I have an Echo SRM2110 that I have been using for about the last ten years-still running strong. The dual line feeder head part that holds the string is stretching out and breaking the last hole. This is only the second one I have gone through in all that time, so they do hold up well. I have gone to 2 Echo dealers for replacement, not minding if I had to buy the whole head. They tell me that the only one now available is the one that takes short sections of line, that you constantly have to reload. :thumbdown: This is a big PITA when I'm trimming along dog kennels as the chain link fence chews up the string in no time. Does anyone know of a source for the old style bumpheads that you can load about 30' on? Thanks in advance for any help.
