PROBLEM TO BE SOLVED: To provide a liquid chemical spraying vehicle that can secure a spraying accuracy and protect a spraying boom by preventing the liquid chemical spraying under a high speed travelling due to a wrong operation of a worker. ! SOLUTION: A liquid chemical spraying vehicle is structured by including first and second gear shift levers (61, 60) for shifting gears of first and second gear shifting units (22, 23) serially connected to a transmission system, and a work lever (17) for switching on/off of the liquid chemical spraying using the spraying boom (15). The vehicle includes a linkage mechanism (73) for switching an operating range of the first and second gear shift levers (61, 60) in conjunction with a lever position ensuring a speed lower than a predetermined vehicle speed suitable for liquid chemical spraying, when the work lever (17) is in the on-position, and thereby prevents the breakage of the spraying boom (15) caused by the liquid chemical spraying under a high speed travelling d |
