Then they showed a lawn mower with a switch for the blades, enabling the
user to stop the blades when the thing runs over a sidewalk. Not a bad
safety feature... but when I cut my lawn years ago, I'd simply tilt the
thing back so the blade lifted away from the concrete.

An idiot make up that commercial. I have a Honda lawn mower that I bought
in 1987 and it still runs like new. My 18 year old Honda mower has that
same feature. The blade brake feature is intended for you to be able to
walk away from the mower with out having to restart the motor when you
return. The side walk thing left me puzzled. Using the blade brake to stop
the blade every time you cross a side walk will wear out the blade brake
clutch in very short order.
