Sorry Paul, not following you on this, center steer using the standard R36 steering is no problem, my problem is what happens with the 2 gearboxes and are you thinking of using the 2 existing motors to drive each gearbox in its standard form. I think it gets far two complicated, building a wider deck seems a lot easier and when you think about it it only brings the deck out the width of a Victa Toecutter on each side. Might be easier to just mount a Toecutter out on each side laugh
