Re: (ET) Motor Swap & kill a watt

"Good idea.  And easy to do.  Even one resistor and switch would give me two speeds.  I noticed that the motor has to run in reverse to drive the thrower the right way.  But I don't think that will be a problem."

         The traction motor is biased to provide more torque in the direction that makes the tractor go forward.The series field is going to cost you some efficiency if you are going to be running it in reverse rotation.Torque will also be reduced.

(power).   It would be nice to have 'variable power' - using toggle
switches instead of a cam - so you could choose how far to throw the
stuff, or use minimum power for light snowfalls higher for heavier ones.

Why not breadboard the thing and temp tie it on the dashboard (good ole
Duct tape) to see what develops.  I have a 20 motor here and if you find
that vari power works dcent and useful, I might consider a motor switch
on my blower just to have the added feature.
