*insert Tim Allen grunt*
"URRRGH?"

That *entirely* depends on the speed in which the shaft of the engine
rotates. Plus, an electric motor will struggle *much* more with taller
grass that a gas-powered engine will. This will slow the electric motor
down, thereby decreasing the blade speed.

No? =)

Not ever having an electric mower, your comment raised a question.
Electric edgers often use a dc motor, which maintains mostly constant
speed with varying loads. It seems this would also work with electric
mowers, or am I missing something?
