PROBLEM TO BE SOLVED: To provide a harvester in which a limit torque of a torque limiter, i.e., a tradeoff balance can flexibly be changed in the field in situ.SOLUTION: A harvester is characterized as follows: a raking auger is laterally bridged in a rotatable manner around a horizontal axis line through a rotating pivot; a sprocket acceptor formed in a shape of a flange is concentrically mounted by protruding in a radial direction of a rotating pivot, and an outer circumference end face of the sprocket acceptor is formed into a concentric circle arc face; a passive sprocket having a fitting hole forming a concentric circle arc face with the outer circumference end face in a central part is outwardly engaged through the fitting hole in the sprocket acceptor; also, a shear pin facing an axis line in the radial direction of the rotating pivot is interposed so as to be straddled between the passive sprocket and the sprocket acceptor; and thereby a shear force in a rotation direction of the passive sprocket is made to act in a middle part of the shear pin.SELECTED DRAWING: Figure 7 |
