PURPOSE: The sprayer runs back and forth on a narrow way between furrows to spray chemicals with the center of gravity underneath to prevent the tumbling of the machine. CONSTITUTION: An engine is provided to activate movement of the machine with the drive force delivered through a transmission and works a pump for an agricultural chemical tank and sprays chemicals over the farm. A frame(10) of thick steel material is designed to provide a center of gravity of the machine downward and has a pair of wheels(14) rotatable on the back downside. An engine(20) is mounted on the frame to output a driving force. An agricultural chemical tank(30) detachably mounts to store a diluted chemical in water. The frame rear part has a pair of wheels(12) and handle bars. A pump(70) operates through a transmission and a shaft(60) on the frame(10) to distribute the chemical in the tank(30) to a distribution tank through a pump-in port(72) and a hose(76).
