"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."
EXCEPT..{And there always is
an EXCEPT, isn't there? }
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.
