Re: (ET) Alltrax Controllers and speeds

["Bob Murcek" <rmurcek geisinger edu>]

I ended up making a 7-step thing like Chris suggested for a 4QD
controller because I wanted to preserve the throttle lever and was too
lazy to try to link a pot to it mechanically.  It seems OK, but I don't
ask much of this particular tractor.

What a step back that would be.... Have had my alltrax for better part
of 
the summer and I love it.  It now works like anything else with a
throttle, 
more is faster...without steps! And I get instant direction changes
without 
having to even lift off the throttle. And thus far..no maintenance. I
can't 
wait till pushing snow. In cold weather I used have to wait between
forward 
and reverse..some relay somewhere didn't like the cold.
