It is brand new so has the original string wound. I have had to take the head off twice to feed the string through the outlet. Not sure if our technique using it. Any advice? I know seveal of you have this tool and are very happy. We bought the little tiller with it and the grass blade attachment. - have not used either of those yet, just trying to get familiar with the weed wacker. May go back for the brush blade to use at the end of our pasture behind the electric fence line where brush is growing close to the fence line. We did have some trouble getting used to the choke. The instructions were written very strangely or it could just be us.
