best 21 in. blade????

[gogetter]

I'd like to hear about some 21" blades, specifically mulching blades.

I have a 21" crapsman that I don't use too often, but when I do the cut is terrible. Since it's used so little I can't justify spending alot on a commercial unit.

So, I've been looking at different blades. Was wondering if anyone has had any luck significantly improving the cut by switching to a different blade?

Doesn't snapper make a "ninja" blade that is kinda like a "Y" at each end giving it a doube blade effect? Wonder if it's any good.

Then sears has a few funky looking mulching blades with weird ends on them.

Anyone have any input? Thanks.

go ahead and mount some BALANCED doubles, i've done it and recieved terrific results with them.

Ninja's are the best mulching blades, but can be a bear to sharpen the secondary edges. Doubles on a 21" ? Haven't tried it yet. Do you have to fabricate a special holder to keep the "X" formation?

I have the best results with doubles and side discharge, type of blade doesnt seem to make a lot of difference, except 2 high lift mulch blades together didn't work well .

no brackets are required to mount just tighten like normal
