After reading the posts below regarding the benis of using 2 blades. I was wondering if anyone has done this with a Toro Pro-line. The blade spindle bolt area has kind of a bracket attached and you can not put 2 blades together. I was thinking of putting some washers in first to bring the blade level with the bracket so I could put on the 2 blades. Has anyone tried this? I am open to any suggestions or what has worked for you. Thanks all!
