Mowerconsultant : I have done a search on double blades on Hustlers (Super Z) and have read the posts on the subject...but I'm still confused. I want to put doubles on my Super Z 60" in order to mulch up the leaves better. The opinions seem to be different on which blade to use for the top one. Some say standard high lift blades for both lower and uper and some say standard on lower and Gator on top. I don't really care about the spring time and the clumping issue, just fall and the leaves. What do you think?
