Claims

[Scope of claim for utility model registration] Top link 10 and a pair of left and right lower links 11
The working machine R is removably connected to the tractor 1 via a three-point linkage mechanism 9 consisting of A connecting body 14 is provided that connects the end portions of the working machine side to each other, and the connecting body 14 has an upper engaging portion 22 on the top link 10 side and a lower engaging portion 18 on both lower links 11 sides. The work machine R has a top mast 29 having an upper engagement portion 45 with which the upper engagement portion 22 removably engages when the coupling body 14 is raised, and a lower engagement portion 18 of the coupling body 14 that engages with the top mast 29. The bracket 31 has a lower sheath engaging portion 46 that can be removably engaged, and a pair of left and right support links 39 that connect the top mast 29 and the bracket 31 to each other. , is provided with a blocking mechanism 47 that releasably prevents the lower engaging part 18 from disengaging from the lower engaging part 46, and when the three-point linkage mechanism 9 is disconnected from the work machine R, the upper engaging part 22 and The distance L in the vertical direction from the lower engaging part 18 is determined by the distance L between the upper sheath engaging part 45 and the lower sheath engaging part 4.
Each support link 39 is formed of an elastic material that biases the top link 29 and the upper cover engaging portion 45 downward so as to be larger than or equal to the distance L1 in the vertical direction from the support link 39 to the support link 39. Connection device between tractor and work equipment.
