PROBLEM TO BE SOLVED: To facilitate the turning operation of a walking transplanter adopting a crawler type traveling device at a traveling part.SOLUTION: The transplanter is constituted as follows. A traveling machine body 9 includes transmission cases 19 having one end sides supported by the traveling machine body 9 and the other end sides equipped with the crawler traveling devices 18, and front wheels 14 positioned in front of the crawler traveling devices 18, in the right and left both sides of the traveling machine body 9. The power from an engine 11 is transmitted to input shafts 83 provided on one end sides of the right and left transmission cases 19, and transmitted from the input shafts 83 to driving shafts 87 provided on the other end sides of the transmission cases 19. Each of the right and left crawler traveling devices 18 is equipped with a driven wheel 99 integrally rotating with the driven shaft 87, idlers 100 and 101 positioned below and in front and back of the driven wheel 99, and a crawler belt 15 wound on the driven wheel 99 and the front and rear idlers 100 and 101. The power is transmitted from the engine 11 through a steering clutch 52 to each of the right and left input shafts 83, and a steering brake 91 for braking the input shaft 83 is provided in one end side of each of the right and left transmission cases 19.COPYRIGHT: (C)2010,JPO&INPIT【課題】 走行部にクローラ式走行装置を採用した歩行型の移植機の旋回操作が容易に行えるよう工夫する。【解決手段】 走行機体9の左右両側に、一端側を走行機体9に支持し他端側にクローラ式走行装置18を設けた伝動ケース19と、クローラ式走行装置18の前方に位置する前輪14とを備え、エンジン11からの動力は左右の伝動ケース19の一端側に設けた入力軸83に伝達されると共に入力軸83から伝動ケース19の他端側に設けた駆動軸87に伝達され、左右各クローラ式走行装置18は、駆動軸87と一体回転する駆動輪99と、駆動輪99の下方且つ前後に位置するアイドラ100,101と、駆動輪99,前後アイドラ100,101に巻き掛けたクローラベルト15とを備え、左右の各入力軸83には操向クラッチ52を介してエンジン11からの動力が伝達されると共に左右各伝動ケース19の一端側に入力軸83を制動する操向ブレーキ91を設ける。【選択図】図17
