<p>PROBLEM TO BE SOLVED: To solve a problem that, in a sulky type rice transplanter, it is necessary for an operator to perform a switching operation of the drive of a working device and an ascending/descending operation of the working device in addition to a swirl steering operation of a machine body at a swirl, and cannot be dedicated to a steering operation at the swirl, thus causing a problem in terms of swirl operation performance.SOLUTION: A sulky type seedling transplanter in which a seedling transplanting work device is attached to a traveling vehicle so as to be liftable comprises a control device which outputs a command for lifting the seedling transplanting work device when a steering handle is steered at a prescribed angle or larger, preferentially outputs a command for descending the seedling transplanting work device by controlling it according to a traveling distance after the steering handle is steered at the prescribed angle or larger by traveling distance calculation means, and after that, performs automatic swirl control for descending a drawing marker.</p> |
