1. A seeder system for applying a granular input product to an agricultural field at variable rates between sections comprising:
- a product supply configured for storing the granular input product;
a plurality of product dispensers, each of the product dispensers of the plurality of product dispensers at respective sections of a plurality of sections of the seeder system;
a plurality of pneumatic lines configured to convey input product therethrough, each of the plurality of pneumatic lines are associated with the respective sections, and each of the plurality of pneumatic lines extends between at least the product supply and at least one product dispenser associated with the respective sections; and
a metering system including;
a plurality of metering wheels in communication with the product supply, each metering wheel of the plurality of metering wheels associated with the respective sections of the plurality of sections,a controller configured to independently control the rates of rotation of each metering wheel of the plurality of metering wheels relative to the rates of rotation of the other metering wheels, andwherein each metering wheel is configured to introduce the granular input product to respective pneumatic lines of the plurality of pneumatic lines according to the independently controlled rates of rotation, and each of the product dispensers is configured to dispense the granular input product at the respective sections according to the independently controlled rates of rotation.

Abstract
A metering device for an agricultural implement to apply a field input, for example, pneumatically delivered granular product including seed or fertilizer, to an agricultural field. the rate of application of dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

17. A method of dispensing granular input product from an implement, the method comprising:
-
dispensing the granular input product from a plurality of sections, the granular input product dispensed at independent dispensation rates at each of the sections of the plurality of sections; wherein dispensing the granular input product at the independent dispensation rate at each respective section of the plurality of sections includes; determining a rate of rotation of a metering wheel of the respective section, the rate of rotation corresponding to the independent dispensation rate, rotating the metering wheel at the selected rate of rotation to introduce the granular input product to a pneumatic line from a product supply, and conveying the granular input product through the pneumatic line to one or more product dispensers according to the independent dispensation rate and corresponding rate of rotation of the metering wheel; and repeating dispensing the granular input product at the independent dispensation rate for each metering wheel of a plurality of metering wheels, the rate of rotation of each metering wheel is independent of the rates of rotation of the other metering wheels. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
