The present invention relates to a motive power driven grass-pickup type weeding apparatus for automatically weeding and simultaneously storing large amounts of grasses by driving force of a working vehicle, such that additional works are unnecessary. The apparatus includes: a main body part movable, having one side thereof connected to the working vehicle provided with a driving unit to transmit driving force and the other side of the apparatus has a storage space for accumulating cut grasses cut, and connected to an elevating part of the working vehicle so as to be move up and down； a weeding part rotated through the driving force of the driving unit, cutting off and removing the grasses from the ground, and rotated after being coupled to a lower portion of the main body part； a cover part formed on a rear side of the main body part, moved up and down and opening/closing the storage space through an elevating member formed on a side surface of the main body part in a state that an upper side thereof is hinged to the main body part, and formed therein with the storage space for storing the grasses； an inflow part formed inside the main body part, formed therein with an inflow path for allowing the grasses cut and introduced from the weeding part to be introduced to the storage space, and including an upper plate and a lower plate； and a discharge part provided at an upper side of the lower plate of the inflow part and having a lower side hinged to the main body part and an upper side connected to the cover part through a connecting member, and rotated by opening and closing the cover part, so that the grasses in the storage space of the main body part are discharged.본 발명은 작업차량의 구동력을 통해 자동으로 대량의 풀을 제초함과 동시에 저장하여 추가 작업을 하지 않도록 하는 동력 구동형 풀 수거형 제초장치에 관한 것으로서, 이동이 가능하며, 구동력을 전달하도록 구동부가 형성되는 작업차량에 일측이 연결되며, 타측으로 절단된 풀이 적체되는 저장공간이 형성되며, 상기 작업차량의 승강부가 연결되어 승강되는 본체부； 상기 구동부의 구동력을 통해 회전되며, 바닥의 풀을 절단하여 바닥에서 이탈시고, 상기 본체부의 하측에 결합되어 회전되는 제초부； 상기 본체부의 후측에 형성되어 본체부 측면에 형성되는 승강체를 통
