PROBLEM TO BE SOLVED: To perform a turn which is appropriate for a sulky tending machine.SOLUTION: A sulky tending machine includes: a steering handle operation detection sensor 41 detecting a turn angle of a steering handle 9 or a travel wheel turning angle sensor 42 detecting a turning angle of a travel wheel 4 a boom 3 which is switched between a chemical dispersion posture in which the boom 3 is extended generally horizontally in right/left directions and a road travel posture in which the boom 3 is stored in a boom receiver 14 in a rearward lifted posture and a control unit 13 controlling such that, during travel in the chemical dispersion posture, a detection of a turning angle of the steering handle 9, equal to or larger than a predetermined value, or a detection of a turning angle of the travel wheel, equal to or larger than a predetermined value, causes the boom on a turn outer side to be switched from the generally horizontal dispersion posture to an outer side lifted inclination posture, by lifting the boom on the turn outer side by a predetermined angle while keeping the boom on a turn inner side in a horizontally extended posture in right/left directions.COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明は、乗用管理機に適した旋回を行うことを課題とする。【解決手段】ステアリングハンドル(9)の切り角度を検出するステアリングハンドル操作検出センサ(41)、又は、走行車輪(4)の切れ角度を検出する走行車輪切れ角度センサ(42)を設け、ブーム(3)は左右方向に略水平状に延びる姿勢の薬液散布姿勢と、後上がり姿勢でブーム受け(14)に収納する路上走行姿勢とに切換え可能に構成し、薬液散布姿勢で走行中、設定角度以上のステアリングハンドル(9)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、旋回内側のブームを左右方向に略水平状に延びた姿勢に保ちながら旋回外側のブームを略水平の散布姿勢から設定角度上昇させて外側上がり傾斜姿勢とする制御を行う制御部(13)を備えた。【選択図】 図7
