the chipper. Further more if you have a heavy duty resistor laying around the contactor could break the motor by directinginduced armature current through the resistor. (you could also short the armature but I think that would chew up the contactorrather quickly).
Won't work. When you cut and short the armature, you'll also be cutting power to the field. Without field current, the motor is nothing more than a spinning metal thing.
The only reason this works for the mower motors is because their field is constant (ie: magnet motors)
Annoys me to no end with the snowblower. Chris
