String Trimmers compared

A battery string trimmer edges and trims the yard with no gas, no pull cord and much less noise. Here is every major brand at the same tier, side by side, from each brand's own spec pages.

Manufacturer-published specs. Not our tests. Copied from each brand's own product pages, accessed 2026-10-29. We never rank them or pick a winner from specs.

Entry / DIY

Weekend projects, repairs around the house, a few jobs a month. Lighter and lower cost.

Pro / flagship

Daily use, bigger bits and blades, tougher material. More power, usually more weight and cost.

Pick your battery first

Batteries only fit tools from their own brand line. If you already own batteries, compare inside that brand first.

Brands publish weight on different bases: tool only, with a battery (which battery varies), or unstated ("Assembled Product Weight", "Product Weight"). Each bar is tagged with its basis. Only compare bars that carry the same tag.

What the specs mean

Cutting swath

How wide a path it cuts in one pass. Wider means fewer passes.

Max line diameter

Thicker line cuts thicker weeds and lasts longer.

Max speed (RPM)

Head speed with no load.

How to read these tables

  • Values are copied as published. Nothing is estimated, averaged or converted. "not published" means the manufacturer page didn't list it. Bars are in fixed alphabetical brand order. There's no ranking and no winner.
  • Brands publish weight on different bases: tool only, with a battery (which battery varies), or unstated ("Assembled Product Weight", "Product Weight"). Each bar is tagged with its basis. Only compare bars that carry the same tag.
  • Length bases differ (overall length, tool-head length, or a plain 'Length' field). Each bar is tagged. Assembled or package-style dimensions aren't charted.
  • Grey text under a value shows where on the page it came from (if not the spec table), or that the brand doesn't say what the weight includes.
