PROBLEM TO BE SOLVED: To provide a combine harvester designed so that threshing depth can manually be adjusted without confirming threshing depth setting switch by visual observation even when the combine harvester is operating and traveling. SOLUTION: The threshing depth setting switch is arranged so as to coincide with the direction corresponding to each threshing depth position. For example, a switch 105 for manually setting a (shallow) threshing depth and a switch 106 for manually setting a (deep) threshing depth are parallel arranged at same height in front of an HST lever 103 so that the switch 105 at the position distant from an operator can be pushed when it is desired that planted grain culms are kept at a distance from an operator (when threshing depth becomes shallow) and the switch 106 at the position close from the operator can be pushed when it is desired that the planted grain culms are brought to close to the operator (when threshing depth becomes deep). Thus, threshing depth can manually be adjusted even when the combine harvester is operating and traveling.
