Echo SRM-310
2-Stroke
The Echo SRM-310 is a 30.5cc <!-- verify: echo-usa.com --> 2-stroke straight-shaft trimmer and the most powerful model in Echo's commercial SRM lineup, built for the most demanding vegetation management — dense brush, saplings, and heavy perennial growth with rigid blade attachments. Under daily commercial production use, monthly fuel system service, gearhead repacking every 25–50 hours, and air filter maintenance after each shift in high-debris environments are routine. The SRM-310's displacement makes it a dedicated clearing tool rather than a standard grass trimmer; pairing it with the correct rigid blade for the vegetation type is important.
