I tested a range of corded, cordless, and handheld trimmers to find the most useful tools for edging, trimming, and dethatching yards of different sizes and needs.
I spent time using every tool in this roundup so I could recommend the right trimmer for common yard tasks—from tight edging and small hedges to dethatching and cordless convenience.
My selection focuses on usability, real-world power, and features that actually matter: cut width, motor strength, line-feed systems, battery kit completeness, and ergonomic touches that reduce fatigue.
I compared these tools by power source (corded vs cordless), cutting width or blade length, ease of switching modes (trimmer/edger/minimower), and practical features like automatic line feed, cord retention, bag capacity, and handle ergonomics.
1. BLACK+DECKER 14-Inch Corded String Trimmer & Edger – Best Value Corded Trimmer
I rely on this lightweight corded trimmer when I want straightforward power and fast edging without battery hassles.
Why I picked it: Powerful corded motor, automatic spool feed, and wheeled edging in a very practical package.
Best for: Small to mid-size yards that need reliable corded power and easy edging.
A very affordable corded option compared with battery systems.
Pros
- Strong 6.5-amp motor
- Automatic spool feed—no bumping
- Quick trimmer-to-edger conversion
- Lightweight and adjustable
Cons
- Cord limits range
- Not for very heavy brush
My take
I used this BLACK+DECKER as my go-to corded trimmer when I wanted simple, continuous power. The 6.5-amp motor chews through thick grass and common weeds more confidently than you’d expect from a lightweight unit.
The auto-feed spool makes a real difference in forward progress—I didn’t have to stop to bump or re-feed, which keeps the job moving. Switching to the wheeled edge guide is quick and gives a neat, consistent border along sidewalks.
Because it’s corded I never worried about battery life, and the cord-retention feature kept the plug secure while I worked. For anyone wanting solid performance without the complexity of batteries, this is my practical choice.
2. Sun Joe AJ801E Dethatcher & Scarifier – Best for Dethatching & Scarifying
I reach for this Sun Joe when my lawn needs a quick dethatch or a scarify to encourage new growth.
Why I picked it: 12-amp motor with scarifier attachment and adjustable depth control for real lawn rejuvenation.
Best for: Homeowners tackling compacted or thatch-heavy lawns who want an affordable dethatching tool.
A budget-friendly alternative to renting a commercial dethatcher.
Pros
- Powerful 12-amp motor
- Five depth settings
- Scarifier and dethatcher functions
- Detachable collection bag
Cons
- Collection bag fills quickly
- Lightweight chassis limits large jobs
My take
When I needed to remove embedded thatch and improve airflow to the roots, the Sun Joe AJ801E handled the job. The 12-amp motor gives this compact machine surprising bite.
I appreciated the five-position height adjustment—being able to control depth matters when I switch from light dethatching to deeper scarifying for overseeding prep. The included scarifier blade is a real advantage for prepping stubborn areas.
The 8-gallon bag collects debris cleanly but does fill often on heavy jobs, so I plan short passes and quick empties. For a homeowner who wants to maintain lawn health without renting equipment, this is the unit I keep handy.
3. BLACK+DECKER 17-Inch Corded Hedge Trimmer – Best Compact Hedge Trimmer
I use this for small hedges and tight shrub work where a lightweight, low-vibration tool matters more than sheer blade length.
Why I picked it: Dual-action blades and a compact form that reduces vibration and fatigue during shaping.
Best for: Small hedges, shrubs, and users who prefer corded tools over battery replacements.
An inexpensive, dependable corded hedge trimmer.
Pros
- Dual-action hardened steel blade
- Reduced vibration
- Lightweight and easy to handle
- Secure cord retention
Cons
- Not for very thick branches
- Requires extension cord
My take
I picked this 17-inch trimmer when I wanted cleaner cuts without arm-shaking vibration. The dual-action blade gives a smoother, more controlled cut than single-blade models.
The built-in T-handle and full-length trigger help me keep precise control around decorative plants and narrow hedges. It reliably handled branches up to roughly 5/8 inch, which is perfect for routine maintenance.
If you want a fuss-free corded tool for lighter hedge work, this is the compact option I reach for first.
4. Sun Joe 7.2V Cordless Grass Shears & Trimmer – Best for Small Jobs & Tight Spaces
I keep this Sun Joe in my tool closet for quick touch-ups, flower-bed edges, and delicate trimming that a bigger tool would damage.
Why I picked it: 2-in-1 blades, very light weight, and cordless convenience make precise small-area work painless.
Best for: Garden beds, edging around plantings, and anyone who dislikes lugging a cord.
A low-cost handheld solution for precise tidying.
Pros
- Cordless and ultra-lightweight
- Converts between grass and hedge blades
- Easy to maneuver in tight areas
- Includes battery and charger
Cons
- Limited power for thick branches
- Smaller blade for fine work only
My take
This Sun Joe is my go-to for edging flower beds and trimming around delicate plantings. The tool’s 2.8-pound design makes awkward angles easy and keeps my shoulders from tiring.
Switching between the 4-inch grass shears and the 6-inch hedge blade is simple and useful when I need both precision and small-scale trimming in a single session. I’ve owned several Sun Joe products and find their handheld tools dependable for light tasks.
Battery life has surprised me—long enough for multiple small jobs—and the included charger keeps it ready. For quick cleanup and fine shaping, I prefer this to hauling a larger trimmer out.
5. WORX WG170 20V Cordless Trimmer & Mini Mower – Best Cordless Kit with Batteries
I reach for the WORX when I want cordless flexibility plus the convenience of two batteries and a mini-mower mode for tight strips.
Why I picked it: Two-battery kit, 3-in-1 versatility, and a lightweight design that still gives a respectable runtime.
