The present invention relates to a fluid spray-type grass cutting apparatus. According to an embodiment of the present invention, the fluid spray-type grass cutting apparatus can cut grass effectively and cleanly even in a work area such as a road or the like where a weeding process is inefficient by using an existing cutter blade-type weeder. Also, the fluid spray-type grass cutting apparatus divides a grass cutting area and allows a grass cutting process to be intensively performed in each grass cutting area, thereby having an effect of remarkably enhancing the efficiency of the grass cutting process and the working speed. The fluid spray-type grass cutting apparatus comprises a nozzle part arranged on a housing and spraying a fluid toward a grass cutting area； a fluid storage part storing the fluid supplied to the nozzle part； an actuator applying hydraulic pressure to the fluid supplied to the nozzle part from the fluid storage part； and a control part for controlling the actuator.본 발명은 유체 분사형 풀깎기장치에 관한 것으로, 본 발명의 실시예에 의하면, 도로변 등 종래 커터날 방식의 제초기로 잡초를 제거하기가 비효율적인 작업영역에서도 풀깎기 작업을 효율적이며 깔끔하게 수행할 수 있고, 풀깎기 영역을 구획하여 각 풀깎기 영역에서 집중적으로 풀깎기 작업을 수행할 수 있게 되어서 풀깎기 작업의 효율성과 작업 속도를 획기적으로 향상시킬 수 있는 효과가 있다.
