Claims

[Scope of utility model registration request]

Atsupa link 4 at the rear of the agricultural tractor 1,
A three-point link mechanism 3 formed of a pair of left and right lower links 5, a lift arm 6, etc. is provided, and an engaging body 1 is provided at the rear of the pair of left and right lower links 5, respectively.
7, the left and right engaging bodies 17 are integrally connected by a connecting rod 16 to form a fixture 15, and the engaging body 17 has a shaft that engages with an engaging shaft 14 provided on the agricultural working machine side. The mounting member 15 is attached to the eccentric shaft 1 so that the engagement groove 22 is suspended with respect to the lower link 5 with the engagement groove 22 open to the outside.
9, and the engagement groove 22 is formed so as to rotate vertically when the agricultural tractor 1 is moved backward and the attachment 15 collides with an agricultural working machine.
