PROBLEM TO BE SOLVED: To provide an agricultural implement capable of carrying out ground leveling with expectations by avoiding extreme variation in grounding state of a leveling state of a leveling apparatus 51 even when a traveling machine body is inclined in the longitudinal direction during planting operation in which the leveling apparatus 51 is lowered to operation position.SOLUTION: A leveling apparatus-lifting or lowering cylinder 102 for lifting or lowering the leveling apparatus 51 is installed and a controlling part 100 read the output of a gradient sensor 95 and obtains an angle of obliquity in the longitudinal direction of a vehicle body 15 and the leveling apparatus-lifting or lowering cylinder 102 is operated according to the angle of obliquity. Thereby, height position of a leveling part 52 to a planting apparatus 31 is adjusted by the minute. Then, when the vehicle body 15 is raised to the front, the ground-leveling part 52 is slightly lowered, compared with a case in which the vehicle body 15 is horizontal and when the vehicle body is lowered to the front, the ground-leveling part 52 is slightly raised, compared with a case in which the vehicle body 15 is horizontal.COPYRIGHT: (C)2007,JPO&INPIT【課題】 整地装置51を作業位置に下降させた植付作業中に走行機体が前後方向に傾斜しても、整地装置の接地状態の極端な変動を回避して、期待どおりの整地を行える農用作業機を提供する。【解決手段】 整地装置51を昇降させる整地装置昇降シリンダ102を設け、制御部100は、傾斜センサ95の出力を読み込んで車体15の前後方向の傾斜角を求め、傾斜角に応じて整地装置昇降シリンダ102を作動させることにより、植付装置31に対する整地部52の高さ位置を刻々と調整する。そして、車体15が前上がりの場合には整地部52を水平な場合よりも少し下降させ、車体が前下がりの場合には整地部52を水平な場合よりも少し上昇させる。【選択図】 図3
