PROBLEM TO BE SOLVED: To reliably connect with a transmission system of a mid-mount type working device by a climbing over and forward movement.SOLUTION: A working device connection structure for a riding type working vehicle comprises an engaging connection mechanism B and a parallel linkage mechanism C. The engaging connection mechanism B is provided so that right and left rear links 24 of a linkage mechanism 22 and right and left auxiliary links 37 adjacent to the linkage mechanism in a back and forth direction are pivotally connected with a car body frame 1, and in accompany with a climbing over and forward movement of right and left front wheels 4 which climb over a mid-mount type working device 21, engaging parts 64 of the respective rear links 24 are guided to engage and connect with parts 45A to be engaged of the working device 21. The parallel linkage mechanism C is provided so that a car body side output shaft 68 engaged with an input shaft 47 of the working device 21 to transmit power or shut off the transmission is rotatably supported by a holder 69, free end parts of the right and left rear links 24 and free end parts of the pair of right and left auxiliary links 37 are connected through the holder 69, and hoisting of the output shaft 68 is allowed while keeping a prescribed fitted attitude of the output shaft 68 with respect to the input shaft 47. |
