Head of a Stihl string trimmer stops moving and makes a bad noise. What could be the problem?

Answer

It could be a couple of things. Possibly the clutch is worn or the clutch springs have broken. The clutch is located up near the engine. Also, the drive shaft may have broken or the section where the shaft joins with the head could be damaged.
