摘要： A waste processing machine for reducing material and having a feed assist system. A cutting assembly on a frame reduces material. A feed system on the frame directs material toward the cutting assembly. A winch assembly includes a line with a line end for securing material, and a driver on the frame to urge the line end toward the driver. A keeper fixed to the frame secures the line end. A sensor detects utilization between: a docked configuration with the line tensioned against between the driver and the keeper; and an undocked configuration with the line loosened. A control unit allows operation of the feed system in the docked configuration, and interrupts the feed system in the undocked configuration. A feed mechanism actuation bypasses the interrupted operation to advance material for a bypass period, and a limit mechanism overrides operation of the feed mechanism for a subsequent limit period.

摘要： A wood chipper includes a frame, an infeed system, a rotatable cutting system, and at least one feed wheel disposed between the infeed system and the cutting system to feed wood material to the cutting system. The wood chipper also includes a winch which includes a winch line having a first end, and a collar disposed adjacent the first end of the winch line. The wood chipper further includes a detector adapted to detect a first and a second position of the winch line, wherein the detector is adapted to allow operation of the at least one feed wheel and prohibit operation of the winch when the first position of the winch line is detected, and to allow operation of the winch and allow operation of the at least one feed wheel in a predefined manner when the second position is detected.

摘要： A stump grinder for a powered cutting wheel attached to a boom is disclosed, wherein the improvement relates to a cutting wheel confinement system which includes a cutting wheel further comprising a coaxially disposed spindle extending from an unsupported side, and a boom which further comprises an opening which is centrally disposed with the spindle and sized so as to allow the spindle to freely rotate therein without contact when the cutting wheel is not rotating, and to allow for a predetermined amount of eccentric motion of the spindle before the spindle makes contact with the first opening, and which prevents more than a predetermined amount of eccentric motion of the spindle by confining the eccentric motion of the spindle via contact with the first opening.

摘要： An apparatus for use with a vehicle to reduce plant material includes a frame having first and second mounting brackets, a boom coupled to the frame and having first and second mounting plates, a drive assembly having a drive shaft, a cutting device rotatable with the drive shaft, a reinforcing member to support the boom, a first bearing assembly sandwiched between the first mounting bracket and the first mounting plate, and a second bearing assembly sandwiched between the second mounting bracket and the second mounting plate. Each bearing assembly has an exterior annular member, an interior annular member, and a rolling element disposed between the interior and exterior members. The rolling element permits movement of the exterior and interior members relative to one another to facilitate rotation of the mounting plate relative the mounting bracket to permit pivotal movement of the boom relative to the frame.

摘要： A waste processing machine for reducing material and having a docking safety system. A cutting assembly on a frame reduces material. A feed system on the frame directs material toward the cutting assembly. A winch assembly includes a line with a line end for securing material, and a driver on the frame to urge the line end toward the driver. A keeper fixed to the frame secures the line end to the frame. A docking subassembly, spaced from the keeper, is movable between: a docked position with the line tensioned against the subassembly between the driver and the line end secured to the keeper; and an undocked position with the line loosened against the subassembly. A control unit allows operation of the feed system when the subassembly is in the docked position, and at least partially limits operation of the feed system when the subassembly is in the undocked position.

摘要： A material reduction system and processing tool for a material processing machine. The material reduction system comprises a tool holder fixedly mounted to a rotary drum. A leading member defines a raker surface oriented away from the operating direction at a first predefined angle. A processing tool is removably coupled to the tool holder. A leading face of the processing tool is oriented toward the operating direction at a second predefined angle. The first and second predefined angles are such that material is directed into contact with the reducing member to limit material contact with the tool body and the tool holder. An upper flange of the processing tool directly abuts the tool holder to direct material away from the tool holder. The upper flange and a lower flange define a tool recess configured to receive a projection from the tool holder to prevent rotation of the processing tool.
