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.

A modular leaf shredder is provided. The modular leaf shredder includes a housing having a plurality of interlocking housing subsections. The modular leaf shredder further includes a trimmer connector adapted to form a physical connection with a cooperating member of a trimmer in order to physically join the housing to the trimmer. The head of the trimmer includes a rotating head having at least three sets of cutting wires, at least two sets of cutting wires being substantially perpendicular to each other.

A land preparation implement includes a rotatable drum assembly that includes a tool assembly. The tool assembly includes a tool holder and a tool. The tool includes a plurality of cleats. The tool holder includes a plurality of cleat supports. The cleats and the cleat supports cooperate to facilitate releasable coupling of the tool to the tool holder.

A computer-implemented method for reporting performance of an agricultural input for a plant involves: storing in a computer database a set of agricultural inputs, plants for which the agricultural inputs are used, performance attributes of the agricultural inputs, historical agricultural input performance values, and a relative significance of each of the agricultural inputs for the performance attribute. A computer processor is used to receive a plant selection; receive an attribute to be targeted for the plant selection; identify a plurality of agricultural inputs for affecting the targeted attribute for the plant using the historical agricultural input performance values; rank the plurality of agricultural inputs for affecting the targeted attribute for the selected plant using the relative significance associated therewith; and display the plurality of agricultural inputs and corresponding ranks for the received attribute associated with the selected plant.

An apparatus for the comminution of a botanical feedstock includes a vessel, a screen positioned in the vessel above a first feedstock outlet and spaced from the top of the vessel, and a blade rotatably mounted above and generally parallel to the screen. The blade has a leading side, a trailing side, and a radial blade length. At least a portion of the leading side has a cutting edge and at least a portion of the trailing side has a downwardly extending trailing portion. The downwardly extending trailing portion has a lower edge having a plurality of discontinuities along a radial length of the trailing portion. The cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.

Implementations include providing a baseline multi-dimensional model of a cultivar, determining an encoding based on the baseline multi-dimensional model, and a target multi-dimensional model, the encoding defining a string of symbols, and being based on an alphabet and a set of rules, providing an expected multi-dimensional model based on the encoding, and a modified set of rules, the modified set of rules being based on the set of rules, the expected multi-dimensional model representing the cultivar after a period of time, selecting a set of actions by determining multiple predicted multi-dimensional models for each set of actions in a plurality of sets of actions, and, for each predicted multi-dimensional model, providing a predicted yield that can be used to determine impact with respect an expected yield, the set of actions being selected based on a respective impact, and providing the set of actions as output for executing on the cultivar.

Exemplary embodiments of a chipper shredder are provided. In some exemplary embodiments, the chipper shredder can include a rotor disc having an obverse side and a reverse side, one or more chipper blades provided on the obverse side, one or more impeller blades provided on the reverse side, the one or more impeller blades being perpendicular to the rotor disc, one or more hammer blades on the reverse side, the one or more hammer blades being substantially parallel to the rotor disc, and one or more L-blades on the reverse side that extend outwardly and upwardly from a center of the rotor disc.

A rotary plant cutter, in one example comprising: a base frame; a drum supported by the base frame; a first disk mounted within the drum and fixed to the drum; the first disk having surfaces defining a plurality of radial slots through the first disk; a second disk mounted within the drum adjacent to and above the first disk; the second disk configured to rotate relative to the first disk about a rotational axis; a drive unit having a housing fixed to the drum; and the drive unit having a shaft coupled to rotate the second disk relative to the first disk.

A land preparation tool includes a tool body having a cutting surface, mounting surfaces disposed on the tool body opposite the cutting surface, and opposing side surfaces each extending between the cutting surface and a different one of the mounting surfaces. One mounting surface angles inwardly from a distal edge of a side surface toward the tool body. Another mounting surface angles inwardly from a distal edge of the other side surface toward the tool body. An opening is disposed on the tool body opposite the cutting surface and between the mounting surfaces. Other embodiments are described and claimed.
