A mollusc farming machine deploys a tillage assembly connected by a support frame to a vehicle platform. The vehicle platform enables the user to mechanically traverse the tillage assembly across an aquaculture harvesting area, digging into the earth of the harvesting area in order to harvest clams and other molluscs. An agitating mechanism causes reciprocal motion of the tillage assembly in order to break up the aquaculture earth as a tilling section of the tillage assembly is displaced at an angle through the earth, forcing the earth and any buried molluscs onto the tillage section. The agitating motion further serves to sift the earth by causing dirt, plant matter and other debris to fall through spaces between a plurality of sifting rods of the tilling section, leaving behind any molluscs previously buried within the earth to be easily collected by workers.
