PROBLEM TO BE SOLVED: To provide a posture control apparatus with which even if one tiller connected to a vehicle main body is replaced with another tiller, the replaced tiller is excellently controlled in position.SOLUTION: Control conditions of each tiller of different kinds of tillers are memorized in a control means managing a position control, the kind of the tiller is judged based on the closest rotation angle of a tilling rear cover in a state in which the tilling rear cover most approaches the rotation locus of a tilling tine and the position is controlled by using control conditions for the judged tiller among the prememorized control conditions.COPYRIGHT: (C)2007,JPO&INPIT【課題】車輌本体の連結された一の耕耘機を他の耕耘機に取り替えた場合であっても、該他の耕耘機の位置制御を良好に行える姿勢制御装置を提供する。【解決手段】位置制御を司る制御手段に種別の異なる耕耘機毎の制御条件を記憶させておき、耕耘リヤカバーが耕耘爪の回動軌跡に最も近づいた状態での該耕耘リヤカバーの最閉回動角度に基づいて当該耕耘機の種別を判別し、予め記憶されている前記制御条件のうち判別された当該耕耘機用の制御条件を用いて位置制御を行う。【選択図】図11
