Re: What rear endnis this ?
These machines have a "Power divider" and thus what appear to be two diff's and two drive shafts. Those rears are not mechanically coupled. They are each driven by the power divider, and that is what accomplished the turning on these machines.
There is a member here in Colorado who posted up a complete over haul of his power divider in his Track Master a couple of years back.
