In this state, forming of several m to the corner of the field corner remains, but the hook forming work in the rear working mode up to the subsequent corner is the same as in the first embodiment.

  The present invention can be used when performing a straw forming operation provided around a rectangular field such as a paddy field. In particular, the corners of rectangular fields such as paddy fields can be formed straight to the corners so that there are no unworked parts, and the work can be completed very easily and in a short time, so work efficiency is high and availability is high. .
