An agricultural machine includes a cutting assembly configured to cut a crop material, a forming assembly comprising at least one of a swathboard or a forming shield, at least one actuator configured to change a position of the forming assembly, a sensor configured to detect a yield and a moisture content of the crop material, and a controller in communication with the at least one actuator, wherein the controller is configured to change an operating parameter of the agricultural machine responsive to the detected yield and moisture content. Related methods include propelling the agricultural machine through a field, cutting a crop material with the cutting assembly, detecting a yield and a moisture content of the crop material with the sensor, and changing an operating parameter of the agricultural machine responsive to the detected yield and moisture content.

A forage harvester includes a shear bar and a panel that directs the crop material downstream of the shear bar. A processing component is disposed downstream of the panel. An impact sensor is coupled to the shear bar and operable to detect data related to a magnitude of a force applied to the shear bar. The panel is moveable from a first position to a second position. The first position of the panel forms a channel for directing the crop material in the direction of crop processing along a first path toward the processing component. The second position of the panel alters the channel to direct the crop material along an alternative path not including the processing component. In response to a sufficiently high impact force applied to the shear bar by debris moving with the crop material, the panel is moved from the first position to the second position.

A crop head for a harvester includes a folding frame having a first frame portion and a second frame portion configured to be folded in a transport state and unfolded in a harvesting state. The first and second frame portions are lockable with respect to each other to inhibit folding and unlockable with respect to each other to allow folding. A plurality of crop dividers is supported by the first frame portion. The plurality of crop dividers includes at least one movable crop divider that is movable with respect to the first frame portion. The crop head also includes a cylinder and a piston movable with respect to the cylinder. The piston is operable to move the movable crop divider between the first and second positions and is configured to directly engage the first and second frame portions to lock the first and second frame portions with respect to each other.

An extractor for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a fan, a leaf shredder, and a hub. The fan comprises fan blades to induce a flow of air to separate leaves from billets. The leaf shredder comprises shredding blades to cut leaves prior to their ejection from the extractor. The hub is rotatably driven about an axis of rotation. The fan blades and the cutting blades are coupled to the hub for rotation together with the hub about the axis of rotation.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

An extractor is disclosed for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a fan and a leaf shredder. The fan comprises fan blades mounted for rotation about an axis of rotation to induce a flow of air to extract leaf material from billets produced by the sugarcane harvester. The leaf shredder comprises shredding knives mounted for rotation about the axis of rotation to shred leaf material prior to its ejection from the extractor. The leaf shredder is positioned below the fan or upstream from the fan relative to the flow of air.

An extractor is disclosed for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a housing, a fan positioned within the housing and comprising fan blades mounted for rotation in a rotational path about an axis of rotation to induce a flow of air to extract leaf material from billets produced by the sugarcane harvester, and a leaf shredder positioned within the housing and comprising shredding knives fixed against rotation about the axis of rotation, the shredding knives offset axially from the fan blades relative to the axis of rotation in proximity to the rotational path of the fan blades such that the fan blades and the shredding knives cooperate to shred leaf material by shearing action as the fan blades rotate past the shredding knives about the axis of rotation.
