PROBLEM TO BE SOLVED: To provide a sulky tending machine, when rotationally turning in spraying work, capable of preventing damage of a boom caused by contact with a ridge, and preventing an operators unintended lift of the boom during traveling without spraying.SOLUTION: The sulky tending machine includes: a steering handle operation detection sensor, or a travel wheel steering angle sensor and a control part that, when a vehicle speed sensor detects vehicle speed less than a set value during traveling, with booms 3a and 3b extending in the horizontal direction respectively, if a steering angle of a steering handle is detected to be a set angle or more, or a steering angle of travel wheels is detected to be a set angle or more, controls a turning outer boom 3a to lift by a set angle from a substantially horizontal spray attitude, however, when the vehicle speed sensor detects vehicle speed equal to or more than the set value, if the steering angle of the steering handle is detected to be the set angle or more, or the steering angle of the travel wheels is detected to be the set angle or more, regulates the control of lifting the turning outer boom by the set angle from the horizontally extending attitude.COPYRIGHT: (C)2015,JPO&INPIT【課題】散布作業時の旋回時に、畦畔への接触によるブームの破損を防止でき、非散布時等の走行時におけるオペレータの意図しないブームの上昇を防止できる乗用管理機を提供する。【解決手段】ステアリングハンドル操作検出センサ、又は走行車輪切れ角度センサを設け、ブーム3a、3bを左右方向にそれぞれ延びた姿勢で走行中、車速センサが設定未満の車速を検出時に、設定角度以上のステアリングハンドルの切り角度の検出又は、設定角度以上の走行車輪の切れ角を検出すると、旋回外側のブーム3aを略水平の散布姿勢から設定角度上昇させる制御を行い、車速センサが設定以上の車速を検出時に、設定角度以上のステアリングハンドルの切り角度の検出又は、設定角度以上の走行車輪の切れ角を検出しても、旋回外側のブームを左右方向に延びた姿勢から設定角度上昇させる制御を規制する制御部を備えた。【選択図】図7
