<p><P>PROBLEM TO BE SOLVED: To provide a transplanter in which, when a planting clutch is engaged by a transplantation portion-operating means on transplantation work, the travel speed of a travel portion can be controlled to well ensure the accuracy of seedling transplantation. <P>SOLUTION: The transplanter in which seedlings can be transplanted in a field by a transplantation portion equipped with a transplantation speed change means, while travelling a travel portion equipped with a travel speed change means, is characterized by synchronizing the travel speed change means with a speed-increasing or decreasing operation means through a speed change control mechanism, synchronizing a planting clutch disposed in the transplantation speed change means with a transplantation portion operation means, and synchronizing the engaging operation of the planting clutch by the transplantation portion operation means with the control operation of a control means for controlling the speed-increasing operation range of the speed change control mechanism. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
