PROBLEM TO BE SOLVED: To solve a problem such that by a conventional 6-wheeled constitution, the stable support of a machine body can be obtained, but since in the constitution, the directions of left and right directions of front wheels and rear wheels can not be changed, the steering property of a machine body and the following property to furrows become inferior.SOLUTION: This seedling transplanter is provided by arranging left and right pairs of the front wheels (5), (5), driving wheels (6), (6) and tail wheels (7), (7) one by one from front side to make the 6-wheeled constitution, installing furrow-guiding rollers (16), (16) making a contact with the slope of the furrow, as left and right freely movable, constituting the front wheels (5), (5) as jointly movable as associated with the left and right transfer of the furrow-guiding rollers (16), (16) and constituting the tail wheels (7), (7) as freely steerable.COPYRIGHT: (C)2008,JPO&INPIT【課題】 従来の6輪構成では、機体の安定した支持は得られるが、前輪及び後輪の左右方向の向きが変向できない構成であるため、機体の操向性、畝に対する追従性が悪くなる問題がある。【解決手段】 本発明は、左右一対の前輪(5),(5)、駆動輪(6),(6)、尾輪(7),(7)を前側から順に配備して6輪構成とする。畝の斜面に接触する畝案内ローラ(16),(16)を左右移動自在に設ける。畝案内ローラ(16),(16)の左右移動に関連して前輪(5),(5)を操舵すべく連動構成する。尾輪(7),(7)は操舵自在に構成する。【選択図】 図1
