A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about ⅜ inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.

A chain flail debarking apparatus including a flail chamber accommodating at least first and second rotatable flail shafts being supported on a movable flail assembly framework, and both of the first and second rotatable flail shafts having a plurality of chains, a disc chipper for receiving the debarked logs and trees from the flail chamber and generating wood chips having a desired shape and size, and a single drive for driving both the disc chipper and at least the first and second rotatable flail shafts in the flail chamber. A pivotable feed roller is located adjacent an inlet to the flail chamber for sensing a diameter of the logs and trees to be debarked and moving the movable flail assembly framework, relative to the base frame, so as to maintain the logs and trees being debarked in the flail chamber, substantially centered with respect to both the first and second rotatable flail shafts so that both upwardly and downwardly facing surfaces of the logs and trees being debarked are substantially equally treated.

A stump cutter includes an engine and a cutting wheel. A drive assembly is disposed between the engine and the cutting wheel. The drive assembly comprises at least one pulley. The at least one pulley defines a cylindrical recess therein. A drum brake assembly is configured to engage the cylindrical recess of the at least one pulley.

An adapter method and system includes a first side deflector, a second side deflector, and a top deflector coupled to the first side deflector and the second side deflector. The system may further include an internal deflector coupled to the first, second, and top deflectors. A first leg is coupled to the first side deflector and a second leg is coupled to the second side deflector. The legs are adjustable between a first position and a second position. The first, second, and top deflector define an entrance region for channeling wood-based debris into the chute of a woodchipper. Each side deflector may include a coupling mechanism for attaching to a woodchipper. Each coupling mechanism has an aperture. Each leg may telescope within a respective side deflector.

A chipping machine includes a debarking assembly, a chipper assembly, and a log advance system to conveys logs through the chipping machine and into contact with the debarking assembly and chipper assembly. A rotating chipper disk cuts chips from the log. A housing encloses the chipper disc and includes a spout that provides an exit path for chips out of the housing. The chipper assembly includes a first path for collecting bark and directing bark out of the machine. A second path that is separate from the first path collects trash and directs the collected trash to first path and out of the machine. An inlet of the second path is an opening formed in a base of the housing. The second path includes a chute onto which trash falls and then slides under the force of gravity to the first path.

A flywheel and paddle assembly for a chipping or shredding apparatus, including a wood chipper, a brush chipper, and a leaf shredder. The assembly has a flywheel attached coaxially to a drive shaft. The flywheel has at least one aperture extending from the front side to the back side, and carries at least one knife adjacent to the at least one aperture. The knife presents a knife edge on the front side of the flywheel. A paddle is rotatably mounted coaxially to the drive shaft adjacent to the back side of the flywheel. The paddle is configured to rotate on the drive shaft independently of the flywheel. A chipping or shredding apparatus incorporating the aforesaid flywheel and paddle assembly is also disclosed.
