1. An agricultural application implement for delivering particulate product to a field, the implement comprising:
a frame;
a bin to hold product;
a pneumatic conveying system fixed to the frame, the pneumatic conveying system comprising:
an airflow source to provide an airflow, and
a delivery line operably connected to the airflow source and to the bin, the delivery line including a plurality of outlets; and
a metering system operably connected between the bin and the pneumatic conveying system, the metering system to meter product with the airflow to result in a mixed flow of airflow and product for the delivery line; and
a bin lift system comprising:
a first hydraulic cylinder and a second hydraulic cylinder operably coupled with a forward portion of the bin, the first hydraulic cylinder configured to extend or retract independently of the second hydraulic cylinder;
a third hydraulic cylinder and a fourth hydraulic cylinder operably coupled with a rearward portion of the bin, the third hydraulic cylinder configured to extend or retract independently of the fourth hydraulic cylinder;
four fasteners respectively coupling each of the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder to the bin, wherein the fasteners define a pivot axis that is perpendicular to the direction of travel of the implement; and
a bin lift controller to control the four hydraulic cylinders to raise or lower the bin.
