PROBLEM TO BE SOLVED: To provide a combined harvester which has a reaping portion for reaping the grain straws of a field and a threshing portion for threshing the grain straws and whose reaping portion is automatically driven on the forward travel of the vehicle body, wherein a hand feed threshing work can be performed on the forward travel. SOLUTION: The combined harvester includes a reaping portion, a threshing portion, a threshing clutch, a reaping clutch, an actuator for intermittently operating the reaping clutch, forward travel detection means for detecting the forward travel of the vehicle body, and a control portion for engaging the reaping clutch with the actuator, when a forward travel is detected with the forward travel detection means on the engagement of the threshing clutch, wherein the control portion is formed so that the engaging operation of the reaping clutch is controlled, even when the threshing clutch is in an engaged state and in a forward travel state in the switch-in state of a disposed hand feed threshing switch.
