The present invention relates to a check chain for agricultural machinery, and more particularly, can be easily separated and coupled to the tractor connecting portion and the body portion, and can prevent the complete separation of the working machine connection when adjusting the length of the work machine connection due to the rotation of the body portion It is about a check chain for agricultural machinery. The present invention is a work machine connecting portion 10 is connected to the work machine, the work machine connecting portion 10 is coupled to one side of the body portion 20, and the tractor connecting portion 30 is pin-coupled to the other side of the body portion 20 In the agricultural machine check chain made, a bolt shaft 22 is formed to protrude outward on one side of the body portion 20, and the screw shaft 22 is screwed to the inside of the work machine connecting portion 10. A nut shaft 12 is formed, and the nut shaft 12 is hung on one end of the nut shaft 12 which is moved without interference in the work machine connecting portion 10 and inserted into the work machine connecting portion 10. A locking pin 23 is provided at the end of the bolt shaft 22 to prevent separation of the work machine connecting portion 10 during rotation, and a fixing hole formed at the other side of the body portion 20 to adjust the length of the check chain. The pin is coupled to the connection hole 32 formed in the 24 and the tractor connecting portion 30 Stop ring for supporting the tractor connecting portion 30 is fixed to the other outer circumferential surface of the body portion 20 by the stop pin 42 so that the separated fixing pin 25 is smoothly recombined when separating the pin 25 ( 40) is provided.본 고안은 농기계용 체크체인에 관한 것으로, 더욱 상세하게는 트랙터연결부와 몸체부를 용이하게 분리결합시킬 수 있고, 몸체부의 회전으로 인한 작업기연결부의 길이를 조절하는 경우 작업기연결부의 완전분리를 방지할 수 있는 농기계용 체크체인에 관한 것이다.본 고안은 작업기에 연결되는 작업기연결부(10)와, 상기 작업기연결부(10)가 일측에 결합되는 몸체부(20)와, 상기 몸체부(20)의 타측에 핀결합되는 트랙터연결부(30)로 이루어진 농기계용 체크체인에 있어서, 상기 몸
