PROBLEM TO BE SOLVED: To provide a seeder capable of putting soil in an appropriate amount to a seeding groove regardless of soil quality in a field.SOLUTION: A seeder includes: a seeding device 82 arranged on a travel vehicle body 2 and feeding a seed a hardness/softness detection device 206 detecting hardness/softness in a field a seeding soil covering member 59 embedding a seed fed to a field by the seeding device 82 a soil covering switch member 66 changing soil covering posture of the seeding soil covering member 59 according to detection of the hardness/softness detection member 206 a soil covering adjustment member 208 changing setting of the hardness/softness detection device 206 operating the soil covering switch member 66 and a control device 100 controlling operation of the soil covering switch member 66. When the soil covering adjustment member 208 is operated to a predetermined hardness/softness setting position, the control device 100 changes a soil covering width of the seeding soil covering member 59 and controls a movement range of the seeding soil covering member 59.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 圃場の土質にかかわらず、播種溝に適切な量の土を寄せることが可能な播種機を提供すること。【解決手段】 走行車体2に種子を供給する播種装置82を設け、圃場の硬軟を検知する硬軟検知装置206を設け、播種装置82が圃場に供給した種子を埋没させる播種覆土部材59を設け、硬軟検知部材206の検知により播種覆土部材59の覆土姿勢を変更する覆土切替部材66を設けると共に、覆土切替部材66が作動する硬軟検知装置206の設定を変更する覆土調節部材208を設けると共に、覆土切替部材66の作動を制御する制御装置100を設けた播種機において、制御装置100は、覆土調節部材208が所定の硬軟設定位置に操作されると、播種覆土部材59の覆土幅を変更すると共に、播種覆土部材59の移動範囲を制限する構成である。【選択図】図2
