A mobile chipper shredder includes a removable fin plate positioned within the rotor chamber. The removable fin plate includes a main body that has an arcuate shape and a plurality of fins that extend toward a rotor assembly from the main body. The fins are spaced on the main body so as to not interfere with paths of travel of a plurality free-swinging shredding hammers of the rotor assembly within the rotor chamber. The plurality of fins radially overlap at least one path of travel of the plurality of free-swinging shredding hammers.

A material reducing machine includes a rotary reducing drum that is rotatable about an axis of rotation and defines a reducing boundary that extends at least partially around the axis of rotation. The material reducing machine includes an infeed conveyor for transporting material to a front portion of the rotary reducing drum and defines a conveyor plane. The material reducing machine includes a mill box at least partially surrounding the rotary reducing drum and including a mill box lid mounted generally above the rotary reducing drum. The mill box lid has an inlet edge positioned above a rear portion of the rotary reducing drum and an outlet edge positioned above the front portion of the rotary reducing drum. The mill box includes an infeed opening that is configured to receive material from a feed table and has an upper opening defined by the outlet edge of the mill box lid.

A paper shredder support assembly for positioning a shredder above a receptacle includes a plate. A plurality of tubes is coupled to and extends from a bottom of the plate. Each tube comprises a plurality of nested sections so that the tube is selectively extensible. The plurality of tubes is positioned to support the plate over a receptacle. An opening is positioned in the plate. A shredder is positioned in the opening and is coupled to the plate. The shredder is configured to shred items that are inserted into the shredder so that shredded waste is expelled into the receptacle. A panel is selectively couplable to the plate to cover the opening.

A mulching and chipping attachment includes a deck having a top plate. A cutting disk is attached to the deck. The top plate includes an opening that exposes a portion of the cutting disk. A guide chute is attached to the deck, and is disposed over the opening. The guide chute includes a feed system. The feed system includes a first roller, and a reactionary member operable to react against the first roller to secure a log therebetween. The first roller and the reactionary member cooperate together to grasp and controllably feed the log through the opening. The first roller or the reactionary member may be moveable relative to the other, to adjust a throat distance therebetween. An anvil may be disposed at a rearward edge of the opening, and extend downward to define a chip cutting height between the anvil and the cutting disk.

A plant processing system may include a plant stripping apparatus with a frame and a plurality of stripping fingers including at least two groups of the stripping fingers being movable relative to each other. Each group of fingers may extend from a respective working surface, and the working surfaces may be oriented in substantial opposition to each other with a gap being formed between the first and second working surfaces to provide a pathway for movement of plant materials between an input and an output of the stripping apparatus.
