PROBLEM TO BE SOLVED: To solve problems that, in a conventional example of structure, rainwater gathers on a step floor in operating in the rain, where an operator moves on the step floor in supplying seedlings, and the step floor tends to be slippery and dangerous, by draining water and preventing gathering of the rainwater, and to facilitate viewing of the position of front wheels.SOLUTION: The riding type seedling transplanter having a seedling transplanting part installed as vertically movably on a rear part of the traveling body, and a plurality of see through-holes (40f) capable of seeing through the position of the front wheels (2) installed on the step floor (34) of the traveling body, wherein the plurality of see through-holes (40f) are constituted as longer in width direction at a front side matching to the inside steering angle of the front wheel (2), and the front end of the front wheel (2) protrudes to outside from the step floor (34) in steering the front wheels (2) to outside.COPYRIGHT: (C)2011,JPO&INPIT【課題】 本発明の課題は、雨水が溜らないように水抜きすることによって上記問題点を解消せんとするものである。また、前輪の位置が見易くなるようにするものである。【解決手段】 走行車体の後部に昇降可能な苗植付部を設けてある乗用型の苗移植機において、走行車体のステップフロア(34)には、前輪(2)の位置を透視できる複数の透視孔(40f)を設け、複数の透視孔(40f)は、前輪(2)が内側に切れる角度に合わせて前側ほど横幅方向内側に長く構成され、前輪(2)を外側に切ったときは該前輪(2)の前端がステップフロア(34)から外側に突出する構成とした。【選択図】 図5
