PROBLEM TO BE SOLVED: To provide a crushing arm exclusively used for timber, capable of squashing timber and efficiently cutting timber having a large diameter and which has a function holding a stump and drawing it out. SOLUTION: A base unit is constituted of an arm support body constituted of a circular flange 3c connecting side plates 3a, 3b, a hydraulic cylinder 4, a bracket 5 for working machine, and a link mechanism as a transmission means of drive force. A pair of crushing arms 2A, 2B corresponding to an object are fitted through respective pins 8 so as to pivotally support the intermediate part at the side plates of the arm support body. Claws 9A, 9B facing the inside (pinching pressure side) are welded by welding or the like. Pressing and cutting blades 9a, 9b breadthwise sharpened at the tip respectively are fitted by bolts 9c, 9d, in the claw 9A, 9B.
