Abstract: 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.

Abstract: 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.
