Description

  The present invention relates to a paddy field machine having a variable seedling bed width.

  In paddy field machines (passenger rice transplanters) that plant multiple seedlings at the same time, if the number of seedlings to be planted at the same time increases, the width of the seedling platform becomes larger than the width of the traveling machine body and jumps to both sides. In addition, the apron part protrudes on both sides. For this reason, it has the structure which can fold the seed stand of a plurality of seedlings at the time of storing of a paddy field machine, or at the time of transportation between a storage place and a field (for example, refer to patent documents 1).

  In this paddy field machine, the seedling platform and the apron unit are integrated, and the apron unit is folded at the same time as the seedling platform is folded.
