All the water from the rice fields has gone now but the ground is still very soft. The rice was harvested using a little combine on caterpillar tracks. It cuts the rice stalks and separates the grain from the straw.
And here it is in action! The rice grains go straight into sacks to be taken away and dried in some kind of drying machine. After that they are polished completely to produce white rice, or partially for brown rice.
Meanwhile Mrs A was cutting the corners of the next field by hand, so that the combine could turn.
