ok so i have a stihl fs90r trimmer. i called my local dealer and asked if they had a blade attachment for cutting pucker brush and stuff and they said yes the blade a lone is 33 bucks and i have to buy the attachment seperatley. well before i could ask how much the attachment is they hung up on me. does anyone that you know of make a universal type attachment that might be a little cheaper? i only need it for this one job so i dont want to spend a bunch on if right now.
