Abstract: A system and method for automated bending of wood strips. The system includes an preprogrammed automated robot arm that is fitted with a gripper for grasping and manipulating the wood board around a hot mandrel in order to bend the wood into intricate bent shapes. The wood strips are first soaked in water so that they pliable to bend around the mandrel. The heated mandrel plasticizes the lignin to allow the fibers to reorient in the wet wood strips thus fixing or locking the wood in the bent shape. The grippers are preferably pneumatic grippers formed from two plates that move towards each other to grasp or clamp onto the wood strip. A friction plate urges the wood strips against the heated mandrel to provide consistent and constant contact between the wood strip and the surface of the hated mandrel.

Abstract: A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.
Abstract: Embodiments provide a log splitter with an extendable, or otherwise movable, work zone to increase the accessibility of the work zone for a user and improve movability of the log splitter. The log splitter may be configurable to be in an extended position, a compact position, a vertical position, or a moving position. In the extended position, the log splitter may split logs in a horizontal direction, and in the vertical position the log splitter may split logs in a vertical direction. When the log splitter is in the moving position and/or the compact position an operator of the log splitter may manually move the log splitter to a new position and/or location, or tow the log splitter with a vehicle.

Abstract: An apparatus and methods for limiting the return stroke and modifying the extension stroke of a log splitter. A control rod is translated in the direction of the return stroke of the log splitter. An effort end of a trip arm coupled to the control rod is moved in the direction of the translation and a load end of the trip arm is moved in the opposite direction. The rotation of the load end causes a control lever of the log splitter to move from its rearward position to an intermediate position thereby stopping the return stroke.
