BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tractor mounted type boom type mowing apparatus having an excellent working efficiency and, more particularly, to a mowing lawn mowing apparatus in which a lawn mower is connected to a tiller by an angle adjusting cylinder at a predetermined inclination angle, It is possible to keep the lawn mower horizontal with the ground, so that the efficiency of lawn mowing operation is excellent, and a plurality of hammer type lawn mowers provided in lawn mowers are arranged in a spiral manner and sequentially act on the ground, The present invention relates to a tractor-mounted boom-type mowing apparatus which is capable of performing a mowing operation even with a relatively small number of hammer-type cutters. A tractor-mounted boom type mowing apparatus having an excellent working efficiency according to the present invention is characterized by comprising a tractor having a power unit therein and capable of traveling on wheels or orbits, and a plurality of tractors, one end of which is pivotally connected to the tractor, A lawn mower connected to the other end of the boom frame and having a cutter for cutting the vegetation on the ground by receiving power from the tractor； And a control panel for controlling the operation of the boom bar and the lawn mover, wherein the lawn mover is connected to the other end of the boom bar at a predetermined inclination angle so that the boom bar can be tilted, And the angle of the inclination angle of the lawn mower It characterized in that the cylinder section further provided.본 발명은 작업효율이 우수한 트랙터 장착형 붐 타입 예초 장치에 관한 것으로, 보다 상세하게는 붐대에 예초기가 각도조절실린더에 의해 일정 경사각으로 틸팅 가능하게 연결되어 하안의 법면 등 비교적 경사가 급한 경사면의 예초 작업시에도 예초기가 지면과 수평을 유지할 수 있어 예초 작업의 효율이 우수하고, 예초기에 구비된 복수개의 해머형 커터가 나선형으로 배열되어 각각 순차적으로 지면에 작용함으로써 힘이 분산됨으로써 예초기의 부하를 줄일 수 있을 뿐만 아니라, 상대적으로 적은 개수의 해머형 커터로도 예초 작업이 가능한 작업효율이 우수한 트랙터 장착형 붐 타입 예초 장치에 관한 것이다.본 발명에 따른 작업효율이 우수한 트랙터 장착형 붐 타입 예초 장치는, 동력장치가 내
