PROBLEM TO BE SOLVED: To solve the problems wherein the possibility of disordering the conveying posture of grain culms by the contact of the root sides of the grain culms conveyed by a threshing-depth conveying part with a grass-dividing rod is present because the height of the grass-dividing rod in the storing posture based on the ground becomes equal to or higher than that in a grass-dividing operation posture. SOLUTION: The combine harvester equipped with the grass-dividing rod (51) capable of changing the posture between the grass-dividing operation posture (51b) for dividing the unreaped grain culms by being extended from the side part of a pretreatment part (5) to the unreaped ground side of the pretreatment part (5) connected to the front part of a machine body (3), and the stored posture (51a) following the side part of the pretreatment part by a posture-changing means (50) is obtained by constituting the posture-changing means (50) so that the height of the grass-dividing rod (51) based on the ground in the stored posture (51a) may be lower than that in the grass-dividing operation posture (51b).
