I realize this is an odd time of year for questions on deck blades, but here goes. I have a K46 deck which is left hand discharge. I have seen many references to the left hand discharge blades being much different than right hand discharge blades, but I have not seen an explanation of what the differences are. Could someone explain or show what the differences are? Also, has anyone chucked another brand of mulching blades in a vertical mill and modified them for use with case decks? I have seen many people wish for mulching blades and this doesn't seem to be something that would be terribly difficult, or am I missing something? Thank you in advance for your help.
