| A link device for folding a harrow is provided to be applied to all standing angles of a harrow plate and to be operated smoothly because the link device does not come into contact with the other part of the harrow. One end of a link device for folding a harrow is hinge-coupled to the surface of an ascending/descending cylinder, a harrow mounting structure, or a rotavator(B) upper structure, and the other end of the link device for folding a harrow is hinge-coupled to an coupling arm(47) formed at one end of a connection arm(46). The link device(100) includes a first rod, a middle pipe and a second rod. The front end of the first rod is hinge-coupled to one surface of the one surface of an ascending/descending cylinder, a harrow mounting structure, or a rotavator upper structure and the rear part of the first rod is inserted into the middle pipe. The rear end of the middle pipe and the front end of the second rod are hinge-coupled. | ||||||

| A harrow folding link device is provided to be able to make the operation thereof smooth even in a case where a harrow plate is erected on the ground at a more than a predetermined angle. A harrow includes a harrow plate(40), an ascending/descending cylinder(20) and left and right ascending/descending rods(21,22). A harrow folding link device(60) is used to fold the left and right harrow plates(42,43). One end of the left and right ascending/descending rods is hinge-coupled to the left and right of the central harrow plate(41). One end of the link device is coupled to the lower part of the other end of the left and right ascending/descending rods. The other end of the link device is coupled to a connection arm(50). A part of the link device has a structure of being bent. | ||||||
