When harvesting the culm with the combine 1 and harvesting, when reaping the grain culm of the furrow, the culm is directed to the harvester 3 of the combine 1 at a substantially right angle state, and when reaping is performed, In order to prevent each plant 5 and the like of the reaper 3 from contacting the ridges, the raising and lowering switch 25a provided on the operating device 25 is turned on, and the narrow guide 4 at the front of the reaper 3 The weeding body 5 and the respective raising devices 6 and the like are simultaneously raised and rotated together as one unit. The CPU 26a of the control device 26 provided in the operating device 25 controls the extension operation of the raising cylinder 21 so that these narrow guides 4 The respective weeds 5 and the respective raising devices 6 and the like are simultaneously and integrally moved to a predetermined height position by using the raising and rotating frame 17 at the upper end of the raising support frame 16 as a rotation center (b) and controlling the rotational movement. It is a configuration that is performed. When the raising control is performed to a predetermined height position, the raising cylinder 21 is automatically stopped by the CPU 26a, and the raising control is stopped. Further, when the raising / lowering switch 25a is switched ON, the raising cylinder 21 is contracted and controlled by the CPU 26a, and the narrow guide 4, each weeding body 5, each raising device 6 and the like are simultaneously and integrally returned to the original lowering position. This is a configuration in which dynamic movement control is performed.
[0022]
The expansion and contraction operation and the stop of the raising cylinder 21 are performed by a switching operation of an ON / OFF switch type raising and lowering switch 25 a provided in the operation device 25.
