For example, in the combine 1 of the present embodiment, as shown in FIG. 6, four laterally driven drive pulling devices 15 except for the laterally driven drive pulling devices 15 at both left and right ends, and the vertically driven drive pulling at both left and right ends. Two longitudinally driven pulling devices 17 excluding the device 17 are configured to be rotatable upward.

  In the combine 1 according to the embodiment of the present invention, as described above, the plurality of longitudinally driven drive pulling devices 17 are each configured by the single tine chain 16, and the plurality of pulling lateral drive shafts 26 are provided. Since power is directly transmitted from the drive sprocket 50 to each chain 16 with tines, it is possible to realize rotation of the longitudinally driven pulling device 17 with the pulling lateral drive shaft 26 as a fulcrum with a simple configuration.

  When the predetermined laterally driven drive pulling device 15 and the longitudinally driven drive pulling device 17 are configured to be pivotable upward with the pulling horizontal drive shaft 26 as a fulcrum, the lower end portion of the vertically driven drive pulling device 17 is located behind it.
