A calibrating system for calibrating a metering system, the calibration system comprising:
- a work vehicle comprising:
- a commodity container;
- and
- a metering system, wherein the metering system comprises a metering element configured to dispense a commodity from the commodity container;
- a receptacle removably mounted to the work vehicle and positioned with respect to the metering system to receive the commodity from the commodity container metered from the metering element;
- a load cell configured to detect a weight related to an amount of commodity metered through the metering element;
- and
- a control system comprising at least one processor, the control system configured to:
- receive the detected weight from the load cell related to the amount of commodity metered through the metering element;
- determine a calibration factor for operating the metering element based on the detected weight;
- generate a control command for the metering element according to the calibration factor;
- and
- operate the metering element according to the control command.
A work vehicle comprising:
- a chassis;
- a commodity container supported on the chassis;
- a metering system comprising a metering element operable to dispense an amount of commodity from the commodity container;
- a receptacle, wherein the receptacle is removably mounted to the chassis and positioned with respect to the metering system to receive the amount of commodity from the commodity container metered by the metering element;
- a load cell configured to detect a weight of the amount of commodity metered through the metering element;
- and
- a control system comprising at least one processor, the control system configured to control operation of the metering element using a calibration factor.
A removable receptacle for collecting a commodity dispensed from a metering system of an air seeding cart, the removable container comprising:
- a collection body configured to be removably attachable to a chassis of the work vehicle, the collection body including an open end configured to receive a quantity of dispensed commodity;
- and
- a load cell attached to the collection body that detects a weight of the receptacle including a contents thereof.
