An agricultural vehicle includes: a chassis; at least one cleaning sieve carried by the chassis; a grain tank carried by the chassis; an unloader carried by the chassis and configured to unload crop material; and a crop material conveyor carried by the chassis and including a housing having a sieve inlet under the at least one cleaning sieve, a tank outlet coupled to the grain tank, an unloader outlet coupled to the unloader, and an endless conveyor within the housing, the crop material conveyor being configured to switch between a tank feed mode where crop material is conveyed by the endless conveyor out the tank outlet and an unload mode where crop material is conveyed by the endless conveyor out the unloader outlet.

One or more information maps are obtained by an agricultural system. The one or more information maps map one or more characteristic values at different geographic locations in a worksite. An in-situ sensor detects a material dynamics characteristic value as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that predicts a predictive material dynamics characteristic value at different geographic locations in the worksite based on a relationship between the values in the one or more information maps and the material dynamics characteristic value detected by the in-situ sensor. The predictive map can be output and used in automated machine control.

An agricultural harvester is described, the harvester comprising a processor for receiving a flow of harvested crop and processing the harvested crop, an on-board tank for storing the processed crop, and a loading arrangement for transporting the flow of processed crop from the feeder to the on-board tank. The loading arrangement comprises an auger, the auger comprising a lower section with an inlet for receiving the flow of processed crop and an upper section with an outlet. The auger further comprises a tubular housing and an auger fighting mounted inside the tubular housing for, during use, transporting the flow of processed crop from the lower section to the upper section and outputting the processed crop via the outlet of the upper section. A clearance between the housing and the auger fighting is larger in the lower section of the auger compared to the upper section.

An improved self-propelled grain harvester and threshing machine characterized by the sieves, cleaning fan and grain tank being beneath the grain harvester's threshing system which puts the center of gravity in the bottom of the machine and eliminates the need for conveying the grain throughout the machine for cleaning and to the top of the machine for storage. This configuration eliminates several clean grain conveying systems and reduces the length of the reprocess tailings elevator giving the machine a safe low profile and center of gravity when the machine is empty and the center of gravity lowers as the grain tank fills.

A bubble-up auger for a combine harvester includes a rotatable shaft, a lower auger section either mounted to or forming part of the rotatable shaft, and an upper auger section that is removably connected to the lower auger section, and includes an opening through which the shaft is at least partially positioned. The upper auger section is moveable between a first position where the upper auger section is detached from the lower auger section and a second position where the upper auger section is connected to the lower auger section.

A combine for reaping culms in a field while traveling, and accumulating, in a grain tank 2, grains obtained by threshing reaped culms, includes: a yield calculator for calculating a yield per unit of travel, which is a yield per unit of travel distance; a work travel determiner 53 for determining non-harvest work travel that does not involve grain harvesting, and harvest work travel that involves grain harvesting; a harvest map data generator 66 for generating harvest map data in which the yield per unit of travel, a travel route on which the combine has traveled in a field, and a result of determination performed by the work travel determiner are associated with one another; and a harvest information recorder for recording the harvest map data.

A grain management system includes a combine and a management server 8. The combine includes a grain measurer 30 for outputting a measured value related to a component of harvested grains supplied to a grain tank 16, and a data transmitter 51a for transmitting the measured value and field identification information for specifying the field to the management server 8 via a communication line. The management server 8 includes a receiver 81b for receiving the field identification information and the measured value from the combine, a table manager 83 for determining a measured value-grain component value table for deriving a grain component value using the measured value based on the field identification information, and a grain component value computer 82 for obtaining the grain component value based on the measured value, using the measured value-grain component value table that is determined by the table manager 83.

A harvesting machine includes: a crop tank; a measuring device that measures an amount of crop that has been stored in the crop tank; an unloader apparatus that discharges crop that has been stored in the crop tank; a device control part that executes precise measurement oriented device setting processing; a measurement control part including a precise measurement execution part that performs, precise measurement which involves the precise measurement oriented device setting processing, and a simplified measurement execution part that executes, simplified measurement; an operational instruction processing part that outputs a precise measurement instruction and a simplified measurement instruction in response to an operation performed by a manual operation device; and a measurement result recording part that rewrites a simplified measurement result recorded based on a preceding simplified measurement instruction, with a precise measurement result that is based on a succeeding precise measurement instruction.

A combine harvester includes a conveyance mechanism for conveying grains obtained by a thresher for threshing grain culms reaped from a field to a grain tank, a measurer (340) for measuring the amount of grain conveyed to the grain tank as a conveyed yield, a yield assignment calculator (631) for calculating a minimal section yield, which is a yield per minimal section, by assigning the conveyed yield to a minimal section in the field, a grain conveyance state detector (632) for detecting a grain conveyance state of the conveyance mechanism (7), a yield corrector (633) for correcting the minimal section yield in accordance with the grain conveyance state, and a yield distribution data generator (661) for generating yield distribution data that represents a yield distribution in the field, based on the minimal section yield.

A combine unload control system having a grain tank for storing grain and at least one auger for unloading grain from the grain tank. The control system also includes a first auger cover proximate to the at least one auger, having one or more first auger cutouts disposed on a portion of the first auger cover and a second auger cover proximate to the at least one auger and having one or more second auger cutouts disposed on a portion of the second auger cover. The control system further includes a controller configured to control amounts of grain to pass through the one or more first auger cutouts and the one or more second auger cutouts and flow to the at least one auger by causing the first auger cover and the second auger cover to move relative to each other.
