PROBLEM TO BE SOLVED: To dissolve a problem in which, at the beginning of reaping, the advance direction of a machine body is corrected against the will of an operator even if the operator works the machine body at a position separated slightly in the horizontal direction from grain culms in a field and a desired harvesting operation is not carried out. SOLUTION: A reaping part 5 having plural separating bodies 3 and forming grain culm routes 4 between the adjoining separating bodies is liftably installed at the front of an undercarriage 2 equipped with a traveling apparatus 1. The reaping part 5 is equipped with a horizontally reaping sensor 6 which has a detecting part 6a positioned on a drain culm route 4 placed at the side end and outputs correction information on the advance direction of the machine body to right or left side. Characteristically, after the horizontally reaping sensor 6 is advanced to an unreaped culm 7, correction for the advance direction of the machine body is not outputted until the horizontally reaping sensor 6 starts detection after the input of direction operation by an operator even in the case of the position of the reaping part 5 being approached to one side in the horizontal direction.
