Ive read about running double blades. My question is do most just stack them staight on top of one another or do you put a washer or two between the blades to create a gap. I was thinking if you put a washer between the blades to create the gap, it will cut the grass into smaller pieces. I have the everride warrior which they do not make a mulch kit. Or how about the gator blades, people seem to like them for leaves, but how do they do for making finer grass clippings?
