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.

A sieve arrangement for an agricultural combine harvester includes a sieve frame for carrying a sieve, a side shaker arm, and a plurality of elongate structural members. The sieve frame includes a first side frame member and a second side frame member. The side shaker arm is connected with the first side frame member. Each structural member has a first end connected to the side shaker arm, and a second end connected with the second side frame member.

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 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.

The combine system provides a motor driven paddle system for the movement of grain from combine storage, such as a hopper, to secondary storage, including but not limited to a grain bin, truck, or grain cart. The paddles are constructed from a somewhat rigid material that enable the paddles to move the grain to the secondary storage. The paddle conveyor may be partially enclosed by a housing that protects users from accidental contact with the paddles and the paddle conveyor.

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.
