Summary: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 rocking restriction mechanism C. The engaging connection mechanism B is provided so that right and left rear links 24 of a linkage mechanism 22 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 climb over a mid-mount type working device 21, engaging parts 64 of the respective right and left rear links 24 are engaged and connected with parts 45A to be engaged of the working device 21. The rocking restriction mechanism C is provided so that a car body side output shaft 68 consists of a cylinder shaft including a diameter-expansion guidance part 68A which guides an input shaft 47 of the working device 21 to inside thereof, the right and left rear links 24 is arranged to rise forward and rock when disengaged with the input shaft 47, and when moving forward after right and left front wheels 4 climb over the working device 21, the rising forward and rocking of the output shaft 68 is prevented from a prescribed rising-forward attitude to position an engaging start end part of the input shaft 47 in a guidance region of the diameter-expansion guidance part 68A.
