Craftsman Hassle Free III Trimmer Line —
Ive one of the first 4cycle trimmers that Sears offered, its a heavy 34cc bear, It came with this type of line. I tear up weeds that have turned into brush with these lines.. With normal trimming I can get quite a few cuts before having to replace the line. (Ive had the trimmer for about 4 or 5 years now, and I just used up the last one out of the 20 (10 red 10 black) pack I bought at the same time) Very easy to change, MUCH MUCH better than one ones you have to smack off the ground.
Great Design!!!!!
