String Trimmer Buying Guide: How to Choose the Best Weed Eater

Get a Clean Edge Every Time

A string trimmer (also called a weed eater or weed whacker) is one of the most-used tools in any yard maintenance kit. It handles the edging, trimming, and detail work that a lawn mower can't reach. Here's how to choose the right one for your property.

Gas vs. Battery String Trimmers

Gas String Trimmers

Gas-powered trimmers deliver the most cutting power and are the go-to for large properties, thick weeds, and extended professional use. They require fuel and periodic maintenance but are unmatched for demanding applications.

Battery (Cordless) String Trimmers

Battery string trimmers have become incredibly capable. Modern 40V and higher models handle most residential yards with ease — they're quieter, lighter, and require zero fuel management. Many Husqvarna battery trimmers share batteries with other tools in the same platform, offering excellent value.

Key Factors to Consider

Power source: Gas for heavy-duty/commercial use; battery for most homeowners.
Cutting width (swath): Wider swaths (15–18") cover more area per pass; narrower (12–14") for precision work.
Line diameter: Thicker line handles tougher weeds; standard 0.080–0.095" works for most lawns.
Bump feed vs. automatic feed: Bump-feed advances line on demand; automatic feed self-adjusts.
Straight shaft vs. curved shaft: Straight-shaft models reach under obstacles better and suit taller users; curved-shaft models are more manoeuvrable for light trimming.
Attachments: Some models accept interchangeable attachments (edgers, cultivators, hedge trimmers) for multi-tool versatility.

String Trimmer or Edger: Do You Need Both?

A good string trimmer can double as an edger when tilted on its side — many users get by with just one tool. If you have long paved borders or formal garden beds, a dedicated edger gives cleaner results. Look for models with an edging guide or built-in edge function.
