Head fell off STIHL grass trimmer FS 38 is it worth fixing?

Whether it's worth fixing your STIHL FS 38 grass trimmer depends on the extent of the damage and the cost of repairs. If the trimmer is otherwise in good condition and the cost of replacing the head is reasonable compared to the price of a new unit, it may be worth fixing. However, if the repair costs approach or exceed the price of a new trimmer, it might be more economical to invest in a new one. Consider your budget and how often you use the trimmer before making a decision.
