Abstract: Wood splitters configured and sized to be removably attach to an articulating arm on a mobile power machine such as backhoes, tractors, excavators or bulldozers. The articulating arm is attached to a powered wood splitter, which comprises a pusher comprising a wood holder area and an opposed splitter knife attached to the opposed thumb. The power of the mobile power machine is then activated to open the powered wood splitter to either capture/grab a piece of wood or to release it, or to close/squeeze, the pusher and splitter knife together, thereby splitting the wood held between them.

Abstract: An auto-powered mobile machine with controls for a riding operator and a system for carrying and making controllable use of a tool includes a wireless radio communication component that sends signals from controls in the cab to a wireless electronic control component that operates tool actuators. The wireless electronic control component is powered by a hydraulic generator that obtains power from hydraulic lines from a hydraulic pump powered by the machine's engine.

Abstract: A coupling system for coupling a tool to be carried over the earth to a mobile tool carrier. The system includes an attachment base for attaching the coupling system to the mobile tool carrier and a center pivot assembly with a pivot that allows a tool support arm to swing to either side of the tool carrier where it extends to the side to allow the tool to be used to the side while the machine moves forward. The support arm includes a vertical hinge that divides the arm into two parts, allowing the arm to fold so the tool can be either in front of the machine or beside the machine. The tool may be connected to the support arm with a quick-coupler having hooks or with a permanent attachment.

Abstract: An auto-powered mobile machine with controls for a riding operator and a system for carrying and making efficient use of a variety of attachable tools. Wireless radio communication from the controls to a lower tool may allow the swivel to spin any number of times without limitation. Hydraulic tool position controls are wirelessly coupled to a remote sensor that responds to a string datum line, a curb, direction of gravity, or GPS data.

Abstract: An excavator machine with a side mounted silt fence installing tool mounted below the swivel. The excavator has a swiveling and articulating tool and an operator's seat above the swivel. An articulating arm is attached above the swivel so the operator may operate swiveling and articulating tool in a coordinated way with the silt fence installer to accomplish a job more efficiently than it could be accomplished using tools separately mounted one at a time.

Abstract: An auto-powered mobile machine with controls for a riding operator and a system for carrying and making efficient use of a variety of attachable tools. Most of the tools operate in a linear fashion and are most effective when held to one side of the machine with respect to its direction of movement. The machine includes wheels or tracks, a mounting base for attaching a controllable tool and, above the mounting base, a swivel on which sits an operator's seat and controls. An articulating arm is attached above the swivel so the operator may operate in a coordinated way a lower tool which does not swivel and an upper tool which does swivel to accomplish a job more efficiently than it could be accomplished using tools separately mounted one at a time. Wireless radio communication from the controls to the lower tool may allow the swivel to spin any number of times without limitation.

Abstract: A sidewalk grader provided for grading a sidewalk base disposed along a curb of an existing road structure. The sidewalk grader comprises a tracking assembly fixable to a vertically adjustable backfill blade of a compact excavator positioned to move forward over an existing road structure to advance the sidewalk grader. The tracking assembly comprises a vertically adjustable tracking means disposed for engagement with the top surface of the curb, to provide a reference point. A grading assembly is mounted to the tracking assembly. The grading assembly comprises a frame, and a grading blade rotatingly mounted to the frame to permit adjustment of slope of the blade. An adjustable link connects the grading blade to the frame to adjustable fix their relative position.
