PROBLEM TO BE SOLVED: To provide a transplanting machine in which the turning steering control for assisting the steering operation in the turning by a power steering device can be provided at low cost, in the transplanting machine with a control unit for executing auto planting control of automatically moving a planting machine up and down in the planting work.SOLUTION: A transplanting machine is provided for executing auto planting control to lift a planting machine 6 in a non-working position by steering operation, and then to lower and operate the planting machine 6 in a planting working position on condition of traveling a predetermined distance. In the transplanting machine, a power steering device 32 is controllably provided by a control unit 50. When a steering operating speed of a predetermined value or more is detected by an angular velocity detection sensor 29 for detecting a steering operating speed as the operation detection means, the turning steering control to increase assist force from the power steering device 32 is performed.SELECTED DRAWING: Figure 12 |
