An agricultural air seeder planting unit incorporates control valves that split air flow and change air direction from an air supply to air distribution hoses. The air flow of the control valves is automatically adjusted pneumatically by movement of a piston in response to a total pressure for a uniform velocity air flow from each of the control valves.

Flow control for agricultural implement pneumatic system

A pneumatic distribution system for use with agricultural equipment, such as air drills and air carts, includes hoses which may be held at a manifold connection having articulated control. The manifold connection may hold multiple couplers for hoses, and each of the couplers may be configured to allow substantial rotation in a first plane perpendicular to the ground. In addition, the manifold connection may be configured to allow substantial rotation in a second plane parallel to the ground. As a result, the manifold connection may be held proximal to a mechanical hitching point between agricultural equipment. This, in turn, may allow elimination of excess hose lengths and greater ease of handling when the agricultural equipment is separated and the hoses are disconnected.

Air pack manifold having articulated control

A pivoting hose support system for use with an agricultural implement is provided that includes a guide through which a hose(s) extends and that is arranged to pivot at an articulation point defined at connections between components that are movable through relatively large ranges of motion with respect to each other. The guide and the movable component may pivot about a common rotational axis and may be arranged upon different portions of a common pivot pin to which the guide may be axially fixed.
