A cutting element, in particular for abrasive cut material, is provided that includes a substrate that defines at least one cutting wedge which is formed by first and second wedge surfaces that intersect along a wedge edge. A cutting layer that extends over the first wedge surface and defines a cutting edge which lies on the wedge edge when new. The wear resistance of the cutting layer is greater than wear resistance of the substrate. The cutting layer is configured to define a blade-shaped protrusion that projects beyond the wedge edge due to wear of the substrate in the area of the second wedge surface to provide a self-resharpening cutting edge. The cutting layer or part thereof is formed by means of melt-metallurgical modification of an edge zone of the substrate by in-situ precipitation of finely dispersed inherent hard phases from partial melting of the edge zone of the substrate.

A forage harvester comprising an edge sharpness detection device for detecting a degree of edge sharpness of a cutting mechanism. The cutting mechanism comminutes a stream of harvested material, with a material inflow area being defined where the cutting blades interact with the shear bar to comminute the harvested material. The edge sharpness detection device excites one or more magnetic circuits, with the respective magnetic circuit being closed by the respective cutting blade during rotation of the cutter drum once one of the cutting blades passes the magnetic assembly. The edge sharpness detection device detects the magnetic flux in the respective magnetic circuit and, based on a detected change, determines a degree of edge sharpness of the respective cutting blade. Further, the magnetic flux of the magnetic circuit may be guided lengthwise in the cutting blade at least along a longitudinal section of the respective cutting blade.

A dual rotary cutter bale processor operable in a first mode for producing ground material and dispersing ground material for a first use and a second mode for producing cut material and dispersing cut material from the processor for a second use, where the cut material is coarser than the ground material. Material is processed for feeding into a container, bunk, or tire, into windrows on the ground, making piles of material, spreading the material for use as animal bedding, and/or mulching newly seeded areas. A screen and moveable bypass door for each rotary cutter and a position of a deflector direct a cut path such that the bypass doors can be used to force the material through the screens to further reduce size of the material or the deflectors can be used so the material bypasses the screens for dispersal from the processor in a coarser state.

Processing of baled material includes a bale opening stage, a separation stage, and a decortication stage. The bale opener features a conveyor moving incoming bales toward a toothed extractor with an array of teeth driven on a revolutionary path moving upwardly past the adjacent end of the conveyor to rake through the bale and extract material therefrom. The conveyor tilts upward reduce a working angle between the conveyor and the toothed extractor to urge the shrinking bale toward the moving teeth. A separation stage features multiple sets of vertically stacked, counter-rotating rollers with different characteristics from one set to the next. A decorticator has an external container, an internal drum rotatably supported therein, and an array of teeth on the drum. Driven rotation of the internal drum spins the fibrous stalks around the internal drum and impacts the fibrous stalks against surrounding interior wall surfaces of the external container.

An apparatus has a trailer with one or more wheels and a connector that connects the trailer to an automotive machine that mobilizes the trailer from a first position to a second position within a field of one or more plants. Further, the apparatus has a branch trimming device operably positioned on the trailer. Additionally, the apparatus has a conveyer belt operably positioned on the trailer. The conveyer belt receives a trimmed plant that has one or more branches trimmed off by the branch trimming device. The apparatus also has one more cutting devices. Finally, the apparatus has a tumbler that receives the trimmed plant from the conveyer belt and rotates with respect to the one or more cutting devices to cut the trimmed plant into the one or more buds. A bottom portion of the tumbler is positioned in proximity to the one or more cutting devices.
