Note: Our planetary gearbox, wheel drive gearbox, winch drive gearbox, and track drive unit, are exactly the same with Reggiana Riduttori in installation dimensions, and almost the same with Reggiana Riduttoriin performance parameters. So our planetary gear set and Reggiana Riduttori's can be used interchangeably.
