  • Attachment for clearance of worksites
    Patent number: 9988774
    Abstract: A cutting device adapted to be pulled by a trailer. The cutting device comprises a frame which supports an engine and a cutting drum assembly powered by the engine. The cutting drum assembly comprises a self-aligning mount that allows movement of its drum relative to the frame. The engine is positioned such that its weight is provided to the cutting drum assembly to maintain a consistent depth of the cutting drum. A linear actuator, such as a hydraulic cylinder, allows the frame to pivot internally, so that the cutting drum assembly may be raised and lowered relative to the ground while translating the frame on wheels.
