It is aimed to provide a work attachment capable of being stably supported in a folded state and preventing breakage of a working device cylinder and a link mechanism, and a operating machine provided with this. A working device cylinder 32 and a link mechanism 33 are provided at an upper surface side of an arm 27 in a folded state so as to be located between a leading end part of the arm 27 and a boom 25 in the folded state, an inter-boom cylinder 30 and arm cylinders 31 are located above a base end part of the arm 27 in the folded state, and a grounding part 27a groundable over a length range sufficient to support an entire work attachment 24 is formed on at least a part of the lower surface of the arm 27 in the folded state.
