A pine nut picking method using an unmanned and non-powered tool having air power and a rope is provided to separate the branches of pine nuts and the pine nuts by hanging plural ropes on a helium instrument and crossing the ropes across each other in a diagonal direction by untying the ropes when the helium instrument goes up. In a pine nut picking method using an unmanned and non-powered tool having air power, ropes, and a fishing line, a person winds ropes while crossing the upper, lower, left, right, front, and rear ropes across each other. Plural ropes are bound in a diagonal direction while crossing each other in all directions. Plural ropes are repeatedly drooped down in a direction of the earth's surface or raised up in a direction of the ground several times. And then, the person pulls or draws the rope in a direction of the ground. |
