An electric trimmer has an electric motor and power source, a pair of blade plates, at least one of which is connected to an oscillator mechanism in the electric motor, and a pair of guard plates disposed one on each side of the at least one of the pair of blade plates, the guard plates hosting a matching radial or linear pattern of slots having a uniform spacing, a uniform slot width, the slots breaking out past at least one edge of the guard plates, the guard plates, in assembly, creating a gap space there between. One or more operators may insert branches having buds or flowers thereon through any one of the matching slots in the slot pattern, the branch oriented orthogonal to the blade set with the blade plates oscillating to harvest the buds or flowers within the gap space.

A system for removing biomass from a stem includes a frame, a conveyor mechanism which moves the stem in a horizontal conveying direction, a pair of rollers which exert a rubbing force between each other for removing the biomass from the stem, and a tensioning system arranged to exert a force which holds the stem to the conveyor mechanism. A first axial end of each roller is connected to an inlet end side of the conveyor mechanism, and a second axial end of each roller is connected to a transmission such that the rollers are angled downward from the first axial ends to the second axial ends. The conveyor mechanism moves the stem so as to pass between the rollers such that the rubbing force removes the biomass from the stem, and such that the rubbing force moves downward along the stem as the stem moves in the conveying direction.

To improve the comminution of the plant material cut off by a mulching device, a mulching device is provided comprising a rotor which can be rotated in a direction of rotation by means of a shaft and has movable blades, and comprising, with respect to the movable blades, counter-cutting elements that are fixed to the device, that cutting edges of the counter-cutting elements directed opposite to the direction of rotation have a corrugated shape, wherein, in their direction of extension, in particular the counter-cutting elements have at least two convex portions with one concave portion arranged therebetween. The cutting unit can be formed in one piece without any connection.

The present subject matter relates to systems, devices, and methods for agricultural sample collection. In one aspect, a sample collection system includes an aerial robotic platform, an arm assembly coupled to the aerial robotic platform and comprising an arm that extends away from the aerial robotic platform, and a sample collector connected to a distal end of the arm, wherein the sample collector is configured to selectively remove one or more samples of agricultural material from a plant to be analyzed.

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.

A vine removal device may include a shaft connected to a hook with a pocket. An actuation mechanism, such as a line connected to a user's belt, can actuate a movable jaw having a jaw projection configured to at least partly fit within the pocket. The hook has blade that supports a vine slide surface that facilitates collection of vines in the pocket where they can be gripped by the projection of the movable jaw. The blade may employ a surface skimmer to limit how deep the blade can penetrate the soil.

A material reduction machine includes an infeed portion operable to receive material to be reduced, and a cutting mechanism operable to reduce material fed in from the infeed portion. An outlet chute has a first end operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends along a curved path. The outlet chute includes, along a radially-inner side of the curved path, a foraminous interior wall providing communication with a sound attenuation layer.
