摘要：
PROBLEM TO BE SOLVED: To provide a transplanting machine that may not take effort in planting alignment even when the planting alignment with existing planting seedlings and ridge sides such as outer circumference planting is performed while reversing, and thereby enables the planting work to be performed smoothly after the reverse travel.SOLUTION: A transplanting machine includes lifting/lowering height sensing means 46 for detecting the lifting/lowering height of a planting work machine 6, reverse switching sensing means 47 for detecting the reverse switching of a traveling machine body 3, and a control unit 50 for controlling the lifting/lowering height of the planting work machine 6 by an actuator 41 based on detection results by the lifting/lowering height sensing means 46. The control unit 50 is configured to be controlled in the reverse lifting/lowering height being a predetermined lifting/lowering height becoming the ungrounded state when detecting the reverse switching of the traveling machine body 3, and is provided with switching means 29 for switching the reverse lifting/lowering height when detecting the reverse switching when detecting the earth ground of the planting work machine 6 between the first lifting/lowering height for the collision avoidance with an obstacle and the second lifting/lowering height being lower than first lifting/lowering height and for use in the position confirmation with a field surface neighborhood part and the planting work machine 6.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2019,JPO&INPIT【課題】本発明は、外周回り植え等の後進しながら既植苗や畦際との植付位置合せを行う場合であっても、植付位置合せに手間がかからず、後進走行後、スムーズに植付作業を実行できる移植機を提供することを課題としている。【解決手段】植付作業機６の昇降高さを検出する昇降高さ検出手段４６と、走行機体３の後進切換を検出する後進切換検出手段４７と、昇降高さ検出手段４６による検出結果に基づいてアクチュエータ４１により植付作業機６の昇降高さを制御する制御部５０とを備え、制御部５０は、走行機体３の後進切換を検出すると、非接地となる予め定めた所定の昇降高さである後進昇降高さに制御するように構成され、植付作業機６の接地を検知している状態で後進切換を検出した際の後進昇降高さを障害物との衝突回避用の第１昇降高さと、第１昇降高さよりも低く圃場面近傍箇所と植付作業機６との位置確認用の第２昇降高さとに切替える切替手段２９を設けた。【選択図】図９
