Just received a new 2003 Rotary catalog with a blade order I placed. Kinda reminds me of looking through the Sears Toy Catalog at Christmas time when I was a kid. Anyway, one of the "new" items this year is the "GrassHawg" flat blade. It's a perfectly flat blade that is sharpened on all 4 sides. No lift whatsoever, less power used to turn it, less noise, etc. I run mulching blades on my Husqvarna ZTR but for those of you that run doubles, I would think that this type of blade would be perfect for the bottom blade. Have any of you seen this blade yet or tried it? If it's OK with the moderators I can post a picture from the catalog. Moderator let me know.
