PROBLEM TO BE SOLVED: To easily grasp how much remaining spraying work can be performed. A spraying support system is capable of spraying a sprayed material based on a remaining amount acquisition unit that acquires the remaining amount of the scattered material from a spraying device connected to a traveling vehicle body and the remaining amount acquired by the remaining amount acquisition unit. A work calculation unit that calculates a possible range and a display device that is provided on the traveling vehicle body and that displays the possible range are provided. The spraying support system includes a travel information acquisition unit that acquires travel information regarding travel of the traveling vehicle body, and the work calculation unit determines one of the sprayable distance and the sprayable time as a possible range based on the travel information and the remaining amount. The calculation is performed, and the display device displays either the sprayable distance or the sprayable time. [Selection diagram] Figure 1【課題】散布作業が残りどれだけ行えるかを簡単に把握することができるようにする。【解決手段】散布支援システムは、走行車体に連結された散布装置から散布物の残量を取得する残量取得部と、残量取得部が取得した残量に基づいて、散布物の散布可能な可能範囲を演算する作業演算部と、走行車体に設けられ且つ可能範囲を表示する表示装置とを備えている。散布支援システムは、走行車体の走行に関する走行情報を取得する走行情報取得部を備え、作業演算部は、走行情報及び残量に基づいて、可能範囲として散布可能距離及び散布可能時間のいずれかを演算し、表示装置は、散布可能距離及び散布可能時間のいずれかを表示する。【選択図】図１
