The crown wheel & pinion are the most stressed parts of the vehicle the arrangement of these two is known as a hypocycloid. A hydrostatic drive works by either mounting the standard hydraulic system hardware onto a reservoir with an attached hydraulic motor or by bolting a housed hydraulic pump & motor to a mechanical axle.

They are used to maintain forward motion, to maintain this momentum both output drive shaft sides covers are removed & the pinion and crown wheel are swapped completely with the differential.
