I have a Stihl 130 I was sure how much i would have use the Articulation Hedge Trimmer Attachment so i went with the cheap brand from lowes. I took the quick change shaft off which leaves it just as the original one from stihl. It goes on the same but for some reason it seems to be pulling hard when you first gas it up. Not sure how the Stihls version works but does this seem right....Seems very heavy too. But 120 dollars less. Is the one from stihl worth the extra 120 if not used alot?
