Re: (ET) Alltrax controller question

[David Brandt <ev_dave13 yahoo com>]

Hey, Dave.  I was thinking of doing just that by adding a center-tapped 
10K pot to the factory throttle lever (yes, I found some!), and using the 
factory reverse microswitch.  That way, the reverse option would have a 
built in safety that it could only be engaged by first going to zero 
throttle.  The factory lever has enough drag built in to remain steady, 
and I'm used to a lever throttle on a mower.

For now, I'm using a knob and a separate switch until I get the 
mechanicals ironed out.

Can't tell you how well it works yet, as the restoration is only 50% 
completed, and the garage is too hot to work in for the moment here in 
Savannah.  But hopefully this fall I'll be able to make a first mow and 
put up a restoration album.
