PROBLEM TO BE SOLVED: To provide a rice transplanter capable of preventing damage to a sensor by contacting a farm field or a headland at a time when a machine body is backed, turned, etc.SOLUTION: A rice transplanter equipped with a float that detects a farm field contact area includes a sensor, provided separately from the float, for detecting a farm field surface. The sensor includes a detection part for tracking the farm field surface and a support part for swingably supporting the detection part, and can be held in a state that the detection part is rocked upward with a swing shaft included in the support part of the sensor being a fulcrum.COPYRIGHT: (C)2016,JPO&INPIT【課題】機体後進時や機体旋回時等に、圃場又は枕地面と接触することによるセンサの破損を防ぐことができる田植機を提供する。【解決手段】圃場接地面を検知するフロートを備える田植機であって、前記フロートとは別に設けられ、圃場表面を検知するセンサを備え、前記センサは、前記圃場表面を追従する検知部と該検知部を揺動自在に支持する支持部を有し、前記センサの支持部に含まれる揺動軸を支点として、前記検知部を上方へ揺動させた状態で保持可能である。【選択図】図5
