It did very good work edging too, I just struggled with the factory (dealer ?) installed line on the trimmer, it is probably just too old and dry, kept breaking on me, or getting stuck in the head, forcing me to turn the engine off and rewind it several times.
Believe it or not, but if you give the cutting line for around 24hours in a bucket with water it will be much more flexible, soft and doesn`t break so easily. I didn`t believe it by myself until I`ve tried it and I can say it really works for me. I really need less line for the same work now and it doesn`t get stuck so much in the head.
