Embodiments are directed to a plant trimmer. The plant trimmer may separate leaves or other peripheral plant matter from a body portion of a plant. In one aspect, an embodiment includes a rotatable basket having a set of ribs separated by openings in a basket sidewall and a cutting assembly having at least one blade. The rotatable basket may be configured to spin in a first direction. The cutting assembly may be configured to spin parallel to the rotatable basket and in a second direction, opposite the first direction. Plant matter extending through one of the openings in the sidewall of the rotatable basket maybe sheared by a cutting face of the blade and a rib of the rotatable basket.

A plant material trimming device includes two end walls supporting a rotatable perforated tumbler, a rotatable reel with helical blades, and a blade mechanism pivotably connected to the end walls of the device. The blade mechanism includes: (i) a blade bar configured to cut plant material in cooperation with the helical blades when the device is in operation; (ii) a first arm operatively associated with the blade bar; and (iii) a second arm pivotably connected to the first arm such that the second arm can pivot downward when the blade mechanism is unlocked. A tightening block may be threadedly connected to the second arm and connectable to one of the two end walls. The tightening block may be configured for adjusting the pitch of the blade bar relative to the helical blades when the blade mechanism is locked to the end walls.

A method for using a computer or computers to generate cut-point data including information indicating a three-dimensional position of a point on a cane of a fruit tree where the cane is to be cut off, includes, for each of one or more canes of the fruit tree, acquiring values concerning two or more attributes, including an attribute having different evaluation criteria depending on a cultivation method of the fruit tree and an attribute having unchanging evaluation criteria irrespective of a cultivation method of the fruit tree, based on sensor data including information indicating a three-dimensional structure of the one or more canes, determining the one or more canes each as a cane to be removed or a cane to be retained based on the measurement values, and generating the cut-point data for each cane determined as a cane to be removed.

A method for using a computer or computers to generate cut-point data including information indicating a three-dimensional position of a point on a cane of a fruit tree where the cane is to be cut off includes acquiring information on a cultivation method of the fruit tree, for each of one or more canes of the fruit tree, acquiring a measurement value(s) concerning one or more attributes including an attribute having different evaluation criteria depending on the cultivation method, based on sensor data including information indicating a three-dimensional structure of the one or more canes acquired by a sensor or sensors, determining the one or more canes each as a cane to be removed or a cane to be retained based on the measurement value(s), and generating the cut-point data for each cane determined as a cane to be removed.

A method for using a computer or computers to generate cut-point data including information indicating a three-dimensional position of a point on a cane of a fruit tree where the cane is to be cut off includes, for each of one or more canes of the fruit tree, acquiring measurement values concerning two or more attributes, including an attribute concerning buds on the cane and an attribute other than buds, based on sensor data of the one or more canes being acquired by a sensor or sensors, determining the one or more canes each as a cane to be removed or a cane to be retained based on the measurement values, and generating the cut-point data for each cane determined as a cane to be removed.

An agricultural machine working around trunks of plants includes a support structure, connectable to a vehicle or tractor, an arm connected to the support structure, providing movement relative to the support structure. An actuator system controls arm movements to selectively move a distal end of the arm towards or away from a trunk of a plant. An agricultural equipment is adapted to work around trunks of plants, connected to the arm's distal end. A safety system prevents the agricultural equipment from damaging trunks of plants. The safety system includes an idle wheel and a sensor. The sensor detects abutment of the idle wheel against the trunk. A control system controls the actuator system so the arm moves if the sensor detects the abutment of the idle wheel against the trunk, thus moving the distal end away from the trunk, preventing the idle wheel from exerting force against the trunk.

A method executed by a computing device includes forming tokenized words based on text that includes a query and associating individual tokenized words with information indicative of possible interpretations of the individual tokenized words. The method further includes generating one or more equation packages based on respective permutations of the possible interpretations and selecting a surviving equation package of the one or more equation packages based on at least some of the relationship information described in the one or more equation packages. The method further includes generating, based on the surviving equation package of the one or more equation packages, a response to the query.
