Abstract
A pneumatic distribution system for an agricultural implement, including a plurality of fluid lines including a primary fluid line and at least two secondary fluid lines, and at least one header fluidly coupling the primary fluid line with the at least two secondary fluid lines. The at least one header includes a header body having a fluid inlet fluidly coupled to the primary fluid line and at least two fluid outlets fluidly coupled to the at least two secondary fluid lines, a top cover connected to the header body, an insert located beneath the top cover and associated with the fluid passageway, and at least one actuator operably coupled with the insert and configured for moving the insert to control the airstream.

A pneumatic distribution system for an agricultural implement, comprising:
- a plurality of fluid lines including a primary fluid line and at least two secondary fluid lines;
- and
- at least one header fluidly coupling the primary fluid line with the at least two secondary fluid lines, and including:
- a header body having a fluid inlet fluidly coupled to the primary fluid line and at least two fluid outlets fluidly coupled to the at least two secondary fluid lines, and the header body defining a fluid passageway for allowing an airstream to flow therethrough;
- a top cover connected to the header body;
- an insert located beneath the top cover and associated with the fluid passageway;
- and
- at least one actuator operably coupled with the insert and configured for moving the insert to control the airstream.

- a top cover connected to the header body;
- a rigid insert located beneath the top cover, slideably connected to the header body, and associated with the fluid passageway;
- and
- at least one actuator pivotally coupled with the rigid insert and configured for moving the rigid insert to control the airstream.
A method for distributing a particulate matter in an agricultural implement, comprising the steps of:
- providing a pneumatic distribution system including a plurality of fluid lines including a primary fluid line and at least two secondary fluid lines and at least one header fluidly coupling the primary fluid line with the at least two secondary fluid lines, and including a header body having a fluid inlet fluidly coupled to the primary fluid line and at least two fluid outlets fluidly coupled to the at least two secondary fluid lines, and the header body defining a fluid passageway for allowing an airstream to flow therethrough, a top cover connected to the header body, an insert located beneath the top cover, connected to the header body, and associated with the fluid passageway, and at least one actuator operably coupled with the insert;
- maintaining the insert in a neutral position by maintaining a neutral state of the at least one actuator so that the insert evenly divides the airstream;
- moving the insert into a biasing position by adjusting the at least one actuator so that the insert unevenly divides the airstream;
- and
- moving the insert into a restricting position by adjusting the at least one actuator so that the insert at least partially restricts the airstream.
