Patent ID: 8151719

Claim:
A method of distributing at least one product on a ground surface with a drill having two sets of seeding units connected to a distribution system, the method comprising: selecting a desired distribution pattern between a separate pattern, where a first one of the at least one product is distributed through only a first one of the sets of seeding units in spaced apart rows, and a mixed pattern, where the first product is distributed through both the sets of seeding units in spaced apart rows; providing a distribution system defining a communication between the two sets of seeding units and at least one reservoir of the drill containing the at least one product; when the separate pattern is selected, configuring first and second sections of the distribution system such that only the first section is in communication with the first one of the sets of seeding units, and receiving the first product from the reservoir in the first section for distribution through only the first one of the sets of seeding units; and when the mixed pattern is selected, configuring the first and second sections of the distribution system such that the first section is in communication with both the sets of seeding units, and receiving the first product from the reservoir in the first and second sections for simultaneous distribution through both the sets of seeding units.
