You might want to consider filling the center diff with something like 500,000+ weight oil, otherwise you might not have any tread left on the front tires after just one run! A Neu 21 series would be huge! When you think of it as the Neu 15 series being the size of the Lehner 19 series, the Neu 21 motors must be bigger than the Lehner 22 motors.
