Abstract: Provided is a lift table apparatus for log splitting. The lift table apparatus includes a lift frame, a lock pin, a control lever, and a cable. The lift frame is configured to be attached to a beam and a hydraulic cylinder of a log splitter. The lift frame is movable from a vertical position to a horizontal position by the hydraulic cylinder when the hydraulic cylinder is retracted. The lock pin is configured to be attached to the beam and locks the lift frame in the horizontal position. The control lever is configured to be attached to a hydraulic flow control valve of the log splitter. The cable is connected to the lock pin and the control lever. When the control lever is pulled out, the cable pulls the lock pin out to enable the lift frame to be released from the horizontal position and moved to the vertical position.

Abstract: The present invention relates to a Li-Ion battery powered log splitter. The log splitter includes a steel frame having height adjustable legs and wheels for making the device both adjustable vertically and portable. The log splitter also features a hydraulic pump system powered by an integrated direct current (DC) motor. The DC motor receives power from the Li-Ion battery and spins the pump system for activating a steel plate and rod mechanism to section a log of wood placed on a track of the log splitter into at least two pieces. The size and output of the batteries, motor, and pump can be increased or decreased to suit user preference or need, and users can easily operate the log splitter to easily and safely split wood into sections or pieces for campfires, outdoor fire pits, ovens and much more.

Abstract: A pusher assembly for a log splitter can include a frame, an actuator, and a wedge assembly with a first set of cutting blades and a second set of cutting blades configured to split a log into a plurality of pieces. The pusher assembly includes a base configured to be coupled to the actuator, a plurality of push pads, and a plurality of support columns extending between each of the push pads and the base. The plurality of push pads may be spaced apart from the base, and each push pad may include a contact surface that is coplanar with the contact surfaces of the other push pads. The plurality of push pads are configured to receive the first set of cutting blades in gaps positioned between adjacent push pads as the plurality of push pads forces the log through the wedge assembly.

Abstract: A custom bracket hinge which is used a single time during assembly of the log splitter, and a customized shipment stand allow an extremely quick and safe method of swinging two heavy parts of a log splitter trailer together, without lifting either part off of the ground until they are mated and can be swung into position. The first method aspect of the invention consists of the use of the special equipment (double hinge bracket mechanism and stand) to assemble the log splitter in a very small number of steps. The second method aspect of the invention is shipping the log splitter with the equipment, in a much smaller footprint.

Abstract: There is disclosed a system and methods of use for quickly and efficiently excavating, cross-cutting, splitting, and loading or stockpiling tree stumpage and other tree or organic materials, as well as for performing ground cleanup operations. One embodiment provides a stump harvester for attachment to a distal end of an excavator arm. The stump harvester may include front and back jaw assemblies configured to pivot between open and closed positions. The back jaw assembly may include a knife arm having a cutting blade that extends along a majority of a front side of the knife arm. A centerline plane may bisect a cutting edge of the blade. The front jaw assembly may include a planar-aligned dual anvil configured to sheath the cutting edge of the blade when the front and the back jaw assemblies move into the closed position. Other embodiments are disclosed.

Abstract: A tool for log-splitting is provided with a handle structure defining a long axis, and including a first handle and a second handle. The handles extend substantially parallel to the long axis. Coupled to the handles are an axe head including a first wedge and a second wedge with the axe head extending perpendicularly from the long axis of the handle structure to a sharpened edge. The wedges are coupled by a hinged joint providing for the first and second wedges selectively to be aligned together and to be separated. The first wedge includes a notch behind the sharpened edge and the second wedge includes a leading edge that, with the wedges aligned together, is positioned in the notch.

Abstract: A wood splitting turntable assembly includes a base that has an end plate slot therein for positioning around an end plate of a log splitter when the log splitter is positioned in a vertical orientation. The end plate slot has a width of at least 8.0 inches and a depth of at least 9.0 inches. A bearing is coupled to the base and a turntable is coupled to the bearing. A log can be positioned on the turntable when the base is positioned around the base of the log splitter. Moreover, the turntable is rotatable on the base to rotate the log for splitting the log around an entire circumference of the log without requiring a user to lift and reposition the log. An elastomeric band is positionable around the log to inhibit the log from falling apart from the log is split.

Abstract: A firewood processor, comprising a saw, means for feeding wood for the saw, a splitting chute, a splitting wedge arranged to split a log, of which at least part is arranged in the splitting chute, into pieces, a pressure plate arranged to support the log, and means for moving the pressure plate and/or the splitting wedge towards each other in such a way that the log is configured to be split by said movement. In the firewood processor, the splitting wedge is arranged to split the log into an intermediate split log and at least one firewood-ready piece. The firewood processor further comprises a returning element for returning the intermediate split log back to the splitting chute for further splitting and a protector for protecting the user of the firewood processor. The firewood processor is configured to automatically return the intermediate split log, using the returning element, to the splitting chute.

Abstract: A kinetic log splitter having: a frame; a geared rack; a pinion coupled with the geared rack and to cause the geared rack to translate linearly based on rotation of the pinion; an actuation handle that engages the geared rack and the pinion; and a linkage system coupling the actuation handle to the geared rack that allows disengagement of at least a portion of the linkage system in response to a stall condition that occurs due to a stall of the geared rack during the operation of the geared rack of the kinetic log splitter. The kinetic log splitter may be towable and/or include a push plate splinter recovery system.
