A utility work device includes a main body section supported by a support and a working section supported by the main body section to perform a work on an object. The main body section is movable in a horizontal direction and a perpendicular direction.

A land preparation tool includes a cutting surface having a blade and a mounting interface opposite the cutting surface. The mounting interface of the land preparation tool is configured to detachably connect to a tool holder having a top surface, an end surface, a mounting surface opposite the end surface, and opposing first and second side surfaces extending between the end surface and the mounting surface. The mounting surface has an apex extending downwardly from the top surface and first and second mounting faces. The first mounting face extends inwardly from the first side surface toward the apex and the second mounting face extends inwardly from the second side surface toward the apex.

Plant treatment systems and methods are presented. The system comprising a plant treatment apparatus comprising: one or more treatment channels and at least one plant treatment device associated with said one or more treatment channels, said at least one plant treatment device being configured and operable to controllably generate a force field and apply the force field to at least a portion of a plant, said force field comprising at least one pulse, wherein each pulse has a fast rise time, certain duration and amplitude profile, thereby inducing a vibration pattern in the at least portion of the plant, said vibration pattern being characterized by a plurality of vibration frequencies above a predetermined value, to thereby apply treatment to said at least portion of the plant; a sensing system comprising one or more sensors configured and operable to provide sensing signals indicative of a condition of said at least portion of the plant and feedback signals indicative of said vibration pattern, said one or more sensors comprising an optical sensor configured and operable to provide the sensing signals and/or feedback signals indicative of image data of said at least portion of the plant. A control system is configured and operable for data communication with said plant treatment apparatus, to receive and process the sensing signals and/or feedback signals produced by the sensing system, the processing of the sensing signals and/or feedback signals comprising determining the condition of said at least portion of the plant and/or said vibration pattern and operating said at least one plant treatment device to apply and/or adjust said force field to thereby induce the vibration pattern corresponding to the treatment of said at least portion of the plant.

A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a drive train for driving the rotor, the drive train including: a drive shaft connected to the rotor; a motor comprising a motor shaft; and a removable wear gear connecting the motor shaft and the drive shaft, wherein the wear gear is formed from a material that is softer than a material of the drive shaft or motor shaft.

A system and a method for automated sorting and trimming a plant. The system includes a trimming station, adapted to identify undesired portions of the plant, and to trim the undesired portions off the plant. The system may further include a guiding assembly adapted to ensure that the plant is aligned with the trimming station. A controller controls operation of the trimming station and of the guiding assembly. The system may further include a sorting station adapted to determine whether the plant is infected or contaminated. The controller may be adapted to control operation of the sorting station.

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.

An apparatus and method for separating plant flowers from stalks by means of a lateral rotating tube having a plurality of flexible, elongated members affixed to and extending radially outward from the tube. The apparatus may include a platform and a frame supporting the tube above the platform to accommodate plants held between the platform and the tube so that when the tube is rotating, the elongated members affixed thereto brush against the plants and cause the flowers to brush off at and separate from the stalks. The frame further supports a housing to form a contained space, with a hood to direct the flow of flowers after separation from the stalks. The back wall is positioned a distance away from the platform to allow separated flower and stalk to be eliminated from the apparatus.
