Echo SRM-225 Straight-Shaft Gas String Trimmer

Our verdict
For most suburban yards, the EGO 56V POWERLOAD wins on convenience: it starts instantly, runs quiet, self-winds its line, and needs no fuel or tune-ups. Its ~45 min runtime and .095 in line handle typical grass and edging with ease. The Echo SRM-225 pulls ahead only when the job gets big or brutal - a 17 in swath, 21.2cc engine, and refuel-and-go runtime chew through tall weeds and light brush a battery trimmer bogs down in. Choose battery for a tidy lawn and low upkeep; choose gas for large lots, dense growth, or all-day sessions where you don't want to swap packs.
