The subject of the present invention is improving maintenance work by placing receiving antenna and location information acquisition part at same location. A chemical spraying work vehicle 1 comprises: a traveling vehicle body 2, a steering handle 8 disposed on the traveling vehicle body, a pest control spraying device 100 that is positioned along left and right sides of the traveling vehicle body when retracted and is extending in left-right direction of the traveling vehicle body when deployed, a reception antenna that receives signals from a artificial satellite, and a position information acquisition part that acquires position information of the traveling vehicle body based on the signal received by the reception antenna. The reception antenna and the position information acquisition part are built in a GPS unit 30 and disposed inside a fuselage below a meter panel 20. The meter panel 20 is made of a material that is permeable to signals from artificial satellite.本新型提供一種藥液播撒作業車，藉由將接收天線和位置資訊取得部配置在相同位置，提升維修保養作業。藥液播撒作業車1係具備：行駛車體2；操縱用柄8，係設置在行駛車體；防治播撒裝置100，在收納時係位於沿著行駛車體的左右兩側的位置，在展開時係向行駛車體的左右方向延伸並將播撒劑向農田播撒；接收天線，係接收來自人造衛星的訊號；以及位置資訊取得部，係基於藉由接收天線所接收的訊號來取得行駛車體的位置資訊；接收天線和位置資訊取得部係內建於GPS單元30，且配置在儀錶板20的下方的機體內部，儀錶板20係由來自人造衛星的訊號能夠穿透的材料構成。
