Granular spreader section control

摘要

This application discusses, among other things, granular spreaders. In an example, a granular spreader can include a blower configured to provide a flow of air, a metering device configured to provide a flow of granular material to the flow of air to provide a hybrid flow of air and granular material, a plurality of sections configured to release the granular material using the flow of air, wherein each section is configured to release an adjustable portion of the hybrid flow and a controller. The controller can be configured to receive control information for each section, to enable or disable each section responsive to the control information, and to adjust a speed of the blower based on the control information.
