the weed wacker in the photo has a plastic head that holds line. I bought a whole spool of it but must cut each piece and thread it by hand. It is rugged stuff at .105". The head also has bolts that will take plastic flail knives, they really cut well I just haven't put any new ones on in awhile. But if I need to do some serious cutting I replace the head with a saw blade I have that will cut three inch trees. The blade can be sharpened with a chainsaw file. I don't use the blade much since I got a 6 foot brush hog for the tractor, now that baby will hack down some serious timber.
I wish I was on vacation I have been real busy with work thats all..Plus I have been spending alot of my nights with my woman...other than that just busy workin thats all..How about yourself staying busy??
