PROBLEM TO BE SOLVED: To provide a combine harvester enabling grounding reaping operation while avoiding a reaping part's going into the ground and high-level reaping. SOLUTION: The combine harvester is such that the reaping part 10 is joined swingably and liftably to the front of the self-traveling machine body. Besides, this combine harvester is equipped with a grounding part 18 provided on the reaping part 10 and a balance-supporting mechanism 21 functioning to support the reaping part 10 so as to reduce the grounding pressure of the reaping part 10, and in addition, a stopper mechanism 51 for variably setting the descending limit of the reaping part 10, a grounding detective mechanism 72 for detecting that the grounding part 18 is in contact with the ground, and a control mechanism 70. The control mechanism 70 operates the stopper mechanism 51 as follows: When the stopper mechanism 51 is under active mode, the stopper mechanism 51 functions to set the descending limit of the reaping part 10 at a higher level, while when the stopper mechanism 51 is switched to inactive mode, the stopper mechanism 51 functions to set the descending limit of the reaping part 10 at a lower level.
