Yard Edging • Grass Trimming • Battery vs Gas Models
String trimmers—often called weed eaters—are essential lawn maintenance tools used for edging sidewalks, trimming around fences, and cleaning up areas your lawn mower cannot reach. Choosing the right model depends on yard size, terrain, vegetation density, and your preferred power source.
If you're building a complete yard maintenance setup, you may also want to review our Lawn Mower Guide and Leaf Blower Guide.
Types of String Trimmers
Cordless (Battery-Powered)
Cordless trimmers have become the most popular option for homeowners. Modern lithium-ion battery systems provide strong cutting performance while remaining lightweight and quiet.
- Quiet operation
- Low maintenance
- No fuel mixing required
- Compatible with cordless tool ecosystems
Corded Electric
Corded electric trimmers are inexpensive and reliable for small yards where extension cord access is practical. They provide consistent power but limit mobility.
Gas-Powered
Gas trimmers offer the highest cutting power and unlimited runtime. These models are best suited for large properties, dense weeds, and heavy brush clearing.
Straight Shaft vs Curved Shaft
- Straight shaft → Greater reach and better performance on larger properties
- Curved shaft → Lighter weight and easier maneuverability for small yards
Cutting Width Guide
- 10–12 inches → Light trimming and small yards
- 13–15 inches → Typical residential lawn maintenance
- 15+ inches → Large yards and thicker vegetation
Battery Voltage Guide
- 18V–20V → Light-duty trimming
- 36V–40V → Moderate to heavy yard work
- 60V+ → High-performance cordless systems
- Gas equivalent → Large properties and dense growth
Key Features to Look For
- Automatic or bump line feed system
- Adjustable handle and shaft length
- Edging conversion capability
- Lightweight balanced design
- Battery compatibility with other outdoor tools
When to Choose Gas Over Electric
- Large property size
- Heavy brush clearing
- Frequent trimming sessions
- Thick weeds or overgrown vegetation
For heavy debris cleanup after trimming, see our Leaf Blower Guide.
Common Buying Mistakes
- Choosing insufficient cutting width
- Ignoring battery runtime
- Overlooking ergonomics and weight
- Buying gas models for small suburban lawns
Final Recommendation
For most homeowners in 2026, a 40V cordless string trimmer offers the best balance of cutting power, convenience, and low maintenance.
Gas models remain the best option for very large properties, heavy brush clearing, and extended trimming sessions where maximum runtime and power are required.
