ABSTRACT:
Method and apparatus for forming spot mounds used in assisting the germination and growth of tree seedlings in reforestation. A crawler moves forwardly while a digging blade connected to a frame is lowered into the soil in order to overturn the soil and form a mound. After the digging blade is lowered into the ground, the digging blade rotates so as to better form and thereafter pass the formed mound without interference.
