Claims (1)

[Claims for Utility Model Registration] The tractor 1 is equipped with a three-point link mechanism 9 that is movable up and down, consisting of a central top link 10 and a pair of left and right lower links 11.
The upper and lower ends of the lower links 11 on the work machine side are connected by a connecting body 14, and the connecting body 14 has upper and lower parts that removably engage with the upper part and both left and right sides of the working machine R as the connecting body 14 rises. It has engaging parts 20 and 18, and
A blocking device 92 is provided to releasably prevent disengagement between the lower engaging portions 20, 18 and the work implement R, and the PTO shaft 8 of the tractor 1 and the input shaft 26 of the work implement R are releasably connected. In this case, the coupling body 14 is provided with a clutch device 25, which is disposed on the coupling body 14 in a substantially front-to-back direction and has a pair of left and right guide grooves 32 extending in a substantially front-to-back direction.
a guide 27 having a shaft center, an equipment tube 28 having an axis approximately in the front-rear direction, a pair of left and right mounting mechanisms 29 that provide the equipment tube 28 on the guide 27 so as to be movable in the axial direction, left and right directions, and up and down directions; 28 and interlocks with the PTO shaft 8; and an operating device 30 that moves the equipment tube 28 in the axial direction and can freely change and hold the equipment cylinder 28 between a tractor-side holding position and a working machine-side holding position. Each mounting mechanism 29 has an interlocking shaft 41 that projects outwardly from each of the left and right sides of the equipment tube 28, and a collar 42 that is inserted into the guide groove 32 so as to be movable in the longitudinal direction. , the insertion part 44 of the collar 42 into the guide groove 32 has a pair of upper and lower sliding surfaces 46 that are parallel planes and slide on the upper and lower inner surfaces of the guide groove 32.
A long hole 47 in the vertical direction is formed into which the upper and lower engaging parts 2 are inserted movably in the axial direction and the vertical direction.
After 0 and 18 are engaged with the work implement R, the operating device 3
0, the connection shaft 53 is releasably connected to the input shaft 26 by changing the position of the equipment cylinder 28 from the tractor side holding position to the working machine side holding position. Device.
