A chopping assembly is configured to receive crop plants processed by an agricultural combine harvester. The chopping assembly includes an inlet and a plurality of blades rotatable about an axis. The plurality of blades is positioned downstream of the inlet. The chopping assembly also includes an outlet positioned downstream of the plurality of blades. The outlet is partially defined by a first wall and a second wall. The chopping assembly further includes an actuator coupled to the second wall. The actuator is configured to move the second wall relative to the first wall. A control processor is in communication with the actuator. The control processor is configured to receive a first signal corresponding to a condition representative of a characteristic of the crop plants. The control processor is also configured to generate a second signal operable to control the actuator based on the condition.

Disclosed is a harvesting combine rotor cage top cover assembly that includes an overhead roof formed from a substantially horizontal flat section and downwardly angled side sections. A series of substantially parallel vanes are located beneath the overhead roof. Each vane is formed from a substantially flat top section located against the roof horizontal flat section and downwardly laterally extending legs being angled on their sides and having an arcuate bottom. The sides of the vanes are rotatable about a central pivot for promoting or retarding the flow of material in the rotor cage.

A combine harvester includes a threshing unit for threshing picked-up crop to obtain grain, a driver assistance system, with a memory for storing data, for controlling the threshing unit, and a computing unit for processing at least the data stored in the memory. A sensor system ascertains at least a portion of the current harvesting-process state. A sensor configuration assigned to the sensor system is defined by the type and scope of operational sensors is stored or can be stored in the memory. A functional system model for at least a portion of the combine harvester is stored in the memory. The computing unit is designed to carry out an autonomous determination of a threshing-unit parameter based on the system model, and defines the system model forming a basis of the control of the threshing unit depending on the sensor configuration stored in the memory.

A procedure for collection and processing of weed seeds of the type which includes: a first step of collecting of a plant material; fourth step of threshing of the harvested material; a fifth step of separating of grains from material other than the grains; a sixth step of cleaning of the main material; a seventh step of transporting the main material to a discharge device; and an eighth step of storing the main material in an appropriate media. Also includes a second step of placing the material obtained by a thresher head assembly into at least one conveyor belt towards a trailer; a third step of transferring the plant material into a transport and hauling vehicle to a stationary processing plant; a ninth step of grinding the residues; a tenth step of introducing the MDG into densification device; and a tenth step of incorporating in a mixer the resulting grinding of the ninth step along with at least one supplement.

An adjustable vane system for use with a rotor cage of a threshing system of an agricultural harvester includes a vane. The vane includes: a generally helically curved inner profile; a surface being an outer profile that is opposite the inner profile and is generally helically curved over a portion of the vane, the outer profile being configured to be positioned closer to the rotor cage than the inner profile; and a flat portion located midway along the outer profile.

A cutting and threshing blade for a bush hog, wherein the blade has a trailing edge and a leading edge. At least a third of the leading edge of the upper-side of an elongate distal portion of the blade has a knife edge with a knife length that thickens toward the trailing edge. The trailing edge can have an upward air deflector. The bottom-side of the elongate distal portion has a threshing element, which includes a threshing block, which is a steel block having a block length that is comparable to the knife length and projects downward and substantially parallel to the knife edge. The rotating blades pummel growth carriers (i.e.; cob, husk) bearing seeds, grains, and kernels with enough force that they are released. The synergistic rotating knife edge and threshing block transform the bush hogging process from a cutting process to a cutting and threshing process.
