Trimmer Head for Echo Models

This replacement trimmer head fits Echo SRM-225, SRM-230 and SRM-2620 straight-shaft trimmers. It mounts with an M10 x 1.25 mm bolt and accepts standard nylon cutting line. The black nylon housing and metal internals are built for residential lawn maintenance and light weed clearing.

Thermals, Noise and Power

The head adds approximately 0.66 lb (300 g) to the trimmer shaft and measures 4.09 by 2.17 inches (10.4 by 5.5 cm). Its smooth outlet design reduces line wear and snagging during operation. No additional power draw or cooling is required beyond the host trimmer's normal output.

Build Integration

Installation is a direct bolt-on using the existing M10 x 1.25 mm threaded shaft. The speed-feed mechanism lets you advance line by pressing a button without disassembly. Large internal line capacity reduces reload frequency. Not suited for brushwood, stone clumps or heavy bush clearing.

Questions about this item

How do I install the M10 x 1.25 mm bolt onto my Echo SRM-225 trimmer shaft?

Thread the head clockwise onto the shaft until the bolt seats firmly; the step many miss is holding the gearbox dust cap still with a wrench so the shaft does not spin while you tighten.

When will I need to replace the nylon cutting line on this 400 model head?

Replace the line whenever it wears down to less than 5 cm or breaks; the large-capacity spool holds enough for several reloads before the spool itself needs changing.

What is the first limit I hit when running the SRM-2620 at full throttle for long periods?

The 300 g nylon housing softens first under sustained heat, causing the line-feed button to stick before the metal bolt or shaft shows any wear.
