Abstract
PURPOSE:To prevent the unnecessary vertical motion of a combine by limiting the output when the moving speed of the machine is below a prescribed level and to prevent the delay of control by control the output corresponding to the variation width from standard height when the moving speed of the machine is above the prescribed level. CONSTITUTION:A reaping part 5 is vertically shifted by an electronic controlling means utilizing an ultrasonic sensor 12. When the moving speed of the machine body 1 is slower than a prescribed level, the reaping height is controlled by outputting only one signal even a sequence of output signals of same direction are continued over a specific period. The violent motion of the machine body can be avoided by this process. When the machine speed is faster than a prescribed level, the reaping height is controlled by the output signal corresponding to the variation width from the standard height.
