In one aspect, a wheel assembly configured for use with an agricultural implement. The wheel assembly includes a wheel comprising an outer ground-engaging element and an inner hub extending radially inwardly from the outer ground-engaging element. The wheel defines an internal cavity radially inwardly relative to the outer ground-engaging element. The wheel assembly further includes a sensor positioned within the internal cavity of the press wheel.

A metering device and a distributing machine for metering free-flowing bulk material, in particular seeds and/or fertilizer, from a container, using a metering device. The metering device includes a delivery channel with an inlet and a metering outlet, and a pressure compensation section disposed in the delivery channel between the inlet and the metering outlet. The pressure compensation section is actuated by a pressure difference between the delivery channel and the surroundings.

A method for identifying a flow of commodity through a commodity distribution system. The method including providing a tank configured to contain a commodity, selectively distributing commodity from the tank to a drill assembly to be distributed to an underlying surface, and monitoring the flow of commodity from the tank to the drill assembly with a camera to identify flow characteristics.

An agricultural machine includes a frame, an arm pivotally coupled to the frame at a first end of the arm, and a target element on the first end of the arm. The target element is configured to rotate with the arm, and includes an outer surface and a projection extending away from the outer surface. The agricultural machine also includes a first sensor fixed to the frame. The first sensor is configured to detect the outer surface. The agricultural machine also includes a second sensor fixed to the frame. The second sensor is configured to detect the projection.

A metering system includes a plurality of metering elements that are independently controllable. A calibration method of the present disclosure includes generating calibration factors for the individual metering elements. Also, a method of the present disclosure includes operating the metering elements according to the respective calibration factor.

A system for re-calibrating a machine includes an arm having a first end and a second end opposite the first end. The arm is configured to be coupled to a frame of the machine and to move within a range of motion during an active state of the machine. The system includes a target element on the first end of the arm, the target element including an outer surface and a projection extending away from the outer surface. A portion of the outer surface defines an eccentric surface along the target element. The system includes a magnetic field sensor coupled to the frame and configured such that the sensor is operable to detect the projection 1) in response to the arm being positioned outside of the range of motion and concurrently 2) when the machine is not in the active state.

A metering system includes a plurality of metering elements that are independently controllable. A calibration method of the present disclosure includes generating calibration factors for the individual metering elements. Also, a method of the present disclosure includes operating the metering elements according to the respective calibration factor.

A collection device has a chute supported below the calibration opening on pneumatic delivery lines through which seed can be dispensed during calibration of a seed meter below a seed tank of an agricultural air seeder implement. The chute has a top opening at a top side in alignment with the calibration opening thereabove so as to receive seed discharged through the calibration opening into the chute through the top opening and a bottom that slopes downwardly to one end locating a discharge opening through which collected seed is dispensed. The chute is supported on bag mounts of the implement from which a flexible calibration bag is otherwise suspended. A gate is operably associated with the discharge opening.

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.

An example container for collecting bulk material dispensed from a meter during a calibration operation may include a canister comprising an open end to receive bulk material, a coupler configured to releasably couple to a meter, and at least one weight sensor extending between the enclosure and the coupler. The weight sensor may be configured to detect weight of the bulk material deposited into the enclosure via the open end.
