ABSTRACT:
A rotary cutting attachment for removing linoleum, tile, mastic, grout, adhesive and the like from floors. The cutting attachment includes a drive plate, an elastomeric ring, a cutter head, a block plate, six cutter blocks and three cutter inserts per cutter block. The elastomeric ring separates the drive plate from the cutter head and allows the attachment to adjust to the contour of the floor. The drive plate and the cutter head have sets of gears which mesh to transfer rotation of the drive plate to the cutter head. In turn, an offset member of the cutter head mates with an offset bore of the block plate to transfer rotation of the cutter head to the block plate. The six cutter blocks are removably mounted to the block plate and three cutter inserts are removably mounted to each cutter block. Typically, three cutting attachments, each driven by a hydraulic motor, are utilized in concert to remove a floor covering. The three cutting attachments are arranged in a triangle such that the cutting path of one cutting attachment overlaps the cutting paths of the other two cutting attachment.
