A method of calibrating a metering system having a plurality of meter modules. Each of the meter modules includes an auger in communication with a product, the auger is driven by an electric motor. The method includes loading the auger with the product, discharging a metered quantity of the product from the auger by actuating the electric motor to drive the auger at a predetermined rotational speed for a predetermined number of auger revolutions. The discharged metered quantity of the product is captured with the capture structure. A load cell generates a signal magnitude correlating a known mass to obtain a derived mass value. A controller calculates a mass per auger revolution (MPR) value. The MPR values of each of the plurality of meter modules is summed and stored in memory. A derived application rate is calculated and compared to the derived application rate.

An apparatus to be coupled to sowing devices provides for precision in volumetric metering and distribution of solid agricultural inputs, said apparatus comprising a supporting, hollow housing with a through-hole through which an actuating through axle radially locked to a metering distribution centrifugal turbine extends, and drives the metering distribution centrifugal turbine; and an opening in the floor of the housing leading the agricultural input to an output nozzle. The metering distribution centrifugal turbine comprises cutouts of various shapes forming metering chambers for distributing the agricultural solid input uniformly. A labyrinth is formed by the supporting, hollow housing, the inner grater travel stop and the metering distribution centrifugal turbine. The metering distribution centrifugal turbine allows metering of the solid agricultural input only upon rotation of the metering distribution centrifugal turbine; when the metering distribution centrifugal turbine does not rotate the agricultural solid input is retained in and on the turbine.

A row unit for a seeding machine. The row unit includes a frame, a furrow opener coupled to the frame, and a position sensor assembly having a position sensor configured to detect wear of the furrow opener.

A metering device for dispensing agricultural product from a bin. The metering device comprises an upper housing and a lower housing removably engaged with the upper housings. The metering device further includes at least one metering wheel positioned within an interior space presented by the upper housing or the lower housing.

A method includes performing a plurality of calibration routines in which a metering element operates at different speeds. The method also includes receiving a respective plurality of measurements of commodity amounts metered out during the calibration routines. The method further includes generating a calibration factor for operating the metering element based on data generated from the measurements taken from the calibration routines. Also, the method includes generating a control command for the metering element according to the calibration factor. The method additionally includes operating, by the control system, the metering element according to the control command.

In one aspect, a calibration method for a seed meter may include controlling an operation of a singulator to apply an initial aggressiveness setting for the singulator. The method may further include controlling the seed meter to rotate a seed transport member of the seed meter relative to a seed chamber of the seed meter containing a plurality of seeds. The method may additionally include performing a calibration cycle, which may include monitoring a first parameter indicative of a number of occurrences of seed multiples as the seed transport member rotates, iteratively adjusting the aggressiveness setting from the initial aggressiveness setting as the first parameter is being monitored, and when the first parameter crosses a first threshold, recording the associated aggressiveness setting as a minimum aggressiveness setting for the singulator.

In one aspect, a calibration method for a seed meter may include controlling an air pressure source to apply an initial air pressure to a seed transport member of the seed meter defining a plurality of seed cells. The method may further include controlling the seed meter to rotate the seed transport member relative to a seed chamber of the seed meter containing a plurality of seeds. The method may additionally include performing a calibration cycle for the seed meter, which may include monitoring a first parameter indicative of a number of empty seed cells as the seed transport member rotates, iteratively adjusting the air pressure from the initial air pressure as the first parameter is being monitored, and when the first parameter crosses a first threshold, recording the associated air pressure as a minimum air pressure for the seed meter.

An agricultural implement for distributing fertilizer to a plurality of rows includes a fertilizer container, a plurality of fertilizer metering units, and a plurality of motors. The fertilizer containers are used for storing the fertilizer prior to the fertilizer being distributed to the soil. The plurality of fertilizer metering units each include a housing and a metering device positioned in the housing. The housing has an inlet configured to receive fertilizer from the fertilizer container and an outlet. The plurality of motors are each drivingly coupled to and configured to rotate at least one metering device to distribute fertilizer to a row of the plurality of rows.

A method and system for calibrating the feed rate of a metering device for airflow-borne feeding of granular material in an agricultural implement. The method of calibrating the feed rate of the metering device comprises a first volumetric feeder with a first metering rotor arranged to feed granular material to an airflow channel.

An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. A flow meter senses a flow of liquid applied to the field. The valve control signals are generated, based on the row pressure, and the sensed flow.
