| 摘要 | PURPOSE: To eliminate danger to damage a connecting rod or a driving member by providing a support body structure, which is extended orthogonally to working direction, and providing a safety system which can rotate a working tool behind an obstacle. CONSTITUTION: A mower is linked through a 1st chassis 4 to a connector 2 of a tractor 3, and joint relays 9, 11, 12 and 13 are arranged so as to form a deformable parallelogram. A 2nd chassis 14 and its working instrument 15 can be matched well with ruggedness on the surface of the ground. A safety system 43 prevents support body structure 17 from being rotated backward to a support body structure 18 around a relay 21 composed of a shaft 20 and a U link 31 and rotates the support body structure 17 and the working instrument 15 backward to the support body structure 18 because of obstacle and a limiting member 57 limits its rotating angle.
