A gas string trimmer runs as long as there’s fuel, swings heavy line through thick weeds and brush, and suits large lots and fence lines. Most use a small two-stroke engine that runs on mixed fuel; a few four-stroke models run on plain gas. Straight shafts reach under shrubs and are better for tall users; curved shafts are lighter and cheaper.
