The dynamic braking on DC lawnmowers is accomplished by the "shorting"
the motor with a length of wire, believe it or not.
When you turn it off, the power switch on the handle disconnects the
battery from the motor and connects a "resistor" to the motor which is
simply a bundled hank of

Curious.
All corded mowers I assume used AC brushed motors and hence
would work just fine on DC as well. But I assume running such
universal motors on DC is more efficient than running a universal
brushed motor on AC.
So is there an efficiency factor? If the universal AS/DC brushed motor
ran

If memory serves, Lee Hart did something similar with small Gates Cyclon
lead cells many years ago. I hope he'll chime
