The differential equation describing deflection, taking into account the initial posture of a wheat stalk, was derived in the previous study. Based on it, the reaction forces and posture of a bunch of wheat stalks were analyzed. First, because deflection characteristics of the wheat stalk undergoing forced displacement depend on its initial posture, the assessment parameter of posture of a bunch of wheat stalks was introduced, and the initial posture was simulated. Further, the reaction forces of a bunch of wheat stalks undergoing forced displacement were analyzed according to their simulated initial posture. The analytical results agreed well with measured values, and it was demonstrated that the reaction forces involving the effects of the initial posture were predicted specifically in the case of a bunch of wheat stalks. In the present paper, the posture of the wheat stalk undergoing forced displacement was also investigated, and the analysis regarding a bunch of wheat stalks was discussed.
