しかしながら、特許文献１及び２に記載される茎葉処理機には、処理した茎葉を搬送装置に掻き込む掻き込み手段を有さないため、処理した茎葉の量が多いと、搬送装置に茎葉が上手く入り込まず、茎葉が圃場に落下してしまい、作業者が手作業で拾い集めねばならず、作業者に余分な負担がかかる、という問題がある。 However, since the foliage processing machines described in Patent Documents 1 and 2 do not have a scraping means for scraping the processed foliage into the transport apparatus, if the amount of processed foliage is large, the foliage works well on the transport apparatus. There is a problem that the foliage falls into the field without entering, and the operator has to pick it up manually, which places an extra burden on the operator.

そして、特許文献１に記載される茎葉処理機は、引起こし装置の作業位置を機械的に上下動させる手段が設けられていないため、引起こし装置の作業位置を変更するときは機体の走行を停止させ、作業者が手作業で引起こし装置の作業位置を変更しなければならず、作業能率を低下させると共に作業者の労力を増加させてしまうという問題がある。 And since the foliage processing machine described in patent document 1 is not provided with the means to move up and down the working position of the raising device mechanically, when changing the working position of the raising device, the machine body travels. There is a problem that the operator must manually stop and raise the work position of the apparatus to reduce the work efficiency and increase the labor of the worker.

また、接地部材を圃場に接地させているだけであるため、小さな起伏に対しては反応しないことがあり、的確な作業位置調節がなされないという問題がある。
さらに、特許文献２に記載される茎葉処理機は、引起こし装置を茎葉の搬送装置の前部に備えているため、機体の走行等から生じる振動によって引起こし装置の作業位置が定まらないことがあり、適正な茎葉の引起こし作業に支障をきたすという問題がある。 In addition, since only the grounding member is grounded to the field, there is a problem that it may not respond to small undulations, and accurate work position adjustment is not performed.
Furthermore, since the foliage processing machine described in Patent Document 2 includes the raising device at the front part of the foliage conveying device, the working position of the raising device may not be determined by vibrations caused by the running of the machine. There is a problem in that it causes trouble in raising the appropriate foliage.
