Well really it is just an attachment I made for the split boom I already had. It is a Echo SRM2400SB. I only had a hedge trimmer attachment for it. I will probably get an edger for it but I thought hey I have these old junk trimmers layin around so I dug up a Homelite curved shaft and cut off the end of it and used it's cable to run it. Easy as pie. Now I have a backup trimmer if needed, or if I just feel like a curved shaft. I love the straight shaft but for postage stamp lawns where everything is close together, a curved shaft might be easier, it seems lightweight. But I hate the Homelite head on it it was always jamming in it's previous life. Well it will work for me and was free. Can ya complain? didn't think so. Only took 15 minutes or so to make. If anyone has a old Homelite trimmer laying around it is real easy. Email me so I can tell you a thing or two to think about before you go cuttin so hastily!
