Abstract
An agricultural product delivery applicator for delivering particulate product to a field. The applicator includes a bin having a first chamber to hold a first product, a second chamber to hold a second product, and a third chamber to hold a third product. The applicator further includes a pneumatic conveying system having an airflow source to provide an airflow, a delivery line operably connected to the airflow source and to the bin, and an outlet coupled to the delivery line. A metering system is operably connected between the supply compartment and the pneumatic conveying system. The metering system meters product with the airflow to result in a mixed flow of airflow and product. The metering system includes a novel hydraulic circuit for helping to meter the product.
