PROBLEM TO BE SOLVED: To solve the problem in a riding seedling transplanter with a seedling transplantation working implement liftably mounted to a traveling vehicle equipped with steering right and left front wheels and right and left rear wheels, wherein there are still remaining problems in turning operability because an operator has to perform the on-off operation of driving of the working implement and the lifting/lowering operation of the working implement in addition to the turning steering operation of a machine body when turning and therefore cannot concentrate on steering operation when turning.SOLUTION: A travel distance from an operation of steering right and left front wheels to a predetermined angle or more is computed by a travel distance computing means to perform automatic turning control of starting to drive a seedling transplantation working implement after the output of a command of lowering the seedling transplantation working implement according to the travel distance, and a notifying means is provided for notifying that automatic turning control is in progress. The notifying means is configured to notify in such a manner that the lowering timing of the seedling transplantation working implement and the driving start timing of the seedling transplantation working implement is recognized. |
