To improve smoothness of the operation of a floating mechanism.SOLUTION: An implement includes: a machine frame on which a tillage part for tilling a field is supported; a support frame pivoted to the machine frame in a vertically movable manner and supporting a gauge wheel for setting a tillage depth; a bending link pivoted to the support frame; a tillage depth regulation rod having one end side pivoted to the machine frame and the other end side pivoted to the bending link via a pivot; and a floating mechanism for putting the gauge wheel into a floating state by bending the bending link and the tillage depth regulation rod from an extension state. The floating mechanism has a slide surface disposed in the support frame, a step part projecting upward from the slide surface, and an operation member rotatably supported on the bending link around the pivot, and pushes up the pivot by the operation member and bends the bending link and the tillage depth regulation rod by sliding the operation member to the step part while rotating and sliding on the slide surface, and bringing into contact with the step part.SELECTED DRAWING: Figure 7

    【課題】フローティング機構の動作の円滑性の向上を図る。【解決手段】作業機は、圃場を耕耘する耕耘部が支持された機枠と、機枠に上下動可能に枢着され且つ耕耘深さを設定するゲージ輪を支持する支持枠と、支持枠に枢着された屈折リンクと、機枠に一端側が枢着され他端側が枢軸を介して屈折リンクに枢着された耕深調整ロッドと、屈折リンクと耕深調整ロッドとを伸展状態から屈折させることで、ゲージ輪をフローティング状態にするフローティング機構と、を備え、フローティング機構は、支持枠に設けられた摺動面と、摺動面から上方に突出する段部と、屈折リンクに枢軸回りに回動可能に支持された作動部材とを有し、作動部材を回動させて摺動面上を摺動しながら段部に向けて摺動させ且つ該段部に当接させることで、作動部材によって枢軸を押し上げて屈折リンクと耕深調整ロッドとを屈折させる。【選択図】図7
