Amendment June 29, 1983 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] The tractor 1 is equipped with a three-point link mechanism 9 consisting of a top link 10 in the center and a pair of lower links 11 on the left and right, and the top link 10 and both lower links 11 are connected to the working machine. The side ends are connected by a connecting body 14, and the upper part of the center part in the left and right direction and the lower part of both left and right sides of the connecting body 14 are separably connected to the working machine R, and the PTO shaft 7 of the tractor 1 and the input of the working machine R are connected. In the structure in which the shaft 25 is separably interlocked, the coupling body 14 is provided with a clutch device 24 that separably interlocks the PTO shaft 7 and the input shaft 25 after the coupling body 14 is coupled to the working machine R. , the clutch device 24 has a guide 26 disposed substantially in the front-back direction on the connecting body 14 and an axis in the substantially front-back direction, and is slidable in the axial direction via roller devices 30 and 31 on the guide 26. The equipped equipment tube 27,
It has a connecting shaft 46 that is supported within the equipment cylinder 27 and interlocks with the PTO shaft 7, and an operating device 28 for the equipment cylinder 27, and the roller devices 30 and 31 hold the equipment cylinder 27 movably in the radial direction. The equipment cylinder 27 has elastic members 35 and 38, and by moving in the axial direction, the connecting shaft 46 therein is moved to a connecting position where it is interlockingly connected to the input shaft 25, and the connecting shaft 46 is separated from the input shaft 25. The operating device 28 can be freely changed to the separated position.
A coupling device for a tractor working machine , characterized in that the equipment cylinder 27 can be freely changed and held in a coupled position and a separated position .

Claims (1)

[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 7 of the tractor 1 and the input shaft 2 of the working machine R
