RE: (ET) Using Alltrax in E20

["john briese" <goodguyforsure hotmail com>]

I have the Alltrax in an I-5 which is mostly the same as an E20.  The 
alltrax works great, at 90 degrees mowing lawns and -10 pushing snow.  It 
reverses direction without regard to throttle. it simply ramps down and then 
back up in the other direction.
I don't know how or why it works, but it does. and i  like it
