PROBLEM TO BE SOLVED: To solve a following problem with respect to steering operationability for turning: at turning operation in a sulky type seedling transplanter, an operator must turn on or off a drive of and move up or down a seedling transplanting work device in addition to performing steering operation for turning a machine body, thus preventing the operator from concentrating on the steering operation for turning the machine body.SOLUTION: A sulky type seedling transplanter is provided with a control device which: causes traveling distance calculation means to calculate the traveling distance after outputting a command for moving up a seedling transplanting work device so that control is exerted in accordance with the calculated traveling distance outputs a command for moving down the seedling transplanting work device provides an automatic turning mode for moving down a line-drawing marker and activates alarm means such as an alarm buzzer and an alarm lamp, etc. during the automatic turning mode extending after outputting the command for moving up the seedling transplanting work device until causing the line-drawing marker to move down, but does not activate the alarm means if the machine body operation is stopping with the alarm means activated.COPYRIGHT: (C)2014,JPO&INPIT【課題】 乗用型苗移植機において、旋回時に、操縦者は機体の旋回操向操作以外に、作業装置の駆動の入り切り操作や作業装置の上昇・下降操作をしなければならず、旋回時の操向操作に専念できず、未だ、旋回操作性の点において課題があった。【解決手段】 乗用型苗移植機において、走行距離算出手段にて苗移植作業装置を上昇させる指令を出力してからの走行距離を算出して、該走行距離に応じて制御することにより、先ず苗移植作業装置が下降する指令を出力し、その後に線引きマーカを下降させる自動旋回モードを設け、苗移植作業装置を上昇させる指令を出力してから線引きマーカを下降させるまでの間の自動旋回モード中に、報知ブザーや報知灯などの報知手段を作動させるが、該報知手段を作動させた状態で機体の走行が停止しているときは前記報知手段を作動させない制御装置を設けた。【選択図】 図8
