I just bought an older 36" Lesco WB. I can't figure out how to get the blades off of it. I did a ton of searches and found that scag w/b's have a similar set up. The lesco has what I believe is a bolt upside down holding the blade on that runs through the spindle to a giant 1 15/16" nut to the pulley to a standard 15/16" nut. Do I have to take the entire assembly apart to get the blade off? Any help would be great!
