The one published in Publication No. 132808 is known,
In both of these, the rotary is directly connected to the tractor so that only the rotary can be moved left and right. Therefore, these conventional systems require a special rotary, which is inconvenient and uneconomical because it cannot be applied to existing rotaries and other working machines. Therefore, a technical problem arises that must be solved in order to obtain a left-right movement mechanism that can be applied to existing general rotaries as well as other working machines.

る。 Then, as shown in FIG.
The third mast 28 erected above the gearbox 27 of the moving body 25 is connected to the second mast 20, 2
Connecting portions 31, 3 are connected to the pin holes 20a, 20a of 0 with pins 29, and are fixed to the stay pipes 30 extending left and right from the gear box 27.
1 is formed so that it can be connected to the pin holes 23a of the connecting rods 23, 23 provided on the movable body 25 with pins 32, 32, and the intermediate connecting body 10 is connected to the work equipment connecting device 18.
are attached as described above, the sliding parts 22, 22 of the movable body 25 attached to the tilling device 26 are fitted into the guide part 5 of the intermediate coupling body 10, and the piston 7 is attached to the bracket 24 of the movable body 25. If the piston 7 is connected with the pin 33, the piston 7 can be extended or retracted by, for example, dividing the pressure oil used to operate the lifting mechanism 13 of the mobile agricultural machine 11 and controlling the supply and discharge to the cylinder 6. If it is, the moving object 25
Since the sliding portion 22 of the moving body 25 slides to the left or right along the guide portion 5 of the intermediate connecting body 10,
At the same time, the tilling device 26 is configured to move to the left or right with respect to the mobile agricultural machine 11.

２６の前記左右動を円滑且つ、確実ならしめる。 That is, in the installed state shown in FIG.
5, the tilling device 26 also moves to the left, and if the piston 7 is retracted to the right toward the cylinder 6, the tilling device 26 moves to the left.
It will move to the right. At this time,
Since the cylinder 6 and the piston 7 are interposed between one end of the horizontally long guide section 5 and one of the sliding sections 22,
The expanding and contracting action extends in the extending direction of the guide portion 5, making the horizontal movement of the tilling device 26 smooth and reliable.
従つて、このように耕耘装置２６のみを左方又
は右方へ円滑確実に移動させることができたの
で、例えば畦際にまで移動農機を近づけることが
できない場合であつても、耕耘装置２６を畦際に
移動させることによつて残耕部分の無い能率的な
耕耘作業を効率的に行うことができるのである。 Therefore, since only the tilling device 26 could be moved smoothly and reliably to the left or right in this way, for example, even when it is impossible to bring the mobile agricultural machine close to the edge of a ridge, the tilling device 26 can be moved smoothly and reliably. By moving the plow to the edge of the ridge, efficient tillage work can be carried out without any remaining tillage.
