I think that one could modify the standard blade by milling a slot in each
arm and sharpening the second
cutting edge of the slot. Some heat treat and re-bend would be necessary,
and LOTS of testing before
one was sure of safety. Balance may be an issue. Current would be higher,
but again, the larger dia motor
is used with longer blades on the E10M. 3 blades = 44" but 2 blades =36".
It can handle the current, but
ANY mulching (including running backwards) involves re-cutting the grass.
One can also try two blades
(which works) but ups the current. Nothing easy.
