SOLUTION to both the mulching and highlift problem...

I'm trying to do the finite element analysis on whether two or three blades would be better.  Oh and by the way... Don't try this at home kids...!  But I seem to recall someone might have tried the two blade scenario already?

That's brilliantly crazy. Might be a little heavy in the blade weight dept for the current motor size, but has potential. BTW...I think the original 20" mower mulches beautifully.

Add a few more blades and maybe you can remove the wheels as in the Flymo hover mower:

I mowed with a double blade with my 20". Louder and overloaded often. It did have a lot more updraft, but fidnt mulch well at all.

Funny that you also tried it. I never tried the tripple stack lol.

I remember you trying this a long time ago.  I also tried it but it wasn't a smart move.  I think it actually made lift worse as it removes air to work with from the original blade.  You can only chop up air which exists.  What this did for me was dirty up the air.

The only thing that would help is to increase the fin angle on the original blade, and I am ill-equiped to do this without unbalancing the blade.

Perhaps attaching the ego blower to the ego mower to create a vacuum to stand up the grass.  Think of it a a lawn flowbee (if anyone remembers that crazy product)

the Flow-Be seems to be the design seed for the Flymo... just saying.

It has been tried with varying success, but I don't believe anyone stuck with it as it didn't really do much. I would bet that, as far as lift goes, the best bet might be just to stick with the HL blade on its own. Won't help with mulching though.
