PROBLEM TO BE SOLVED: To provide a combine harvester which can ensure the sufficient cooling of a hydraulic oil without requiring a special cooling means. SOLUTION: In the combine harvester, a reaping suspension base 12 liftably supporting a reaping portion 1 and formed is disposed in a forward and upward inclined posture on the front left side of a machine frame 11 on which a hydraulically driving type continuously variable transmission 13 is loaded; an engine 7 having a cooling fan 7b is disposed on the front right side of the machine frame 11 in parallel to the reaping suspension base 12; an oil tank 14 for storing a hydraulic oil for hydraulically actuated devices including the hydraulically driving type continuously variable transmission 13 is attached along the rear portion of the reaping suspension base 12 in a forward and upward inclined posture; and a bulb block 15 formed by integrally uniting the control valves of the hydraulically actuated devices is attached on the upper side of the oil tank 14 via a space A through which cooling air from the cooling fan 7b can pass.
