An automated rotation change system employed in a traditional rice husking machine including a feed hopper, that receives rice grains, connected to a feed header set and a vibrating chute system, a vertical chute, and a husking chamber set, that includes rubber rollers. The rotation change system includes a motor connected to a first pulley that activates, by a belt, a second pulley of a first shaft. The first shaft is connected to a fourth pulley, which activates a fifth pulley of a second shaft together with tightening pulleys on a third and fourth shaft. The fifth pulley transmits rotation to rubber roller of a mobile hub. The third pulley activates the sixth pulley. The seventh pulley is connected to and activates an eight pulley on the fourth shaft, thus making a rubber roller of a fixed hub rotate faster than the roller of the mobile hub.
