Make the first cut until the depth is 0.9 m (3 ft). The depth is less in material that is difficult to load. Keep the outer edge of the cut straight and clean. When an external ramp is used, carry the load low. Also avoid backing out of the excavation whenever it is possible.

When the first cut reaches a depth of 0.9 m (3 ft), start the second cut on the opposite side. Stockpile material at the front corner. Cut out the middle area to the same depth as the end cuts. Repeat the procedure until the desired depth is attained.
