A reversing automatic feed wheel assembly for wood chipper includes an infeed assembly and a rotatable cutting assembly spaced from the infeed assembly. The reversing automatic feed wheel assembly also includes at least one feed wheel disposed between the infeed assembly and the cutting assembly to feed wood material to the cutting assembly. The reversing automatic feed wheel assembly further includes a control system operatively connected to the at least one feed wheel to automatically reverse/stop/restart the infeed of the wood material including a sensor to sense pressure or reduced speed in the wood chipper as a result of an excessive load placed on either one of the cutting assembly and the at least one feed wheel.

A mulcher apparatus includes a tractor and a mulcher unit provided to the tractor. The mulcher unit includes a tooth assembly with a holder and a cutter element with a cooperating notch portion and cross bar arrangement. The notch portion can be retrofit to existing holder arrangements. The cutter element may include various features, to enhance cutting efficiency. For example, the cutter elements may include a double-ended structure, angle tab portions at each corner portion, carbide coatings, a pair of tip portions at each end with a space therebetween, and/or a generally H-shaped configuration.

A side feed wheel assembly for a wood chipper includes at least one side feed wheel adapted to be disposed adjacent at least one primary feed wheel of the wood chipper. The side feed wheel assembly also includes a mechanism for moving the at least one side feed wheel transversely relative to the at least one primary feed wheel to feed wood material to the at least one primary feed wheel of the wood chipper.

a waste processing machine for reducing wood waste comprises an accumulator operatively connected to the cutting system so as to power the cutting system upon discharge thereof. The accumulator is adapted to receive, store, and release a charge developed from a charging device operatively connected to the accumulator and one or more systems of the waste processing machine.

A cutter head includes first and second mounts that are configured to allow coupling with various motive equipment, such as a tractor or an excavator. The first mount may be mounted on the rear of the cutter head chassis for coupling with the tractor, while the second mount may be mounted on the top of the cutter head chassis for coupling with the excavator. A pressure gauge includes an adjustment arrangement such that the position of the display of the pressure gauge can be adjusted for viewing of the operator of the tractor or excavator. The cutter head may include a cooler assembly that works off or in conjunction with a primary cooler assembly of the tractor or excavator. The cutter head may include an excavator linkage equipped with a bushing assembly.

A waste reducing device, such as a wood chipper, having an infeed chute, a powered feed system, a powered cutting system, a discharge chute, and a safety device including an elongated structure positioned outside of and adjacent to the infeed chute of the wood chipper, the elongated structure movable vertically downward and radially inward towards the infeed chute between a plurality of positions, and an actuator operably connected to the elongated structure, the actuator having a plurality of operable positions corresponding to the plurality of positions of the elongated structure. The plurality of operable positions of the actuator permitting, interrupting, or reversing the motive operation of the powered feed and cutting systems of the wood chipper.

A cutting element for comminuting organic substances, organic materials, soils, plant cultures or the like, in particular for mulching, shredding and chopping, which cutting element can be connected fixedly or releasably to a comminuting rotor.

A removable blade mechanism for a plant material trimming device. The blade mechanism includes a blade bar connectable to the plant material trimming device and a tool-less adjustable locking device connectable to the blade bar and to the plant material trimming device to lock the blade bar to the plant material trimming device.

A method and apparatus for producing mulch. The apparatus includes a saw blade assembly having a cutter defining a cutting plane, and a clamp assembly for holding a log. The clamp assembly holds the log with its grain substantially parallel to the cutting edge. The apparatus further includes a movement means for repetitively moving the clamp assembly and saw blade assembly relative to each other so as to feed the saw blade assembly into the log while the grain remains substantially parallel to the cutting plane, so that the saw blade assembly removes thin, narrow strips of wood mulch from the log.

A yard waste chipper-shredder machine includes a reversible electric motor to drive a roller at low speed and high torque. The waste material is fed into an inlet chute and is crushed and ground into mulch between the roller and the chute for discharge through an outlet chute. The chute is spring biased to reduce jams. The machine operates quietly. Jams are quickly and easily removed by reversing the motor.

The invention relates to the municipal afforesting field, and specifically relates to a secondary-sweeping-free green plant trimming equipment for municipal afforesting and an implementation mode. Theequipment comprises a vehicle body, a top end shearing assembly, a lateral shearing assembly, walking wheels and a sweeping assembly, wherein the top end shearing assembly comprises a first cutting knife, a first lifting mechanism, a first rotary driving mechanism, a first cutting driving mechanism and a first horizontal displacement mechanism, and the first cutting knife can be used for trimmingthe top end of a green belt; the lateral shearing assembly comprises a second horizontal displacement mechanism, a second lifting mechanism, a second cutting driving mechanism and a second cutting knife; and the sweeping assembly comprises an annular dust collecting head and two slot-shaped dust collecting heads. By automatically trimming the green belt through the secondary-sweeping-free green plant trimming equipment, trimmed parts and twigs on the ground can be collected, so that the cleaning efficiency is improved, and the manual labor intensity can be decreased; and the angle of the first cutting knife can be adjusted, so that the aesthetic degree is increased, and efficient trimming of the green belt is realized.

A method and apparatus for enhancing safety in operating a brush chipper. A remote-enabled warning light flashes any time the brush chipper may be operated via a wireless remote control module. Workers on the ground are thereby notified the functions of the brush chipper may be changed in a manner not evident from their vantage point. Additionally, for remote operation to be enabled, two switches must both be in a remote-enable position and a feed control bar must be in neutral. Any change in these aspects will remove control from the remote module and make the machine controllable only at the controls on the brush chipper.

The invention discloses a labor-saving hedge trimming device convenient to adjust. The hedge trimming device comprises a vehicle body, a trimming blade and a collecting box; a sliding frame is provided with a sliding groove, a positioning mechanism is embedded in the sliding groove, and the positioning mechanism comprises a sliding block; a fixing frame is fixedly connected to the lower end of thesliding block, and a trimming cylinder is fixedly connected to the bottom of the fixing frame. According to the hedge trimming device, by the arrangement of the sliding frame with a horizontal part,an arc part and a vertical part and the trimming cylinder, the trimming position and the trimming angle can be conveniently adjusted through the positioning mechanism, and the trimming effect is improved; by the arrangement of the trimming cylinder, the trimming blade, a scraping plate and a discharging pipe tangentially communicated with the trimming cylinder, hedge branches can be efficiently trimmed and collected, and it is avoided that the branches fall everywhere; by the arrangement of the collecting box, a spiral blade roller and smashing blades, the branches are further smashed, the capacity of the collecting box is increased, and the smashed branches can be directly used as fertilizer to backfill soil in the later period.
