Our take on the Echo 16 in. 21.2 cc Straight Shaft String Trimmer

The Echo SRM-225 is a gas straight-shaft string trimmer with a 21.2 cc two-stroke engine making 1.1 hp. Its i-30 starting system cuts pull effort, and the Speed-Feed 400 head lets you reload line without taking the spool apart. It is a homeowner and light-commercial tool, heavier than battery trimmers but with no cord or charge time. Against battery rivals it trades convenience for unlimited runtime and more torque; against cheaper gas trimmers it is known for easier starts and a durable straight shaft.

Questions and answers

Is the Echo SRM-225 good for a large yard?
Yes. Its gas engine runs as long as you refuel, so it suits big lots and long sessions better than battery trimmers with limited runtime.
How does it compare with a battery trimmer?
It has more torque and no charge time, but it is heavier, louder and needs fuel mixing. Battery trimmers are quieter and lighter but limited by run time.
What line size does it take?
It uses 0.095 in trimmer line in the Speed-Feed 400 head, which reloads without disassembling the spool.
Does it accept attachments?
It is not a split-shaft unit, but Echo lists it as compatible with Pro Attachment Series attachments. Check the specific attachment before buying.
What is included in the box?
The trimmer comes with no additional tools or attachments. Fuel, oil and line are not included.
Is it hard to start?
Owners report easy starts thanks to the i-30 system. Follow the choke and purge-bulb steps in the manual for reliable cold starts.
