 - Greetings to Chris, RJ, and all others -

Yes, RJ, I agree fully and thankfully with the dramatic regenerative 
braking
capability.  That function kept me out of trouble when using the E20 to 
move
the O'Day Daysailor around on our side of the hill.

Without knowing the complete state of the tractor controls at the moment 
Chris engaged the motor, my analysis was speculative and best-guess, at 
best.
Thanks for your comments.
