PROBLEM TO BE SOLVED: To provide a combined harvester and thresher improving controllability and maintainability and enabling driving operation preventing unpleasant feeling and uncomfortable feeling regardless of a target traveling speed.
SOLUTION: An operating amount detection means 25a for detecting the operating amount of a transmission operation tool 25 and a traveling rotational frequency detection means 108 for detecting the traveling rotational frequency of a traveling hydraulic continuously variable transmission 40 are connected to a control means 200. The control means 200 controls the traveling hydraulic continuously variable transmission 40 by a speed command value V calculated by adding a traveling swash plate angle correction value V&thetam calculated from a speed deviation Vs and a traveling control gain G1 to the target traveling speed Vt, to reduce the speed deviation Vs between the target traveling speed Vt calculated from the operating amount of the transmission operation tool 25 and a traveling speed Vr calculated from the traveling rotational frequency of the traveling hydraulic continuously variable transmission 40. The traveling control gain G1 is set to 0 when the target traveling speed Vt is a first set speed V1 or less.
