there is no need to go to zero before switching. The Allrax handles a reverse switch very well as it decelerates and accelerates in reverse. I have used a momentary contact on both conversions I have done. A lot of time I don't even lift from the throttle, just hit reverse and go.

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.
