Abstract: A bucket claw system and method of use wherein the bucket claw system comprises a bucket, either wedge shaped or flat bottomed, that is attached to a piece of heavy equipment such as a loader or skid-steer, wherein the bucket further comprises a plurality of teeth on the outside of the bucket, on the back portion of the bucket, in the area of the transition from the bottom portion of the bucket and the back portion. The bucket claw system can be used by rotating the front edge of the bucket up, exposing the plurality of teeth to the ground, and then moving the plurality of teeth along the ground in order to clear an area of scrap limbs, brush, vines, grass, roots, and undergrowth.

Abstract: A blade assembly for removing a membrane from a bridge deck during a road resurfacing project includes a plurality of independently mounted blades that are able to conform to the contours of a bridge deck, separate the membrane from the bridge deck, and form the separated portions of the membrane into narrow strips or rolls.

Abstract: A pavement cutter is provided for attachment to the boom assembly of a conventional backhoe or excavator including an elongated cutting blade having a scoring edge disposed in substantially parallel relation to the surface of the pavement and a cutting edge disposed substantially perpendicular to the scoring edge and wherein a pair of outwardly extending pressure flanges are attached to the blade one on each thereof at a point above the scoring and cutting edges of the blade. The pavement is first scored along a straight line using the scoring edge and then cut along the scored line using the cutting edge of the blade. The pressure flanges on each side of the cutting blade slide along the top surface of the pavement applying a vertical or downward force which prevents the asphalt from lifting and breaking up during the cutting operation.

Abstract: An apparatus (20) for attachment to earth working equipment (10). The apparatus (20) is illustrated with a cutting wheel (21) rotatably supported about a horizontally extending axle (22). The apparatus (20) has a support structure (33) with a pair of parallel plates (33) which are generally G-shaped defining a slot (34) with a pair of bucket engaging edges (36) for engagement with a cutting edge (42) of a backhoe bucket (13) or like equipment. The support structure (23) is attached to the backhoe bucket (13) by the clamping action of a pair of counter-threaded screws (24) retained in a pivotable plate (27) and aligned above a pair of arcuate pivot blocks (25).

Abstract: A portable pavement cutting device removably attachable to a blade of an earth moving machine includes a cutting disc having a plurality of sawtooth-like cutting teeth disposed around the entire periphery of the cutting disc for cutting into asphalt pavement. The edges of the cutting teeth adjoin to form a continuous cutting edge around the entire periphery of the cutting disc. The cutting disc is freely rotatably supported between a pair of bifurcated fork arms extending downward from a common base. A V-shaped attachment bracket is attached to the base for receiving the cutting edge of the earth mover blade. Clamping bolts are utilized to clamp the attachment bracket element to the cutting edge of the earth mover blade. A "jack-hammer" mechanism is attached to and supported by the base. A high pressure air source activates the jack-hammer mechanism, which causes the cutting teeth to dig into the asphalt pavement, cutting it as the earth moving machine slowly rolls along the asphalt pavement.

Abstract: A pavement cutting wheel assembly is arranged to be secured to the earth engaging tool of a motorized earth moving vehicle by a clamping device, and an element of the clamping device is arranged to use the force on the cutting wheel during its cutting operation to increase the clamping effort of the clamping device.
