Does anybody know what part # their factory blades are? Just bought a new set from my dealer and I think I ruined one already. I don't know what size hole the blades have in them. My air comp. went to hell on me so I havn't been able to take one off. I am definately considering buying aftermarket online. Does anybody use aftermarket Hi lift blades. Don't think I am interested in Gators. All help will be apprieciated.
