Threshers are implements employed in crop harvesting. On the lunar surface of Raada, the farming teams' threshers were manually propelled, levitated using repulsors technology, depended on coolant, and operated on fuel. Kaeden Larte's initial encounter with the newly arrived Ashla, who worked as a mechanic, occurred when she sought repairs for her malfunctioning thresher, which had malfunctioned and caused an injury to her leg. This happened on the moon.
