Abstract
An agricultural implement system that may utilize a central press wheel inflation system to provide variable pressure to press wheels within multiple row units distributed across a width of the agricultural implement system. The agricultural implement system may automatically modify a shape or contact area of the press wheels using variations of press wheel pressure based on various sensor data and performance/behavior data of other row unit control systems. The central press wheel inflation system may provide one or more air lines coupled to the press wheels, allowing internal pressure of the press wheels to be adjusted, thus effectively creating a V-shaped or V-press-like second stage contact patch that may be beneficial in certain soil conditions.
