摘要： 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.

摘要： 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.

摘要： Device for cutting and/or splitting wood is disclosed. The device comprises a stationary blade co-operating with a reciprocating blade disposed at a front end of a frame, a rear blade having a splitting edge disposed at a rear end of the frame, a movable unit coupled to the reciprocating blade is configured to move along a linear path disposed on the frame. A drive means coupled to the movable unit moves the movable unit forward for moving the reciprocating blade so that a wood received into an aperture of the blade is cut when the reciprocating blade moves pasts the stationary blade. The drive means moves the movable unit rearward for pushing the wood there along the path towards the rear blade for splitting of wood by splitting edge.

摘要： 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.

摘要： A log splitting apparatus having stripper plates for stripping logs from a blade member as a piston is retracted into a cylinder. In one arrangement, the stripper plates are removably securable to opposing sides of a log splitter frame of the apparatus to allow for replacement of the stripper plates with other stripper plates or other components (e.g., stroke reducing devices), use of multi-way (e.g., 4-way) wedge systems, and/or the like.

摘要： A log splitter apparatus and method for splitting logs includes an upward facing wedge and a shroud secured to the upward facing wedge. The shroud can have a positioning aperture defined therein that is positioned over the upward facing wedge to position an associated log on the upward facing wedge for splitting of the associated log by the upward facing wedge when a downward force is applied to the associated log at an upper end of the associated log that is opposite a downward end positioned at or adjacent the upward facing wedge.

摘要： Utilities (e.g., apparatuses, systems, methods, etc.) for use in loading power equipment such as log splitting apparatuses onto cargo trailers or the like in manners that increase the number of assembled log splitting apparatuses that can be loaded onto the cargo trailers (or otherwise result in more efficient loading of assembled log splitting apparatuses onto the cargo trailers) while facilitating assembled presentation of the log splitting apparatuses after unloading from the cargo trailer.

摘要： A feed sensor detects location of a wood log to be moved with a feed mechanism in relation to a predetermined point in a device. A control circuit controls a feed mechanism to feed the log for a preset length on the basis of the location of the log detected by the feed sensor. The control circuit controls the cutting mechanism to cut a wood block from a log longer than the predetermined length when the feed mechanism has fed the log for the preset length and a splitting mechanism to split the wood block cut from the log.
