We saw this motor-driven plough the other day in a rice field.  We think he's ploughing the area before planting rice in it.  It looked like a muddy, yucky job.  We have seen the same thing done with a carabao pulling the plough.  In that case the carabao AND the ploughman get muddy.

This photo shows a field in the distance with young rice plants growing.  Their colour is gorgeous.
