String Trimmers

I have three weedeaters and only one will even run anymore. Very disappointed. I also own your 54 inch zero turn. I am a huge fan of Husquavarna but am beginning to change my mind. Two of the weedeaters have been in repair shop multiple times and they told me to replace them. They are only a couple years old and only used for an hour or less weekly during summer. They will not crank at all.
