Install a Simpler Weed Trimmer Head

Changing weed trimmer line can be a frustrating experience, but there's an easier way. Instead of struggling with big, tangled spools, just lock short lengths into a special replacement head.

Replace the trimmer head

If you've ever struggled to replace or pull out a string trimmer line, you'll love this fix! The frustrating old trimmer head can be replaced with an easy-loading version (adapter required for some models). Echo Inc. (echo-usa.com) produces a universal trimmer head with a string-loading system so simple your kindergartner could figure it out. Short pieces of string line are pushed into the trimmer head, and a locking system catches the line like a fish on a hook. To change the line, simply pull it through the cutter head and push in a new piece.

Remove the old trimmer head as shown in Photo 1. Mounting procedures vary slightly, depending on the brand of trimmer you own, so consult the manual before attaching the new head. Photos 2 and 3 show how to mount the replacement head on machines with threaded shafts. Before mounting the new head, determine which triangular adapter piece and retaining nut fit the threaded shaft.

Several years ago, I remember seeing some sort of retro-fit trimmer head which didn't use actual string, but had a system of more rigid plastic spikes which just looped into the head and were something like a 5 or 6 inch straight piece. I think there were 3 or 4 of these spikes/lines on the head. I have been unable to locate this system anywhere (was I maybe just dreaming this up??). Does anyone know what I'm talking about, and where I might find some info?

I changed the trimmer head on my Echo gas powered trimmer to one of these about ten years ago and have never regretted it. I simply carry a couple of extra pre-cut lengths with me while trimming. I have also switched over to extra heavy string (0.105) I believe. I can almost cut down a fence post (almost) with this setup.
