had a trimmer that advanced the line right.(clip) ANy advice?
Those trimmer heads that advance the line by bumping the ground have never
worked well for me either. When the string breaks off short, you have to
take the whole thing apart to rethread it, which is a big time consuming
pain. So, I solved the problem by buying an aftermarket trimmer head which
does not use an internal spool. When the string gets short or breaks off,
just insert new lengths from a spool you have lying nearby. Also, this type
of cutter head will accept very heavy line, which works better, does not
wear as fast or break as easily.
I think that is why the professionals seem to prefer this type.
