PROBLEM TO BE SOLVED: To prevent non-working travel in a high centroid state where a work machine is lifted.SOLUTION: A control section 45 included in a sulky rice transplanter 1 performs warning on a lifting/lowering height of a planting work machine 4 in non-working travel at a time point when the planting work machine 4 reaches or approaches a predetermined lifting/lowering height when a work machine lifting/lowering operation lever 32 is operated, the lifting/lowering operation lever operating the planting work machine 4 to be lifted/lowered, in a travel stop state of a travel machine body 2 and/or a non-working state of the planting work machine 4.SELECTED DRAWING: Figure 7【課題】作業機を上昇させた高重心状態での非作業走行を防止する。【解決手段】乗用型田植機1が備える制御部45は、走行機体2の走行停止状態、及び/又は、植付作業機4の非作業状態において、植付作業機4を昇降操作する作業機昇降操作レバー32が操作されたとき、植付作業機4が所定の昇降高さに到達又は近づいた時点で、非作業走行時における植付作業機4の昇降高さに関する警報を行う。【選択図】図7
