I purchased an ECHO Speed Feed trimmer head for my Stihl FS-250R. It arrived today just a little while ago. Brand-new and ECHO OEM.
Installation was simple and straight-froward. I had to install a different threaded bushing in the ECHO head. It came with a total of four different sized / threaded bushings. Stihl requires the green one.
It's always seems to be a bit of a mystery when it comes to disassembling trimmer heads. Instructions were a bit vague. Anyways, I got the head apart and installed the correct sized bushing. Once you do it, you get a feel for future dis-assemblies.
I purchased the ECHO Speed Feed on E-Bay. It was $29.98 shipped. It arrived within three days of ordering. It's going to be so much easier to re-load line when it's time. No need to remove the head and pull it apart to get to the line spool. You can re-load on the spot if you wish. And, it's made in
USA.
