Claims

[Claims for Utility Model Registration] A work implement R is detachably connected to the tractor 1 via a three-point linkage mechanism 9 consisting of a central top link 10 and a pair of left and right lower links 11, and both lower links 11 can be raised and lowered by a lifting device 3, and the PTO shaft 8 of the tractor 1 and the input shaft 2 of the working machine R
9 are releasably connected, the work machine side ends of the top link 10 and both lower links 11 are connected by a connecting body 14, and when the connecting body 14 is raised, the working machine R is connected to the center in the left and right direction. The upper part and the left and right sides of the connecting body 14 have engaging parts 88 and 89 that are removably engaged with each other, and the engaging part 88 of the connecting body 14
, 89, and a clutch device 28, the clutch device 28 is disposed on the connecting body 14 approximately in the front-rear direction and is movable in the axial direction. A movable tube 32,
An operating device 33 that moves the movable cylinder 32 in the axial direction and can freely change and hold the position between a tractor-side holding position and a working machine-side holding position, and an operating device 33 that is supported within the movable cylinder 32 and is interlocked with and connected to the PTO shaft 8. The connecting body 14 has a connecting shaft 49 having a portion 53, and the connecting body 14 has an engaging portion 88, 8.
9, the operating device 33 causes the movable cylinder 32 to change its position from the tractor-side holding position to the work machine-side holding position.
The connecting portion 53 is releasably connected to the connecting portion 52 of the input shaft 29, and between the operating device 33 and the connecting shaft 49,
When changing the position of the movable cylinder 32, the connecting shaft 49 is rotated about the axis together with the movable cylinder 32, and the connecting part 5
Rotating mechanism 7 that makes 2 and 53 correspond in the circumferential direction
5. A coupling device for a tractor and a working machine, characterized in that it is provided with:
