A system and method for conveying agricultural material in a harvester. One harvester includes a rotor which rotates to separate a plant into a first agricultural material and a second agricultural material. A grate is disposed vertically below the rotor and further separates the first and second agricultural materials from one another. A first conveyor receives the first and second agricultural material directly from a trailing end of the rotor and a trailing end of the grate.

An agricultural harvester includes a chassis; a threshing and separating assembly carried by the chassis; and a chopper assembly carried by the chassis that receives crop material from the threshing and separating assembly. The chopper assembly includes at least one movable chopping knife; a plurality of counter knives movable between a first knife position and a second knife position, the plurality of counter knives configured to cooperate with the at least one chopping knife to cut crop material when in the first knife position; a shear bar movable between a first bar position and a second bar position; and a linkage assembly connected to the plurality of counter knives and the shear bar such that the linkage assembly is selectively actuable to simultaneously move the plurality of counter knives and the shear bar between their respective first and second positions.

A combine having a mobile frame and a harvesting header for removing crop material from the field and feeding it to a central location. A threshing and separating system separates grain from crop material and a feeder housing receives crop material from the harvesting head and conveys it to the threshing and separating system. A grain tank has a conveyor for transferring separated grain to the grain tank. Either of the harvesting header or the feeder housing has a perforated floor section sufficiently coarse to permit passage of grain to a conveyor beneath the perforated floor section that receives the grain and delivers it to either downstream of the threshing and separating system or the separated grain conveyor.

A combine harvester is provided that separates grain material from material other than grain using multiple processing areas, including a harvesting area, a feederhouse area, a threshing area, a cleaning area, and a grain delivery area. In a location at or prior to entering one of the processing areas, the material may be collected and held until a collection threshold is reached. Once it is determined that the collection threshold is reached, the material forming a first group of material may be transported from the location to the processing area or a subsequent processing area. The first group of material is transported from the location to the processing area or the subsequent processing area substantially simultaneously and thus simulates the gathering of a large amount of crop material even when small plots are involved. In this way, reduced cycle times may be achieved, and the efficiency benefits of large-plot harvesting may be extended to small-plot applications.

A set of sensor inputs are received in an agricultural machine. The sensor inputs are indicative of sensed or measured variables. A probabilistic control system probabilistically infers values for another set of variables and generates a set of control signals based on the probabilistically inferred values.

An agricultural combine including an agricultural harvester, a crop tank for harvested material, an unloading auger for unloading and discharging crop material. The auger assembly has first and second auger tubes pivotally connected to one another. The auger tubes pivot between a first position in which the auger tubes are coaxial and a second position in which the auger tubes form one of at least two angles. A first link is pivotally connected to the first auger tube and a second link pivotally connected to the second auger tube. An actuator is connected to one of the auger tubes and to one of the links, with the first and second links being pivotally interconnected at one of two positions to maintain the auger tubes in both auger tube positions without loading the actuator.
