。[Claims for Utility Model Registration] 1 Hydraulic cylinder device 10 for tractor body T
A hitch frame F that moves up and down integrally with the three-point linkage mechanism L, which is moved up and down by the three-point link mechanism L, is equipped on the rear end of the three-point linkage mechanism L, and a tilling work machine I is detachably connected to the hitch frame F. , A sensor wire that detects the ground work level of the rotary rear cover 50 of the work machine I and provides feedback to automatically control the control valve of the hydraulic cylinder device 10 is connected between the rear cover 50 and the hydraulic control valve. In a tractor that is linked so that it can freely move forward and backward, the sensor wire is divided into a front and rear pair of a sensor rod 60 that is on the sending side of the detection signal and a sensor wire 29 that is also on the receiving side, and the sensor wire 29 is The rear end of the sensor rod 60 is connected and held to a response lever 30 rotatably supported on the hitch frame F, while the front end of the sensor rod 60 is connected to a sensor lever 58 that is also rotatably supported on the working machine I. When the work equipment I is connected to the hitch frame F by holding it, the sensor wire 29 and the sensor rod 60 are connected.
A working implement coupling device for a tractor, characterized in that a sensor lever 58 and a response lever 30 are detachably engaged with each other so that the levers move back and forth forward and backward in an integrated manner. 2 Attach the reversing roller 32 to either the sensor lever 58 or its response lever 30,
A tractor work implement coupling device according to claim 1, which is characterized in that it is detachably engaged with the other remaining one via the roller 32.