Best for: Small to mid-size yards where cordless freedom and included batteries matter.
A mid-range cordless package with two batteries included.
Pros
- Includes two batteries and charger
- Transforms into mini mower and edger
- Lightweight at around 5.5 lbs
- Push-button fresh-line feed
Cons
- Batteries take hours to recharge
- Average single-battery runtime
My take
I like the WORX for the way it balances convenience with capability. Having two batteries in the box means I can swap and finish a medium job without waiting for a recharge.
The 3-in-1 flexibility—trimmer, edger, and mini-mower—lets me handle detail strips that my mower misses. The command-feed button is simple and avoids the headaches of bump-feed heads.
Battery life is fine for quarter-acre jobs when I manage passes and swaps; if you plan to do extensive acreage in one go, bring a charging plan. Overall, this is the cordless kit I recommend when you want a full package out of the box.
6. BLACK+DECKER 13-Inch Corded String Trimmer/Edger – Best Lightweight Corded Edger
I use this model when I want a very light, maneuverable corded trimmer that still handles a good trimming radius.
Why I picked it: Automatic spool feed and PowerDrive transmission deliver punch without weight.
Best for: Users who want a very lightweight corded trimmer with easy edging capability.
A cost-effective corded trimmer for occasional use.
Pros
- Automatic spool feed
- PowerDrive for extra torque
- Converts to wheeled edger
- Easy to handle
Cons
- Cord limits large properties
- Smaller cut radius than larger models
My take
I appreciate how light this BLACK+DECKER feels in my hands—it makes edging and trimming up close much less tiring than heavier battery units.
The automatic spool feed saves time and fiddling, and the PowerDrive transmission gives the string more cutting torque than you'd expect from a compact 13-inch head. For quick jobs and tight spots, it performs reliably.
If you prefer not to deal with batteries and want a simple plug-in tool that gets work done, this is the compact choice I recommend.
7. BLACK+DECKER 22-Inch Corded Hedge Trimmer – Best for Large Hedges
I pick this longer-blade trimmer when I need to cover big hedges faster while keeping vibration low.
Why I picked it: Long dual-action blade and a robust motor reduce work time on long hedges.
Best for: Homeowners with larger hedges who want faster progress on lengthy shaping jobs.
A practical corded option for heavier hedge work.
Pros
- 22-inch dual-action blade
- Cuts branches up to 3/4 inch
- Reduced vibration
- Full wraparound handle
Cons
- Heavier than smaller models
- May need rest breaks on long jobs
My take
When I need to tackle long runs of hedges, the 22-inch blade on this BLACK+DECKER pays off—my trimming time drops significantly compared with shorter tools.
The dual-action steel blade smooths cuts and keeps vibration down, which matters when I'm up higher or working longer stretches. The full wraparound handle gives me control for shaping and finishing.
It’s heavier than compact trimmers so I plan breaks for bigger jobs, but for raw hedge coverage this is the tool I rely on.
How I Choose a Trimmer for the Job
Power source: corded vs cordless vs handheld
I decide first whether I want corded continuous power, cordless mobility, or a small handheld for precision. Corded units give steady torque and unlimited runtime; cordless models buy you range and convenience; handhelds are perfect for tight spaces and delicate work.
- Choose corded for long runtime and stronger continuous power.
- Choose cordless for mobility and battery kit convenience.
- Choose handheld for fine edging and small-area trimming.
Cut width, blade length, and motor
I match cut width and blade length to the job: wider heads and longer blades cover more ground, while smaller heads and shear blades give control. Motor amps (corded) and battery voltage (cordless) indicate how well the tool will handle thick growth.
- 14-inch or 13-inch trimmers strike a balance for yards.
- 17–22 inch blades are better for hedge coverage.
- Higher amp motors or included battery packs help with tougher vegetation.
Useful features I look for
Automatic line feed, cord retention, adjustable handles, and multi-mode conversions are features that actually save me time and effort in the yard.
- Automatic spool or command-feed reduces interruptions.
- Cord retention prevents accidental unplugging on corded models.
- Multi-mode tools that convert to edgers or mini-mowers add value.
Maintenance and practical considerations
I consider ease of line replacement, blade sharpening or replacement, and storage. For dethatchers, bag capacity and the need for frequent emptying shape how I plan the work.
Also, think about ergonomics—lightweight tools reduce fatigue, but heavier tools often mean more cutting power.
- Keep spare trimmer spools and extension cords on hand.
- Empty dethatcher bags frequently for best performance.
- Match tool weight to how long you’ll use it in one session.
Frequently Asked Questions
Corded or cordless—how should I choose?
I pick corded when I want constant power and unlimited runtime; I choose cordless for mobility and quick access without running an extension cord. For larger properties, cordless kits with two batteries are the practical middle ground.
How often should I dethatch my lawn?
I usually dethatch every 1–3 years depending on thatch buildup; if roots look matted and water doesn’t penetrate easily, I schedule a dethatching session before overseeding.
What maintenance does a string trimmer need?
I keep spare line spools, clean the guard area after use, inspect the cord retention or battery contacts, and replace worn blades or spool parts to maintain cutting performance.
Can I use electric trimmers on wet grass?
I avoid trimming in heavy rain or with thoroughly soaked grass—wet conditions can clog line heads and risk electric components. A slightly damp lawn is manageable, but I take extra care with corded connections and extension cords.
Final Take
I recommend choosing the trimmer that matches the work you do most often: corded models for steady power, cordless kits for flexibility, and handheld shears for precision.
Each tool here earned a spot because it solves a common yard problem in a practical, reliable way. Pick the one that fits your yard size, favorite features, and how much hands-on maintenance you want to do.
