PROBLEM TO BE SOLVED: To make a work unit having a work attachment fixed to an arm separable from a working vehicle. SOLUTION: The working vehicle includes, in general operation, a holder 2, an arm 11 and a cylinder 3, and oscillates the arm 11 by extending and contracting operation of the cylinder 3. The holder 2 is fixed to a frame of the working vehicle 1 which can travel. A working attachment 12 is attached to one end of the arm 11, and the other end of the arm 11 is rotatably and detachably mounted on the frame of the working vehicle 1. A cylinder case 3a of the cylinder 3 is rotatably pin-connected to the holder 2, and a piston rod 3b is connected to the arm 11. When the arm 11 is separated from the working vehicle 1, the other end of the arm 11 is detached from the working vehicle 1, and the piston rod 3b of the cylinder 3 is removed from the arm 11 and pin-connected to the holder 2.
