thick, wet, or overgrown grass.
Skip it if you routinely clear thick or overgrown grass; the EGO Power+ ST1502SA lists professional-grade 0.095-inch line for yard cleanup.
The KOMASTY fits gardeners who need a trimmer that stores compactly and can angle into awkward spots. Keep its stated regular-grass use in mind if your property needs frequent heavy-duty weed clearing.

View on AmazonAvoid the line-feed and cutting-load mismatch
Frequent line breaks or slow progress can come from asking a light-duty trimmer to handle growth it was not designed for. The KOMASTY 20V Trimmer is described for maintaining regular lawn grass, and its product details caution against excessively thick, wet, or overgrown grass. By contrast, the Greenworks 80V Trimmer is positioned for demanding yard work and uses a 16-inch path with .080-inch dual line.
That does not guarantee it will handle every brush or weed, but it gives a clearer basis for choosing between routine grass trimming and heavier work. Line systems also differ: the WORX WG163 uses a push-button Command Feed, the BLACK+DECKER BESTA510 has automatic feed, and the Greenworks 80V Trimmer uses bump feed.
Pick a feed style you are comfortable operating, and keep hands and feet clear of the cutting line while working.
Check the battery-system and kit details
A cordless tool listing may not include the equipment needed to start trimming, so verify the package contents and battery platform before deciding. The DEWALT DCST922B is explicitly a bare tool, even though it uses DEWALT’s 20V MAX system; it is a practical choice primarily for someone who already has a compatible battery and charger. The EGO Power+ ST1502SA, WORX WG163, and BLACK+DECKER LST300 list batteries and chargers in their included components.
Another potential trap is assuming that batteries from tools with similar voltage are interchangeable: the Greenworks 40V combo and Greenworks 80V Trimmer use different voltage platforms. Greenworks says the 40V battery powers 75-plus tools, but that statement does not make it compatible with the 80V model.
Match the exact platform and check the kit contents rather than relying on brand or voltage resemblance.
How to Choose a Yard String Trimmer
Cutting width and line
Look for a cutting path suited to how much ground you cover and how much trimming you do around obstacles. The listed models range from 12 inches on the WORX WG163 and BLACK+DECKER LST300 to 16 inches on the Greenworks 80V Trimmer; the EGO Power+ ST1502SA offers a 15-inch path and 0.095-inch line, while the Greenworks 80V uses .080-inch dual line. A wider path can cover more ground per pass, while a narrower tool may be easier to guide around beds and tight edges.
Choose the wider end for broad lawns and the 12- to 14-inch range for smaller or more intricate areas. Cutting width alone does not establish how well a tool handles heavy brush.
Power source and battery kit
Choose a power source that fits your yard layout and check whether the battery and charger are included. The BLACK+DECKER BESTA510 is a 6.5-amp corded model, while cordless options include 20V, 40V, 56V, and 80V systems. The EGO Power+ ST1502SA includes a 56V 2.5Ah battery and charger; the Greenworks 40V combo includes a 2.0Ah battery, and the DEWALT DCST922B is a bare tool.
An outlet-powered model may suit a yard where a cord can reach the work area; cordless kits avoid that tether. If you already own battery tools, the matching platform can be useful, but confirm compatibility and included components before buying.
Runtime, weight, and storage
Balance time between charges against the tool’s weight and how easily you can store it. The CRAFTSMAN CMCST901M1 lists up to 63 minutes of runtime with its 4Ah battery, while the EGO Power+ ST1502SA lists up to 45 minutes with a 2.5Ah battery. The WORX WG163 weighs 5.5 pounds and the BLACK+DECKER LST300 weighs 5.7 pounds; the Greenworks 80V Trimmer is listed at 16 pounds.
For longer sessions, stated runtime can help narrow options, though actual results are not supplied. If carrying comfort matters most, favor a lighter listed model; if garage space is tight, the DEWALT DCST922B folding hinge reduces tool length by 40%, and the KOMASTY shaft folds for storage.
Which Yard Trimmer Should You Choose?
For a versatile cordless kit for routine yard care, choose the EGO Power+ ST1502SA: it combines a 15-inch path, included battery and charger, and up to 45 minutes of runtime. If longer stated runtime matters, the CRAFTSMAN CMCST901M1 lists up to 63 minutes and also converts to an edger. For wider coverage and demanding grass, consider the Greenworks 80V Trimmer with its 16-inch dual-line path.
Choose the WORX WG163 if you want a lightweight trimmer-edger with two batteries, or the BLACK+DECKER BESTA510 if you want corded power and a wheeled edging guide. For storage, the DEWALT DCST922B folds, but requires a separate compatible battery and charger.
Match the tool’s stated use and included kit to your yard rather than assuming every trimmer suits heavy weeds.

Frequently Asked Questions
How long should a cordless trimmer battery last for a typical yard?
For a typical yard, look for enough runtime to finish trimming without needing a recharge; the right amount depends on yard size and how demanding the work is. In this lineup, the EGO kit lists up to 45 minutes, while the CRAFTSMAN kit lists up to 63 minutes. Actual runtime can vary with use.
Can I use a string trimmer to cut thick weeds or brush?
A string trimmer can handle routine grass and lighter weeds, but suitability for thick weeds or brush depends on the tool and its stated use. Do not assume every model in this lineup is intended for heavy growth. For demanding grass, the Greenworks 80V model is listed with a 16-inch dual-line path.
Is a corded or cordless trimmer better for my yard layout?
A cordless trimmer avoids a power cord across the yard, which can suit layouts with distant or separated areas; check whether its battery and charger are included. A corded model may suit work near an outlet. The BLACK+DECKER BESTA510 is corded, while the listed cordless kits vary in included batteries.
What should I look for if edging is a priority?
Choose a model explicitly described as converting to an edger or as a trimmer-edger combo. Several lineup options offer that function, including the WORX WG163 and CRAFTSMAN CMCST901M1. The EGO is the overall pick for routine trimming, but a combo may be a better match when edging matters most.
What should I check before choosing a cordless trimmer kit?
Check what comes in the box, especially the battery and charger, and compare the stated runtime with your yard’s needs. The EGO kit includes a 2.5Ah battery and charger, while the DEWALT DCST922B is a bare tool requiring a separate compatible battery and charger. Confirm the kit details before choosing.
Final Words
For routine yard care, the EGO Power+ ST1502SA is the balanced overall choice, with a 15-inch cutting path, included battery and charger, and up to 45 minutes of stated runtime. If longer stated runtime or edging matters more, consider the CRAFTSMAN; choose Greenworks 80V for a wider path. For corded use, look at the BLACK+DECKER BESTA510.
Match the included kit and stated use to your yard, especially if you expect heavy weeds.
