I am looking at buying an stick edger. Right now I have 2 dedicated trimmers a shindaiwa t270 and redmax 3000. I also have a stihl fs85 trimmer with the extended reach hedge trimmer attachment. I was trying to decide if I wanted to buy just an attachment for the stihl or buy a separate edger. My question is this... does the edger for the fc75 fit a fs85. Here is the picture of the Item i am talking about. Its off an fc75.
