Re: (ET) ET No Go

["RJ Kanary" <rjkanary nauticom net>]

I had limited my choices to tractors similar to the one he has. My daily
driver is an E-20 CA . I prefer the eight speed traction motor control, due
to its providing a smoother take off, and more flexibility in close
maneuvering. My I-5 that committed suicide fifteen years ago will be set up
with that configuration, since I have acquired not one, but two complete
organ donors. The larger jump in armature current on the seven speed models
encourages you to be much more cautious in situations that could involve
inattentive pedestrians, such as I have encountered in some stadium clean 
up
efforts that I have been involved in.
