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 to freely change and hold the movable cylinder 32 between a tractor side holding position and a working machine side holding position, and a connecting shaft supported within the movable cylinder 32 and interlocked with the PTO shaft 8. 49, and after the connecting body 14 engages with the engaging portions 88 and 89, the operating device 33 changes the position of the movable cylinder 32 from the tractor-side holding position to the work machine-side holding position, whereby the connection is completed. A coupling device for a tractor and a working machine, characterized in that a shaft 49 is releasably coupled to an input shaft 29, and the input shaft 29 is covered by a component of a clutch device 28.
