Grass Trimmer Guide: Corded, Cordless, or Gas—Which Fits Your Yard?

String trimmers (weed whackers) handle edges, tight spots, and light brush that mowers miss. Three power platforms—each with a distinct sweet spot.

Corded Electric

• Pros: Light, quiet, unlimited run time, cheapest.
• Cons: Cord management (extension cords, GFCI). Range limited to ~100 ft.
• Best for: Small–medium yards, outlets accessible.

Cordless (Battery)

• Pros: No cord, quiet, instant start, interchangeable batteries (often same platform as drill/blower).
• Cons: 30–60 min runtime. 7–12 hr recharge (Li-ion: 3–5 hr). Higher upfront cost.
• Best for: Medium yards, obstacle-rich areas, users with compatible battery ecosystem.

Gas (2-stroke / 4-stroke)

• Pros: Maximum power, unlimited range, cuts thick brush/saplings.
• Cons: Heavy, loud, vibration, fuel mixing (2-stroke), maintenance, emissions.
• Best for: Large properties, heavy weeds, professional use.

Cutting Head Options

• Bump-feed line: Standard. Tap to advance.
• Fixed-line / blade: Heavy brush. Metal blades = danger (kickback, thrown debris).

Safety & Ergonomics

• Eye/ear protection, long pants, boots.
• Straight shaft > curved (better reach, less fatigue).
• Shoulder strap for gas/cordless.
• Never remove guard.
