PROBLEM TO BE SOLVED: To perform favorable harvesting work by properly pulling up a foliage of a crop by using a pull-up device.SOLUTION: A crop harvester comprises left and right traveling devices (84L, 84R), a pull-up device (64) which pulls up a foliage, and a drawing transportation device (19) which grips the foliage pulled up by the pull-up device (64), and draws out the foliage from a field. Left and right centers of the pull-up device (64) are displaced to left and right one-end sides with respect to left and right centers between the left and right traveling devices (84L, 84R). The pull-up device (64) comprises a circulation mechanism of pull-up lugs (63a) which are arranged in left and right directions in a plurality of rows, the pull-up lugs (63a) pull up the foliages while circulating in each row, the pull-up lugs (63a) at left and right one-end sides out of the pull-up lugs (63a) in a plurality of the rows are formed of soft materials, and the pull-up lugs (63a) in the rows at left and right other-end sides are formed of hard materials which are harder than those of the pull-up lugs (63a) in the rows at the left and right one-end sides.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】 本発明は、引起し装置により農作物の茎葉部を的確に引き起こして、良好な収穫作業を行うことを課題とする。【解決手段】 左右の走行装置(84L,84R)と、茎葉部を引き起こす引起し装置(64)と、該引起し装置(64)で引き起こされた茎葉部を挟持して圃場から作物を引き抜く引抜搬送装置(19)とを備え、左右の走行装置(84L,84R)間の左右中央に対して引起し装置(64)の左右中央を左右一側に偏位させた農作物収穫機において、引起し装置(64)は、左右に複数列に配置された引起しラグ(63a)の周回機構を備え、引起しラグ(63a)が各列ごとに周回して茎葉部を引き起こす構成とすると共に、複数列の引起しラグ(63a)のうち、前記左右一側の列の引起しラグ(63a)を軟質材で構成し、左右他側の列の引起しラグ(63a)を前記左右一側の列の引起しラグ(63a)よりも硬質の素材で構成した。【選択図】図2
