The drive system on the steiner is simply an open differential front and rear,in a sunstrand 2500 axle housing,driven by one pump and a pair of hydraulic motors.When going forward the power flows from the pump to the rear motor first,then the front motor then back to the pump in a closed loop.There is no opposite drive I've had them apart,it just feels glued to the ground,I know exactly what your describing,unless you have driven one it's hard to explain how well they transfer power to the ground in all conditions.
