A spice harvester is a large, heavy, mobile factory designed to harvest the Spice Melange. It is dropped by carrier ships (known as Carryalls) onto spice fields. These machines would then harvest and process the spice off the top of the desert floor. This immense farming mechanism is used solely on Arrakis, as it was the only known source of spice before the Tleilaxu developed a substitute.
