As shown in FIG. 10, when the work switch (85) is turned on and the constant speed clutch mechanism (59) is turned on, when the flow switch pedal (79) is depressed, the flow switch (80) is turned on. ), The feed chain clutch (58) is first turned on to drive the feed chain (5), and then the cutting switch (80) is turned on in the second stage so that the cutting clutch (71) is turned on. Is turned on and the reaper (8) is driven. When the main shift lever (72) is in any of the slow, neutral and reverse positions, the reaper (8) is first moved at a constant speed by operating the pedal (79). Then, the feed chain (5) is driven with a slight delay, and the culms remaining in the cutting section (8) are smoothly poured into the threshing section (4).
For this reason, for example, even in the edge cutting operation in which the forward and backward movement is repeated, the operation can be favorably performed without the inconvenience that the culm stays or becomes clogged in the vicinity of the handle of the threshing unit (4).
