Abstract
A system for distributing particulate material from an agricultural machine includes a fan configured to provide an airflow in a supply line for distributing particulate material, a hydraulic system configured to drive the fan at a plurality of fan speeds, and a control system configured to control the hydraulic system. The control system executes a program stored in a non-transient medium operable to: determine a given product application rate for distributing the particulate material; determine a given ground speed of the agricultural machine; determine a fan speed for achieving the given product application rate at the given ground speed; and control the hydraulic system to drive the fan at the fan speed.
