I stopped by my local stihl dealer to pick up my string trimmer and blower for my new km130, i was talking to him about the bed redifiner, he said he has had 2 different lawn companys buy the blade for the redifiner to use on there edger. I saw a post on here where a guy used an edger blade on his redifiner but has anyone tried this? I was going to buy the redifiner but after he said that it got me thinking, why wouldn't that work. He said he hadnt heard from either guy that bought them as to wheather they worked or not. I would have just bought the blade but they didn't have one in stock.. Do any of you guy's know if this will work?
