PROBLEM TO BE SOLVED: To provide a work vehicle which stops a planting part without impact or vibration exerted thereon, prevents a delay in a lifting/lowering timing of the seedling planting part, and prevents a travel vehicle body from starting traveling backward before a ground contact part separates from a farm field surface even when a backward travel operation is performed.SOLUTION: The work vehicle includes: a lifting/lowering link device arranged in a rear part of a travel vehicle body a lifting/lowering hydraulic cylinder 46 lifting/lowering the lifting/lowering device and a work device 4 on the lifting/lowering device. The work vehicle further includes: a solenoid valve 83 adjusting an oil feed amount to the lifting/lowering hydraulic cylinder 46 a lifting/lowering position detection member 92 detecting a lifting/lowering position of the lifting/lowering link and a control device 100 reducing a lifting speed of the work device 4 by reducing the oil feed amount to the lifting/lowering hydraulic cylinder 46 from the solenoid valve 83 when the lifting/lowering position detection member 92 detects the lifting/lowering link device lifted up to a predetermined position.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】 植付部が停止する際に衝撃や振動が加わらず、苗植付部の昇降タイミングが遅れないと共に、後進操作をしても接地部材が圃場面から離間しない間に走行車体の後進が始まらない作業車両を提供する。【解決手段】 走行車体の後部に昇降リンク装置を設け、昇降リンク装置を昇降させる昇降油圧シリンダ46を設け、昇降リンク装置に作業装置4を設けた作業車両において、昇降油圧シリンダ46への送油量を調整する電磁バルブ83を設け、昇降リンク装置の昇降位置を検知する昇降位置検知部材92を設け、昇降リンク装置が所定位置まで上昇したことを昇降位置検知部材92が検知すると、電磁バルブ83から昇降油圧シリンダ46への送油量を減少させて作業装置4の上昇速度を減速させる制御装置100を設けて構成する。【選択図】 図4
