Doubles on a Toro 21"?

[joed]

Is it possible to put double blades (high lift on the bottom and atomic mulching blade on the top) on a toro 21" proline model?

i've read before on other posts that it doesn't work and that you get a lot of blowout. I would like to find a way for doulbles on Proline 21's too.

Don't laugh, I was sharpening all of my blades a couple of weeks ago and I was trying to decide which ones to put on my little Murray 20". It just came to me to try doubles. I have a lowlift and a mulching blade. Heck, I didn't know what would happen when I cranked it up. I'll tell you it runs great and reduces my clippings by about half. It's a 5.5 Briggs and I haven't had any problems at all. I'm going to do it on my Bob-Cat asap.
