A brush chipper assembly has a housing and a feeder subassembly connected to the housing. The feeder subassembly includes opposed, first and second feeder rollers. When the feeder subassembly is actuated, the first feeder roller is operable to rotate in a first direction and the second feeder roller is operable to rotate in a second direction (opposite to the first direction) so as to draw the brush into the housing. Also provided is a chipping subassembly substantially contained within the housing behind the feeder subassembly. The chipping subassembly including first and second, opposed chipping heads, each of which carrying cutting teeth for chipping the brush. When the chipping subassembly is actuated, the first chipping head is operable to rotate in a third direction and the second chipping head is operable to rotate in a fourth direction (opposite to the second direction).

A winch boom system and method includes a frame, a shaft supported by the frame, and a winch drum attached to the shaft such that rotation of the shaft about a shaft axis rotates the winch drum. A boom is pivotably coupled to the frame, the boom defining a cavity in which the winch drum is positioned. A winch rope is wound about the winch drum, passing through the cavity of the boom, and extending from the boom at a point distal from the winch drum.

The present disclosure is directed to an apparatus and related methods (i.e. utilities) for trimming plants, in particular, buds and flowers, to remove unwanted plant material. A typical application would be to process a plant to leave only trimmed buds and flowers for use in potpourri, fragrant sashes, or as a prelude to further processing of essential oils. The utilities enable faster and safer production of plant material than prior plant processing machines. The utilities employ a coaxial drum and cutting element that counter rotate. This coaxial cutting element typically includes a plurality of cutting elements, to create a plurality of cutting interface that shear unwanted plant material form plant material within the drum and then collect this debris though, for example, a vacuum system. The use of the counter-rotating cutting interfaces allows for multiplying the cutting interfaces over prior existing machines.

An organic material and plant vine chopper assembly has two plant vine chopper rotor drum assemblies that chop plant vines and other organic material. Each rotor drum assembly has a plurality of rotor rings each ring having a plurality of angled blades that effectively cooperate with each other to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum. Each chopper rotor drum assembly incorporates a plurality of rotor rings spaced along and encircling and attached to a main drum tube and distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each rotor ring having a pair or a plurality of pairs of cutting blades attached to respective alternately angled mounting tabs that alternate to the left and to the right to the general plane of the rotor ring.

A processing system comprising at least one cylindrical tumbler having a base portion with one or more sidewalls extending upward, where the tumbler tumbles plant material placed inside, and where the tumbled material is trimmed within the tumbler. A motor is in communication with a power source and is mechanically coupled to the base of the tumbler, so that the motor rotates the tumbler. The one or more sidewalls have a plurality of apertures configured to selectively allow one or more plant byproducts to pass through.

A land preparation tool includes a tool body having a cutting surface, a mounting surface, an opening, and a channel. The cutting surface has a blade positioned at a distal end thereof. The mounting surface has a non-planar profile and is disposed on the tool body opposite the cutting surface. The opening is disposed on the mounting surface and the channel extends from the opening at least partially into the tool body. Other embodiments are described and claimed.

An infeed system is provided for a chipper or grinder having a processing portion wherein an item is processed into smaller pieces. The infeed system is upstream of the processing portion and includes a feed roller, a first hydraulic motor in communication with the feed roller for selectively actuating the feed roller, a second hydraulic motor in communication with the feed roller for selectively actuating the feed roller, and a hydraulic pump for providing hydraulic fluid to the first and second motors. A directional control valve and a relational control valve are between the pump and the motors. The directional control valve allows the hydraulic fluid to operate the first and second motors in a forward direction and in a reverse direction, and the relational control valve allows the hydraulic fluid to operate the first and second motors in series and in parallel.

A land preparation tool includes a tool body having a longitudinal axis; a cutting surface having a distal end and a blade positioned at the distal end; a mounting surface disposed on the tool body opposite the cutting surface, the mounting surface having an apex extending along about half of the mounting surface parallel to the longitudinal axis, a first mounting surface extending from the apex, a second mounting surface extending from the apex, and an opening disposed on the mounting surface; and a channel extending from the opening only partially into the tool body

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.

An organic material and plant vine chopper assembly has two plant vine chopper rotor drum assemblies that chop plant vines and other organic material. Each rotor drum assembly has a plurality of rotor rings each ring having a plurality of angled blades that effectively cooperate with each other to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum. Each chopper rotor drum assembly incorporates a plurality of rotor rings spaced along and encircling and attached to a main drum tube and distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each rotor ring having a pair or a plurality of pairs of cutting blades attached to respective alternately angled mounting tabs that alternate to the left and to the right to the general plane of the rotor ring.
