The present invention relates to a trimmer for an excavator provided with a rotating device. According to the present invention, the trimmer is connected to the excavator arm performing a swing movement through a link connection and converts a rotational force of a hydraulic motor of a blade operating device, which rotates by a hydraulic pressure of an excavator hydraulic device, into eccentric motion using an operating link member, and moves an operating blade of a tree cutting device in a straight reciprocating motion to cut an object to be cut. In addition, a hydraulic motor of a hydraulic rotation device is rotated by the hydraulic pressure of the excavator hydraulic device, thereby simultaneously rotating the blade operating device, the tree cutting device, and a blade guide device. Accordingly, the efficiency is improved as cutting work can be performed on a wide range of objects to be cut (cutting tree branches and pruning fences) and at various angles. 본 발명은 회전장치가 구비된 굴삭기용 트리머에 관한 것이다. 본 발명에 따르면 스윙 운동을 하는 굴삭기암에 링크연결부로서 연결되고, 굴삭기유압장치의 유압으로서 회전하는 칼날작동장치의 유압모터 회전력을 작동링크부재로서 편심운동으로 전환하여 수목절단장치의 작동칼날을 직선 왕복운동시켜 절단대상물을 절단하도록 구성하고, 굴삭기유압장치의 유압으로서 유압회전장치의 유압모터를 회전시켜 칼날작동장치, 수목절단장치 및 칼날가이드장치를 동시에 회전시킴으로서 넓은 범위의 절단대상물의 절단작업(나무가지 절단 및 울타리 전지)과 다양한 각도로 절단 작업이 가능하여 능률이 향상되는 효과가 제공된다.
