PROBLEM TO BE SOLVED: To save a labor for detaching a linkage mechanism with a lifting operation mechanism for lifting up/down a mower device, and facilitate an attachment work of a rear work device with respect to a machine body rear part.SOLUTION: A sulky work vehicle comprises: a link mechanism 22 capable of suspending and supporting a mower device; a linkage mechanism 4 for causing a link mechanism 22 to link to a lifting operation mechanism; and a work device coupling part 30 to which a rear work device can be attached and from which the same is detached. The linkage mechanism 4 comprises: a first coupling body 41 which can be detachably attached to a rear link 24; a second coupling body 42 coupled to the lifting operation mechanism; and an intermediate coupling body 40 provided at an intermediate position of the first coupling body 41 and the second coupling body 42. The sulky work vehicle has a fixture for coupling and fixing the first coupling body 41 for which coupling with the rear link 24 is released, and the intermediate body 40, in a state of being along the rear link 24.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】モアー装置を昇降作動させるための昇降操作機構との連係機構を取り外す手間を省いて、機体後部に対する後部作業装置の取り付け作業を簡素化する。【解決手段】モアー装置を吊り下げ支持可能なリンク機構22と、昇降操作機構に対してリンク機構22を連係させる連係機構4と、後部作業装置を取り付け及び取り外し可能な作業装置連結部30と、が備えられ、連係機構4に、後リンク24に対して着脱可能な第一連結体41と、昇降操作機構に連結された第二連結体42と、第一連結体41と第二連結体42の中間に位置する中間連結体40と、が備えられ、後リンク24との連結を解除した第一連結体41、及び中間連結体40を、後リンク24に沿わせた状態で連結固定可能な固定具を備えた。【選択図】図6
