PROBLEM TO BE SOLVED: To provide a combine harvester that easily checks visually a threshing depth of ear tip by a mark for checking visually a movement direction of threshing depth, easily carries out visual check operation of a threshing depth manual switch by a mark for checking visually an operation direction of threshing depth and appropriately performs threshing depth adjustment by hand. SOLUTION: The combine harvester has a constitution that grain culms reaped by a pretreatment part are adjusted in threshing depth by operating a threshing depth conveying part by operation of a threshing depth manual switch to a shallow threshing side and a deep threshing side, fed and conveyed in proper threshing depth to a threshing inlet 42. The mark 45 for checking visually a movement direction of threshing depth, which checks visually a shallow threshing direction and a deep threshing direction relative to the ear tip position of conveyed grain culms by an operation part 7, is displayed on the threshing inlet 42 and a mark for checking visually an operation direction of threshing depth, which shows a shallow threshing operation state and a deep threshing operation state so as to check visually in the same mode as that of the mark 45 for checking visually a movement direction of threshing depth is displayed on the threshing depth manual switch.
