PROBLEM TO BE SOLVED: To provide an implement equipped with a ground-leveling device capable of changing the rotary speed of a rotor so as to be able to perform a field-leveling work efficiently.SOLUTION: This implement installing a working part 4 capable of being lifted up and down to a lowered working state and an elevated non-working state at a traveling machine body 2 and also installing a driving ON- or OFF-operating cable 100 for driving the ON or OFF of gear change of a rotor transmission B to the lower-speed side, which changes the rotary speed of the rotor 27 for leveling the field relative to the traveling speed of the traveling vehicle body 2 to a lower-speed side and higher-speed side jointly with the elevation of a seedling-transplanting part 4, a lifting up and down link arm 108, an upper link 40, a lower link 41, etc., is provided by stopping the rotor 27 on lifting up the seedling-transplanting part 4, and capable of therefore preventing the rotor 27 from incorrectly been operated while it is set at a high-speed or low-speed position.COPYRIGHT: (C)2011,JPO&INPIT【課題】圃場均平化作業を効果的に行えるようにロータの回転速度を変更できる整地装置を備えた作業機を提供すること。【解決手段】走行車体2に下降した作業状態と上昇した非作業状態に昇降可能な作業部4を設け、苗植付部4の上昇に連動して走行車体2の走行速度に対する圃場均平化用ロータ27の回転速度を低速側と高速側に変更するロータ変速装置Bを低速側に変速する駆動入り切りする駆動入切用操作ケーブル100,昇降リンクアーム108、上リンク40,下リンク41などを設けた作業機であり、苗植付部4を上昇させたときには、ロータ27が停止するので、ロータ27が高速又は低速ポジションに設定したままで誤作動されることが防止できる。【選択図】図10
