A data processor retrieves or accesses a reference bin level versus reference phase for a determined seed type. A measurement device, receiver, or phase measurement module measures an observed phase of a primary received signal. The data processor is adapted to determine an estimated bin level of seeds, where the estimated bin level is established as the reference bin level that corresponds to a respective reference phase that is closest in value to the observed phase.

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

On a harvester, unload conditions are detected to determine whether an unloading operation should be commenced. If so, once a receiving vehicle is in a target position relative to a spout, an unloading auger is automatically engaged to unload harvested material from a clean grain tank, through the spout, into the receiving vehicle. When stop criteria are detected, then the unloading auger is automatically disengaged.

A crop tank system has a crop tank for receiving harvested crop and a fill level sensor arrangement for detecting fill level information regarding the crop tank. The fill level sensor arrangement includes a radar sensor, which sends out and receives radar rays that, depending on the fill level of the crop contained in the crop tank, penetrate the crop contained in the crop tank and/or are reflected by the crop contained in the crop tank. The fill level sensor arrangement also includes an electronic sensor control, which determines the fill level information based on the received radar rays.

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 grain tank includes a generally flat bottom that is oriented at a position that is less than the angle of repose of the grain. A conveyor mechanism conveys grain along the bottom to a cross auger for unloading. One or more sensors may be placed in the grain tank to determine a state of the grain to further determine if the conveyor mechanism should be operated to unload grain from the grain tank.

A harvest production parameter capturing system for crop yield determination includes programming code, which is selectively installable on an electronic device and enables it for optical character recognition of text in an image of a display of a digital scale, thereby allowing determination of a weight of a load. The programming code enables the electronic device to display on its screen an interface allowing for entry of a plurality of parameters that characterize the load. Also included is a server, which is in communication with the electronic device allowing for transmission of the weight of the load and the parameters to the server, which writes them to data tables that are associated with a user. The server is programmed to perform data aggregation and analysis on the weight of the load and the parameters and to communicate results from the data aggregation and analysis to the electronic device.

A combine including a frame, power unit and a crop gathering and processing device. A grain tank is mounted on the frame. An elongated closed end tube is vertically oriented within the grain tank and has a plurality of uniformly spaced openings along its length. A pneumatic pump pressurizes the interior of the tube. A pressure sensor senses the interior pressure of the elongated tube, so that grain building up therein selectively covers the plurality of openings to cause a proportionate increase in air pressure.

A grain tank includes a generally flat bottom that is oriented at a position that is less than the angle of repose of the grain. A conveyor mechanism conveys grain along the bottom to a cross auger for unloading. One or more sensors may be placed in the grain tank to determine a state of the grain to further determine if the conveyor mechanism should be operated to unload grain from the grain tank.

An agricultural harvester includes a crop processor, a grain tank, an unload conveyor, and an electromagnetic detecting and ranging module positioned at or above a top of the grain tank for detecting a fill level of the grain tank and the location of a receiving vehicle relative to the combine harvester. One or more computing devices receive data from the electromagnetic detecting and ranging module, the data indicating the fill level of the grain tank and the location of the receiving vehicle relative to the combine harvester, and use the data to generate graphic data defining a graphical representation illustrating the relative positions of the unload conveyor and a grain bin of the receiving vehicle. An electronic device including a graphical user interface presents the graphical representation on the graphical user interface.
