造に、次に述べる問題があつた。 The above-mentioned lifting treatment device combs up the stem culms planted in the field in advance with a combing device equipped with claws in a forward-protruding position. The system is designed to be able to effectively pull up stem culms that are in a collapsed state, which is difficult to lock, and moreover, the stem culm combing device is placed at the lateral end position and the lateral intermediate position of the group of lifting devices. By making it replaceable, a state is achieved in which an effect is exerted to separate the entanglement between the group of stem culms to be reaped located at a position corresponding to the front of the machine body and the group of stem culms that are not cut, located at the side part of the machine body. , it is possible to perform even better lifting processing by making it possible to use the system properly depending on the working conditions, such as a state in which the group of stems to be harvested can be properly pulled up in a desired posture and delivered to the device. In addition, when the claws of the stem culm combing device are rotated up and down, both sides of the forward movement path of the claws are covered with a cover to expose this part. inconvenience caused by
In other words, in order to avoid inconveniences such as the stem culm entering this part in a horizontal direction and causing stem culm clogging, the lower end of the stem culm combing device is placed at a different position. The following problems arose with the structure that supported the device in a replaceable manner.
