<p><P>PROBLEM TO BE SOLVED: To solve the problems of field adaptability of a conventional seedling transplanter equipped with a land-leveling rotor for leveling a field surface just before the transplanting of a seedling by a seedling-transplanting device of the seedling transplanter because the rotor part of the land-leveling rotor is integrally constituted and a technological idea of changing the right and left length of the land-leveling rotor according to the condition of the field is lacked although the seedling transplanter can level the field by leveling the field surface damaged by wheels when turning the machine body, with the land-leveling rotor to improve the operation efficiency. <P>SOLUTION: The seedling transplanter equipped with the seedling-transplanting part 4 through a lifting and lowering link device 3 at the rear side of a traveling car body 2 equipped with the right and left wheels 11 is constituted as follows. The land-leveling working device 27a is installed in a front part position of the seedling-transplanting part 4 at the rear part of the right and left wheels 11 in the side view. The land-leveling working device 27a is constituted by arranging a plurality of rotor members 27c in a driving shaft 70a, and the rotor members 27c at the outside parts are detachably attached to the driving shaft 70a. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
