Abstract

PURPOSE:To prevent a machine body from greatly deviating from the set height from mud surface, by providing a controlling means for keeping the machine body at the set height from the paddy surface on the basis of sensing by a surface sensor only a period of the set interval without sensing by the mud surface sensor. CONSTITUTION:A surface sensor 9 for sensing the height from the surface (S) of paddy field is provided at a shorter sensing interval than the set interval of a muddy surface sensor 7 and the second elevation controlling means for operating the machine body on the basis of sensing by the surface sensor 9 is provided. During a period when sensing of the mud surface is not carried out by the mud surface sensor, the machine body is kept at the set height from the surface of the paddy field by the surface sensor and second elevation controlling means.
