Re: (ET) Alltrax controller question



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.

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.
