PROBLEM TO BE SOLVED: To prevent performing of a material supply work in a state in which a material has run out.SOLUTION: A work vehicle comprises: a material supply device coupled to a rear part of a travel vehicle body； a first sensor 61 for detecting a residual quantity of the material on the material supply device； a second sensor 62 for detecting presence of the material on the material supply device； and a notification control part 12A for performing material run-out notification processing when a fact that a material has run out, is detected based on detection of the first and second sensors 61, 622. The notification control part 12A performs deceleration processing for decelerating vehicle speed to prescribed speed in the material run-out notification processing.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】資材切れ状態で資材供給作業が行われることを防止する。【解決手段】作業車において、走行車体の後部に連結される資材供給装置と、資材供給装置における資材の残量を検出する第１センサ６１と、資材供給装置における資材の有無を検出する第２センサ６２と、第１センサ６１及び第２センサ６２２の検出に基づいて資材切れを検知した場合に資材切れ報知処理を行う報知制御部１２Ａとを備え、報知制御部１２Ａは、資材切れ報知処理において車速を所定速度まで低下させる減速処理を行う。【選択図】図２
