By cross-lighting with light from, it is possible to illuminate brighter with appropriate brightness intensively. Thereby, compared with the case where the front of the aircraft is uniformly illuminated, the visibility of the divider 11 at the right end of the aircraft can be improved, and even at night work in a farm field where the planted cereals are severely collapsed, The alignment based on the divider 11 can be performed appropriately and easily.

  As a result, it is possible to suppress a decrease in work efficiency due to overturned culms during night work while improving mobility and workability during night work. Improvement can be effectively achieved. In particular, the alignment of the right-side divider 11 as a reference can be performed appropriately and easily, so that the boarding operation unit 3 is positioned on the already-cut side of the field and the outer-periphery side is planted in the uncut grain culm. It is easy to align the divider 11 at the right end of the aircraft, which is important in performing the harvesting operation for harvesting in order from the cereal, and the planted culm located on the outermost side of the uncut cereal, It is possible to effectively improve the working efficiency in the night mowing work at night.
