Abstract

A system for maintaining an appropriate air flow in an air stream in an air seeder. A fan provides an air stream to carry agricultural materials for distribution across a width of a seeding implement. A tank contains a granular agricultural material and a metering device dispenses the material into the air stream. The system is calibrated such that a known weight of material is dispensed for each revolution of the metering device whereby the rotational speed of the metering device multiplied by the known weight per revolution results in a known per minute rate of agricultural material being dispensed into the air stream. A
microprocessor is programmed to derive an appropriate fan speed for the per minute rate of agricultural material being dispensed and send a signal to a fan control to adjust the speed of the fan to correspond to the appropriate fan speed.
