Are these available? Heres the situation. From what i've seen others on this forum do is install Scag(generic)21 inch long, 3in wide .25in thick 5/8 center, flat, notched Hi-lifts on my 04 60" 28efi Super-Z. The chute has been opened up & spacers installed. These Really help give a excellent cut...BUT at the cost of extra drag on my 28efi. Side by-side these scag blades dwarf standard fusions. BUT these blades combined with 10-12in tall thick wet(morning dew)grass/weeds can really put a strain on my hustler. The suction difference vs. standard fusions is amazing(it sounds like a jet engine under the deck). I'm now wondering if a hi-lift fusion could give me the benefits of the 3in notched hi-lifts without bogging me down quite so much.????
