PROBLEM TO BE SOLVED: To provide a work vehicle in which a work device can be attached and detached easily.SOLUTION: A seedling transplanter 1 as a work vehicle comprises lifting link mechanisms 32 provided in a vehicle body 2 and attachment/detachment mechanisms 6 provided in the lifting link mechanisms 32 for attaching and detaching a seedling planting apparatus 3. The attachment/detachment mechanism 6 comprises: a receiving hitch 61 to which the seedling planting apparatus 3 is mounted a mounting hitch 62 provided in the seedling planting apparatus 3 and connected to the receiving hitch 61 a rolling shaft 63 attached to the mounting hitch 62 for rotating the seedling planting apparatus 3 laterally a rolling rock member 64 which is provided in the mounting hitch 62 and capable of restricting the lateral rotation of the seedling planting apparatus 3 and a mounting lock member 65 provided in the receiving hitch 61 for locking the mounting hitch 62. The rolling lock member 64 restricts the lateral rotation of the seedling planting apparatus 3 before connection. The mounting lock member 65 allows the rolling lock member 64 to rotate the seedling planting apparatus 3 laterally when the mounting hitch 62 is locked.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】作業装置の着脱作業を容易に行うことができる作業車両を提供する。【解決手段】作業車両としての苗移植機1は、走行車体2に設けられた昇降リンク機構32と昇降リンク機構32に設けられ且つ苗植付装置3を着脱する着脱機構6を備える。着脱機構6は、苗植付装置3を装着する受けヒッチ61と、苗植付装置3に設けられ且つ受けヒッチ61に接続する装着ヒッチ62と、装着ヒッチ62に取り付けられ且つ苗植付装置3を左右回動させるローリング軸63と、装着ヒッチ62に設けられ且つ苗植付装置3の左右回動を規制可能なローリングロック部材64と、受けヒッチ61に設けられ且つ装着ヒッチ62をロックする装着ロック部材65とを備える。ローリングロック部材64は、接続前では苗植付装置3の左右回動を規制する。装着ロック部材65は、装着ヒッチ62をロックすると、ローリングロック部材64に苗植付装置3の左右回動を許容させる。【選択図】図4
