PROBLEM TO BE SOLVED: To settle the problems because, in a sulky type seedling transplanter freely liftably set with a seedling transplanting operation device on a running vehicle having right and left front wheels and right and left rear wheels for steering and equipped with right and left line drawing markers and a marker operation switching device stopping the movement of the right and left line drawing marker movements, there are yet remaining problems on the view point of turning operability, that, when turning, the operator must do on/off operation of driving of the operation device and up/down operation of the operation device other than the turn steering operation of the machine body, and cannot concentrate on steering operation in turning. SOLUTION: A sulky type seedling transplanter includes a controlling device performing automatic turning control by calculating with a running distance calculating means the running distance since the output of the command of lifting the seedling transplanting operation device to output the command of descending the seedling planting operation device corresponding to the running distance, and, further, comparing rotation number of the right and left rear wheels in turning and switching a line drawing marker of right or left one side and large in the rotation number to be line drawing action state after turning.
