The combing device 9 has a left and right pulling device 7 in which the uncut stem culm group is located adjacent to each other when the machine body performs a normal circular cutting operation and when performing a middle splitting operation.
a left and right pulling device 7, which is fixed at the front left lateral end position of the machine body 8, and in which the uncut stem culm group is located adjacent to the second pulling device 10 only when the second pulling device 10 performs the work of splitting the machine body in the middle; It is configured to be switchable between the front right lateral end position and the front lateral intermediate position of 8.

Then, the stem culms planted in the field were placed first on the left and right,
It is configured so that the second combing devices 9 and 10 comb it in advance, and then the left and right lifting devices 7 and 8 pull it up into a desired standing position, and it is suitable for work forms such as circular cutting work and middle splitting work. Depending on the second combing device 10
By changing the position to a different position, the second combing device 10 combs up the stem culm to be reaped located at a position corresponding to the front of the machine, and then accurately delivers it to the pulling devices 7 and 8 in that position. A state in which the action is exerted (circular cutting work), and a state in which the action is exerted to separate the entanglement between the group of stem culms to be harvested and the group of uncut stem culms located on the side of the machine body (splitting operation). It is now possible to use it for different purposes.

Next, a structure for supporting the second stem culm combing device 10 so that it can be moved to different positions will be explained based on FIGS. 2 to 4 A and B.
