Thoughts on two blades per spindle?

[south jerz]

I recently ordered a TTHP 36" with a mulch kit. I'm picking it up Friday. I called my dealer and asked if he could put on two blades per spindle in a +(plus sign) configuration. He said he couldn't do it because of safety regulations, and he said it's bad for the bearings. I realize that an Exmark dealer probably can't endorse this method because of warranty issues, etc. But is this method OK to use on these mowers? Will it reduce the life of the mower/engine significantly? Thanks

i did it on my TT 60" and the center blades pop off during operation. Had the bolts real tight and everything, and it still came off.

NO NO people do this but not for me.

I think you would have to be nuts! I would overstess the spindles, engine, etc... They are designed to only run one blade, by adding another one it throws the balance and everything off which will cause problems! Not to mention if the dealer ever found out the warranty would be gone
