Echo trimmer string always running back into head

[7394]

I’m still using the speed head that came with my SRM225. The secret to it’s longevity is not bumping it on concrete or asphalt surfaces. It’s getting close to replacement time.

I'm 10 years on my original speed feed head cap. I just bullet proofed it long ago... Cause I do bump on asphalt & concrete, Can't hurt it, it's bullet proofed. It's not wearing because of this little mod. .
