    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.

    How can it having "no lift" be of any use...especially if the grass has any moisture on it? Maybe the lift from the top blade when running doubles is enough? Dunno...would have to see this combo in action first.

    I am not sure if it is the same blade or not but Bladerunner has introduced a flat blade to be used with a standard blade. I was told for some of the same reasons that you listed but mainly for no loss or little loss of hp.

    I could see this being of use in a doubles situation...... 2 extra cutting edges with little or no extra blowout????...
    Might be worth a try...

    all 4 sides sharpened? I only see 2 like on a regular blade :confused:

    Also I had a 21" Toro with a perfectly flat blade like that. It cut awful and had zero suction so it never pulled the grass up and left a bad cut. Also have a 32" single blade deck for my old Bush Hog garden tractor with a perfectly flat blade. It cut OK but same problems as the little Toro but it was made better by the fact that it was a big deck that was deeper so the grass had more room to stand up. I could see it being helpful in a double situation as mentioned..

    Its the same Idea as the double blades on my Honda-They dont make a "X" pattern, they lay flat over each other-see pic below...
    The bottom blade gives lift, while the top one acts as a "mulch only" blade. Being on top of the high lift gives it better opportunity to recut grass being pshed up into the top of the deck by the high lift blade-- so yes, flat blades DO have their use.

    BHB looks like the blades are reversible---flip-em over and you've got instantly sharp blades.
