- Two included batteries mean a full lot can be edged and trimmed on one charge cycle
- Dual-exit head keeps line closer to hardscape without scalping the lawn
Cons

Best lightweight edger. The WG183's low weight and pivoting head make repetitive edging passes less tiring.
Greenworks 40V 12-Inch Cordless String Trimmer
Greenworks
- ✓12-inch cutting swath
- ✓40V lithium battery, 2.0Ah included
- ✓Pivoting head
- ✓Variable speed trigger

Pros
- Lowest price of the group while still including a pivoting head
- Variable speed trigger helps conserve battery during precision edging
- 3-year warranty covers longer than most trimmers at this price
Cons
- 12-inch swath is the narrowest here, meaning more time on longer edges
- 2.0Ah battery has the shortest runtime in this list
- Pivot mechanism feels less solid than EGO or Worx
Best budget edger. The Greenworks 40V gets the basic pivoting function without the higher price of the premium picks.
Husqvarna 128LD Gas String Trimmer
Husqvarna
- ✓28cc 2-cycle gas engine
- ✓17-inch cutting swath
- ✓Straight shaft with Tap 'n Go head
- ✓Smart Start recoil system
- ✓Air Purge carburetor priming
Pros
- 17-inch swath covers a long driveway edge in fewer passes than any battery model here
- No battery to manage on properties with hundreds of feet of edging
- Straight shaft gives more reach along raised beds and retaining walls
Cons
- No dedicated pivoting edge guide, angle is held manually
- Heavier and louder than the cordless options
- Requires mixed fuel and periodic carburetor maintenance
Best for long runs. The 128LD's reach and power suit large properties with extensive edging, at the cost of convenience.
A trimmer that cuts grass well doesn't automatically edge well. The head has to pivot cleanly to a vertical angle and hold a straight line against concrete without bogging down.
The best string trimmers for edging combine a tool-free pivoting head with enough torque to run the line flush against a driveway or walkway for the length of the job.
In this roundup, the EGO Power+ ST1521S comes out on top for its combination of a clean-locking pivot head and 56V torque that doesn't stall against hard edges.
The Worx WG183 trades some cutting width for a lighter build that's easier to hold at an angle for a long edging pass, and the Greenworks 40V 12-inch gets the same pivoting function at a lower price for occasional use.
For properties with long stretches of driveway or curb, the gas-powered Husqvarna 128LD's 17-inch swath and unlimited runtime cut the job down to fewer passes.
The Best String Trimmers for Edging at a Glance
Best overall: EGO Power+ ST1521S, the strongest combination of pivoting head design and torque for holding a clean vertical line.
Best lightweight: Worx WG183, under 5 pounds with two batteries included for long edging sessions.
Best budget: Greenworks 40V 12-inch, a working pivot head at the lowest price in this list.
Best for large properties: Husqvarna 128LD, a 17-inch gas swath for long driveway and curb runs.
What Makes a Great Edging Trimmer
Pivoting head: a tool-free 90-degree pivot is what turns a lawn trimmer into an edger. Look for firm detents that hold the angle rather than a loose hinge that drifts mid-cut.
Torque at the tip: thinner cutting lines edge more precisely but can bog down against dense turf roots at the edge of concrete. A trimmer with enough motor torque keeps the line spinning at full speed through that resistance.
Weight and balance: edging means holding the trimmer at an angle, often for longer stretches than mowing. A lighter, well-balanced tool is noticeably less fatiguing over a full driveway or sidewalk length.
