Summary:PURPOSE:To enable the easy manual control of vertical transplanting motion of a seedling transplanting apparatus and a precise position adjustment to an appropriate working height of a working apparatus through an operating lever by structuring a controlling device in such a manner that the working range of a linking mechanism is controlled by switching the operating position of an operating lever. CONSTITUTION:A rice transplanter is provided with a controlling device 21 for controlling the vertical motion and the transplanting motion of a seedling transplanting apparatus by the operation of an operating lever 23. In this rice transplanter, the vertical motion controlling device is provided with the first sensor S1 for detecting the operating position of the operating lever 23, the second sensor S2 for detecting a swinging angle of the vertical motion of a linking mechanism and a sensor float SF for detecting the vertical swinging displacement of a float 11. The operating range of the operating lever 23 is divided into an automatic controlling range and a position controlling range. When the operating position of the operating lever 23 is in the automatic controlling range, the controlling device 21 engages the transplanting clutch 25 and controls the vertical motion of transplanting. On the other hand, when the operating position of the operating lever 23 is in the position controlling range, the controlling device 21 disengages the transplanting clutch 25 and performs a position control.
